What to Ask a Coffee Supplier Before Placing an Order

By Viet Coffee Source Buying Guides

What to Ask a Coffee Supplier Before Placing an Order is a practical guide for importers, roasters, distributors, wholesalers, private-label brands and foodservice businesses evaluating a new coffee supply relationship. The questions asked before confirming an order can determine whether the shipment meets the required quality, quantity, packaging, documentation, delivery and commercial expectations.

A coffee offer should never be evaluated only by price per kilogram or a short product name such as Robusta, Arabica or specialty coffee. Two lots with similar descriptions may differ significantly in origin, crop period, processing method, defect level, screen size, moisture, cup quality, traceability, packaging and shipment readiness.

The buyer should convert general expectations into measurable specifications before requesting a quotation. A professional supplier should be able to explain what is being offered, which details are guaranteed, which values are indicative, how the lot will be inspected and what happens if the delivered product does not match the approved reference.

Asking structured questions also helps the supplier prepare a more accurate proposal. When origin, quality, volume, destination, packaging, shipment period and intended application are clear, unnecessary revisions and misunderstandings can be reduced.

Why supplier questions matter before ordering

Coffee is an agricultural product whose physical and sensory characteristics can change according to variety, farm conditions, harvesting, processing, drying, storage, sorting and crop season. A broad product label does not provide enough information for commercial approval.

Detailed questions help buyers:

Compare quotations on the same basis
Identify hidden specification differences
Confirm whether the coffee suits the intended product
Estimate the real landed cost
Evaluate operational and shipment risks
Define inspection and rejection procedures
Protect consistency across repeated orders
Build a documented approval process

Start by explaining the intended application

Before questioning the supplier, the buyer should explain how the coffee will be used. Coffee for commercial espresso, specialty filter, instant production, traditional phin brewing, dark retail blends and ready-to-drink beverages may require different specifications.

The supplier should know whether the order is intended for:

Local roasting
Espresso blends
Filter coffee
Vietnamese phin coffee
Instant coffee manufacturing
Private-label retail products
Foodservice supply
Cold brew or ready-to-drink production
High-caffeine products
Specialty or premium positioning

A clear application allows the supplier to recommend a more suitable species, origin, processing method, grade, screen size and sensory profile.

What coffee species is being offered?

The buyer should confirm whether the coffee is Robusta, Arabica or a blend. The species influences caffeine, body, acidity, aroma, price, roasting behaviour and final application.

Question	Why it matters	Possible follow-up
Is the lot Robusta or Arabica?	Defines the basic product category	Ask for botanical variety or cultivar
Is it a single species or a blend?	Affects consistency and labelling	Request the exact percentage composition
Is the composition fixed?	Prevents unnoticed changes between shipments	Ask how substitutions are controlled
Can the species be verified?	Supports product authenticity	Request traceability and lot documentation

Which origin and growing region does the coffee come from?

Country of origin alone may be too broad. Regional growing conditions influence density, flavour, harvest timing, processing and availability. Buyers should request the province, region, district, cooperative or producer level when commercially relevant.

Useful questions include:

Which country and region produced the coffee?
Is the lot from one region or blended across regions?
What is the approximate growing elevation?
Is the coffee linked to a farm, cooperative, mill or collection area?
Can the same origin be supplied again?
Are regional substitutions allowed?

Buyers sourcing from Vietnam can review Vietnamese coffee origins and regional production characteristics before defining their preferred supply area.

What variety or cultivar is included?

Variety information can be important for specialty coffee, differentiated Arabica, Fine Robusta and products marketed around origin. Commercial lots may contain several cultivars, while premium lots may be more narrowly defined.

The buyer should ask:

Which botanical variety or cultivar is included?
Is the lot single-variety or mixed?
Is the variety information documented or estimated?
Can the same variety composition be maintained?
Does the variety affect the quoted cup profile?

Which crop period is the coffee from?

Crop information helps the buyer evaluate freshness, storage time and replacement availability. A recently shipped lot is not necessarily newly harvested, and an older crop may still be commercially acceptable if it has been stored correctly.

Ask the supplier:

What is the harvest or crop period?
When was the coffee processed?
How long has it been stored?
Was it stored as parchment, dried cherry or green coffee?
Is the offered lot current crop, past crop or a blend?
How much of the same crop remains available?

How was the coffee processed?

The processing method affects flavour, body, sweetness, acidity, drying risk and roast performance. Common methods include washed, natural and honey processing, but suppliers may use additional fermentation or drying protocols.

Processing method	Potential commercial profile	Important buyer question
Washed	Cleaner structure and clearer acidity	How was fermentation controlled?
Natural	Heavy body, fruit and sweetness	How were cherries dried and defects removed?
Honey	Rounded body and caramel-like sweetness	How much mucilage was retained?
Controlled fermentation	Distinctive or intensified flavours	Is the process repeatable and documented?

The name of the processing method is not enough. Buyers should ask about fermentation duration, drying surface, drying time, moisture control and lot separation.

What grade and commercial classification apply?

Grade names vary by country, market and supplier. A label such as Grade 1, Grade 2, premium or specialty should be supported by measurable criteria.

The buyer should request:

The exact grade definition
The standard used for classification
Maximum defect allowance
Screen-size requirements
Moisture specification
Foreign-matter tolerance
Black and broken bean limits
Whether the specification applies to every bag or the shipment average

What is the defect specification?

Defects can affect roast consistency, flavour, yield and customer complaints. The supplier should explain how defects are counted and which defect standard is being used.

Defect area	Question to ask	Commercial importance
Full defects	What is the maximum count per sample size?	Supports grade comparison
Black beans	What percentage or count is allowed?	Can cause harsh and burnt flavours
Sour beans	How are they identified and limited?	May create unpleasant fermented notes
Broken beans	What tolerance is guaranteed?	Affects roasting uniformity
Foreign matter	What is the maximum permitted level?	Important for safety and processing
Insect damage	How is it measured and controlled?	Affects appearance and quality perception

What screen size is supplied?

Screen size influences bean appearance, roasting behaviour, product positioning and pricing. A screen claim should include the measurement method and tolerance.

Ask:

What is the target screen size?
What percentage remains above or below the stated screen?
Is the coffee mechanically screened?
Is the screen distribution included in the specification?
Will the shipment be uniform across all bags?
Can a pre-shipment screen analysis be provided?

What are the moisture and water-activity limits?

Moisture is a critical green-coffee specification. Excessive moisture can increase storage risk, while very low moisture may affect quality, weight and roasting performance. Water activity can provide additional information about stability.

Questions should include:

What moisture range is guaranteed?
Which measurement method is used?
Is moisture checked before stuffing?
Can a certificate or inspection result be provided?
Is water activity measured?
What happens if the result is outside specification?

What cup profile should the buyer expect?

Physical specifications do not fully describe flavour. The buyer should request a clear sensory description and test the coffee in the intended brewing method.

A useful cup specification may cover:

Aroma
Flavour notes
Sweetness
Acidity
Body
Bitterness
Aftertaste
Cleanliness
Balance
Undesirable flavours

The buyer should ask whether the profile is descriptive or contractually guaranteed. Broad descriptions such as strong, smooth or premium should be converted into clearer sensory expectations.

How is the coffee evaluated?

The supplier should explain the quality-control method used before offering, contracting and shipping the coffee.

Ask:

Is the coffee cupped by trained personnel?
Which roasting and cupping protocol is used?
How many samples are taken from the lot?
Is the offered sample representative of the complete lot?
Is a pre-shipment sample available?
Can the buyer approve the final sample before loading?
Are physical and sensory results recorded?

Is the sample representative of the shipment?

A good sample is useful only when it accurately represents the commercial lot. Buyers should clarify how the sample was prepared and whether the same coffee is reserved.

Important questions include:

Was the sample drawn from the exact offered lot?
Was it prepared as a hand sample or production sample?
How many bags or points were sampled?
Is the lot already assembled?
Will the shipment be matched to the approved sample?
How long is the lot reserved after sample approval?

Can the buyer receive a pre-shipment sample?

A pre-shipment sample allows the buyer to compare the final prepared lot with the approved offer sample before loading. This is particularly important when the coffee must be milled, screened, sorted or blended after the initial approval.

The buyer should define:

Who draws the pre-shipment sample
When it is sent
How approval is documented
How long the supplier waits for approval
What happens if the sample is rejected
Whether reprocessing is possible
Who pays for replacement samples and delays

What quality is contractually guaranteed?

The buyer should distinguish between marketing information, typical values and binding specifications. Only clearly written contractual requirements can be reliably enforced.

Information type	Meaning	Buyer action
Typical value	Common but not guaranteed result	Do not treat it as a fixed specification
Target value	Desired production objective	Ask for permitted tolerance
Maximum or minimum	Contractual boundary	Confirm measurement method
Representative sample	Physical reference for approval	Define storage and comparison process
Guaranteed specification	Binding commercial requirement	Include it in the contract

How is traceability managed?

Traceability helps connect the shipment to its origin, processing location, storage records and quality-control results. The required level depends on the product and destination market.

Ask the supplier:

Can the coffee be traced to a region, cooperative, mill or farm?
Does every bag carry a lot code?
Are processing and warehouse records maintained?
Can the supplier connect the invoice, packing list and lot numbers?
How are mixed lots documented?
How long are records retained?

Which quality and compliance documents are available?

Document requirements depend on origin, destination, product type and buyer policy. The supplier should confirm what can be provided before the order is placed.

Possible documents include:

Commercial invoice
Packing list
Certificate of origin
Phytosanitary certificate
Fumigation certificate when required
Quality or weight certificate
Moisture report
Inspection certificate
Bill of lading
Traceability documents
Food-safety or management-system certificates
Sustainability or programme-specific records

Buyers can review coffee quality-control, traceability and compliance considerations when preparing their supplier checklist.

Can the supplier support destination-specific requirements?

The buyer should not assume that a standard export document set will satisfy every destination. Import rules, labelling requirements and customs procedures may vary.

Ask:

Has the supplier shipped to the destination before?
Which documents were used?
Are any destination-specific certificates required?
Can the supplier coordinate inspection or fumigation?
Who is responsible for confirming import requirements?
Can documentation drafts be reviewed before shipment?

What packaging options are available?

Packaging affects moisture protection, contamination risk, handling, branding and cost. The buyer should define both the inner product packaging and the outer transport format.

Packaging option	Typical use	Question to ask
Jute bag	Standard green-coffee export	What is the bag weight and liner option?
Jute bag with inner liner	Improved moisture and odour protection	What liner material and closure are used?
Hermetic liner	Premium and specialty protection	Is the liner new, sealed and food-contact suitable?
Bulk bag	Industrial handling	What is the net weight and loading method?
Retail pouch	Roasted or ground private-label coffee	What barrier, valve and sealing structure are used?

What are the exact bag and carton specifications?

Packaging should be described in measurable terms rather than general phrases such as export standard.

Confirm:

Net weight per bag
Gross weight per bag
Bag material
Inner-liner type
Closure method
Printing or marking
Lot coding
Pallet use
Carton dimensions
Units per carton
Maximum stacking conditions

Can customised packaging be produced?

Private-label and branded orders may require printed bags, retail pouches, labels, cartons or gift sets. Customisation can affect minimum order quantity, lead time and cost.

Ask:

Which packaging formats can be customised?
What is the minimum quantity per design?
Who provides the artwork?
Which file format and printing specifications are required?
Is a printed proof or mock-up provided?
Who owns unused packaging materials?
How are packaging changes managed?

What is the minimum order quantity?

The minimum order quantity may differ according to green coffee, roasted coffee, ground coffee, packaging type and customisation level.

Buyers should clarify:

Minimum quantity per coffee lot
Minimum quantity per specification
Minimum quantity per packaging design
Minimum quantity per language version
Whether mixed products can share one shipment
Whether trial orders are available
How pricing changes at different volumes

How much coffee is currently available?

A supplier may be able to provide a sample without having enough stock for the requested order. Availability should be confirmed before the buyer invests time in testing and development.

Ask:

How much of the exact lot is available?
Is the quantity already processed and stored?
Is any portion reserved for another buyer?
How long can the lot be held?
Can additional volume be produced?
Would additional volume come from the same lot or a new lot?

Can the supplier maintain repeat-order consistency?

Repeatability is critical for brands and roasters that need a stable product throughout the year. Agricultural variation cannot be eliminated completely, but it can be managed through specifications, blending and reference samples.

Ask the supplier:

Can the same origin and grade be supplied throughout the year?
How are crop changes managed?
Is blending used to maintain consistency?
Will substitutions require buyer approval?
Can a reference sample be retained?
How much variation is considered acceptable?

What is the quoted price based on?

A price is meaningful only when the product specification, quantity, packaging, delivery term and payment conditions are clear. A lower quotation may exclude services included in another supplier’s offer.

Ask:

Which exact specification does the price cover?
What quantity is assumed?
Which packaging is included?
Which Incoterm is used?
Which port or delivery point applies?
How long is the quotation valid?
Can the price change before contract signing?
Are inspection, documentation and loading charges included?

Which Incoterm is offered?

The Incoterm defines how costs, responsibilities and risks are divided between buyer and seller. Buyers should not compare prices using different terms as though they were equivalent.

Commercial area	Question	Reason
Delivery point	Where does the seller’s responsibility end?	Defines risk transfer
Freight	Is ocean or inland freight included?	Affects landed cost
Insurance	Who arranges cargo insurance?	Clarifies protection responsibility
Export clearance	Who prepares export customs procedures?	Prevents documentation gaps
Destination charges	Which costs remain for the buyer?	Supports accurate budgeting

What payment terms are required?

Payment conditions should be clear before the buyer confirms the order. The appropriate structure depends on the relationship, order value, risk profile and banking arrangements.

Questions may include:

Is an advance payment required?
When is the balance due?
Is payment linked to documents, loading or delivery?
Can a letter of credit be used?
Which bank charges are paid by each party?
Which currency is accepted?
What happens if shipment is delayed?
Are deposits refundable under any condition?

What is the production and preparation lead time?

Lead time may include milling, grading, sorting, roasting, grinding, packaging, documentation, inspection and inland transportation. Buyers should request a realistic schedule rather than a general promise of fast delivery.

Ask:

When can production begin?
How long does final preparation require?
When will the pre-shipment sample be ready?
How long is needed after approval?
When can the container be booked?
Which steps may cause delays?
Is the timeline guaranteed or estimated?

What is the expected shipment window?

The contract should define a shipment period or latest shipment date. A vague statement such as shipment soon can create operational and inventory problems.

The buyer should confirm:

Earliest shipment date
Latest shipment date
Port of loading
Expected transit time
Whether transshipment is possible
Container availability risks
How delays will be communicated

How will the coffee be transported and loaded?

Container condition, loading method and protection against moisture are important for preserving quality during transit.

Ask:

Will the shipment use a full container or shared container?
Who inspects container cleanliness and dryness?
Are moisture-control materials used?
Is the container lined?
How are bags stacked and secured?
Are loading photographs provided?
Is the seal number recorded in the documents?

What inspection options are available?

Inspection may be conducted by the supplier, buyer, independent surveyor or a combination of parties. The inspection scope should be agreed before the order.

Possible inspection areas include:

Quantity and weight
Bag count
Packaging condition
Moisture
Screen size
Defect count
Cup quality
Container condition
Loading supervision
Document verification

The buyer should ask who selects the inspector, who pays the cost and whether the inspection result is final and binding.

How are weight differences handled?

Agricultural products and export packaging may involve small weight variations. The contract should state the permitted tolerance and the basis for invoicing.

Confirm:

Whether pricing is based on net or gross weight
Permitted weight tolerance
Whether weight is determined at origin or destination
Which scale or certificate is accepted
How shortages are compensated
How excess quantity is invoiced

What happens if the shipment fails specification?

A clear claims procedure is one of the most important parts of a supply agreement. The buyer should not wait until a problem occurs to discuss remedies.

Ask:

How many days does the buyer have to submit a claim?
Which evidence is required?
Who draws the claim sample?
Can an independent laboratory or surveyor be used?
What remedies are available?
Can the coffee be replaced, discounted or returned?
Who pays storage, inspection and return costs?
How are sensory disputes resolved?

How is the approved sample retained?

A sealed reference sample can support dispute resolution by providing a physical benchmark. Both parties should agree on how it is prepared, identified and stored.

The process may define:

Sample weight
Number of duplicate samples
Seal and signature method
Lot identification
Storage conditions
Retention period
Party responsible for custody
Procedure for opening the sample

Does the supplier have relevant export experience?

Experience does not guarantee perfect performance, but it can indicate familiarity with documentation, freight, destination requirements and commercial communication.

Useful questions include:

Which markets has the supplier served?
Which product types have been exported?
Can trade references be provided?
How long has the company exported coffee?
Does the company manage documentation internally?
Who will be the operational contact after contract signing?

Who is responsible for communication?

The buyer should know who manages sales, quality, production, documents and shipment. Relying on one unidentified communication channel can create delays.

Confirm:

Primary commercial contact
Quality-control contact
Documentation contact
Logistics contact
Preferred communication method
Expected response time
Escalation contact for urgent problems

Can the supplier provide references or shipment history?

References can help the buyer assess reliability, but confidential customer information should be handled appropriately. Suppliers may provide anonymised shipment history, market experience or references with permission.

Ask for:

Years of export activity
Main destination regions
Typical shipment volumes
Experience with similar specifications
Experience with private-label production
References from comparable buyers when available

What certifications does the supplier hold?

Certifications may relate to food safety, quality management, sustainability, organic production or specific customer programmes. The buyer should verify the scope, validity and relevance of each certificate.

Ask:

Which certifications are currently valid?
Which facility or product is covered?
What is the certificate expiry date?
Can the certificate be verified?
Does it apply to the offered lot?
Are additional certified volumes available?

Can sustainability information be provided?

Sustainability expectations vary by buyer and market. Some buyers need basic origin transparency, while others require detailed environmental, social or farm-level records.

Possible questions include:

Is the coffee traceable to producer or region?
Are farm practices documented?
Are labour and social requirements monitored?
Is deforestation-risk information available?
Can geolocation or farm data be provided when required?
Are sustainability claims independently verified?

Can the supplier support private-label development?

Private-label orders require coordination beyond coffee sourcing. The supplier may need to manage roasting, grinding, packaging, artwork, coding, cartons and finished-product testing.

Ask:

Which product formats can be produced?
Can custom blends be developed?
Which roast levels are available?
Can coffee be supplied whole bean and ground?
Which retail packaging formats are supported?
Can labels and cartons be printed?
What are the development and approval stages?
What is the private-label minimum quantity?

Can the supplier provide roasting and grinding specifications?

For roasted coffee, the buyer should request measurable information rather than only light, medium or dark descriptions.

Questions may include:

What roast colour range is targeted?
How is roast colour measured?
Is the coffee roasted separately or blended before roasting?
What is the expected degassing period?
Which grind range is supplied?
How is particle distribution checked?
Can a reference roast be approved?

What shelf life is offered?

Shelf life depends on product type, roast, grind, packaging barrier, valve system, storage and validation method. A printed date should be supported by a reasonable quality basis.

Ask:

What shelf life is declared?
From which date is it calculated?
How was it validated?
What storage conditions are required?
How much shelf life will remain at shipment?
Does opening the package change the recommendation?

Which product testing is performed?

Finished-product testing may include physical, sensory, microbiological, packaging and shelf-life controls depending on the product.

The buyer can ask:

Which tests are performed on every batch?
Which tests are periodic?
Are external laboratories used?
Can certificates of analysis be provided?
How are nonconforming results managed?
Are retain samples stored?

Can mixed products be loaded in one shipment?

Buyers may want to combine different grades, origins, bag sizes or finished products in one container. This can improve purchasing flexibility but increases loading and documentation complexity.

Confirm:

Whether mixed loading is permitted
Minimum quantity per product
How products are separated inside the container
How bag markings and lot codes differ
Whether mixed loading changes the price
How the packing list will identify each item

What is included in the export service?

The supplier should explain which activities are included in the quotation and which require additional payment.

Service	Question	Potential additional cost
Quality preparation	Are sorting and grading included?	Reprocessing or premium selection
Packaging	Is the inner liner included?	Hermetic or custom materials
Documentation	Which certificates are included?	Special inspection or legalisation
Transport	Is inland movement to port included?	Long-distance trucking
Loading	Are stuffing and supervision included?	Independent surveyor
Freight	Is ocean freight included?	Rate changes and surcharges

Buyers can review coffee export, packaging, documentation and shipping solutions when preparing their order and logistics requirements.

How should quotations be compared?

Supplier quotations should be normalised before comparison. The lowest headline price may not represent the lowest final cost if quality, packaging, inspection, freight or payment terms differ.

Compare:

Species and origin
Grade and defects
Screen size
Moisture
Cup profile
Crop period
Packaging
Quantity
Incoterm
Shipment period
Payment terms
Included documents
Inspection terms
Claims procedure

Warning signs before placing an order

Certain communication patterns may indicate elevated commercial risk. A warning sign does not always prove that the supplier is unreliable, but it should lead to further verification.

The specification changes repeatedly without explanation
The supplier avoids identifying the exact lot
The sample is not linked to available stock
Only vague quality terms are provided
Documents cannot be shown in draft form
Payment is requested before basic company verification
The price is far below comparable offers without a clear reason
The supplier refuses independent inspection
Shipment promises are unrealistic
Contractual remedies are not accepted
Bank-account information changes unexpectedly
Company details are inconsistent across documents

Documents to review before payment

The exact documents depend on the transaction, but the buyer should verify the supplier and commercial offer before transferring funds.

Possible review items include:

Company registration information
Tax or export registration details
Proforma invoice
Product specification
Sample approval record
Sales contract
Bank-account confirmation
Packaging specification
Shipment schedule
Relevant certificates

Final assessment

Before placing a coffee order, buyers should ask detailed questions about product identity, origin, processing, physical quality, cup profile, traceability, packaging, documentation, pricing, payment, shipment and claims procedures. A short product description and attractive price are not enough to protect the buyer or ensure that the coffee is suitable for the intended market.

The strongest supplier relationships begin with measurable expectations. Specifications should clearly separate guaranteed values from typical information, and approved samples should be connected to the exact commercial lot whenever possible.

Buyers should also examine the complete transaction rather than only the coffee price. Packaging, inspections, documents, freight responsibilities, lead time, payment structure and remedies for nonconformity can significantly change the commercial value and risk of an order.

Importers, roasters, distributors, foodservice businesses and private-label brands seeking Vietnamese Robusta, Fine Robusta, Arabica or custom coffee products can submit a wholesale coffee inquiry with the required species, origin, grade, processing method, quality specification, packaging, volume, destination and shipment period.
