A sourcing request becomes much easier to act on when the supplier can understand exactly what you want to buy.
"Please quote this product" is usually not enough.
A supplier may still need to guess the material, dimensions, quantity, packaging, customization, sample requirements and delivery assumptions. Different suppliers can then quote different versions of the same idea, making the prices difficult to compare.
A practical sourcing brief reduces those assumptions before the quotation stage.
This guide explains what international buyers should include when asking suppliers in China to source or quote a product.
1. Start with a clear product identity
Give the supplier enough information to identify the item you actually want.
Useful references can include:
• product name
• model number or SKU, if available
• reference photos
• drawings
• existing sample photos
• product links used only as a visual reference
• intended application
• target market or customer type, where relevant
Do not assume a photo answers every specification question.
Two products can look almost identical while using different materials, thicknesses, internal components or production processes.
If you do not yet know the exact specification, say which points are fixed and which points are still open for supplier suggestions.
2. Write down the specifications that affect the quote
The supplier should know which product characteristics are mandatory.
Depending on the item, your sourcing brief may include:
• dimensions
• material
• colour
• finish
• thickness
• capacity
• weight range
• function
• power or voltage requirement
• components and accessories
• logo or branding requirements
• printing method
• tolerances already agreed by your technical team
• required documentation or testing requested by your market or customer
Only include requirements you actually need.
A long document filled with unnecessary specifications can create as much confusion as a brief with too little information.
When a point is uncertain, mark it as open for confirmation instead of inventing a value.
3. State the quantity clearly
Quotation conditions can change significantly with quantity.
Your request should distinguish between:
• sample quantity
• first trial order quantity
• expected bulk order quantity
• estimated repeat volume, if it is genuinely known
Do not present an uncertain future forecast as a guaranteed purchase commitment.
If you are testing the market, say so.
For products with multiple colours, sizes or models, show the quantity by variation rather than only giving one total number.
Example:
Model A — Black — 500
Model A — White — 300
Model B — Black — 200
This allows suppliers to understand the production mix before quoting.
4. Explain customization separately from the standard product
If you need an OEM, private-label or customized version, separate the changes from the supplier's standard item.
List each requested change, such as:
• logo position
• logo size
• packaging artwork
• colour change
• component change
• mould or tooling requirement
• label content
• manual language
• accessory set
• carton marking
Ask the supplier to identify which changes affect minimum quantity, tooling or setup cost, sample process, production time and packaging requirements.
Do not assume every customization is included in a standard unit price.
5. Describe packaging before comparing quotations
Packaging can affect product cost, shipping volume and damage risk.
If packaging is important to the project, include requirements such as:
• individual bag or box
• inner carton
• master carton
• protective foam or insert
• retail packaging
• barcode label
• carton mark
• pallet requirement
• maximum carton weight, if your receiving operation has one
If the packaging design is not final, say whether the supplier should quote standard factory packaging first or estimate a custom packaging option separately.
This makes it easier to understand what is included in each quotation.
6. Tell the supplier where the goods are going
Destination information can change the commercial discussion even before final freight is booked.
At minimum, provide:
• destination country
• destination city or port, if known
• whether you need only an ex-factory product quote or also a transport option
• any special receiving requirement you already know
If you request a quote using an Incoterms® rule, write the rule together with the agreed named place or port rather than using only a three-letter abbreviation. ICC publishes the current Incoterms® 2020 rules and guidance on buyer and seller responsibilities.
If the delivery term has not yet been agreed, mark it as open instead of forcing suppliers to make different assumptions.
7. Define the sample requirement
A sourcing brief should explain whether you need a sample before bulk production.
Specify:
• how many samples you need
• whether a standard sample is acceptable
• whether you need logo or packaging customization on the sample
• which specifications the sample must demonstrate
• where the sample should be sent
• whether the sample will become the reference for later approval
Keep a record of the exact sample version you approve.
A later production discussion becomes difficult if the buyer and supplier are referring to different sample revisions.
8. Separate mandatory requirements from preferences
One of the simplest ways to improve a sourcing brief is to label each requirement.
Mandatory — the product cannot be accepted without this requirement.
Preferred — desirable, but alternatives may be considered.
Open — the buyer wants the supplier to propose an option or provide information.
This helps a sourcing team shortlist suppliers without rejecting useful alternatives for the wrong reason.
9. Ask suppliers to quote the same fields
A quotation is easier to compare when every supplier answers the same questions.
Ask for the fields that matter to your project, such as:
• exact product quoted
• specification or model reference
• unit price
• currency
• quoted quantity
• minimum order quantity
• sample availability
• sample cost, if any
• packaging included in the price
• customization cost, if applicable
• tooling or setup cost, if applicable
• production lead-time estimate
• quotation validity
• payment terms offered
• delivery term and named place
• exclusions or assumptions
A low number in the unit-price column is not a complete quotation if other assumptions are different.
10. List the questions that are still unresolved
A useful sourcing brief does not pretend everything is already known.
Create an Open Questions Section.
Examples:
• Is this material available in the required thickness?
• Can the supplier meet the target colour?
• Is a new mould required?
• What packaging is currently standard?
• Can the supplier provide a sample with the requested branding?
• Which production step limits the minimum quantity?
This gives the supplier a clear place to respond instead of hiding uncertainty inside a quotation.

A better brief creates a better comparison
The goal of a sourcing brief is not to make a request look complicated.
It is to make different supplier responses easier to understand and compare.
