CHINA SOURCING / BUYER GUIDE
How to compare Chinese suppliers
Put quotations on the same specification, quantity and delivery basis. The goal is to make differences visible before selecting a supplier.

Define the product before scoring the supplier.
A quotation comparison is unreliable when one factory prices a different material, tolerance, accessory set or package. Write down the product reference, intended use, materials, dimensions, quantity, variants and packaging. Give the brief a date or revision so later changes can be traced.
When a supplier suggests an alternative, record it as an alternative. Do not silently treat a different product as a cheaper offer for the original specification. A useful comparison preserves the reason for each price difference.
Compare these fields side by side.
| Field | Why it matters | Question to ask |
|---|---|---|
| Supplier role & identity | Identifies the company you are actually dealing with. | Who manufactures, invoices and receives payment? |
| Specification | Shows whether offers describe equivalent products. | Which material, dimensions, finish and accessories are included? |
| MOQ & variants | Determines whether the order is feasible. | Is the minimum per order, model, color or size? |
| Sample & tooling | Separates early costs from production pricing. | What is charged, what is supplied and what needs approval? |
| Production timing | Shows dependencies behind the delivery estimate. | Does the timeline start after sample approval, deposit or another event? |
| Quality & packing | Connects price to acceptance requirements. | Which checks and packaging details are agreed? |
| Price basis | Exposes costs that are otherwise easy to miss. | Which charges and delivery stages are included? |
Distinguish a statement from evidence.
A supplier’s catalogue, message or certificate image can be a starting point for a question, but it is not the same as verifying a specific claim. Record what information has been provided, what has been checked and what remains unconfirmed. Request evidence relevant to the product and the company you would contract with.
Supplier screening, a factory visit, a product sample and an order inspection answer different questions. A good sample does not by itself prove production capacity, and a factory visit does not approve every item in a future order. Agree which checks are needed for the decision at hand.
An illustrative comparison: do not rank by unit price alone.
Consider two hypothetical suppliers quoting 500 units of the same item. Supplier A includes the specified retail box. Supplier B quotes a lower unit price but excludes the box and has not confirmed the requested material. The immediate next step is to clarify Supplier B’s scope, rather than declare it the cheaper equivalent.
Keep the unresolved points visible in the comparison. Once both offers match the brief, compare the total cost and the remaining differences in timing, samples and agreed quality requirements. This example illustrates a method; it is not a TMD client case.
Approve a version, then control changes.
After sampling, capture feedback against the specification. Record the approved version, any condition that still needs attention and who approved it. If a supplier changes the material, component or packaging, revisit the affected requirement and ask about its cost and timing implications.
Before purchasing, confirm that the order documents refer to the same approved requirements. During production, use an issue log so a proposed change does not disappear in a long message thread. Important changes need an explicit decision.
Use a working comparison sheet.
Our blank template provides fields for supplier identity, specification, quantity, price, samples and open questions. Add columns for your own product’s requirements and keep supporting files with the same reference.
When can a sourcing agent help?
An agent can help clarify the brief, communicate with suppliers, organize quotations and coordinate samples and purchasing. You still need to decide which requirements matter and approve the final product and order. See TMD’s product sourcing service for the proposed inputs, records and scope.
