Sample Discrepancy: How to Document It and What to Demand

07.11.2026·6 min read·Delivery Pro China

Shipment discrepancy from approved sample: how to document the deviation, what to include in the contract, and how to negotiate compensation. A practical breakdown.

In brief: If a received shipment differs from the approved sample, the outcome of a dispute with the supplier depends on two things: whether the sample parameters were documented before production, and whether the deviation was identified before the goods left China. Without a written record of compliance criteria, negotiations are conducted from a position of request rather than contractual right.

Why Verbal Sample Approval Is a Trap

The most common mistake when working with Chinese suppliers: the sample is physically approved, both parties agreed to "make it the same," but the parameters are not recorded in writing anywhere. During production, the supplier relies on their own interpretation of "the same." During a dispute, they appeal precisely to that ambiguity.

Sample compliance must be documented and must precede the launch of production. The minimum set:

• photographs of the sample with annotations for key parameters;
• a specification table: material, color (by Pantone, RAL, or the manufacturer's exact code), dimensions with tolerances, functions, labeling;
• written confirmation from the supplier that the shipment will be produced in accordance with these parameters.

This document becomes an annex to the contract and the basis for any claims.

Critical vs. Non-Critical Deviation: What Is the Difference

Not all discrepancies from the sample are equal, and the approach to them should differ accordingly.

A non-critical deviation does not affect the function, safety, or saleability of the goods. Examples: a minor shade shift within the same color family, a changed font on the label, a different texture on the inner packaging. In these cases, it is reasonable to consider partial compensation or a discount on the shipment.

A critical deviation affects the material, construction, stated technical specifications, or safety. Examples: a different fabric composition, a missing function on a device, different dimensions of a part that must fit a specific seat. Here, replacement of the shipment or a full return is justified – provided the contract allows for it.

What the Contract Must Contain to Protect Your Interests

A contract with a Chinese supplier must explicitly describe:

1. A reference to the approved sample – its description, SKU, or photo number from the specification.
2. A list of compliance parameters and the acceptable tolerances for each.
3. The procedure for handling a detected discrepancy: timelines for notifying the supplier, who bears the costs of replacement or return, what constitutes sufficient grounds for a claim.
4. A dispute resolution mechanism: negotiations, arbitration, the right to withhold payment for part of the shipment.

Without these clauses, you have no contractual position – only negotiations whose outcome depends on the supplier's willingness to engage.

How to Document a Discrepancy Before Shipment Leaves China

If a shipment is inspected at a warehouse in China before consolidation and dispatch, a discrepancy from the sample can be identified at this stage. This is critically important: while the goods are still on Chinese territory, you have the opportunity to stop the shipment, request replacement of defective units, or renegotiate terms without incurring additional logistics costs.

Inspection at the acceptance stage includes:

• comparing the physical parameters of the shipment against the approved specification;
• photo documentation of each identified deviation;
• drawing up a discrepancy report with specific line items and the number of affected units;
• notifying the supplier with written confirmation.

If a discrepancy is only identified after delivery to the destination country, the evidentiary base becomes more complex. The supplier may claim that the goods were damaged in transit or substituted after dispatch. The costs of return or replacement in such cases frequently become the subject of a prolonged dispute.

The warehouse in Guangzhou through which shipments pass before dispatch serves exactly this purpose: to identify a problem where it can still be resolved without crossing a border.

Discount Instead of Return: When It Is the Rational Choice

Returning a shipment from abroad is a costly, time-consuming, and administratively complex procedure. In most situations involving a non-critical deviation, it is more economically reasonable to:

• document the deviation and its impact on resale or use;
• assess the actual financial loss;
• present the supplier with a specific compensation amount with justification;
• incorporate an updated specification into the next order.

A supplier focused on continuing the relationship will generally agree to partial compensation. If they refuse to acknowledge an obvious deviation, that is itself a signal about the reliability of the counterparty – one worth factoring into planning for future shipments.

Compliance Checklist for Future Shipments

After any quality incident, it is worth updating the approval workflow. A basic checklist:

• [ ] Sample parameters are recorded in writing and confirmed by the supplier before production begins
• [ ] The specification is an annex to the contract
• [ ] The contract includes clauses on acceptable tolerances and the claims procedure
• [ ] A pre-shipment inspection in China is in place
• [ ] A person responsible for acceptance and photo documentation at the warehouse is designated
• [ ] A deadline for notifying the supplier upon detection of a deviation is established

Frequently Asked Questions

What should I do if the supplier denies any discrepancy from the sample? If the sample parameters are documented and you have an inspection report with photographs, negotiations are built on specific facts rather than words. If there is no documentation, you will need to proceed through negotiations or arbitration, where a position without evidence is weaker.

Who bears the costs of returning or replacing a defective shipment? This is determined by the contract. If it specifies the procedure for handling a sample discrepancy and the supplier violated the specification, the costs fall on them. If the contract is silent on this point, costs become a matter of negotiation and the outcome is unpredictable.

Is it possible to agree on a discount rather than a return? Yes, and in most cases this is the more practical solution for a non-critical deviation. Document the deviation, assess the actual loss, and present a specific compensation amount. This is faster, less expensive, and preserves the working relationship with the supplier.

How does inspection at the Guangzhou warehouse help prevent such situations? Pre-shipment inspection makes it possible to identify a discrepancy from the sample before the goods have left China. At this stage, it is still possible to replace units, repack, or halt the shipment without incurring additional customs and logistics costs.
