Direct answer: separate sample correction from production approval. Record which agreed requirements the sample did not meet, ask what a revised sample will change and clarify its cost, evidence and payment conditions. If a supplier asks for a production deposit first, obtain a written explanation of what that payment authorizes and what remains unapproved. There is no universal deposit rule that makes an unresolved sample acceptable.
Identify the difference before discussing another payment
A custom sample can arrive with a different material, finish, dimension or assembly from what the buyer expected. Start by comparing it with the written request. Separate a requirement the supplier accepted from a feature that was never clearly agreed.
Keep the sample reference, relevant photos and the supplier’s confirmation together. A vague statement such as “the quality is bad” makes a corrective discussion difficult. Describe what you observed and which reference it differs from. Do not infer an engineering cause or assign a legal remedy from photographs alone.
Use a sample correction table
This blank framework helps identify the next question. It does not set a defect threshold or establish a supplier’s responsibility.
| Item | Record | Clarify next |
|---|---|---|
| Agreed reference | Specification, drawing revision or accepted finish sample | Did both parties use the same reference? |
| Observed difference | Specific material, appearance, dimension or function question | Does the supplier agree with the observation? |
| Proposed correction | What will change and what will remain unchanged | Can a revised sample demonstrate it? |
| Cost and payment | Amount, purpose and written conditions of the requested payment | Is it for a sample, setup, material or production? |
| Approval point | Evidence required before the next commitment | What is still not authorized? |
Ask what the first sample was intended to demonstrate
Some samples demonstrate dimensions while using a provisional material or finish. Others are intended as a final production reference. The distinction should be agreed before the sample order; if it was not, clarify it now rather than treating your assumptions as a shared approval.
For a revised sample, state the intended material, construction, finish and any limitations. Ask the supplier to identify any feature that cannot yet be shown. The drawing acknowledgment checklist helps turn an unanswered requirement into accepted, proposed deviation or open.
Separate correction costs from production commitment
A supplier may explain that a change requires different tooling, setup or material purchasing. Ask for the specific reason and the scope included in the requested payment. An explanation is useful information, but it does not replace your decision about whether the commitment fits the evidence.
Do not assume that paying a production deposit preserves a separate sample-approval gate. Ask what work starts after payment, whether materials are purchased, and which decisions remain pending. Clarify any cancellation, unused material or correction terms in the agreement and seek appropriate professional advice where needed.
The sample cost comparison guide can organize the quotation. This page concerns a sample that failed to answer the agreed questions, rather than comparing ordinary sample prices.
Agree a revised sample that answers the open question
- Name the current sample and the reference it was meant to follow.
- List the specific corrections requested.
- Ask the supplier to confirm feasibility and any proposed alternative.
- Agree the revised sample’s cost and evidence before authorizing it.
- Record what would support approval and which points still require review.
Use the smallest next commitment that can provide useful evidence. Another sample with an undefined correction can repeat the same uncertainty. If the issue needs specialist testing, arrange a suitable assessment rather than relying on a visual example.
Choose between clarify, revise, compare or pause
Continue clarification when the original requirement is ambiguous. Request a revised sample when its scope can demonstrate a feasible correction. Compare another supplier when you need a realistic alternative, keeping the same requirements so that the comparison is meaningful. Pause when critical differences remain unanswered and the next payment would authorize work you are not ready to accept.
Once a sample is suitable for approval, create an approved-sample record. Approval should name the exact version and any exceptions; it is not proof that every later unit will match.
Clarify the next sample decision
If useful, send a product link or short description, target quantity, destination country and business email. These four basics help frame supplier and sample questions. Review small-batch testing support; any coordination and checking work needs an agreed scope.
Frequently asked questions
Is a production deposit before a revised sample normal?
There is no universal rule. Ask what the payment covers, which work it authorizes and what remains subject to approval. Evaluate the actual written terms.
Should a corrected sample always be free?
Do not assume that. Review the original agreement, the requested correction and the supplier’s explanation. Clarify costs before authorizing another sample.
Can photos settle the quality question?
They may show certain differences but may not establish material, function or technical performance. Choose evidence suitable for the question.
Does this checklist guarantee a refund or successful correction?
No. It organizes requirements and decisions. Rights, remedies and technical conclusions require their own appropriate assessment.
