Before paying for a sample from a China supplier, agree on the work and the deliverable behind the charge. A stock item, a modified existing product and a development sample can involve different preparation, testing and shipping arrangements. A useful sample quote lets you see what you are buying, what remains unknown and whether a future order credit has actually been agreed.
The decision before the payment
This guide covers commercial confirmation for ordinary manufactured samples. ITA’s pro forma invoice guidance identifies the quoted items, prices, payment terms, shipment estimate and validity as useful information. Its total export price guidance distinguishes product cost from transport and other charges. The sample-specific checklist and fictional arithmetic below are CZ Overseas recommendations, not an official sample-price or refund policy.
Payment does not establish sample approval, market compliance or readiness for mass production. Those decisions need their own evidence and the sample approval process.
1. Identify the exact sample deliverable
State the model, requirement or drawing revision, quantity and unit, material, finish and intended evaluation. Ask whether the quote covers a stock sample, modification of an existing item or new development. Record which aspects the supplier has confirmed and which still depend on technical review.
A catalogue photograph is not a controlled sample specification. If a key dimension or performance requirement is unresolved, identify the missing input and its owner before authorising work. Use a specification brief when the requirement needs more detail.
2. Compare costs against the same scope
| Charge | Confirm | Do not assume |
|---|---|---|
| Sample units | Price per stated unit, quantity and revision | The same price for a later production order |
| Preparation or tooling | One-time work, deliverable and reuse terms | Tool ownership, exclusivity or unlimited revisions |
| Testing | Who tests, what is tested and what evidence is supplied | Approval for every destination market |
| Packing and shipping | Included packaging, route, recipient and paying party | Every destination or additional handling charge |
A single bundled price can still work if its inclusions and exclusions are clear. Ask whether a charge repeats when ordering another sample of the same revision. Keep tool ownership and usage permissions as separate written questions; payment alone is insufficient evidence of an agreed ownership arrangement.
3. Align payment and delivery triggers
Identify who approves the sample scope, who checks receipt of funds and which conditions start the preparation schedule. If both payment and a frozen specification are needed, write both into the record. Distinguish an estimated completion date, dispatch date and arrival estimate rather than treating them as interchangeable.
If you have authorised only a feasibility review, do not let the record imply that full development is approved. Reconfirm price and timing when the product revision or quantity changes, then reconcile the current version with the pro forma invoice checklist.
4. Make any future credit specific
A cash refund, a credit against a later order and a waived repeat-sample charge are different outcomes. Ask which one is offered. For an order credit, record the eligible product or project, qualifying order, quantity or value condition, deadline, currency, amount or permitted charge, approving contact and the document on which it will appear.
If no condition is agreed, mark it unresolved. Do not deduct a possible future credit from the present payable amount. Ask separately what happens if the sample fails the agreed evaluation. Conflicting terms or a dispute need an authorised commercial or professional review; this checklist does not determine a legal refund entitlement.
5. Calculate a confirmed subtotal without hiding unknowns
Fictional worked example: the supplier confirms two samples at USD 80.00 per piece, a one-time preparation charge of USD 40.00 and courier charges of USD 30.00 for the shipment. Packaging is explicitly included in the sample unit price, with no separately charged packaging amount. All figures are in USD; no currency conversion is involved.
Confirmed supplier-charge subtotal = quantity × sample unit price + preparation + separately billed packaging + courier. Here: 2 pieces × USD 80.00/piece + USD 40.00 + USD 0.00 + USD 30.00 = USD 230.00, shown to two decimal places. The zero is a confirmed packaging inclusion, not a missing value.
This example excludes destination duties and taxes, unagreed inspection and payment-service charges. It is not an actual quote or a landed-cost total. If courier cost is unknown, record only USD 200.00 of known charges and keep the complete payable scope pending. Do not silently replace missing freight with zero. Keep a possible future credit separate until its conditions are met and confirmed.
6. Keep a confirmation record another buyer can review
The buying owner fills this from the current specification, supplier offer, correspondence and shipping arrangement. Technical colleagues confirm the deliverable; an authorised person confirms charges and credits. The output is a reviewable prepayment record. These are manual fields to copy into your own file, not a form submitted through this site:
- Sample identity
- Parties, project, sample type, model/revision, quantity and unit
- Work scope
- Deliverable, inclusions, exclusions, revision allowance and open inputs
- Charges
- Currency, unit amounts, one-time items, packing and transport; distinguish unknown, confirmed zero and not applicable
- Triggers
- Approver, funds check, preparation start conditions and estimated dates/time zone
- Credit or refund terms
- Type, qualifying order and deadline, amount/items, confirmer and evidence
- Version and next review
- Current agreed record, unresolved-question owner and change trigger
A complete file does not prove supplier identity, bank-account authenticity, compliance or the existence of an order. Use the separate account-change verification process if payment instructions change.
7. Reopen the affected terms when facts change
A revised drawing can change preparation work; a different quantity can change unit pricing; a new delivery address can change packaging or shipping. When a later order meets a claimed credit condition, reconcile that condition and the actual adjustment document rather than treating the original promise as an adjustment already made.
Retain the old version, the reason for the change and both parties’ new confirmations. Then pass the approved sample scope into shipment preparation and evaluation. Overseas buyers can compare like-for-like paid sample offers and avoid mistaking a sample unit price for the complete acquisition cost.
Evidence boundaries and review
Sources checked on 15 October 2026: ITA: Pro Forma Invoice and ITA: Determine Total Export Price. They support broad quotation and cost-scope principles. The seven checks and sample arithmetic are our method. Actual prices, product suitability, taxes, refund rights and delivery results remain dependent on the transaction evidence. Review when the product, charge or credit arrangement changes; a source recheck alone does not create a new publication date.
Frequently asked questions
Does a sample charge always include shipping?
No universal inclusion should be assumed. Confirm packaging, route, paying party and unresolved charges for this particular offer.
Can I deduct a future sample credit from the payment now?
Keep it separate unless the relevant parties have explicitly agreed the current deduction. Record the qualifying order, deadline and adjustment evidence.
Does paying for samples approve the supplier or product?
No. Payment and a complete confirmation record do not replace supplier checks, sample evaluation or product-compliance evidence.
