When bulk goods don’t match the approved sample, your next move depends on how well you documented the approval.
A bulk order that differs from the sample is one of the most common quality problems in importing from China. It is not always the result of deliberate deception — production batches vary, raw materials change, and factory quality control is not always consistent. But the outcome is the same: goods that do not match what you approved.
How well you can resolve the situation depends almost entirely on what you documented when the sample was approved. A supplier who can point to written specifications, a QC checklist, and approved sample photos is much easier to hold accountable than one who only received a verbal “looks good.”
The same process applies whether you discover the mismatch during a pre-shipment inspection, at a China warehouse, or after goods arrive at your destination. The earlier you find it, the more leverage you usually have.

What Counts as a Bulk-vs-Sample Mismatch?
Not every difference between sample and bulk goods is a dispute. Some variation is expected. But the following differences typically count as a meaningful mismatch:
- Material — feels different, lighter, thinner, or lower quality than the sample
- Color or finish — noticeably different color, texture, or surface treatment
- Dimensions — outside the agreed tolerance range
- Weight — significantly lighter or heavier than the sample
- Functionality — does not perform as the sample did
- Packaging — different box, bag, or protective material than what was approved
- Labeling — wrong label, missing barcode, incorrect language or content
- Workmanship — lower assembly quality, more visible defects, rougher edges or seams
- Accessories or components — missing items that were included in the sample
If you have a written QC checklist or specification sheet, compare the goods against that. If you only have the sample itself or approval photos, use those as your reference. The clearer your baseline, the stronger your position.
First Step: Document and Compare
Before you contact the supplier, before you use the goods, and before you make any decisions — document everything.
Photograph and video the unboxing
Record the process of opening the shipment. This establishes that the problem was present when goods arrived, not afterward.
Compare against your golden sample
If you kept a sealed golden sample — an approved unit stored specifically for reference — compare the bulk goods directly against it. This is the clearest possible evidence of a mismatch.
Take side-by-side comparison photos
Place bulk goods next to the approved sample and photograph them together. These comparison photos are the single most useful piece of evidence in a bulk-vs-sample dispute.
Compare against your approved sample record
If you kept approved sample photos from multiple angles, use them as a direct reference. This is why sample approval documentation matters.
Compare against written specifications or QC checklist
If you have a specification sheet or QC checklist, go through it item by item and note every deviation.
Do not use, sell, relabel, or discard the goods before documenting
Once goods are used or altered, your evidence becomes much weaker. Even if the problem is obvious, preserve the evidence first.
Classify the Severity
Once you have documented the mismatch, assess how serious it is. This is a practical decision framework — not a formal inspection standard. The same issue may be minor for one product and major for another, depending on customer expectations, safety requirements, and sales channel standards.
Minor mismatch
The product differs slightly from the approved sample but is still usable and saleable. Examples: color is slightly darker than expected, weight is at the outer edge of the tolerance range, packaging is slightly different but functional.
Typical response: Document the issue, ask the supplier for a credit, discount, or improvement on the next order.
Major mismatch
The product differs in a way that meaningfully affects function, appearance, customer experience, or saleability. Examples: material is noticeably different, dimensions are outside agreed tolerances, finish quality is significantly lower than the sample.
Typical response: Request replacement units, partial refund, rework, or hold the final payment balance while the issue is resolved.
Critical mismatch
The product is completely wrong, unsafe, unusable, or illegal to sell. Examples: completely wrong product shipped, product does not function at all, product fails basic safety expectations.
Typical response: Stop the shipment or remove from sale immediately. Escalate using platform protection or payment-provider dispute options.
Message Template: Bulk Goods Do Not Match Approved Sample
Once you have your documentation ready, contact the supplier with a factual, specific issue report.
Hello [Supplier Name],
We received the bulk order for [product name / order reference] on [date].
After comparing the bulk goods with the approved sample dated [sample approval date], we found the following differences:
1. [Difference 1] — Approved sample: [description / standard]; Bulk goods: [actual issue] — see attached photo
2. [Difference 2] — Approved sample: [description / standard]; Bulk goods: [actual issue] — see attached photo
3. [Difference 3] — Approved sample: [description / standard]; Bulk goods: [actual issue] — see attached photo
Attached files:
– Approved sample photos
– Bulk goods photos
– Side-by-side comparison photos
This issue affects [function / appearance / packaging / saleability].
Please confirm how you can help resolve this. We would like to discuss one of the following:
– Replacement units
– Partial refund
– Credit toward the next order
– Rework or correction
Please reply by [date — allow 3–5 business days].
Thank you.
Why this works: The template compares bulk goods directly against the approved sample standard — not just “I am unhappy” but “here is what was agreed and here is what was delivered.” Side-by-side photos make the difference visible and harder to dispute.
Platform Protection and Payment Leverage
If goods are still in China or the final balance has not been released, that is your strongest leverage.
Do not approve shipment or release the remaining payment until the issue is acknowledged and a resolution is agreed in writing. This is why pre-shipment inspection matters — discovering problems while goods are still at the factory gives you maximum leverage to request rework or hold payment.
Alibaba Trade Assurance
If the order was placed and paid through Alibaba Trade Assurance, and specifications and sample approval were documented on-platform, you have grounds to open a dispute. Trade Assurance is most effective when the issue is objective, measurable, and tied to written terms confirmed on-platform.
1688 and agent-managed orders
If you ordered through a sourcing agent, contact them first. They are better positioned to communicate with the supplier and escalate within the platform. The strength of your position depends on how clearly the agent documented the approved sample and specifications with the supplier.
General principle: Platform protection works best when the evidence is documented inside the platform’s system. Off-platform agreements and verbal approvals are much harder to enforce.
What If the Goods Are Already Listed or Sent to Customers?
If you discover the mismatch after goods have already been listed for sale or delivered to customers, the priority is to stop additional harm.
- If the issue affects safety or basic function, stop selling immediately and review your platform’s policies before relisting
- If you cannot separate affected units from unaffected inventory, pause sales until you understand the batch risk
- Separate the affected batch if possible, so you can track which units came from this shipment
- Document any customer complaints or returns related to this shipment — this evidence can support your supplier claim
- Do not blame the supplier publicly in customer-facing communications
- Check your sales platform’s rules before relabeling, repacking, or reselling affected goods
The details depend on your sales channel, the nature of the problem, and platform policies — which change frequently. The general principle is: understand the problem fully before taking further action.
How to Prevent This Next Time
Keep a golden sample
After approving a sample, keep one unit sealed and stored as a reference — the “golden sample.” If a bulk order dispute arises, you have the original approved unit to compare against directly.
Keep an approved sample record
Photograph the approved sample from multiple angles, measure and record key dimensions and weight, and store the record before placing the bulk order.
Confirm specifications in writing
“Bulk goods must match the approved sample” is too vague. Write the measurable specifications into your purchase order — material, dimensions, weight, color reference, packaging, labeling.
Write and share a QC checklist before production
Give the supplier clear standards before bulk production begins. Share the checklist, not just the sample.

Arrange a pre-shipment inspection
A third-party inspection before goods leave China catches mismatches when you still have leverage to fix them.
→ Pre-Shipment Inspection Guide →
Control payment timing
Structure payment so a portion is held until goods are confirmed acceptable. A supplier who has received full payment has little incentive to resolve quality issues quickly.
Common Mistakes
Approving a sample without written specifications
“Approved” without a record of what you approved gives you nothing to reference when bulk goods differ.
Not keeping the approved sample or approval photos
Without a physical sample or photos, you cannot prove what was agreed. Take detailed photos before the sample leaves your hands.
Saying “not the same” without showing side-by-side evidence
Vague complaints are easy to dismiss. Side-by-side comparison photos with specific notes are much harder to ignore.
Not identifying the affected batch
If only part of the shipment is affected, identify carton numbers, lot numbers, production dates, or warehouse locations where possible. This helps you decide whether the issue affects the entire order or only part of it.
Continuing to sell goods before understanding the issue
If you discover a problem, pause before selling more. If the issue affects customers, it affects your seller account too.
Asking for a full refund when a partial remedy is more realistic
Match your request to the scale of the problem. A minor color difference does not justify the same response as a completely wrong product.
Paying the final balance before comparing goods against the sample
Final payment is your strongest leverage point. Confirm the goods are acceptable first.
