Every importer eventually opens a carton that is not what the packing list promised: a lamp for the wrong generation, a fender with a bent edge, a carton two pieces short, or a panel that fits everywhere except the last clip. What happens next decides whether the problem costs one part or one customer relationship.
This is the playbook we would follow on the buying side — and the process we run when a claim comes to us. It is drawn from published terms: the 30-day reporting window, the inspection and packing records we keep, and the resolution categories we work with.
1. Classify the problem before you write the email
Claims move faster when raised in the right category, because each one has a different evidence standard and a different party responsible for the fix.
| Category | What it usually is | Who investigates |
|---|---|---|
| Wrong fitment | Correct part number on the label, wrong generation or side for the vehicle | You and the supplier — against the approved fitment data |
| Manufacturing defect | A fault in material, assembly or finish that is there before packing | Supplier QC, against the golden sample and inspection record |
| Transit damage | Crushing, water ingress, broken lens or bent panel after the container was sealed | Carrier, cargo insurer and packing record |
| Shortage or mismatch | Carton count short, or contents not matching the packing list | Supplier, against loading photos and packing list |
Do not merge categories in one message. A transit-damage claim filed as a manufacturing defect delays both investigations, and an insurer will ask for the carrier claim reference.
2. Build the evidence pack first
The evidence pack is what makes a claim fast. Photograph and record before anything is disposed of, repacked or fitted:
- The sealed container or trailer before opening, and the carton stack as found.
- Carton count against the packing list, including carton numbers and damaged cartons at each layer.
- The label on the affected cartons — SKU, side, quantity and carton number, in one readable photo.
- The part itself, full view and close-up of the fault, with a rule for scale.
- Fitment evidence for a wrong-fitment claim: the part offered up to the vehicle, the mounting points, the connector, and the old part’s label or the VIN plate.
- The packing record — inner packing, foam and how the carton was closed on arrival.
One message with twenty labelled photos resolves more than a week of email. We keep a golden sample and the inspection record for each production batch so a claim can be compared against what was approved.
3. The 30-day window and batch traceability
Claims are accepted within 30 days of arrival with photos, carton labels and the affected quantity. That is not a courtesy deadline — it is how long the evidence is still reliable. After 30 days it becomes difficult to separate a manufacturing defect from installation damage, storage conditions or a part that was fitted and removed.
Traceability runs through the carton number. Every shipment has a pre-shipment inspection report with photos of packed cartons and the sealed container, and the packing record links carton numbers to SKUs and quantities. If you quarantine a suspect carton instead of fitting it, note the carton number first; it is the fastest route to the batch record.
4. What a resolution can look like
Four outcomes are realistic, and it helps to know which one you are asking for before the first message:
- Replacement — the standard outcome for verified manufacturing defects and verified wrong-part shipments, subject to stock and the next production slot.
- Credit — used when the part is usable at a discount, or when the buyer prefers to source the replacement locally.
- Repair contribution — for panels and bumpers a body shop can correct locally faster than a replacement can ship; agree the amount in writing first.
- Corrective action — for a defect affecting a whole batch: containment of unsold stock, a root-cause note and a process change before the next order.
Transit damage is different: the fix usually comes from the carrier or cargo insurer, and the packing record is your supporting evidence. A supplier can improve packing, but that does not replace a damage claim against the party that carried the cargo.
5. Write the claim in one message
A claim that gets an answer in one reply looks like this:
| Field | What to include |
|---|---|
| Reference | Order, invoice and bill of lading numbers |
| Carton | Carton number(s), quantity affected, total cartons received |
| SKU | Part number and the label photo |
| Category | Wrong fitment / defect / transit damage / shortage |
| Evidence | Photo set and vehicle details for fitment claims |
| Requested resolution | Replacement, credit or repair contribution |
| Impact | Is the part blocking a repair order or a retail listing? |
The last field matters commercially. A part blocking a workshop bay gets handled before a part sitting in warehouse stock, and it is fair to say so.
6. Prevent the next claim
Claims are cheaper to prevent than to win. Five controls do most of the work:
- Approve the sample in writing — photos, date and the exact SKU, not just “looks good”.
- Agree the packing specification — foam, film, corner protection, maximum stack height and carton marks for fragile lines.
- Get loading photos — empty container, half-loaded, full, sealed. They settle shortage and damage questions later.
- Confirm fitment data before production — generation, drive configuration and side for every handed part.
- Match the freight mode to fragility — sealed full containers for lamps and painted parts where volume allows; LCL for dense, robust parts.
The quality page describes the inspection flow and records kept per shipment, and the FAQ covers the standard warranty position per family. For the repair-side parts list most claims involve, the collision repair checklist is a useful cross-check.
7. Keep a claims log
A simple log turns recurring claims into a sourcing decision. Track: date, order, SKU, category, quantity, evidence sent, requested resolution, agreed resolution, root cause and the action taken. After two or three entries, patterns appear — a carton type, a carrier leg, a generation, or a fitment sheet that needs correcting.
Share the log with your account manager before the next order. A supplier who can see the pattern will change the packing spec or the label rather than argue about the same part twice.
What to expect from us
Send the claim with the evidence pack to your account manager. We investigate against the golden sample and the inspection record and reply within 5 working days with a resolution: replacement, credit or a corrective action plan. Verified defects are replaced or credited. If the answer is “not a defect”, we show the evidence and the fitment or inspection record rather than simply closing the ticket.
If you are planning an order and want quality and shipping controls agreed before production, send the part list or read the export process guide. Getting the packing spec and fitment data right in the quotation is the cheapest warranty you will ever buy.
FAQ
How should I classify a problem when stock arrives? Separate wrong fitment, manufacturing defect, transit damage and shortage. Each needs different evidence: the fitment claim needs the vehicle and part number, the defect needs function photos, damage needs carton and loading photos, and shortage needs the packing list and count.
What evidence pack should I send? Photos of the part, the carton label and the affected quantity, plus the order or invoice number, the inspection record and, for fitment claims, the VIN and a photo of the installed position. The clearer the pack, the faster the supplier can decide without a back-and-forth.
What timeline is normal for a claim? Report within 30 days of arrival and expect a reply within about five working days once the evidence is complete. A fair process ends in replacement, credit or a corrective action plan, and the outcome should refer back to the approved sample and the inspection record.
How do I prevent the same claim next time? Feed the cause back into the order: confirm fitment in writing, approve a production sample, tighten the inspection checks that missed the issue, and record the correction in the next purchase order. A claim closed without a process change tends to repeat.
