Meta Description
Material quality disputes in international imports should be handled through defined inspection criteria, batch traceability and contractual remedies. For synthetic leather, coated fabrics and nonwoven materials, buyers should document defects by container, batch and roll number before production use.
Inspect Material Immediately After Container Arrival
Before releasing imported material to production, record:
- Container and seal number
- Roll and batch numbers
- Usable width and thickness
- Surface defects and colour variation
- Packaging or moisture damage
- Quantity inspected and quantity affected
For larger shipments, use an agreed sampling plan such as ISO 2859-1 where applicable.
Document Defects by Roll Number
A claim should contain measurable evidence rather than general descriptions.
| Claim Information | Example |
|---|---|
| Shipment | Container No. / PO No. |
| Batch | Production batch |
| Roll | R021–R028 |
| Defect | Surface delamination |
| Affected quantity | 14.6 m |
| Defect rate | 16% of inspected quantity |
| Evidence | Photos + physical samples |
| Reference | Approved Golden Sample |
This allows the supplier to trace the problem back to a specific production batch.
Compare the Shipment Against the Approved Specification
The buyer should compare actual results with the agreed technical specification.
| Parameter | Contract Requirement | Actual Result | Status |
|---|
| Thickness | 0.80 ± 0.05 mm | 0.91 mm | Non-conforming |
| Width | ≥1,400 mm | 1,397 mm | Review |
| Peel strength | ≥10 N/25 mm | 13.2 N/25 mm | Conforming |
| Colour | Approved sample | Outside tolerance | Non-conforming |
Where visual inspection is insufficient, an agreed third-party laboratory can be used.
Define Replacement or Credit-Note Terms
The purchase contract should establish the available remedies before shipment.
- Replacement shipment for confirmed unusable material
- Credit note where material remains partially usable
- Sorting/rework where commercially practical
- Freight responsibility for replacement goods
- Claim notification period after delivery
The remedy should be based on documented non-conformity and the agreed commercial terms.
💡 Sourcing Tip for Bulk Buyers
Before placing a bulk order, define the inspection method, defect tolerance, sampling level, claim period and replacement/credit procedure in writing.

Solamni Buyer Guarantee
A controlled quality process should cover four stages:
Approved Sample → Production Batch → Pre-Shipment Inspection → Arrival Inspection
For every claim, the recommended traceability chain is:
PO → Container → Batch → Roll → Defect → Affected Quantity
This gives purchasing teams a documented basis for supplier investigation, corrective action and commercial resolution.
B2B Supplier Claims Process
- Quarantine affected material.
- Identify batch and roll numbers.
- Photograph and retain defect samples.
- Calculate the affected quantity and defect percentage.
- Compare results with the approved specification.
- Submit the formal claim.
- Confirm replacement, credit or other agreed remedy.
- Close the claim with corrective-action records.
The objective is straightforward: make conformity measurable, defects traceable and remedies executable.
