-Traceability: Each coil has unique ID, full batch record & MTC EN 10204 3.1/3.2
Actual Export Cases & Solutions
Case 1: Thickness tolerance complaint (0.1mm out of tolerance)
-Issue: A Southeast Asian buyer received coils with uneven thickness, causing stamping die wear and high scrap rate.
-Our solution:
Upgrade to precision rolling + online thickness gauge (±0.03mm max)
Re-inspect the entire batch; replace out-of-tolerance coils free of charge
Provide SGS thickness report before next shipment
-Result: Zero tolerance issues in subsequent orders; scrap rate dropped from 8% to <1.5%.
Case 2: Surface scratches & rust spots during sea freight
-Issue: Middle East customer found BA/2B surface scratches & slight rust after 30-day sea shipment.
-Our solution:
Apply double-sided PVC/PE film + interleaving paper for bright finishes
Use waterproof paper + steel strapping + fumigated wooden pallets (IPPC)
Add desiccant inside coil package; mark "Keep Dry" in English/Arabic
-Result: No more scratches/rust complaints in 12+ repeat orders.
Case 3: Certificate & customs clearance delay (EU/REACH/RoHS)
-Issue: European buyer needed CE/REACH/RoHS documents but supplier could not provide, leading to port detention & extra cost.
-Our solution:
Provide MTC + CE (EN 10088) + RoHS + REACH SVHC compliance documents
Issue preferential CO / Form A / Form E for tariff reduction
Double-check document consistency before shipment
-Result: Smooth clearance; no detention cost; buyer extended annual contract to 500 MT/year.
Case 4: Wrong grade delivered (201 instead of 304)
-Issue: A South American importer received 201 coil instead of 304, causing corrosion failure in kitchen equipment.
-Our solution:
Full material test (XRF + chemical lab) on every coil before loading
Label each coil with grade / heat No. / batch No. / size in English
Replace wrong batch air freight at our cost + compensate rework loss
-Result: Regained full trust; customer became our top 3 regular buyer.
