Consistency is the whole game
Customs queries are usually triggered by mismatches, not by missing pages. The product description, model number, quantity, value and parties on the commercial invoice, packing list, origin evidence, any permit documents and the carton marks all need to agree. Under-declared values invite reassessment; inconsistent values invite inspection.
Ask for draft documents early. If the descriptions drift between drafts, you have found the problem while it is still free to fix. Our quote cost breakdown shows why a precise specification is also a commercial control.
The core document set
| Document | Who issues it | When it must exist |
|---|---|---|
| Specification and approved sample | Buyer and factory, signed off together | Before the proforma invoice |
| Proforma invoice with Incoterm | Factory / supplier | Before the order is placed |
| Commercial invoice and packing list | Factory / supplier | At shipment, matching carton marks and the sealed sample |
| Bill of lading or air waybill | Carrier / forwarder | On shipment |
| Certificate of origin and supporting declarations | Issuing body and supplier | At shipment, consistent with the invoice |
| Permits, treatment or phytosanitary evidence where required | Appointed body and factory | Before loading, not after arrival |
| Pre-shipment inspection report | Independent inspector | Before loading, against the approved sample |
Language and local schedules
Some island markets require documents, inventories or product labels in French and operate their own tariff and tax schedules. That is a local requirement, not a regional one, and it changes with the product. Put the required language in the purchase order and have your licensed broker confirm the current classification, charges and marking rules before production — not when the container is already booked.
Biosecurity and wood packaging
Wooden pallets and crates generally need the appropriate treatment mark, and plant-based or timber goods may need an import permit or phytosanitary evidence. Containers should be clean and free of soil, seeds and plant residue. Ask your broker which requirements apply to your product and destination, then make the factory responsible for them in the purchase order. Custom packaging guide covers how to specify packing before production.
Ratings, markings and packing
| Check | What to verify |
|---|---|
| Supply and plug | Voltage, frequency and plug type stated in the purchase order and confirmed on the production batch |
| Labels and manuals | Required language, model number, ratings, warnings and country-of-origin marking |
| Model consistency | The model on the label matches the invoice, test evidence and any permit document |
| Packing for the climate | Moisture protection, carton strength, corner protection and palletisation for humid conditions and repeated handling |
