Most customs delays on hair consignments are not caused by the goods. They are caused by paperwork that disagrees with itself. A single mismatched weight or description across two documents is enough to hold a shipment.
1. The Core Document Set
Expect a commercial invoice, packing list, and a certificate of origin, plus the transport document and any applicable declaration of conformity. Each serves a distinct purpose at the border and none substitutes for another.
The packing list is the document inspectors use to locate goods physically. If it lists cartons by number and weight but the commercial invoice lists bundles by SKU, verification becomes slow.
2. Why the Certificate of Origin Matters
Origin documentation supports the declared source of manufacture and underpins any preferential tariff treatment claimed. Without it, an importer may still clear goods but loses the ability to substantiate a reduced rate.
The certificate must describe the goods consistently with the invoice. A generic product description on the certificate and a specific one on the invoice is a common and avoidable discrepancy.
3. The Mismatches That Trigger Queries
Watch for gross versus net weight being transposed between documents, unit counts expressed in strands on one form and grams on another, and inconsistent HS classification across repeat shipments.
Inconsistent classification is the most expensive because it invites post-clearance review. Decide the heading once, document the rationale, and apply it to every shipment thereafter.
4. Building the Checklist Into Your PO
Put the required document set into the purchase order rather than requesting it after production. Specify the description, unit basis, weight basis and HS code the documents must carry, and require scans before departure.
Pre-departure document review costs minutes. A held consignment costs demurrage, storage and client goodwill.
