Import Documentation Checklist for Cambodian Customs

Why the paperwork decides the timeline

Duty is a calculation; clearance is a document check. A shipment with perfect documents can clear in a day, while a shipment missing one certificate can sit for a week accruing storage and demurrage. Build the file before the goods move, not after they arrive.

Commercial documents

• Commercial invoice — seller, buyer, description, quantity, unit price, currency and the agreed trade term.
• Packing list — cartons, dimensions, weights and marks, matching the invoice line for line.
• Sales contract or purchase order, where customs asks to see the underlying transaction.

Descriptions matter. "Spare parts" or "samples" invites questions; a specific description with material and function speeds the classification and reduces the chance of a re-assessment.

Transport documents

• Bill of lading for sea freight, or airway bill for air freight.
• Arrival notice from the carrier or agent.
• Freight and insurance evidence if the invoice is not on a CIF basis, since customs needs to establish the CIF value.

Permits and certificates

The permit list depends on the product. Common categories that require additional approval include food and beverages, pharmaceuticals and medical devices, agricultural inputs, telecommunications equipment, chemicals and second-hand machinery. Where a permit is required, it is required before release — not after.

Ask your supplier early whether the product needs a certificate of conformity, a health certificate, or an import licence, and who is expected to obtain it.

Certificates of origin

A certificate of origin does not change the duty you pay on a normal import, but it matters for goods that may qualify for preferential treatment under a trade agreement, and it matters if you later re-export. Keep the original.

Who lodges the declaration

Declarations are normally lodged electronically by a licensed customs broker on your behalf. The broker is the importer's agent, not the authority's, so choose one who will show you the declaration before it is lodged and explain the classification used.

The gaps that cause most delays

1. Invoice value that does not match the freight or insurance evidence.
2. A description too vague to classify.
3. A required permit discovered at arrival.
4. Packing list weights that disagree with the carrier's figures.

Treat the file as a checklist you complete before booking, and most clearance problems disappear before they start.
