In Cambodia’s import and export landscape, accurate and complete shipping documentation is more than just a requirement — it’s the backbone of successful international trade. Whether you're a small business or a seasoned exporter, proper export-import shipping documentation is critical to avoiding costly delays, ensuring smooth customs clearance, and maintaining compliance with evolving import-export customs regulations.

Incomplete or inaccurate shipping documents for imports and exports can halt shipments at the border, leading to lost time, penalties, and reputational damage. Understanding the value of documentation and working with a seasoned logistics supplier like DHL Express may make all the difference for Cambodian companies entering international markets. 

Core shipping documents for imports and exports

Every international shipment — no matter the destination — relies on the accuracy of its shipping documents. From export documentation to import documents, the right paperwork ensures your goods move efficiently through customs clearance procedures in Cambodia and abroad.

Essential documents for export

Essential documents for imports

  • Customs Export Declaration
  • Commercial Invoice for customs
  • Packing List for shipping
  • Road Transport Document (if departing by land)
  • Bill of Lading (if departing by sea)
  • Terminal Handling Receipts (if departing by sea)
  • Insurance Certificate
  • Export Permit
  • Certificate of Origin
  • Customs Import Declaration
  • Commercial Invoice
  • Packing List
  • Road Transport Document (if arriving by land)
  • Bill of Lading (if arriving by sea)
  • Import Permit
  • Insurance Certificate
  • Tax Certificate
  • Certificate of Origin
  • Company Registration

Common customs declaration errors

  • Incomplete or inconsistent information: Errors like typos, wrong Harmonized System (HS) codes, or mismatched values across documents often trigger customs checks. For instance, if the commercial invoice does not match the packing list or certificate of origin, customs may refuse the shipment or charge higher duties.
  • Omitted or incorrect documents: Forgetting a required certificate (e.g., Certificate of Origin) or using an outdated customs form leads to instant rejections. It’s essential to include every mandated form – invoices, packing lists, permits, etc. – for your specific cargo.
  • Regulatory non-compliance: Not securing needed licenses or failing to meet special requirements (like missing a CamControl inspection) can halt goods at the border. Goods must also be correctly classified under Cambodian tariffs; misclassification can incur penalties.

Tip: To avoid these pitfalls, always double-check your export documents and work with a knowledgeable logistics partner like DHL Express. 

Key documents demystified: Commercial invoice and more

Commercial invoice for international shipping

This is the core document for customs. It serves as the bill of sale and contains critical data for calculating duties. A proper invoice must include:

  • Seller and buyer details
  • Accurate description of goods
  • Quantity and unit value
  • Total value
  • HS Codes
  • Incoterms and payment terms

Tip: Use DHL Express’ online shipping tools to generate your invoice. These tools require the necessary fields and prevent missing information. Always review it carefully and sign it before shipment.

Packing list

This lists the contents of the shipment in detail (e.g., item quantities, weights, and packaging dimensions). Customs and freight handlers use it to verify what is in each box or pallet. 

Keep it consistent with the commercial invoice. For example, if the invoice says 100 widgets, the packing list should also account for 100 widgets split into the correct number of cartons with matching weights.

Certificate of Origin (COO)

This certificate confirms where the goods were manufactured. Under trade agreements, such as the ASEAN Trade in Goods Agreement, the COO is often necessary in order to claim lower tariff rates. Cambodian customs will ask for a COO from an authorized body (e.g., Chamber of Commerce) when preferential rates apply.

Other permits and certificates

Even with these basics, many shipments require extra paperwork. For example, Cambodia’s import rules require pre‑clearance certificates for controlled items – food, pharmaceuticals, and electronics need CamControl approval, and plants or animals need special health or phytosanitary certificates. 

Check the official Cambodia National Trade Repository or consult DHL Express to see if your items fall under a regulated category. Arrange these documents in advance to avoid last-minute holds.
