The Importance of Compliant Customs Invoices for Manufacturers exporting and importing.

As a European freight forwarder we spend a fair bit of time reviewing commercial invoices, ensuring customs compliance is adhered to. Despite stressing the importance of this, it is not uncommon to receive non-compliant invoices missing essential information required for accurate export and import declarations. Dont forget - export and import declarations can be audited for up to 5 years after admission, so if you thought you were lucky enough to get away with stating the wrong incoterm, think again. 

In global manufacturing, your product isn’t the only thing crossing borders—your documentation is just as critical. As a manufacturer, ensuring that your customs invoices are compliant can mean the difference between a smooth international delivery and costly delays, penalties, or strained customer relationships. Whether you’re shipping components, finished goods, or custom equipment, a properly prepared customs invoice is essential for international trade compliance. 

To keep up to date with compliance, see our DLS checklist for a compliant commerical invoice: 

To ensure compliance, include the following details:

• Exporter and importer info (name, address, contact, EORI numbers, VAT numbers)

• Accurate product descriptions (be specific—model numbers, materials, use)

• Quantities and unit pricing

• Currency used (USD, EUR, etc.)

• Total value of goods

• Country of origin

• HS code (Harmonized System code)

• Incoterms (e.g., EXW, FOB, CIF)

• Freight, insurance, and other charges, if applicable

• Signature and company stamp, where required

• Prefential origin statment, when applicable

A Word on Product Classification (HS Codes)

As a manufacturer, misclassifying your goods on the invoice can cause major issues. Customs authorities rely heavily on the HS code to determine duty rates and eligibility for trade benefits. Make sure your classification is up-to-date and matches official tariff schedules.

Your job as a manufacturer doesn’t end when the product leaves the warehouse. In international trade, compliance is part of the product. A precise, compliant customs invoice ensures smooth transits, less delays and lower costs.
