Target Audience: Non-EU e-commerce brands, logistics managers, and export coordinators shipping to the European Union
Introduction
Your shipment is packed. Your carrier is booked. Your customer is waiting.
Then customs stops everything.
The commercial invoice is incomplete or incorrect, and your goods sit at the border for days. It is one of the most common reasons for customs holds, and almost always preventable.
The commercial invoice is one of the most important documents for EU customs clearance. It is the record of the transaction between you and your customer, and it must accompany every commercial shipment entering the EU. Without it, your goods do not move.
This guide explains what information is typically required on your commercial invoice, what the common mistakes are, and how to get it right every time.
What Is a Commercial Invoice and Why Is It Required?
A commercial invoice is a document that records the transaction between the exporter (you) and the importer (your customer). It serves as the basis for customs clearance, duty assessment, and VAT collection.
Every commercial shipment from a non-EU country into the European Union must be accompanied by a commercial invoice or, where appropriate, a pro forma invoice.
Unlike a standard sales invoice, the commercial invoice includes specific information required by customs authorities. No specific form is required, but the content must meet EU requirements.
Commercial Invoice vs Pro Forma Invoice
Many shippers confuse these two documents. They serve different purposes.
Commercial Invoice | Pro Forma Invoice | |
Purpose | Records an actual commercial sale | Estimates value for non-commercial shipments |
Used for customs | Yes | Yes |
Reflects | Actual transaction value | Estimated value |
Used for accounting | Yes | No |
When to use a pro forma invoice:
- Samples (with no commercial value)
- Gifts
- Warranty replacements
- Certain returned goods (depending on the customs procedure)
- Items sent for repair or exhibition
Important: Customs will treat the pro forma invoice as the basis for duty assessment if no commercial invoice is provided.
Key Information Required on Commercial Invoices
The information required on a commercial invoice is derived from EU customs legislation and carrier requirements. Based on EU customs regulations and carrier requirements, a compliant commercial invoice should include:
Exporter and Importer Information
Full names and complete addresses of both the seller (exporter) and the buyer (importer). For shipments to businesses, include the recipient’s EORI number where required by the customs process or carrier.
Date of Issue
The date the invoice was created. This helps customs determine the applicable exchange rates and regulations.
Invoice Number
A unique reference number for the transaction. Sequential numbering helps with audits and tracking.
Description of Goods
A full, detailed description of the goods being shipped. This includes the name, material, quality, and intended use. Vague descriptions like “electronics” or “spare parts” are no longer sufficient. Customs authorities and carriers expect sufficiently detailed product descriptions because these are reflected in the electronic pre-arrival customs data submitted under ICS2 (Import Control System 2).
Quantity and Unit of Measure
The number of items and the unit of measure. For EU shipments, you must use standard metric units (such as kilograms, litres, or grams) or standard commercial units (such as pieces, packs, or pairs). Non-metric units like pounds, ounces, feet, or informal measurements are not accepted by EU customs.
Unit Value and Total Item Value
The price per unit and the total value for each item line. This must reflect the actual transaction value.
Total Invoice Value and Currency
The total value of the entire shipment and the currency in which payment is made. You must use the actual currency of the transaction (for example USD, VND, or CNY). EU customs accepts any officially recognized national currency and will convert the amount to Euros using their official monthly exchange rates to determine duties and taxes.
Terms of Delivery (Incoterm)
The Incoterms 2020 rule that governs the transaction (e.g., DDP, DAP, FOB). This determines who is responsible for customs clearance and duties.
Harmonized System (HS) Codes
A minimum of six-digit HS codes for each item line. EU customs use at least the six-digit HS code, while carriers or customs declarations may require additional digits under the Combined Nomenclature (CN) or TARIC. Each distinct item requires its own HS code.
Country of Origin
Where the goods were legally manufactured or underwent their last substantial transformation. If your product is made of components from multiple countries, the country of origin is determined by where the final, essential manufacturing step took place that changed the nature of the product. Simply packaging, sorting, or performing basic assembly of foreign parts in a country does not change the origin. Generic references such as EU are insufficient.
Additional Critical Elements
Beyond the core fields, several additional elements are increasingly mandatory or strongly recommended:
EORI Number
Where the importer is an EU business acting as the Importer of Record, including the EORI number is strongly recommended and may be required by the customs process or carrier.
IOSS Number
For B2C shipments under €150 where VAT is collected via IOSS, the IOSS number must appear on the invoice.
Insider Tip: Ensure the IOSS number is transmitted digitally to your carrier. Never print the actual IOSS number visibly on the outside of the shipping label, as this exposes your number to fraudulent theft and misuse.
Preferential Origin Statement
If goods qualify for lower duties under an EU trade agreement, include a preferential origin statement on the invoice. This can significantly reduce duty costs for the importer.
5 Common Commercial Invoice Mistakes
Mistake 1: Vague Goods Descriptions
Generic descriptions like “electronics,” “apparel,” or “spare parts” are no longer acceptable under the EU’s strict ICS2 protocols.
Consequence: Customs flags the shipment for manual inspection or outright rejection.
Mistake 2: Missing or Shared HS Codes
Every distinct item line requires its own specific HS code (minimum 6 digits). You cannot blanket-code different products under one generic number.
Consequence: Customs delays, miscalculated duties, and potential fines.
Mistake 3: Incorrect or Missing EORI Number
If shipping B2B to a registered business in the EU, the recipient’s EORI number is often required. Remember: a UK EORI (GB prefix) is completely invalid in the EU post-Brexit.
Consequence: The shipment is held at the border until the correct number is provided.
Mistake 4: No IOSS Number for B2C Shipments
For B2C shipments under €150 using IOSS, the IOSS number must be provided digitally.
Consequence: Your customer faces unexpected double-VAT charges and steep carrier handling fees at their doorstep.
Mistake 5: Generic Country of Origin
Writing “EU” or leaving it blank is insufficient. The country of origin must be highly specific (e.g., “China,” “Vietnam,” or “Germany”).
Consequence: Incorrect duty assessment and potential customs penalties.
Language and Format Requirements
The commercial invoice may be prepared in any language. Most carriers accept commercial invoices in English. Customs authorities may request a translation if necessary.
Practical considerations:
- Most carriers now prefer and accept electronic commercial invoices submitted before shipment.
- Many carriers still recommend including a physical printed copy attached to the parcel, although digital flows are dominant.
- Signatures are not legally required by modern EU customs for standard electronic clearance, but they remain a common best practice.
Document Requirement Checklist
Shipment Type | Document Required |
Commercial sale | Commercial invoice |
Samples | Pro forma invoice |
Gifts | Pro forma invoice |
Warranty replacements | Usually pro forma invoice |
Returned goods | Depends on customs procedure |
Personal belongings | Different specific rules apply |
