Origin documents: CO, EUR.1 and KVK export documents

If your business exports goods to countries outside the European Union, you'll soon be dealing with customs and a pile of paperwork. One of the most important parts of trading internationally is proving where your goods come from. Countries want to know exactly where your products were made, so they can decide whether import restrictions apply and which import duties are due. In this guide we explain exactly which origin documents you need, the difference between a CO and an EUR.1, and how to streamline your international logistics.

What is the origin of goods and why does it matter so much?

The origin of goods is the country where a product was grown or produced, or where it last underwent substantial processing. That's not always the country you send the parcel from.

For B2B shipments outside the EU, proving origin is essential, because it determines:

  • Import duties and levies: many countries have trade agreements. With the right document, your customer pays less (or no) import duty.

  • Trade policy measures: think of import quotas, anti-dumping duties or boycotts.

The Certificate of Origin (CO) explained

A Certificate of Origin (CO, in Dutch) is an official document that proves where your goods come from. Countries in the Middle East, Asia and parts of South America often ask for one. Without it, you risk your business shipment not making it across the border, or customs holding it.

An important detail: a CO doesn't give your customer any reduction on import duties. It serves purely as proof for the import rules of the destination country.

The EUR.1 certificate: save on import duties

Unlike the CO, the EUR.1 certificate (in Dutch) does bring a big financial advantage. The EU has trade agreements with various countries (such as Switzerland, Norway, and countries in Africa and South America).

If your products have preferential EU origin and you add an EUR.1 certificate to your export shipment, the recipient can benefit from reduced import duties or even a full exemption. That instantly makes your products a lot more competitive on the international market.

Arranging KVK export documents: how does it work?

Both the CO and the EUR.1 certificate are KVK export documents. You can't simply print them yourself: they have to be officially issued and stamped by the Kamer van Koophandel (the Dutch Chamber of Commerce).

To get them, you supply the KVK with evidence of where the goods come from (such as a supplier's declaration or a production overview). For the latest guidelines and the application process, see the official documentation from the Kamer van Koophandel (KVK).

Frequently asked questions

What is the difference between a CO and an EUR.1 certificate?+
A Certificate of Origin (CO) only proves which country a product was made in and is used to meet local import requirements. An EUR.1 certificate is used specifically for countries the EU has a trade agreement with, and entitles the recipient to reduced or zero import duties.
Is an origin document always required when exporting outside the EU?+
No, not always. It depends on the destination country, the type of goods and the value of the shipment. Always check the specific customs requirements of the country you're exporting to.
How do I apply for KVK export documents?+
You apply for these documents online, through an intermediary or directly with the Kamer van Koophandel. You always need to be able to prove the origin of the goods with supplier's declarations or proof of production.
Can I use an EUR.1 certificate for shipments to the United States?+
No. The European Union currently has no preferential trade agreement with the United States under which the EUR.1 certificate is used. Regular import duties apply there, based on your product's HS code.
Does ParcelParcel help with drawing up these customs documents?+
