Customs Declaration CN22 / CN23
CN22 and CN23 are the customs declarations for postal shipments to non-EU countries. Which form applies when and how to fill it in correctly.

The customs declaration CN22 or CN23 – German: Zollinhaltserklärung – is the standardised customs form of the Universal Postal Union (UPU) for goods sent by post to countries outside the EU. It is attached to the outside of the item and tells customs what is inside, what it is worth – and why it is being sent.
CN22 or CN23 – which form applies?
The CN22 is the compact, sticker-format declaration for items of low value – the threshold is around 300 special drawing rights (SDR), roughly €325–380; since it is defined in SDR, the euro equivalent moves with the exchange rate. Above that – or for certain types of item – the CN23 is required as the detailed multi-copy form, usually together with the dispatch note CP71.
Where do I get the form?
The official form comes from Deutsche Post – it can be downloaded or completed online there. Important: since 2021, the customs data must additionally be transmitted electronically in advance to the destination country. With online franking it is collected automatically; a purely handwritten form without electronic data is no longer sufficient.
Filling it in field by field
- Category of item: tick gift, sale of goods, commercial sample, documents, or returned goods
- Description of contents: precise – not "clothing", but "2 cotton t-shirts"
- Quantity and net weight per line
- Value per line with currency – realistic, never €0
- HS tariff number (the first six digits of the globally harmonised HS code)
- Country of origin of the goods
- Date and signature of the sender
Common mistakes
Three mistakes regularly hold shipments up at customs: a vague description of contents ("gift", "accessories"), a declared value of €0, and a missing signature. The result is returned items or days of delay. And: the customs declaration does not replace an invoice – commercial shipments additionally need a proforma invoice or commercial invoice attached to the outside.
