CN23 customs forms in Ireland

Let the service determine the form

Do not choose CN22 or CN23 from memory alone. Enter the shipment honestly in the current An Post process and use the documentation it requires for that destination and postal product.

• Classify documents versus goods
• Use the actual value
• Follow the generated label set

Describe every item

Use specific plain-language descriptions and separate materially different contents. State quantity, weight, value and origin as requested instead of writing generic terms such as sample or merchandise.

• Name the product
• Use real quantities
• Keep totals consistent with the parcel

Use correct transaction details

Select sale, gift, returned goods or another category only when it is true and supported by records. A customer order is not a gift, and incorrect status can delay assessment or create liability.

• Keep invoice or order proof
• Declare currency correctly
• Include tariff information when requested

Attach and retain documents

Follow the label instructions so customs documents remain accessible and barcodes stay readable. Keep a copy of the declaration, receipt and value evidence until delivery and any claim period pass.

• Do not cover required documents
• Keep data consistent across invoice and declaration
• Never include prohibited goods

How to get it right

1. Check the route: Confirm the destination and whether the item contains documents or goods.
2. Gather item data: Prepare descriptions, quantities, weights, values, origin and tariff details where required.
3. Complete the official flow: Use the customs declaration produced or required for the selected service.
4. Attach and keep copies: Follow placement instructions and retain shipment and transaction evidence.
