CN23

CN23 is a customs declaration form used in international postal shipments to declare the contents, value, and other details of goods for customs clearance. It is part of the Universal Postal Union (UPU) documentation framework that accompanies cross-border mail and parcels.

The form is typically used for shipments that require more detailed information than the smaller CN22 declaration. It is commonly applied to commercial goods, higher-value items, or shipments that need explicit tariff classification. The CN23 is usually placed inside the parcel, while a outside label or accompanying documents identify the shipment for customs processing. In some routes, the declaration data may be transmitted electronically to customs through national or carrier systems.

A CN23 entry packet typically includes fields for sender and recipient addresses, a thorough itemized description of contents, quantity, weight, and declared value, country of origin, and the HS tariff code or other classification. The sender must sign a declaration stating that the information is accurate and that the goods are not prohibited or restricted. This information enables customs authorities to determine duties and taxes and to apply any applicable import controls.

CN23 and CN22 are related forms used in postal shipments; CN22 is a shorter declaration suitable for smaller or lower-value items, while CN23 provides more space and detail. Both forms support compliance with international postal and customs regulations, though electronic declarations are increasingly used in some countries.
