Official source notes and calculator assumptions should be reviewed before shipment, label purchase, invoice filing, or customs entry.

Formula / Criteria

Calculation logic

The generator estimates whether a CN22 or CN23-style declaration is likely based on parcel value and weight, then creates a customs declaration draft.

Example

Scenario

A small parcel with two cotton T-shirts can include item description, HS code, China origin, value, and weight before printing a customs declaration draft.

Source Note

Official check

Verify CN22/CN23 rules with your postal operator and destination customs authority, especially after low-value shipment policy changes.

Limitations

Filing check

This tool provides estimates and document preparation support only. It is not customs, tax, legal, broker, or freight forwarding advice. HS code candidates and duty estimates must be verified with official tariff databases or a licensed customs broker before filing.
