Tier 1

Primary authoritative

The customs or tax authority, or the legally authoritative tariff dataset.

Tier 2

Official supporting

Official secondary services and explanatory publications of the same governments.

Tier 3

Validation

Cross-country official databases used only to detect discrepancies.

Tier 4

Licensed

Commercial providers, only where no official machine-readable source exists and the licence permits our use. None in use.

CBP publishes these only as bulletins/PDF notices; LandedGrid holds no machine-readable official feed, so non-USD amounts need a rate supplied by you and are labelled USER_PROVIDED.
