ImportChecker

Public source register

Where the rates come from

ImportChecker combines tariff schedules, VAT or GST tables and selected trade measures. This register links directly to the public authority behind each imported source.

Source links checked 5 August 2026.

How a source is selected

  1. A national or regional tariff line is preferred when it is available for the destination.
  2. A WTO most-favoured-nation row can be used as a labelled fallback when a national row is unavailable.
  3. A broad VAT or GST rate is added only as an estimate. Product-specific reduced, zero and exempt treatment still needs checking.
  4. Preferential rates and extra duties are included only where imported data matches the product, origin and route.

A source being present does not mean every legal condition from that source has been converted into calculator logic. The result labels fallback rows and known gaps.

What is not treated as a final authority

Search snippets, marketplace estimates and generated summaries are not tariff authorities. ImportChecker may use international reference datasets for coverage, but it labels them as fallbacks. The customs authority’s current product row and legal notes take priority over this site.
