Site standards

Editorial and corrections policy

Public pages must solve a defined import question, disclose their assumptions and link to the authorities needed to check the answer.

Policy effective 5 August 2026.

Publication standard

An indexable guide is published only when it contains a direct answer, a distinct explanation, material caveats and relevant official sources. A database row count or a unique combination of product and country is not enough to justify a public page.

Programmatic tools can help assemble data and identify candidate topics. Candidate pages stay outside the deployed HTML site until they are deliberately selected. Published guides carry a source-check date and are maintained as a small reviewed collection.

Source hierarchy

  1. Current customs, tax and trade authorities for the relevant jurisdiction.
  2. Official international organisations for common frameworks and reference tariff data.
  3. Secondary professional references only for cross-checking or finding a primary source.

The guide links to the primary source wherever a stable public URL exists. Calculator fallback data is labelled and cannot be presented as a confirmed national product rate.

Review and change control

Reviews check that links resolve, time-sensitive claims remain current, examples label hypothetical rates, and limitations still match calculator coverage. A changed date indicates that the page or its cited sources were checked; it is not a guarantee that every tariff row in the underlying database changed on that date.

No advertiser or affiliate may select a tariff result, suppress a caveat or receive favourable source placement. Commercial content, if introduced, must be identified.

Corrections

Send suspected errors to contact@importchecker.net. Include the page URL, product or code, destination, origin, input values and a supporting official source. Reproducible source and calculation errors are prioritised because they can affect both the calculator and explanatory content.

A correction can change text, source mappings, imported data or calculator logic. Material corrections update the affected page’s review date. ImportChecker does not remove a correct caveat simply because it makes an estimate less commercially attractive.
