What we are building
The aim is a fast, ungated tool that combines landed-cost arithmetic with current UK tariff data, while keeping uncertainty and regulatory conditions visible.
Operator
BorderMath is operated by Airborne Media & Consultancy Ltd. It is not affiliated with HM Revenue & Customs or GOV.UK.
Corrections
If you find a broken tariff lookup, misleading explanation or calculation issue, email contact@airbornemedia.co.uk. Regulatory and tariff data corrections should also be checked against the official source.
Publisher & review process
BorderMath is published by Airborne Media & Consultancy Ltd (company number 17415868). The site separates stable arithmetic from changeable tariff assumptions: calculation rules are documented in Methodology, while commodity measures are requested from the official UK tariff service rather than copied into undated rate tables.
Material explanatory changes are reviewed against primary UK government guidance. Route and product guides show a review date and link readers back to the live tariff or the relevant origin guidance. Corrections can be reported to contact@airbornemedia.co.uk.
