A FOB price does not include international freight or insurance. The purchase price is not automatically the customs value; LandedGrid adjusts it to the destination’s valuation basis.

Customs valuation

CIF-type basis — transport and insurance to the border are included

Transaction value (Method 1): the price paid or payable, adjusted to include transport, insurance, loading and handling costs up to the place of introduction into the UK, plus statutory additions.

Taxation (Cross-border Trade) Act 2018, s.16; Customs (Import Duty) (EU Exit) Regulations 2018 · HM Revenue & Customs

Customs exchange rate

HMRC publishes monthly customs exchange rates (currency units per £1) that must be used to convert foreign-currency values for customs duty and import VAT. LandedGrid ingests the official monthly file and applies the rate for the calendar month of the calculation date.

Applicable date: Calendar month of the declaration (HMRC monthly period rate).

Taxes and government fees on import

  • Import VATnot machine-calculable

    Base: customs value + duty + additional duties + trade remedies + excise + inland freight to destination

    Value Added Tax Act 1994, s.21

Low-value consignments

  • Consignments valued at £135 or less: VAT is charged by the seller (or online marketplace) at the point of sale rather than at the border, and customs duty is not charged. The £135 limit applies to the value of the total consignment, not to individual items.

What the origin — United States — changes

The standard (MFN / third-country) rate applies to goods from United States unless a measure for that origin says otherwise. Three kinds of measure depend on origin, and the calculator above resolves each for your tariff code and date:

  • Preferences. Where United Kingdom grants a preferential rate to United States under a trade agreement or scheme, it is shown as a separate scenario. It applies only if the goods meet the rules of origin and you hold proof. How preferential origin works.
  • Trade remedies. Anti-dumping and countervailing measures aimed at United States are held in the tariff data and are surfaced with their producer-specific conditions. About trade remedies.
  • Additional tariffs. Origin-based additional duties in the tariff are applied automatically.

What LandedGrid does not calculate for this destination

  • quotas: First-come-first-served quota balances are checked per request with a 24-hour cache. Licence-managed or unavailable balances remain unresolved; in-quota rates are conditional on allocation.
  • excise: Excise duty measures are read from the UK Trade Tariff where present; rates that depend on alcoholic strength or product composition are flagged for review rather than calculated.
  • regulatory: Import control measures attached to the commodity in the UK Trade Tariff are listed. Product safety, labelling and sector rules outside the tariff are not covered.
  • Northern Ireland (Windsor Framework) movements are not modelled; results are for Great Britain imports.
  • Import VAT rate is read per commodity from the HMRC Trade Tariff API at calculation time and cached for 24 hours.
