UK landed cost calculator — duty, VAT and shipping, properly sourced.

Every duty rate, VAT rate and shipping figure is sourced from authoritative public data — HMRC's UK Trade Tariff, the EU TARIC database, the US HTS at USITC, Australia's ABF tariff, and Royal Mail's international rate cards. Each result shows the source URL and the date the rate was last verified. Where there's uncertainty (e.g. the current US reciprocal tariff position), we flag it in the warnings.

MFN (Most-Favoured-Nation) is the default WTO rate countries apply to all imports. Preferential rates are lower rates available under a trade agreement (e.g. the UK-EU TCA, UK-Australia FTA) — but only if you meet rules of origin, typically that the goods have at least 50% UK value-add or were substantially transformed in the UK. With the toggle on we apply the preferential rate; uncheck it to see the worst-case MFN scenario.

Following the US Economic Prosperity Deal framework in 2025, UK-origin goods carry a baseline reciprocal tariff (currently around 10%) on top of MFN rates. This is volatile policy — verify the current rate at the USTR before quoting customers. We show it as a separate line so you can see exactly what's been applied.

US states levy sales tax (0–10%) but UK sellers without US nexus typically aren't obligated to collect it — it falls on the buyer as use tax in theory. We don't include it in the calculator; if you sell substantial volume to a single state and may have triggered economic nexus, you should review with a US tax specialist.

Use the UK Trade Tariff lookup at gov.uk/trade-tariff. Small misclassifications can mean meaningful duty differences. If you're shipping to multiple countries, the 6-digit HS code is internationally harmonised — destination-specific 8–10 digit codes may vary slightly. We're building an HS code suggester for ecommerce products — get in touch if you'd like early access.
