WHY USE THESE TOOLS
Knowing your import duty and VAT liability before your goods arrive helps you budget your landed cost accurately. Our import duty calculator gives you an indicative figure based on your commodity code, customs value and country of origin.
Choosing the wrong container type wastes money and delays your shipment. Our container sizes guide shows internal dimensions and maximum payload for every standard container type so you can confirm the right fit before enquiring.
IMPORTANT NOTE
The freight calculators and shipping tools on this page provide indicative estimates based on the inputs you provide. They are designed to help you plan and budget, not to replace a formal quotation from our Portishead team.
Actual import duty rates depend on the precise commodity code of your goods, the declared customs value, the country of origin and any applicable trade policy measures. Actual freight rates depend on current market conditions, sailing schedules, chargeable weight and applicable surcharges.



MOST USED TOOL
Our UK import duty calculator is the most used freight tool on this site. Enter your commodity code, the customs value of your goods and the country of origin to get an indicative UK import duty and import VAT figure before your goods arrive.
UK import duty rates are determined by the commodity code of your goods under the UK Global Tariff. Import VAT at 20% is charged on the customs value of your goods plus the applicable duty. UK VAT-registered businesses can use postponed VAT accounting to defer import VAT to their VAT return rather than paying at the point of importation.

The import duty calculator covers all major import origins including China, the USA, India, the UAE and Europe. The air vs sea freight calculator covers the primary trade lanes served by Plexus Freight. The container sizes guide applies to standard container types regardless of origin or destination.
Our container sizes guide shows the internal dimensions and maximum payload for every standard container type including 20ft, 40ft and 45ft units. If your cargo is out of gauge or does not fit a standard container, contact our Portishead team directly before submitting a standard quote request.
Not always. For small, high-value consignments under 500 kg, air freight can be cost-competitive when transit time is a priority and sea freight transit is too slow. Our air vs sea freight calculator shows a side-by-side cost and transit time comparison based on your actual cargo details so you can make an informed decision.
