Build the customs value, ad valorem duty and import VAT scenario.
Cross-foot the invoice, freight, insurance, adjustments, percentage-based duty and import VAT in one browser-only worksheet. Every rate comes from you. Every formula stays visible.
How do customs value, duty and import VAT connect?
For a transaction-value planning scenario, start with the converted goods price, then add or deduct the amounts you have established for customs value. Apply the ad valorem percentage you have checked. Build the import VAT value by adding duty, other import charges and relevant incidental expenses.

Know what you still need to decide.
01Which exchange rate should I enter?
Enter invoice-currency units per £1. HMRC monthly tables use this direction: if £1 equals 1.1564 euros, enter 1.1564 and the workpaper divides the euro amount by that rate. If the goods amount is already in pounds, enter 1. This workpaper does not choose the applicable rate.
02Where do I find the import duty and VAT rates?
Use the current UK Trade Tariff after the goods, commodity code, origin, date, procedure and applicable measures have been checked. Enter the percentage rates you have established. This workpaper does not perform a tariff lookup.
03Does this workpaper decide which customs valuation method applies?
No. The build-up is useful for a transaction-value planning scenario, but the correct valuation method and the amounts to include or exclude must be established from the facts and current guidance.
04Can I use a preferential or reduced duty rate?
Only enter that rate after eligibility, origin, evidence, quota, suspension, relief and declaration conditions have been checked. The workpaper applies the number you enter and does not test entitlement.
05Does the import VAT result say what can be reclaimed?
No. It is an arithmetic planning amount based on the VAT value and rate entered. VAT accounting, postponement, payment and recovery depend on the importer and transaction facts.
06Does this calculate specific or compound customs duties?
No. This version applies only an ad valorem percentage to customs value. If the tariff measure uses an amount per weight or unit, or combines that amount with a percentage, use the applicable tariff calculation instead of this duty result.
Check the method and rates before the arithmetic.
These current HMRC sources support the valuation sequence and rate checks. They do not turn the workpaper into an HMRC calculation or decide which facts apply to a movement.
