ImportChecker

Import duty calculator

Estimate customs duty, import VAT or GST, and the extra measures currently covered by our data. Start with the product: its classification determines which rate can apply.

What are you importing?

You will need the product, the country you are importing into, where the goods are from, the goods value, and any shipping or insurance costs you want included.

Shipment value

Most duty is a percentage of value. Some products use weight, quantity or volume; those parts are shown as not priced until the required unit can be calculated.

Estimate only. Duty and VAT/GST are calculated where the available rate data supports it; unpriced fees, exemptions, quotas, or eligibility rules can still change the final customs bill.

What the estimate tells you

Customs value
The value used as the starting point for duty. Valuation rules differ by country and transaction.
Customs duty
A percentage or specific charge tied to the product classification, destination and origin.
VAT or GST
Import tax may be charged on customs value plus duty and other costs. Reduced, zero and exempt treatment can apply.
Known gaps
The result identifies components that still need checking, such as brokerage, quotas, excise or product-specific rules.

A simple worked example

Suppose the customs value is £1,100 and the correct duty rate is 5%. Duty would be £55. If UK import VAT applies at 20% to £1,155, the VAT would be £231. The illustrative landed amount is £1,386 before brokerage, clearance fees and any unpriced measures.

This is a method example, not a product rate. A 0%, 5% or 12% duty rate can all be plausible for different products. Search for the product and verify its tariff row.

What you need for a useful estimate

  1. A specific product description, material and intended use.
  2. The importing country and true country of origin.
  3. The price paid, shipping, insurance and the delivery terms.
  4. The quantity or weight if the tariff uses a charge per unit.
  5. Any evidence needed for a preferential origin claim.

Understand the calculation

Use it for planning, not a customs declaration

ImportChecker is an approximate estimator. It does not issue binding classifications or customs rulings. Get help from a broker or customs authority when a shipment is high value, regulated, origin-sensitive or dependent on a quota or exemption.
