Customs Duty
Duty & Tax Basics · Core Concepts
What is Customs Duty?
Customs duty is a tax a government charges on goods brought into its territory from abroad. It's collected by customs authorities at the border (or, increasingly, at checkout by the seller) and is normally calculated as a percentage of the goods' value, though some countries charge it per unit or per kilogram instead.
The rate that applies depends on what the product is (its tariff classification), where it came from (its country of origin), and whether a trade agreement between the origin and destination countries reduces or removes the standard rate.
Think of customs duty as an entry fee for a product crossing a border, similar to a toll you might pay to drive into a city. The fee is usually a percentage of what the item is worth, and how much you pay depends on what kind of product it is and where it's coming from.
When to Use It
Customs duty applies any time a shipment crosses from one customs territory into another - most commonly when a shopper orders from a store based in a different country or region than where they live. It's separate from any local sales tax or import VAT, which is charged on top of it.
Examples for Customs Duty
| Destination | Typical duty rate | Duty-free threshold |
|---|---|---|
| European Union | 0-16.5%, category-dependent | None below €150 for duty (VAT still applies) - flat €3 IOSS duty since July 2026 |
| United Kingdom | 0-12% (estimate), category-dependent | £135 |
| United States | ~10-12.5% baseline (volatile) | None - eliminated in 2025 |
| China | 13-50% (postal tax bands) | RMB 2,000 per shipment (postal regime) |
Customs duty and import VAT/sales tax are often confused, but they're calculated and applied differently - duty is usually charged first, on the customs value alone, and VAT is then charged on the customs value plus that duty. Assuming a 'duty-free' destination means no charges at all is a common and costly mistake, since VAT frequently still applies even when duty doesn't.
Frequently Asked Questions About Customs Duty
Is customs duty the same as VAT or sales tax?
No. Customs duty is a tariff on the goods themselves, charged once at import. VAT or sales tax is a consumption tax charged on top of the goods’ value plus duty, and applies domestically too - not just to imports.
Who actually pays customs duty?
Whoever is named as the importer of record - usually the buyer for a typical online order, unless the seller has agreed to a delivered-duty-paid arrangement and collects it upfront.
Does customs duty apply to gifts?
Often yes, though many countries offer a lower duty-free allowance specifically for genuine gifts between private individuals - it’s usually smaller than the standard commercial threshold and excludes ordinary online purchases.
