How to Calculate Import Duty from China
Four steps to a realistic landed-cost number: find the HS code, set the customs value, apply the duty rate, then add VAT/GST. Here's the method, a worked example, and the errors that quietly blow up your margin.
To calculate import duty from China, find your product's HS code, establish the customs value (usually the price you paid the supplier), then multiply that value by the duty rate for your HS code and country of origin. Add VAT or GST โ charged on top of duty in most countries but not the US โ plus broker and handling fees. Always confirm rates against your destination country's official tariff schedule, since they change.
Four steps to your import duty
Work through them in order โ each one feeds the next.
- 1
Find the correct HS code (tariff classification)
Every product has a Harmonized System (HS) code โ 6 digits internationally, extended to 8โ10 digits by each country. The code decides your duty rate, so getting it right is the whole game. Use your destination country's official tariff schedule (for example the US HTS or the EU TARIC) to look up your product, and when a classification is ambiguous, request a binding ruling from your customs authority. A wrong code can mean underpaying (penalties later) or overpaying for years.
- 2
Establish the customs value
Duty is charged on the customs value, not the retail price. Most countries use the transaction value โ what you actually paid the supplier. Whether freight and insurance are included depends on the country: the US assesses duty on the FOB (goods) value, while the EU, UK, and many others use the CIF value (goods + international freight + insurance). Keep the commercial invoice, packing list, and freight/insurance documents, because customs will reconcile against them.
- 3
Apply the duty rate to the customs value
Multiply the customs value by the ad-valorem duty rate for your HS code. Rates vary enormously โ many consumer goods sit somewhere in the 0%โ12% band, but categories like footwear, apparel, and certain steel or aluminium products can run much higher, and country-specific measures (anti-dumping duties or additional Section 301-style tariffs on Chinese-origin goods) can stack on top. Always confirm the current rate for the exact code and country of origin, since these change.

Add VAT / GST / sales tax and other import charges
Import duty is usually not the last charge. Most countries then apply VAT or GST on top of (customs value + duty), often at the standard domestic rate. The United States has no federal import VAT โ state sales tax works differently โ while the EU (rates commonly ~17%โ27% by member state), the UK (20%), and many others levy import VAT at clearance. Budget also for customs broker fees, port/handling, and merchandise-processing-type fees where they apply.
A simple illustration
These figures are illustrative only, to show the mechanics โ your real rates depend entirely on your HS code and destination country. Say you import goods with a customs value of $10,000 and a duty rate of 5%.
Note how VAT is charged on the value plus the duty, not the value alone. In a US import there would be no federal import VAT, so the total charge above the duty would look very different. This is exactly why you should model landed cost per country rather than assume one number.
Tools that help
- Your destination country's official tariff schedule for the exact duty rate
- A binding tariff ruling from customs when the HS code is unclear
- A licensed customs broker for the legally correct classification and clearance
- A landed-cost spreadsheet or calculator to model value + duty + VAT + fees
Mistakes that cost you
- Guessing the HS code instead of verifying it against the official tariff schedule โ the single most common and most expensive error.
- Assuming duty is calculated on the retail price rather than the customs (transaction) value.
- Forgetting that VAT/GST is charged on top of duty, which quietly inflates your true landed cost.
- Overlooking country-of-origin surcharges such as anti-dumping duties or additional tariffs on Chinese-origin goods.
- Trusting a supplier's casual 'duty is about X%' estimate as if it were an official ruling.
