Duty is calculated based on the product’s classification, value, and origin. It’s assessed by customs and must be paid before the goods are released for domestic delivery. For example, importing watches from outside the EU may incur a 5% duty, depending on the commodity code.

Import duty is a tax levied by governments on goods crossing international borders, calculated based on product classification, value, and country of origin. These charges protect domestic industries, generate revenue, and implement trade policies—directly impacting your landed costs and pricing strategies.

Understanding duty implications is crucial for international trade. For example, importing watches from outside the EU may incur 4.5% duty on mechanical watches but 0% on smartwatches, depending on the precise commodity code classification—a difference that significantly affects competitive pricing.

How Duties Impact Your Business

Duties affect every aspect of international trade:

Duty Calculation Components:

• Product classification (HS/tariff code)

• Customs valuation method

• Country of origin

• Trade agreements

• Special programmes

Common Duty Types:

• Ad Valorem: Percentage of value (most common)

• Specific: Fixed amount per unit

• Compound: Combination of both

• Anti-dumping: Protection against unfair pricing

• Countervailing: Offset foreign subsidies

Real-World Complexity: A UK fashion retailer importing from various sources:

• Vietnam cotton t-shirts: 12% duty

• Bangladesh cotton t-shirts: 0% (GSP)

• Turkey cotton t-shirts: 0% (Trade agreement)

• China synthetic t-shirts: 12% + anti-dumping

• USA cotton t-shirts: 12%

Same product category, vastly different duty impacts based on origin and agreements.
