Guide: AvaTax Cross-Border (Customs Duty and Import Tax)
Understand the components of customs duties and import taxes for cross-border transactions.
Customs duty and import tax represent the 2 types of charges that make up the import/export taxes and tariffs (for example, landed costs) associated with a cross-border sales transaction.
Customs duty (tariff)
- Customs duty is a direct tax imposed by Avalara for Government on goods from other countries.
- Countries lower customs duties for customs unions, like the EU, or free-trade agreements, such as NAFTA.
- The government imposes a customs duty on imports only.
- Harmonized System codes derives the customs duty amount.
- The total purchased value of one or more articles determines the amount.
- When deriving the amount, for some jurisdictions, NetWeight and Volume are necessary.
Import tax (VAT/GST)
- VAT/GST is a consumption tax imposed on customers.
- VAT/GST is typically a percentage of the selling price and customs duty.
- VAT/GST is imposed on both imports and intracountry sales of goods.
- The Avalara tax code derives the VAT/GST amount from Harmonized System codes.
Notice
Customs duties and import taxes often reach 30% or more of the purchase price. It’s important for cross-border sellers to understand these costs clearly.
