Customs duty calculations at checkout
This article applies to:AvaTax
After you set up AvaTax Cross-Border and connect your business application to AvaTax, customs duties and other import taxes are automatically included at checkout.
Requirements for customs duty calculations
- All products in the shopping cart must have a fully qualified harmonized tariff code assignment in AvaTax
If any item in the order doesn't have a complete tariff code, cross-border calculations will be skipped for the entire order. - You (the seller) must be the importer of record in the destination country
If the buyer is the importer of record, duties aren't included in the transaction total. Instead, fees are calculated after the order is submitted and stored in AvaTax. - The Ship From and Ship To destinations must be in different countries
Make sure your shipping information is accurate. - If calculating preferential treaty rates, transaction data must include treaty parameters
Transaction parameters are applied on the Item level as part of the CreateTransaction API model.
Identify customs duty charges in your business application or system
Check your business application's documentation to see how customs duties are broken down at checkout or within individual orders. For example, a WooCommerce checkout experience may describe customs duty calculations as "Import Fees".
Calculating preferential treaty rates at checkout
To calculate preferential duty rates, your transaction data must include trade agreement parameters. When the parameters are present, AvaTax applies the appropriate preferential duty rate instead of the Most Favored Nation (MFN) rate.
