Customs duty is a type of tax, or tariff, imposed on goods when they’re transported from one country to another. Duties make imported goods more expensive, discouraging imports and protecting each country’s domestic industry while also generating revenue for the government.
The duty rate is determined by the Harmonized System code (also known as an HS code, or tariff code) for each product. These 8–12-digit codes are part of the Harmonized System, an internationally standardized system of names and numbers to classify physical goods. While the first six digits of tariff codes are the same for a product regardless of where you’re exporting it, the last characters vary by country. Each tariff code corresponds to its own customs duty rate, so it’s crucial to get the right code for your products in each country for correct duty calculation. Automated solutions like Avalara Managed Tariff Code Classification can help you efficiently and confidently assign country-specific tariff codes to your products.
The customs duty rate is typically assessed as a percentage of the value of the product, but can sometimes be assessed based on other factors, such as weight, number of units, or other item-specific criteria.
Keep in mind that the duty rate can be assessed on the total value of the shipment, including shipping costs. Make sure you know what the policy is in the import country so you determine the correct amount.
Each country typically has a minimum value below which duties are not assessed, called the de minimis value. If your shipment’s value is below this threshold, customs duty may not apply. This threshold amount varies wildly. For example the de minimis in the United States is $800 US (with certain exceptions), but in Canada, it’s $20 CAD, one of the lowest in the world. Therefore, a retail shipment from France valued at $500 and shipped to an end customer in the U.S. may not be subject to customs duty, but would be if the end customer was in Canada.
