Frequently asked questions

Model Context Protocol (MCP) servers connect Avalara HS Code Classification APIs and curated Avalara Trade and Tariff Library APIs to AI agents and partner platforms. This enables compliance tasks like tariff code classification and trade restrictions management to run automatically inside ERPs, marketplaces, and supply chain systems. The result is faster onboarding, fewer errors, and smoother global trade operations.

Harmonised System (HS) codes are internationally standardised 6-digit codes used to classify traded goods. Harmonised Tariff Schedule (HTS) codes are 10-digit extensions of HS codes used by the US to determine import duties and regulations. Tariff codes generally refer to classifications used to impose duties on imports, varying by country and often based on the HS system. Schedule B codes are 10-digit codes used by the U.S. to classify exported goods, maintained by the U.S. Census Bureau .

HS codes are important because they’re the language of international goods trade. Not only is HS classification a mandatory requirement for customs, but submitting an inaccurate HS code can result in an overpayment or underpayment of duties and taxes or a violation of trade compliance laws, which can lead to goods being delayed at the border and an assessment of penalties and fines.

It’s not recommended to use the same HS code for multiple products if they’re different in composition, form, or function. HS codes are assigned based on the specific characteristics of the product, so each product should be classified under the appropriate code that best describes its attributes.

HS codes are periodically reviewed and updated by the World Customs Organisation (WCO) to ensure that they reflect changes in technology, trade practices, and new products entering the market. The most recent version of the HS (HS 2022) became effective on 1 January 2022. However, many countries still use older HS versions, which are incompatible with HS 2022. It’s important to know that country-specific tariff codes and their associated duty rates can change several times a year as well.

All Avalara Tariff Code Classification offerings classify products to the country-specific tariff level and help with taxability determination and shipment requirements, although the level of support from our team of experts varies to cater to your needs.

Automated HS code classification is achieved through the deployment of ML and AI technology. Avalara Tariff Code Classification offerings combine an intuitive AI-enabled tool with machine learning and human expertise.

The penalties for incorrect HS code classification vary depending on the country and the severity of the violation. However, in a recent Avalara survey , respondents reported that the incorrect classification of goods resulted in more frequent delays in customs, added costs of tariffs and duties, extra supply chain costs, and failure to meet customers' delivery expectations.
