The Harmonized Tariff Schedule (HTS) is the system used by the United States to classify imported goods and determine the applicable duty rates, quotas, and trade requirements. Based on the global Harmonized System (HS) managed by the World Customs Organization, the HTS assigns a unique 10-digit code to every product entering the country. These codes not only ensure consistency in trade reporting but also establish the foundation for calculating customs duties, identifying import restrictions, and complying with U.S. trade laws.

For supply chains, the HTS has a direct and far-reaching impact. Accurate tariff classification can influence landed costs, sourcing decisions, and overall competitiveness in global markets. Misclassification, on the other hand, can lead to costly delays, penalties, or compliance risks. As tariffs and trade policies shift, businesses must stay current with HTS updates to avoid disruptions and optimize supply chain strategies. By managing tariff codes effectively, importers can reduce unexpected expenses, improve trade compliance, and build more resilient supply chains in an increasingly complex global trade environment.
