Harmonized Tariff Schedule (HTS) Classification Compliance

Trade, Export Controls & Sanctions

Harmonized Tariff Schedule of the United States (HTSUS)

17,000+ HTS Codes. Reciprocal Tariffs Shifting Monthly. Is Every SKU in Your Portfolio Classified Correctly?

HTS classification determines the duty rate, trade agreement eligibility, and regulatory treatment for every product entering the United States. Misclassification triggers CBP penalties up to 4x lost revenue—and the HTS has undergone more revisions in 2025–2026 than any period in recent history. De minimis exemptions are eliminated. Section 301, 232, and reciprocal tariff layers change quarterly.

Certivo automates HTS classification evidence management from supplier product data to audit-ready customs documentation.

What is the Harmonized Tariff Schedule?

The Harmonized Tariff Schedule is the foundational classification system for all goods imported into the United States and the backbone of US trade compliance. For supply chain and trade compliance teams, the primary obligation is assigning correct 10-digit HTS codes—codes that determine applicable duty rates, eligibility for preferential trade programs, and exposure to special tariff actions under Section 301, Section 232, or reciprocal tariff provisions.

Key Components / Sub-Frameworks

• Obligation: Legal framework for all classification decisions
• General Rules of Interpretation (GRI): Six rules governing how products are classified within the HTS
• Section/Chapter Notes: Legally binding notes defining scope of each HTS chapter
• Column 1 (General): Normal Trade Relations (MFN) duty rates
• Column 2: Higher duty rates for non-NTR countries
• Chapter 99: Special tariff provisions (Section 301, 232, reciprocal tariffs)
• Binding Rulings (19 CFR Part 177): CBP-issued legally binding classification decisions
