Regulation Overview
https://hts.usitc.gov/
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.
The HTS is based on the World Customs Organization's international Harmonized System—the first six digits are standardized globally, while the remaining four are US-specific. USITC publishes multiple revisions per year. In 2025–2026 alone, revisions addressed Section 301 tariff expansions, reciprocal tariff frameworks, semiconductor-specific actions, and the elimination of de minimis duty-free treatment.
HTS compliance requires product-level technical data—material composition, function, construction, and intended use—from every supplier. When tariff rates shift or new actions take effect, your entire import portfolio requires reclassification review.
Key Components / Sub-Frameworks
US importers of record filing customs entries with CBP
Foreign manufacturers and exporters shipping to US buyers
Customs brokers acting on behalf of importers
Companies claiming preferential duty treatment under FTAs (USMCA, etc.)
Distributors and resellers importing finished goods or components
E-commerce sellers shipping products to US consumers
Key Thresholds
USITC published multiple HTS revisions in 2025 alone—covering reciprocal tariffs, semiconductor actions, Section 301 expansions, and country-specific trade frameworks. Each revision creates new Chapter 99 subheadings that layer additional duties on top of existing rates. Your commodity master was current in January. By March, 200 SKUs map to changed codes. Your team discovers the gap during a CBP focused assessment.
CBP detains your shipment and requests classification rationale. You classified the product two years ago based on a supplier spec sheet. The spec sheet is in an engineer's inbox. The classification rationale was never documented. You cannot demonstrate reasonable care. CBP assesses negligence penalties at 2x the lost revenue—retroactive across five years of entries.
Your product has a Column 1 duty rate of 3.5%. But it originates in China, so Section 301 adds 25%. A reciprocal tariff provision in Chapter 99 adds another surcharge. Without mapping every SKU against Column 1, Chapter 99, Section 232, and Section 301 layers simultaneously, you cannot calculate true landed cost—or identify tariff engineering opportunities.
HTS classification requires material composition, construction details, functional specifications, and country of origin—from every supplier. But suppliers provide commercial descriptions, not tariff-grade technical data. Without structured product data collection at the supplier level, your classification team works from incomplete information, and every entry carries unquantified penalty risk.
Certivo In Action
Certivo in Action — HTS Workflow
From Manual Lookups to Automated Attribute Mapping
CORA collects supplier product data and extracts tariff-relevant attributes automatically. Your trade compliance team focuses on high-risk reclassification decisions—not data entry and spreadsheet maintenance.
Reasonable Care Evidence Acceleration
Generate complete, CBP-ready classification rationale packages in hours—not the weeks of manual compilation across customs brokers, engineers, and procurement teams.
Proactive Tariff Classification Compliance
When USITC publishes revisions, Certivo crosswalks your commodity master instantly. Know which SKUs are affected before your next entry filing—not after a CBP focused assessment.
Key Statistics
Frequently Asked Questions
What products require HTS classification?
Every product imported into the United States must be assigned a 10-digit HTS code. Since the elimination of de minimis duty-free treatment in August 2025, this applies to all shipments regardless of value. The HTS covers over 17,000 product classifications organized across 99 chapters. Certivo maintains a continuously updated HTS commodity master that maps your product portfolio against current classifications and revision changes.
What are the penalties for HTS misclassification?
CBP enforces HTS compliance under 19 USC §1592 across three culpability levels. Negligence carries penalties up to 2x lost revenue or 20% of dutiable value. Gross negligence reaches 4x lost revenue or 40% of dutiable value. Fraud penalties can equal the full domestic value of the merchandise and may trigger criminal prosecution. CBP has a 5-year lookback window for assessing additional duties on past entries.
How often does the HTS change?
USITC publishes multiple HTS revisions per year. In 2025–2026, revisions have addressed Section 301 tariff expansions, reciprocal tariff frameworks, semiconductor-specific trade actions, and country-level trade agreement implementations. Each revision can create new Chapter 99 subheadings, modify duty rates, or reclassify product categories. CORA monitors all USITC revisions and alerts you when changes affect your classified SKUs.
How does Certivo support reasonable care compliance?
Certivo collects the supplier-level product data—material composition, functional specifications, construction details, and country of origin—that forms the foundation of reasonable care documentation. CORA extracts tariff-relevant attributes, maps them to GRI-based classification rationale, and generates audit-ready packages. When CBP requests classification evidence during a focused assessment, the documentation is ready in hours.
How does HTS classification relate to Section 301 tariffs and USMCA compliance?
HTS classification is the gateway to all tariff layers. The 10-digit HTS code determines Column 1 duty rates, Section 301 and 232 additional tariffs via Chapter 99, and eligibility for preferential FTA rates under USMCA. Certivo validates supplier data against classification, origin, and tariff layer requirements simultaneously—one supplier submission covers HTS compliance, Section 301 exposure, and USMCA qualification evidence.
