About This Dataset
The US Harmonized Tariff Schedule (HTSUS) contains over 10,000 active 10-digit classification codes that determine the exact duty rate every imported product pays. But the base MFN (most-favored nation) rate is only the starting point — in 2026, most products also carry additional layered tariffs under Section 301 (China), Section 232 (steel and aluminum), IEEPA (reciprocal tariffs), or a combination of all three.
This database surfaces the full tariff stack for key HTS codes across 27+ chapters. Each record includes the MFN general rate, applicable Section 301 surcharge, Section 232 rate, USMCA preferential rate, and compliance flags for FDA, USDA, EPA, and textile visa requirements. Download the full dataset in CSV format for use in landed cost models, compliance audits, and supply chain analysis.
Data sourced from USITC HTSUS 2026, Federal Register tariff notices, and USTR Section 301 lists. Updated continuously to reflect Federal Register changes. Verify applicable rates at time of entry — tariff schedules are subject to executive action, court rulings, and WTO dispute outcomes without notice.
Current Tariff Layers by Regime
Multiple tariff authorities stack additively on the same product. A Chinese electronics shipment can owe MFN + Section 301 + IEEPA simultaneously.
Duty Stacking Examples by Origin and Product (2026)
The effective tariff rate is the sum of all applicable layers. The examples below show how duty stacking works in practice for common import scenarios.
| Product / HTS Chapter | Origin | MFN Rate | Section 301 | Section 232 | IEEPA | Effective Rate | USMCA Option |
|---|---|---|---|---|---|---|---|
| Electronics (Ch. 85) | China | 0–3% | 25% | — | 30%+ | 55–58%+ | N/A |
| Steel flat-rolled (Ch. 72) | Global (non-USMCA) | 0% | — | 25% | 10%+ | 35%+ | 0% (CA/MX) |
| Knitted apparel (Ch. 61) | China | 16–37% | 7.5–25% | — | 30%+ | 53–92%+ | Limited |
| Machinery (Ch. 84) | China | 0–2% | 25% | — | 30%+ | 55–57%+ | ~0–2% (MX) |
| Footwear (Ch. 64) | China | 8–48% | 7.5% | — | 30%+ | 45.5–85.5%+ | 5–20% (MX) |
| Aluminum products (Ch. 76) | India | 0–5% | — | 10% | 26% | 36–41% | 0% (CA/MX) |
| Furniture (Ch. 94) | Vietnam | 0% | — | — | 46% | 46% | N/A |
| † IEEPA rates reflect 90-day pause (10%–30% for most countries). Full reciprocal rates resume after pause expiry — verify at USTR.gov before entry. China not included in pause. | |||||||

Compliance Notes: Duty Stacking Rules, FTA Eligibility & Section 122
Duty Stacking Rules
Section 301, Section 232, and IEEPA tariffs stack additively on top of the MFN general rate. A product subject to all three authorities pays MFN + §301 + §232 + IEEPA simultaneously. However, IEEPA executive orders may modify or pause §301 treatment — always verify at USTR.gov and the Federal Register. AD/CVD duties stack further on top of all other layers.
USMCA FTA Eligibility
Goods qualifying under USMCA rules of origin (minimum 70%–75% regional value content) pay 0% MFN duty and are exempt from Section 232 tariffs on steel and aluminum. USMCA goods are NOT exempt from Section 301 tariffs (which are origin-specific to China) but are generally exempt from IEEPA reciprocal tariffs while the US-Canada-Mexico trade relationship remains intact under the July 1, 2026 joint review.
Section 122 Invalidation
The Court of International Trade ruled on May 7, 2026 that Section 122 tariffs (10% global surcharge, February 24 – July 24, 2026) were imposed beyond statutory authority. Importers who paid Section 122 duties may be eligible for refunds. The CAPE portal at cbp.gov/cape handles refund claims. The ruling is under appeal — continue monitoring the Federal Register for implementation guidance and protest deadlines.
IEEPA Refund Program
The CAPE (Customs and Border Protection Automated Protest & Entry) portal allows importers to claim refunds for IEEPA-authority duties paid on qualifying entries. Phase I covers straightforward entries. Estimated $166B+ in refunds available. Requires an ACE (Automated Commercial Environment) account. File a CAPE declaration identifying entries where IEEPA tariffs were charged. Consult a licensed customs broker for complex entries.
Section 301 Exclusions
Active Section 301 exclusions reduce or eliminate the §301 surcharge for specific HTS codes or product descriptions. Over 2,400 exclusions have been granted since 2018. Verify your specific HTS code against the active exclusion list at USTR.gov before calculating duties — an exclusion can reduce effective rates from 25% back to MFN. Exclusions are time-limited and product-specific.
July 24, 2026 Deadline
July 24, 2026 is the statutory deadline for Section 301 remedy determinations covering 16+ economies including the EU, Japan, South Korea, Taiwan, and Vietnam. Potential new tariffs of 15%–50% on electronics, semiconductors, and pharmaceuticals from these countries. Import large volumes of high-risk categories before this date if supply chain strategy permits. Source: USTR Section 301 Investigation Docket.
