US Compliance Requirements for Chemicals Imports
Regardless of origin country, chemicals imports must satisfy the following US regulatory requirements before or at the time of CBP entry filing:
- TSCA Section 12(b) import certification — all chemical substances must be on the TSCA Inventory; new substances require EPA premanufacture notice (PMN) before importation
- DOT hazardous materials shipping requirements (49 CFR Parts 171–180) — UN hazmat classification, proper shipping name, and hazmat packaging required
- EPA FIFRA registration required for pesticides, herbicides, and antimicrobial products before they can be imported or distributed in the US
- OSHA Hazard Communication Standard (29 CFR 1910.1200) — Safety Data Sheets (SDS) must accompany all chemical imports and conform to GHS format

Are there Section 301 or Section 232 tariffs on chemicals from Taiwan?
No Section 301 tariffs apply to Taiwan-origin goods. Section 232 applies: 25% on steel and 10% on aluminum products from Taiwan.
What TSCA compliance requirements apply to imported chemical substances?
The Toxic Substances Control Act (TSCA) requires that all imported chemical substances either be on the TSCA Chemical Substance Inventory or qualify for an exemption. Importers must certify compliance or non-coverage at entry on CBP Form 3540. New chemical substances require pre-manufacture notification (PMN) to EPA before import. Certain high-risk substances are subject to TSCA Section 5 significant new use rules (SNUR). Non-TSCA-compliant chemical imports are subject to CBP refusal of entry and EPA enforcement action.
What HTS codes and duty rates cover industrial chemicals?
Chemicals are classified primarily under HTS Chapters 28–29. Inorganic chemicals (Chapter 28): rates typically 0%–5.5% MFN. Organic chemicals (Chapter 29): 0%–6.5% MFN. Fertilizers (Chapter 31): 0%–5%. Plastics raw materials (Chapter 39): 3.4%–6.5%. Many specialty chemicals from China face 25% Section 301. Several categories — including certain industrial chemicals, pharmaceutical precursors, and agricultural inputs — have binding WTO zero duties. Consult a licensed customs broker for 10-digit HTS classification since rates vary significantly within each 4-digit heading.
Are hazardous chemicals subject to special import procedures or restrictions?
Yes. Hazardous chemicals face multiple regulatory requirements: (1) OSHA Hazard Communication Standard — SDS and GHS labeling required for workplace chemicals, (2) EPA TSCA and RCRA regulations on importing hazardous waste and regulated substances, (3) DOT 49 CFR hazmat regulations for transport of hazardous materials — proper UN classification and packaging required, (4) DEA controls on listed chemical precursors for drugs of abuse, (5) BIS Export Administration Regulations (EAR) for dual-use chemicals with weapons potential. Some chemical imports from China or Russia require additional screening under OFAC sanctions review.
Does Taiwan have a free trade agreement with the United States?
No. Taiwan and the US do not have a formal FTA. The US-Taiwan Initiative on 21st-Century Trade (launched 2022) covers trade facilitation, digital trade, and labor standards but does not provide tariff preferences. Taiwanese goods pay standard MFN rates. Despite no FTA, Taiwan is a top-10 US trading partner — ITA zero rates cover most semiconductor and electronics trade, offsetting the absence of FTA access.
Are Taiwanese semiconductors and electronics subject to any additional US tariffs?
Taiwan is not subject to Section 301 tariffs. Section 232 applies to Taiwanese steel and aluminum. Semiconductors and most electronics from Taiwan benefit from ITA zero rates. The US CHIPS Act incentivizes US domestic semiconductor manufacturing but does not create tariff restrictions on Taiwanese imports — the strategic US-Taiwan trade relationship remains strong and tariff conditions stable as of 2026.
What compliance documentation is required to import semiconductors from Taiwan?
TSMC and other Taiwan-origin semiconductors require: correct Schedule B/HTS classification (HTS 8542.31–8542.39 for ICs), EAR classification for advanced chips with potential dual-use applications, FCC Part 15 compliance for finished electronic devices, and end-use/end-user certifications for advanced AI chips or high-bandwidth memory subject to export control. Maintain full technical specifications for CBP classification review.
