Are there Section 301 or Section 232 tariffs on chemicals from Mexico?
No Section 301 or Section 232 surcharges apply to Mexico-origin chemicals. Only base MFN rates (or FTA preferential rates where applicable) apply.
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.
How do I claim USMCA preferential tariff treatment for goods from Mexico?
To claim USMCA preference, you (or your customs broker) must have a valid Certificate of Origin from the Mexican exporter at the time of entry. The certificate confirms rules of origin compliance and must be retained for 5 years for CBP audit purposes. You do not need to transmit it to CBP at entry, but it must be produced immediately upon request.
Are goods manufactured in Mexico from Chinese components eligible for USMCA?
Not automatically. USMCA requires sufficient transformation in North America — simple assembly of imported components without a qualifying tariff shift or meeting RVC thresholds generally does not qualify. The specific rules vary by HTS code under USMCA Annex 4-B. Consult a licensed customs broker or trade attorney to evaluate whether your specific product meets USMCA rules of origin.
What are the IMMEX program implications for importing manufactured goods from Mexico?
Mexico's IMMEX program allows manufacturers to temporarily import inputs duty-free for incorporation into export goods. IMMEX-manufactured goods exported to the US may qualify for USMCA preferential rates provided rules of origin are met. CBP expects importers claiming USMCA to verify that foreign inputs were either North American origin or sufficiently transformed — IMMEX manufacturing records are key supporting documentation.
