OVERVIEW
Importing Industrial Chemicals & Chemical Products from Canada
Importing chemicals from Canada into the United States carries low compliance risk, with an effective duty rate of 0% USMCA. The USMCA agreement provides significant tariff advantages — qualifying goods may enter at preferential or zero-duty rates, making this a cost-efficient import corridor.
Chemicals imported from Canada to the United States is subject to CBP entry requirements, applicable HTS-based duty rates, and agency compliance clearances. This guide covers the complete import process for 2026.
⚠ Key Trade Intelligence — Canada Origin

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

Typical timeline: 20–40 days (ocean; hazmat routing may add delays); 3–10 days (air for non-hazmat chemicals). CBP clearance typically takes 1–3 business days for compliant entries. Complex entries (AD/CVD, formal entry review, or examination) may require 5–15 additional business days.
Are there Section 301 or Section 232 tariffs on chemicals from Canada?
No Section 301 or Section 232 surcharges apply to Canada-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.
What is the US de minimis threshold for Canadian shipments?
The US de minimis threshold is $800 for all origins including Canada. Shipments valued at $800 or less may enter duty-free via informal entry. For formal entries above $800, USMCA provides 0% preferential rates for qualifying goods. CBP clearance for Canadian goods is highly automated under FAST (Free and Secure Trade) programs — pre-approved carriers and importers experience expedited processing.
Do softwood lumber and Canadian steel face special tariffs?
Softwood lumber from Canada faces AD/CVD orders (Case A-122-857/C-122-858) with combined rates typically ranging 8%–18% depending on the producer and province of origin. Canadian steel was exempted from Section 232 under USMCA but is subject to TRQ monitoring arrangements. Any future breakdown in USMCA trade relations could reinstate Section 232 on Canadian steel — a scenario that has occurred before.
How does USMCA de minimis treatment work for Canadian-manufactured goods containing foreign inputs?
USMCA's de minimis rule (Chapter 32) allows goods to qualify for USMCA preferential rates even if up to 10% of the good's net cost consists of non-originating materials that don't complete the required tariff shift. This provides flexibility for manufacturers using small quantities of non-USMCA components. The rule does not apply to textiles (yarn-forward applies strictly) or certain agricultural products.
