OVERVIEW
Importing Plastics, Polymers & Plastic Articles from Canada
Importing plastics 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.
Plastics 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
Canada exports engineered plastics, plastic resins, and finished plastic products duty-free under USMCA. Strong petrochemical base in Alberta and Ontario provides competitive raw material supply.

COMPLIANCE — EPA/TSCA / FDA / CPSC
US Compliance Requirements for Plastics Imports
Regardless of origin country, plastics imports must satisfy the following US regulatory requirements before or at the time of CBP entry filing:
- TSCA (Toxic Substances Control Act) compliance — all chemical substances in plastics must appear on the TSCA Inventory; new chemicals require EPA premanufacture notice (PMN)
- FDA Food Contact Notification (FCN) required for plastics intended for food packaging or food-contact applications (21 CFR Parts 174–186)
- CPSC testing requirements for plastic consumer products — lead and phthalate limits for children's products under CPSIA Section 101/108
- California Prop 65 compliance for plastics containing listed chemicals (BPA, phthalates, cadmium, lead)

FREQUENTLY ASKED QUESTIONS
FAQs — Importing Plastics from Canada
What are the current US import tariffs on apparel from Vietnam in 2026?
The effective US tariff rate for plastics from Canada is: 0% USMCA. Canada exports engineered plastics, plastic resins, and finished plastic products duty-free under USMCA. Strong petrochemical base in Alberta and Ontario provides competitive raw material supply.
What compliance agencies regulate plastics imports from Canada?
Plastics imports require compliance with: EPA/TSCA, FDA, CPSC. Specific requirements include: TSCA (Toxic Substances Control Act) compliance — all chemical substances in plastics must appear on the TSCA Inventory; new chemicals require EPA premanufacture notice (PMN) and FDA Food Contact Notification (FCN) required for plastics intended for food packaging or food-contact applications (21 CFR Parts 174–186).
What documents are required to import plastics from Canada?
Required documents include: Commercial Invoice with polymer type, grade, and end-use application; Packing List; Bill of Lading; TSCA Certification (EPA Form 7710-56) — required for all chemical imports. Additional: FDA food-contact compliance documentation (if applicable); Country of Origin Declaration. Ensure all documents are prepared before the shipment departs Canada.
How long does customs clearance take for plastics from Canada?
Typical timeline: 20–35 days (ocean from Asia); 10–18 days (ocean from Europe); 5–10 days (truck from Mexico/Canada). 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 plastics from Canada?
No Section 301 or Section 232 surcharges apply to Canada-origin plastics. Only base MFN rates (or FTA preferential rates where applicable) apply.
What is the effective total landed duty rate for importing plastics from Canada in 2026?
0% USMCA. This reflects the combined rate including base MFN replaced by USMCA preferential rate.
What is the most critical compliance issue for importing plastics from Canada that most buyers overlook?
Rules of origin compliance. USMCA preference is only valid when goods meet the specific origin threshold — typically regional value content (75% for automotive, 60-65% for general goods) or a qualifying tariff shift. Incorrectly claiming FTA preference when documentation is insufficient results in retroactive duty assessment at the difference between preferential and MFN rates, plus potential penalties.
What HTS codes and duty rates apply to plastic goods imports?
Plastics are classified under HTS Chapters 39 (plastics and articles thereof). Raw plastic materials (resins, polymers): HTS 3901–3914, typically 3.4%–6.5% MFN. Plastic articles: HTS 3916–3926, varying from 0% to 6.5% MFN. Plastic bags and film (3923–3924) face 3%–6.5% MFN. China-origin plastics add 25% Section 301 for most HS codes. Anti-dumping orders exist on certain plastic bags from China and Vietnam — verify via CBP ADD/CVD portal before importing packaging products.
What TSCA and EPA regulations apply to imported plastic products?
TSCA Section 13 requires that imported chemical substances, including plastic resins, comply with TSCA regulations — importers must certify compliance or non-coverage at entry. EPA restricts certain chemical substances in plastics, including phthalate plasticizers in children's products (CPSC/TSCA). California Prop 65 requires warnings for plastics containing listed chemicals (lead, phthalates, bisphenol A). Single-use plastics may face state-level restrictions. Maintain SDS (Safety Data Sheets) and chemical composition records for all imported plastic products.
How does Section 301 affect plastics importers sourcing from China?
Most plastic articles from China are subject to 25% Section 301 tariffs under List 3 or 4A (many List 4A products at 7.5%). This stacks on MFN base rates of 3.4%–6.5%, creating effective duties of 10.4%–31.5% on Chinese plastics. Importers have responded by shifting sourcing to Vietnam, Thailand, Malaysia, and Mexico. However, CBP enforces anti-circumvention rules — plastic goods with Chinese-origin resin that undergo only minor processing in a third country may still be classified as Chinese origin.
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.
