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)

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 Japan?
No Section 301 tariffs apply to Japan-origin goods. Section 232 applies: 25% on steel and 10% on aluminum products from Japan.
What is the effective total landed duty rate for importing plastics from Japan in 2026?
0%–6.5% MFN; no additional tariffs. This reflects the combined rate including base MFN rate plus Section 232 tariff.
What is the most critical compliance issue for importing plastics from Japan that most buyers overlook?
Section 232 steel/aluminum applicability. Products with significant steel or aluminum content from Japan face 25% and 10% additional duties respectively. Confirm whether your specific HTS code falls within the Section 232 product scope before importing — misclassification can result in customs penalties and back-duty assessments.
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.
Does Japan have a free trade agreement with the US and how does it affect duties?
The US-Japan Trade Agreement (USJTA, January 2020) covers agricultural goods and some manufactured products but does not eliminate duties across most manufactured goods categories. Japan is not subject to Section 301 tariffs. Section 232 applies to Japanese steel with a country-specific TRQ arrangement. A comprehensive US-Japan FTA covering all manufactured goods has not been concluded as of 2026.
What Section 232 TRQ arrangement applies to Japanese steel and aluminum?
Japan and the US reached a Section 232 TRQ arrangement in 2022 (mirroring the US-EU structure), allowing specified volumes of Japanese steel to enter at 0% Section 232 per quarter. Japan receives country-specific quota allocations per product category. Above-quota Japanese steel faces the full 25% Section 232 surcharge. Monitor CBP quarterly quota reports for real-time quota availability.
What compliance considerations apply to importing precision equipment from Japan?
Japanese precision equipment (CNC machines, optical instruments, medical devices) requires: FDA registration and 510(k) clearance for medical devices, FCC authorization for RF-emitting components, EPA/DOE energy efficiency standards for applicable categories, and OSHA safety compliance for industrial machinery. Japanese manufacturers typically provide comprehensive compliance documentation — verify it covers US-specific (not just CE/JIS) requirements.
