OVERVIEW
Importing Industrial Chemicals & Chemical Products from China
Importing chemicals from China into the United States carries high compliance risk, with an effective duty rate of 25% Section 301 (Lists 2/3) + 0%–6.5% MFN = ~25%–31.5% effective. This corridor carries both Section 301 and Section 232 surcharges stacked on top of the base MFN rate, making it one of the highest-cost import corridors for US buyers. AD/CVD orders may apply to specific chemicals sub-categories — verify against CBP's ADD/CVD portal before importing.
Chemicals imported from China 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 — China Origin
Chinese industrial chemicals face 25% Section 301 on Lists 2 and 3. AD/CVD orders exist on specific Chinese chemicals including glycine, saccharin, and chlorinated isocyanurates. TSCA and EPA compliance requirements are stringent regardless of 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

How long does customs clearance take for chemicals from China?
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 China?
Yes. China-origin chemicals is subject to Section 301 additional tariffs (7.5%–25% depending on HTS code and List). Section 232 duties also apply: 25% on steel products, 10% on aluminum. Total effective duty is substantially higher than the base MFN rate.
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 are the current Section 301 tariff rates on Chinese imports in 2026?
Section 301 tariffs range from 7.5% (List 1 goods, many industrial inputs) to 25% (List 3 and 4A goods, which cover most manufactured products). USTR publishes the current lists at ustr.gov. Most exclusions issued in 2019–2020 have expired. Effective rates for manufactured goods from China are typically 25% Section 301 on top of the applicable MFN base rate.
Does my Chinese-origin product qualify for any Section 301 exclusions?
Most Section 301 exclusions have expired. USTR has issued limited targeted renewals for specific HTS codes where no US or alternative-country substitutes exist. To check current exclusion status, search USTR's Section 301 exclusion portal by HTS code. If no exclusion applies, the full Section 301 surcharge applies — there is no mechanism to appeal the tariff itself, only to seek a formal exclusion through USTR.
What supply chain documentation is required to comply with UFLPA for goods from China?
Under UFLPA, importers must maintain documentation proving no inputs originate from the Xinjiang Uyghur Autonomous Region. Required documentation includes supplier attestations, raw material sourcing records, and ideally third-party supply chain audit reports. CBP can detain goods it reasonably suspects contain Xinjiang-origin inputs — the burden of proof is on the importer, not CBP, to demonstrate compliance.
