Acrylic acid (prop-2-enoic acid) under TSCA

C3H4O2 · 丙烯酸

Status: Listed. Acrylic acid is on the TSCA Inventory and is currently listed as TSCA Active. **OSHA has no specific federal PEL for acrylic acid in 29 CFR 1910.1000 Table Z-1**; practitioner-facing limit is the ACGIH TLV 2 ppm 8-hr TWA with skin notation (verify current ACGIH TLV and any state OSHA PEL such as Cal/OSHA against https://www.osha.gov/annotated-pels before relying). NOT on EPA RMP threshold list. NOT on DEA scheduling. NOT on California Proposition 65 (verified absent from OEHHA https://oehha.ca.gov/proposition-65/proposition-65-list at audit date 2026-05-12). **TRI Section 313 listed**: Form R annual reporting required. NO active US AD/CVD case on Chinese-origin acrylic acid currently (verify against https://access.trade.gov/ before invoicing). Section 301 List 3 25% additional duty applies on Chinese-origin acrylic acid (HS 291611). Major US domestic producers (verify each company-site pair against the producer's public website before relying): BASF Freeport Texas, Arkema Clear Lake Texas, Dow Chemical Deer Park Texas plus Texas City Texas.

The US acrylic acid lane is dominated by **ACGIH TLV 2 ppm with skin notation (no specific federal OSHA PEL) + TRI Form R + Section 301**. NO active US AD/CVD case. Major US producers: BASF Freeport Texas, Arkema Clear Lake Texas, Dow Chemical Deer Park + Texas City Texas.

Listing and threshold

Substance Acrylic acid (prop-2-enoic acid) (CAS 79-10-7), C3H4O2
Regime US Toxic Substances Control Act (TSCA), administered by EPA
Jurisdiction United States of America
Status Listed
Tonnage threshold CDR (Chemical Data Reporting) threshold: 25,000 lb (11,340 kg) manufactured or imported per site per year

Classifications under this regime

  • OSHA Hazard Communication Standard (HCS): GHS H226 / H302 / H312 / H314 / H332 / H400
  • OSHA has no specific federal PEL for acrylic acid in 29 CFR 1910.1000 Table Z-1; ACGIH TLV 2 ppm 8-hr TWA with skin notation is the practitioner-facing limit (verify against https://www.osha.gov/annotated-pels before relying)
  • NIOSH REL: 2 ppm 8-hr TWA (verify against https://www.cdc.gov/niosh/npg/)
  • NOT subject to TSCA Section 6 Risk Evaluation
  • NOT on DEA List I or List II
  • NOT on California Proposition 65 list (verify against OEHHA https://oehha.ca.gov/proposition-65/proposition-65-list before relying on negative listing)
  • **TRI Section 313 listed**
  • NOT on EPA RMP threshold list
  • DOT hazardous materials regulation: UN 2218, Class 8, PG II
  • IARC: nitric acid itself is not separately classified; occupational exposure to strong-inorganic-acid mists containing sulfuric acid was classified IARC Group 1 (laryngeal cancer) in Monograph Volume 54 (1992) (verify the current classification and Monograph volume against https://monographs.iarc.who.int/list-of-classifications before relying on the inorganic-acid-mist read-across for nitric acid)

Restrictions and conditions of use

  • OSHA-compliant SDS and workplace HazCom training required
  • **No specific federal OSHA PEL; ACGIH TLV 2 ppm + skin notation** drives workplace exposure-control overhead
  • NO active US AD/CVD case on Chinese-origin acrylic acid currently
  • Section 301 List 3 25% additional duty applies on Chinese-origin acrylic acid (HS 291611)
  • **TRI Form R annual reporting**

Importer obligations

TSCA is a self-certification regime. The dominant practitioner-facing layer is **ACGIH TLV 2 ppm with skin notation (no specific federal OSHA PEL) + TRI Form R + Section 301 + corrosion-resistant tankage for Skin Corr. 1A bulk handling**. NO active AD/CVD case. Major US producers: BASF Freeport Texas, Arkema Clear Lake Texas, Dow Chemical Deer Park Texas + Texas City Texas.

Required documents

  • TSCA Section 13 Import Certification statement on customs entry
  • OSHA-compliant SDS reflecting H226 / H302 / H312 / H314 / H332 / H400 classification
  • Customs entry CBP Form 7501 with HS code 291611 (acrylic acid) and Section 301 List 3 25% duty applied
  • TRI Form R annual report

Common compliance traps

The pitfalls that have bitten importers on this lane in the past. None of these is theoretical.

  • **No specific federal OSHA PEL; ACGIH TLV 2 ppm + skin notation** workplace exposure-control overhead
  • **TRI Form R annual reporting**
  • NO active US AD/CVD case
  • Section 301 List 3 25% additional duty applies
  • Major US producers: BASF Freeport Texas, Arkema Clear Lake Texas, Dow Chemical Deer Park + Texas City Texas
  • TBC inhibitor critical for storage
