Exporting chemicals from Latin America to the US requires TSCA compliance, correct HTS classification, and a customs bond—but with the right partner, it’s manageable

Exporting chemicals from Latin America to the United States involves navigating a complex web of federal regulations, customs procedures, and supply chain logistics. The first and most critical step is determining whether your chemical substance is listed on the Toxic Substances Control Act (TSCA) Inventory, administered by the U.S. Environmental Protection Agency (EPA). If your chemical is not on the inventory, you must submit a Premanufacture Notice (PMN) at least 90 days before export. For existing chemicals, you still need to comply with EPA reporting under the Chemical Data Reporting (CDR) rule if volumes exceed 25,000 pounds per year. Additionally, the U.S. Customs and Border Protection (CBP) requires importers to file an entry summary with a surety bond, and the Harmonized Tariff Schedule (HTS) code for chemicals typically falls under Chapter 28 (inorganic) or Chapter 29 (organic). Duty rates vary widely: for example, many inorganic chemicals enter duty-free under Most Favored Nation (MFN) status, while certain organic compounds may face rates between 3.7% and 6.5%. Understanding these specifics is essential to avoid costly delays or penalties.

Regulatory Compliance Beyond TSCA

Beyond TSCA, chemical exports may fall under additional EPA programs such as the Significant New Alternatives Policy (SNAP) for ozone-depleting substances, or the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) if the chemical is used as a pesticide. The Occupational Safety and Health Administration (OSHA) also mandates that all chemical shipments include a Safety Data Sheet (SDS) compliant with the Globally Harmonized System (GHS) of classification and labeling. The SDS must be in English and include sections on physical hazards, health effects, and emergency response. For chemicals classified as hazardous materials, the Department of Transportation (DOT) enforces strict packaging, marking, labeling, and placarding requirements under 49 CFR Parts 171-180. Failing to comply with these regulations can result in fines up to $75,000 per violation per day, and the shipment may be seized or rejected at the port of entry.

Logistics and Documentation Essentials

Shipping chemicals from Latin America to the US typically occurs via ocean freight in ISO tanks, drums, or intermediate bulk containers (IBCs). The Bill of Lading must accurately describe the chemical composition and hazard class. A commercial invoice, packing list, and certificate of origin (often under USMCA or other free trade agreements) are required to claim preferential duty rates. For example, chemicals produced in Mexico may qualify for duty-free entry under the United States-Mexico-Canada Agreement (USMCA) if they meet the rule of origin. However, many Latin American countries, such as Brazil, Argentina, and Colombia, do not have bilateral free trade agreements with the US, so MFN rates apply. The importer of record must obtain a customs bond—typically continuous bonds start at around $50,000 for low-risk shipments—and may need to file an Importer Security Filing (ISF) at least 24 hours before loading. Working with a licensed customs broker who specializes in chemical imports is strongly recommended.

Country-Specific Considerations in Latin America

Exporting from different Latin American countries presents unique challenges. In Brazil, the National Health Surveillance Agency (ANVISA) requires prior registration for certain chemical products, and the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA) may impose export licensing for hazardous substances. In Mexico, the Comisión Federal para la Protección contra Riesgos Sanitarios (COFEPRIS) regulates chemical exports, and the Secretaría de Economía manages tariff and non-tariff barriers. In Colombia, the Instituto Colombiano Agropecuario (ICA) controls agrochemical exports, while the Ministry of Environment oversees industrial chemicals. Exporters must also comply with their own country's export control laws, such as Brazil's INMETRO certification for product safety. These layers of regulation mean that a single shipment can involve multiple government agencies on both sides of the border, making early coordination essential.

Common Mistakes and How to Avoid Them

One frequent error is misclassifying the HTS code, which can lead to incorrect duty payments or even penalties. For example, a chemical that is actually a mixture may be classified under a different chapter than its pure components. Another mistake is assuming that a chemical is exempt from TSCA because it is a natural substance—many naturally derived chemicals still require EPA review if they are chemically modified. Exporters also often overlook the need for a US-based agent for EPA correspondence, or fail to renew their TSCA certifications annually. To avoid these pitfalls, maintain a compliance checklist that includes: verifying TSCA inventory status, securing a customs bond, obtaining correct HTS codes, preparing GHS-compliant labels and SDS, and confirming that the carrier is authorized to transport hazardous materials. Regular training for logistics staff and a pre-shipment audit by a trade compliance specialist can save significant time and money.
