Navigating chemical shipments to the USA requires a comprehensive understanding of evolving regulations and compliance requirements. Recent tariff changes and enhanced regulatory scrutiny create new challenges for importers. Understanding how to import products to the USA while meeting all legal requirements becomes critical for business success. This complete guide covers essential compliance strategies for professional chemical importers.
Understanding the US Regulatory Framework
Toxic Substances Control Act (TSCA) Requirements
Imports of chemical substances, mixtures, or articles that contain a chemical substance or mixture must comply with the Toxic Substances Control Act (TSCA) to enter the U.S. Importers must certify that imported chemicals either comply with TSCA (positive certification) or, if not subject to TSCA requirements (negative certification).
TSCA regulation is important and has been beneficial to our health and the environment. The framework of the rule is simple: any novel chemical molecule must be vetted and approved through the EPA before it can be manufactured or imported. Non-compliance results in shipment detention and potential legal consequences.
A certification must be signed and filed electronically or in writing with CBP by the importer or an authorized agent of the importer. A certification must also include the certifier’s name, email address, and telephone number. Documentation accuracy ensures smooth customs clearance processes.
Environmental Protection Agency Oversight
The Environmental Protection Agency (EPA) established comprehensive regulations protecting human health and environmental safety. Chemical import oversight falls under EPA jurisdiction through TSCA enforcement. Compliance verification occurs at ports of entry nationwide. Violations result in shipment refusal and potential penalties.
Key EPA Requirements:
• Pre-manufacture notification for new chemicals
• Chemical inventory compliance verification • Safety data sheet documentation
• Environmental impact assessments
2025 Tariff Changes and Import Duties
Universal and Country-Specific Tariffs
The 10% duty went into effect on April 5 and the country-specific tariffs are effective on April 9, 2025. Both are imposed on most goods imported into the US, with narrow exceptions. These changes significantly impact chemical import costs and procurement strategies.
Even in the event that a product has a 0% general duty rate per its HTS code, you will still be responsible for the 10% tariff being applied to all goods from the EU as of April 9, 2025. Universal tariff application eliminates previous duty-free advantages for many chemicals.
Country-specific rates vary from 20% to 50% depending on origin. China faces some of the highest additional tariff rates. Strategic sourcing becomes essential for cost management. Alternative supply sources gain competitive advantages.
De Minimis Threshold and Entry Types
Any goods valued over $800 USD (de minimis value) are subject to import duty tax. However, items valued below $800 are exempt from duty, unless they fall under the De Minimis exception list. Chemical shipments rarely qualify for de minimis treatment due to value thresholds.
If your shipment is under $2,500, it qualifies for Entry Type 11. If it’s over $2,500, it must go through Entry Type 1. Either way, importers should be prepared for additional costs and regulatory steps. Entry type determination affects processing time and documentation requirements.
2025 Duty Structure:
| Value Range | Entry Type | Base Duty | Universal Tariff | Country-Specific | Total Potential |
| Under $800 | Informal | Varies | 10% | 0-50% | 10-60% |
| $800-$2,500 | Type 11 | Varies | 10% | 0-50% | 10-60% |
| Over $2,500 | Type 1 | Varies | 10% | 0-50% | 10-60% |
TSCA Certification Process
Positive vs. Negative Certification
The importer must submit a certification to CBP attesting that all chemicals in the shipment are either in compliance with TSCA (the affirmative certification) or that all chemicals in the shipment are not subject to TSCA (the negative certification). Certification type depends on chemical classification and intended use.
Positive certification confirms TSCA inventory listing or exemption qualification. Negative certification applies to excluded substances like foods, drugs, and cosmetics. Mixed shipments require careful evaluation of each component. Incorrect certification causes delays and potential penalties.
Electronic Filing Through ACE
The U.S. Customs and Border Protection (CBP) published a final rule on December 27, 2016, which establishes the option of filing TSCA import certification statements electronically through the Automated Commercial Environment (ACE). Electronic filing streamlines processing and reduces paperwork.
Digital submission enables real-time status tracking. Automated validation prevents common filing errors. Electronic records facilitate compliance audits. System integration improves overall efficiency.
Customs Broker Role in Certification
Typically, the customs broker makes the TSCA certification on behalf of importers. Professional brokers understand complex requirements and ensure accurate submissions. Expert guidance reduces compliance risks significantly. Established broker relationships facilitate smooth operations.
Required Documentation and Paperwork
Essential Import Documents
Commercial invoices must contain detailed chemical descriptions and values. Bills of lading establish shipping terms and responsibilities. Packing lists specify container contents and quantities. Safety data sheets provide hazard information.
A certificate of origin determines country-specific tariff rates. Import licenses may be required for controlled substances. Laboratory analysis reports verify product specifications. Quality certificates ensure regulatory compliance.
Chemical-Specific Documentation
Material Safety Data Sheets (MSDS) provide comprehensive hazard information. Chemical composition reports detail active ingredients and concentrations. Regulatory compliance certificates confirm safety approvals. Manufacturing certificates verify production standards.
Required Documentation Checklist:
• Commercial invoice with detailed descriptions
