Implementation deadlines create immediate compliance pressures for companies with pending submissions. Training programs help internal teams understand revised requirements and submission protocols. Legal teams review existing compliance programs against updated regulatory standards.
Key Compliance Obligations Overview
Current TSCA requirements encompass multiple sections creating comprehensive regulatory coverage:
TSCA Section | Requirement | Compliance Timeline | Key Obligations |
Section 5 | New Chemical Review | Before manufacture/import | PMN, SNUN submissions |
Section 8(a) | Reporting Requirements | Ongoing | Chemical inventory reporting |
Section 8(b) | Inventory Maintenance | Continuous | Chemical substance listing |
Section 13 | Import Certification | Every shipment | Positive/negative certification |
Manufacturers and importers must maintain current knowledge of regulatory status for all chemical substances. Documentation requirements extend throughout the supply chain affecting procurement and quality assurance processes. Compliance monitoring systems track regulatory changes and implementation deadlines continuously.
What Chemicals Are Subject to TSCA

TSCA coverage extends to most chemical substances manufactured or imported for commercial purposes in the United States. Understanding coverage boundaries helps companies determine applicable compliance requirements for specific products. The chemical substance inventory serves as the primary reference for regulatory status determination.
TSCA Chemical Substance Inventory
Section 8(b) of the Toxic Substances Control Act requires EPA to compile, keep current, and publish a list of each chemical substance that is manufactured or processed in the United States for TSCA uses. The inventory contains over 86,000 chemical substances with regular updates reflecting commercial activity. Chemicals listed on the inventory qualify as “existing” substances with different regulatory requirements than new chemicals.
Inventory searches require accurate chemical identification using CAS numbers or chemical names. Companies must verify inventory status before manufacturing or importing any chemical substance. Confidential business information protections affect inventory transparency for certain proprietary chemicals.
The inventory determines whether chemicals require premanufacture notification or qualify for existing chemical status. Regular inventory updates reflect changes in commercial chemical usage patterns. Companies monitor inventory additions affecting their product portfolios and regulatory obligations.
Exemptions and Exclusions
Several chemical categories receive exemptions or exclusions from standard TSCA requirements:
• Pesticides: Regulated under FIFRA rather than TSCA for pesticidal uses
• Food Additives: FDA jurisdiction for food contact and additive applications
• Cosmetic Ingredients: Limited TSCA coverage for cosmetic-specific uses
• Tobacco Products: Excluded from TSCA regulatory coverage
• Nuclear Materials: Atomic Energy Act provides separate regulatory framework
The section 13 rule requires importers of chemicals not subject to TSCA (e.g., pesticides) to certify that compliance with TSCA is not required. Mixed-use chemicals may require TSCA compliance for some applications while receiving exemptions for others. Companies must understand use-specific regulatory requirements for multi-purpose chemicals.
New Chemical Substances vs. Existing Chemicals
New chemical substances not listed on the TSCA inventory require premanufacture notification before commercial introduction. Existing chemicals benefit from simplified regulatory pathways with established safety profiles. The distinction affects submission requirements, review timelines, and commercial introduction strategies.
Significant new use rules (SNURs) apply to certain existing chemicals used in new applications or production volumes. Companies must evaluate SNUR applicability before expanding chemical uses beyond historical patterns. Notification requirements vary based on chemical identity and intended use patterns.
TSCA Import Certification Process
Import certification represents a critical compliance requirement for all chemical shipments entering the United States. The certification process ensures regulatory compliance while facilitating legitimate trade in chemical substances. Proper certification prevents customs delays and regulatory violations affecting business operations.
Section 13 Certification Requirements
Under U.S. Customs and Border Protection regulations, importers are required to certify that imported chemicals either comply with TSCA (positive certification) or, if they are not clearly identified as excluded from TSCA, are not subject to TSCA (negative certification). Every chemical shipment requires appropriate certification regardless of volume or value.
This checklist provides help for chemical importers to determine how to certify their chemical imports in order to comply with the regulatory requirements under section 13 of the Toxic Substances Control Act. The certification process involves several key steps requiring careful attention to detail and regulatory compliance.
A certification must be signed and filed electronically or in writing with CBP by the importer or an authorized agent of the importer. Electronic filing through automated commercial environment (ACE) systems streamlines the certification process. Written certifications require specific language and format compliance for acceptance.
Positive vs. Negative Certification
Certification types depend on whether chemicals fall under TSCA jurisdiction and compliance status:
Certification Type | When Required | Statement Required | Documentation Needed |
Positive | Chemical subject to TSCA and compliant | “I certify that all chemicals comply with TSCA” | PMN clearance, inventory status |
Negative | Chemical not subject to TSCA | “I certify chemicals are not subject to TSCA” | Exemption documentation |
Conditional | Mixed shipments | Specific chemical-by-chemical certification | Detailed product breakdown |
Positive certification requires verification that chemicals comply with all applicable TSCA requirements including PMN submissions and significant new use restrictions. Negative certification applies to exempt chemicals like pesticides and food additives under other regulatory frameworks. Mixed shipments containing both TSCA and non-TSCA chemicals require careful documentation and certification.
Documentation and Filing Procedures
Import documentation must include accurate chemical identification, regulatory status verification, and appropriate certification statements. Electronic filing systems require specific data formats and validation procedures for acceptance. Customs brokers often handle certification filing on behalf of importers requiring clear communication of regulatory requirements.
Record-keeping obligations extend beyond the import transaction to include ongoing compliance monitoring. Documentation retention periods vary by chemical type and regulatory section requirements. Audit trails must demonstrate compliance decision-making processes and supporting evidence.
Recent Regulatory Changes Affecting Compliance
The 2024-2025 regulatory period brings substantial changes to TSCA implementation affecting multiple chemical categories and compliance procedures. EPA resource constraints delay some initiatives while accelerating others based on public health priorities. Companies must track regulatory changes continuously to maintain compliance across evolving requirements.
PFAS and PBT Chemical Restrictions
The amendments to TSCA chemicals regulations render new PFAS and other PBT chemicals ineligible for certain exemptions from the premanufacture review process. Enhanced scrutiny applies to persistent, bioaccumulative, and toxic substances across all regulatory pathways. Companies manufacturing or importing PFAS face significantly increased compliance burdens and submission requirements.
The reporting period was scheduled to begin on November 12, 2024, but the final rule delays the beginning of the reporting period until July 2025 due to budgetary constraints. PFAS reporting requirements affect manufacturers and importers of fluorinated chemicals across multiple industry sectors. Comprehensive chemical inventory reviews identify PFAS substances requiring regulatory reporting.
EPA’s TSCA program has had resource constraints for years, which has delayed a number of important efforts affecting regulatory timeline predictability. Companies plan compliance activities around uncertain regulatory schedules. Resource limitations affect EPA’s ability to process submissions and provide timely guidance.
Enhanced Data Requirements
In the December 2024 final rule, updates were made to the information requirements at 40 CFR 720.45. Specifically, EPA amended the text at 720.45 to clarify the level of detail expected for the information submitters are required to provide in new chemicals notices whenever those data are known to the submitter or reasonably ascertainable.
The enhanced requirements affect submission quality and review timelines for new chemical applications. Companies invest additional resources in data generation and compilation for regulatory submissions. Technical expertise requirements increase for preparing compliant submissions under revised standards.
Documentation standards require more comprehensive chemical characterization and exposure assessment information. Testing protocols must align with EPA expectations for data quality and relevance. Submission review times may extend as EPA evaluates enhanced data packages against safety standards.
