The TSCA (Toxic Substances Control Act) Inventory is a database maintained by the EPA that lists over 86,000 chemicals used in the U.S., identified by CAS numbers. It categorizes substances as active (currently in commercial use) or inactive (not used commercially within specific periods). Businesses involved in manufacturing, importing, or processing chemicals must ensure compliance with TSCA rules to avoid penalties, which can reach $45,268 per day for violations.
Key compliance steps include verifying if a chemical is listed as active or inactive, submitting required notifications like Pre-Manufacture Notices (PMNs) or Chemical Data Reports (CDRs), and maintaining accurate records. Chemicals not listed on the inventory require EPA approval before commercial use. Additionally, companies must stay updated on regulatory changes, as the TSCA Inventory is updated biannually.
Non-compliance risks include supply chain disruptions, market exclusion, and EPA inspections. Partnering with experienced suppliers who provide regulatory documentation like Safety Data Sheets (SDS) and Certificates of Analysis (COAs) can simplify compliance efforts and reduce risks.

Key Parts of the TSCA Inventory
The TSCA Inventory classifies chemicals to determine the necessary steps for manufacturing, importing, or processing them.
Active vs. Inactive Substances
The EPA organizes substances on the TSCA Inventory into two main groups: active and inactive. This system, introduced through the Frank R. Lautenberg Chemical Safety for the 21st Century Act, plays a crucial role in how businesses handle chemicals in the U.S. market [1][2].
Active substances are those that were in commercial use between June 21, 2006, and June 21, 2016, according to a review finalized on October 5, 2018 [1][2][3]. These substances can be manufactured, imported, or processed without needing additional EPA notifications [2].
Inactive substances, on the other hand, were not in use during that 10-year period [3]. To reintroduce an inactive substance into commerce, companies must file a Notice of Activity (NOA) with the EPA. This requirement can extend lead times and complicate supply chain decisions, making it essential to verify a chemical’s status before moving forward.
The active/inactive classification directly influences supply chain planning and regulatory timelines. While businesses using active substances can proceed without delays, those working with inactive ones need to account for the extra steps required for EPA approval.
Confidential Business Information (CBI) and TSCA
Some chemicals on the TSCA Inventory are listed under Confidential Business Information (CBI) protections instead of their specific names. These entries might use generic terms like "alkyl compound" or "polymer" to safeguard proprietary information that could impact a company’s competitive position.
To secure CBI status, businesses must justify their claims, and the EPA reviews these requests to ensure a balance between protecting business interests and maintaining regulatory oversight and public safety.
For companies sourcing chemicals, dealing with CBI listings can be challenging. Verifying that confidential substances meet specific requirements often involves close coordination with suppliers and additional documentation. This extra effort is necessary to ensure compliance and proper identification when working with confidential entries.
Understanding the limitations of CBI is essential, especially since the TSCA Inventory is updated regularly, which can affect both public and confidential listings.
Recent TSCA Inventory Updates
The TSCA Inventory is updated frequently to reflect new chemical approvals, changes in classifications, and ongoing EPA reviews. These updates capture shifts in commercial use and regulatory decisions.
Changes such as status updates, CBI adjustments, or the addition of new chemicals are communicated through Federal Register notices and online updates. For businesses, staying informed about these changes is critical. For instance, a substance shifting from active to inactive status would require new notifications for future use, while newly added chemicals might open doors for product innovation.
To stay compliant and competitive, many companies implement regular review processes to monitor these updates. Tracking these changes helps businesses adapt their sourcing strategies, ensure regulatory compliance, and seize new opportunities for product development.

TSCA Reporting and Notification Requirements
If your company deals with chemicals in the United States, you need to comply with TSCA (Toxic Substances Control Act) reporting and notification rules. These regulations help the EPA track chemical usage and assess potential health and environmental risks.
Accurate reporting and timely notifications, based on the TSCA Inventory framework, are essential for staying compliant with these regulations.
Chemical Data Reporting (CDR) Requirements
The Chemical Data Reporting (CDR) rule requires manufacturers and importers to submit detailed information about chemicals produced or imported in quantities of 25,000 pounds or more per year at a single site. This reporting happens every four years, so it’s crucial to check the EPA’s latest guidelines for submission deadlines.
Reports must be submitted through the EPA’s e-CDRweb tool and should include details like production volumes, processing and use categories, and environmental releases. Companies also need to report worker exposure levels and the steps taken to reduce those exposures. Preparing these reports involves gathering accurate production data from manufacturing sites. This data helps the EPA prioritize chemicals for risk evaluations and regulatory decisions. Failure to comply with CDR requirements can lead to serious enforcement actions.
Significant New Use Rules (SNURs)
Significant New Use Rules (SNURs) come into play when the EPA identifies potential risks linked to new applications of a chemical. If your company plans to use a chemical in a way that differs from its traditional use, you must submit a Significant New Use Notice (SNUN) at least 90 days before starting the new application. The EPA will review the notice and may request more information, extend the review period, or impose restrictions on the proposed use.
SNURs can apply to scenarios like increased production volumes, new applications, alternative processing methods, or changes to worker safety measures. Since the 90-day review period could impact product development timelines, it’s important to plan accordingly.
Pre-Manufacture Notices (PMNs)
If you’re planning to manufacture or import a chemical not listed on the TSCA Inventory, you’ll need to file a Pre-Manufacture Notice (PMN) at least 90 days before beginning commercial activities. This rule applies to both brand-new chemical substances and existing chemicals entering the U.S. market for the first time.
A PMN must include detailed information such as the chemical’s identity, production volume, intended uses, exposure potential, and any known health or environmental effects. Companies are also expected to provide data on worker safety measures and environmental release controls. The EPA reviews this information to determine whether the chemical can be used without restrictions, requires conditions under a consent order, or needs further regulation through a significant new use rule. If the risks are deemed too high, the EPA may restrict or ban the chemical altogether.
Preparing a PMN often requires extensive resources, including toxicity testing, exposure modeling, and risk assessments. Many companies opt for pre-submission meetings with the EPA to clarify requirements and avoid delays or additional information requests.

How to Achieve TSCA Inventory Compliance
Meeting TSCA compliance involves verifying your chemicals, submitting necessary documentation, and keeping up with regulatory updates. This process requires careful attention to EPA guidelines and deadlines, as well as a structured approach to ensure everything is in order.
Checking Chemical Status on the TSCA Inventory
The first step is to verify whether your chemicals are listed on the EPA’s TSCA Inventory. This inventory, which is publicly accessible online, includes over 86,000 chemicals. As of the July 2025 update, it lists 86,862 substances, with 42,578 marked as active[4][5].
While the public TSCA Inventory is updated every six months, it does not include chemicals with identities protected as Confidential Business Information (CBI). For full details, consult the EPA’s internal TSCA Master Inventory File, which is continuously updated and includes these confidential listings[4].
Pay close attention to inventory flags. These flags highlight substances with manufacturing or use restrictions, as well as those partially or fully exempt from TSCA reporting requirements[4][5]. Chemicals not listed on the inventory are classified as "new chemical substances", which typically require a Premanufacture Notice (PMN) before they can be manufactured or imported commercially[4].
Once you’ve confirmed your chemical’s status, you can move on to submitting the necessary notifications.
Submitting Notifications and Documentation
After verifying your chemical’s status, the next step is to complete any required notifications and maintain proper records. The type of submission depends on whether you’re dealing with a new chemical, a significant new use, or routine reporting requirements.
For chemicals not listed on the TSCA Inventory, a PMN must be submitted before any commercial activity begins. This notice should include detailed information about the chemical, such as its identity, production volumes, intended uses, and any known health or environmental risks.
Maintaining organized records is crucial. A centralized system to track submission dates, EPA responses, and any imposed conditions or restrictions can simplify compliance audits.
If you work with specialty chemical suppliers, partnering with experienced providers can make this process smoother. For example, Allan Chemical Corporation, with decades of experience in regulated industries, offers regulatory documentation like Certificates of Analysis and Safety Data Sheets to support TSCA compliance efforts.
After submission, focus on maintaining compliance as regulations evolve.
Maintaining Compliance Over Time
Compliance with TSCA regulations isn’t a one-time task – it requires ongoing effort. The EPA frequently updates rules, guidance documents, and inventory listings, so staying current is essential.
Set up a regular review schedule to ensure your chemical inventory aligns with the latest TSCA requirements. This includes checking for newly added chemicals, reviewing changes to existing flags or restrictions, and confirming that your reporting obligations are up to date. Since the non-confidential portion of the inventory is updated roughly every six months, aligning your review schedule with these updates is a practical approach[5].
To stay informed, subscribe to EPA notifications and collaborate with industry associations that monitor TSCA developments. Pay attention to new Significant New Use Rules (SNURs) that could impact your operations and establish internal alerts for key compliance deadlines.
Annual audits are another important tool for maintaining compliance. These reviews help identify gaps in your procedures or documentation before they become larger issues. Use the inventory guidelines mentioned earlier as a reference during these audits.

Summary and Key Points
Navigating TSCA inventory compliance doesn’t have to feel overwhelming. Staying organized, keeping accurate records, and collaborating with knowledgeable suppliers can make the process much smoother.
TSCA Compliance Basics
Inventory verification is the cornerstone of TSCA compliance. The TSCA Inventory classifies thousands of chemicals as either active or inactive. Before engaging in any commercial activity, it’s crucial to confirm the chemical’s status – whether it’s new, existing, active, or inactive.
Reporting obligations depend on your chemical activities and production volumes. Under the Chemical Data Reporting (CDR) rule, manufacturers are required to report every four years. The next reporting period is in 2028, covering production data from 2024 to 2027 [8]. Reporting thresholds differ based on the specific substance and activity [8].
Import certifications are a non-negotiable step. All chemical imports must be certified through the ACE system [7]. Depending on the situation, you’ll need to submit either a positive certification (confirming TSCA compliance) or a negative certification (stating the chemical isn’t subject to TSCA). This requirement applies to every shipment, regardless of size or frequency.
Record maintenance is an ongoing responsibility. Beyond initial compliance, you’ll need to retain records as specified by TSCA. Establishing strong internal processes and leveraging external expertise can simplify this task significantly.
