What are TSCA CDR Reporting Thresholds?

Definition

TSCA CDR Reporting Thresholds determine when a manufacturer or importer must report chemical production information to the U.S. Environmental Protection Agency (EPA) under the Chemical Data Reporting (CDR) rule. For most reportable chemical substances, the threshold is 25,000 pounds or more at a single site during any calendar year in the reporting period. A reduced threshold of 2,500 pounds applies to chemical substances subject to certain specified TSCA actions. :contentReference[oaicite:0]{index=0}

The threshold is based on the amount manufactured, including imported, for commercial purposes at a site. It is not determined by the chemical's hazard level or by combining production volumes from unrelated sites. Companies must also check whether the chemical is on the TSCA Inventory and whether an exemption applies before concluding that a threshold creates a reporting obligation. :contentReference[oaicite:1]{index=1}

How the Thresholds Work

For the 2024 CDR cycle, companies evaluated production during calendar years 2020, 2021, 2022, and 2023. A chemical generally became subject to reporting when its production volume reached the applicable threshold at a single site during any of those years. The principal reporting year for that cycle was 2023, while earlier years were used primarily to determine production-volume history. :contentReference[oaicite:2]{index=2}

  • 25,000-pound threshold: Applies generally to reportable chemicals that are not subject to the specified TSCA actions triggering the lower threshold.
  • 2,500-pound threshold: Applies to chemicals subject to certain TSCA sections 5 or 6 rules, certain sections 4, 5(e), or 5(f) orders, and specified civil-action relief.
  • Single-site measurement: Production and imports are evaluated at each applicable U.S. site rather than simply adding unrelated site volumes together.
  • Inventory and exemptions: Meeting a volume threshold does not by itself establish an obligation when the substance or manufacturer qualifies for an applicable exemption.

Calculating Production Volume

Production volume includes domestic manufacturing and importing of the same chemical substance at the applicable site. When both activities occur, the amounts are added together for that site and calendar year when testing the threshold. For mixtures, companies may need to evaluate the amount of each constituent chemical rather than treating the entire mixture as one chemical substance. :contentReference[oaicite:3]{index=3}

For example, if a site manufactures 18,000 pounds of a chemical and imports another 9,000 pounds of that same chemical during one calendar year, the combined production volume is 27,000 pounds. That exceeds the general 25,000-pound threshold, assuming the chemical is otherwise subject to CDR and no applicable exemption applies.

The same calculation changes when a chemical is subject to the reduced threshold. A site producing 2,700 pounds of a chemical subject to the specified TSCA actions would exceed the 2,500-pound threshold and generally trigger CDR consideration. :contentReference[oaicite:4]{index=4}

Special Thresholds and Regulatory Status

The 2,500-pound threshold is tied to particular TSCA actions rather than simply to a company's classification of a chemical as hazardous. EPA guidance identifies specified rules and orders under TSCA sections 4, 5, and 6, along with certain civil-action relief, as circumstances that can trigger the reduced threshold. A section 4 test rule alone, for example, does not automatically create the reduced threshold. :contentReference[oaicite:5]{index=5}

Regulatory status must therefore be checked for the applicable reporting cycle. EPA's chemical status information identifies substances subject to the lower threshold, helping reporters distinguish ordinary 25,000-pound requirements from the 2,500-pound requirement. This threshold review can be incorporated into a Flexible Workflow so teams can configure approval steps and thresholds around their compliance review process.

Thresholds in Finance and Compliance Operations

Although CDR is an environmental reporting requirement, threshold monitoring can affect accounting operations, purchasing records, inventory data, and compliance controls. Production and import quantities may originate in different operational systems, so finance and compliance teams benefit from clear ownership of source data and documented review controls.

An audit trail helps connect reported quantities and approval decisions with underlying accounting records, supporting auditability and consistent reporting controls. Similarly, Actuals Reporting can help teams distinguish recorded production or purchasing activity from forecasts when reviewing historical volumes used in compliance analysis.

Threshold governance can also be aligned with Adjustment Thresholds, particularly where finance teams define separate approval or review levels for corrections to operational and reporting data. For management reporting, Codm Reporting can provide another reference point for organizing data and maintaining consistent reporting structures across business units.

TSCA CDR thresholds should not be confused with tax thresholds. For example, an Economic Nexus Threshold concerns when economic activity may create sales or use tax obligations in a jurisdiction, whereas CDR thresholds concern chemical production or import volumes under TSCA.

Separate tax controls can include Identification And Reporting Of Tax Mismatch for identifying line-item tax differences. Teams reviewing chemical-related transactions may also need to validate sales tax treatment independently from environmental reporting requirements.

At the transaction level, accurate gl coding can help connect invoices, purchases, inventory movements, and other financial records to the accounts used for reporting. Where these workflows operate through an ERP, organizations may use netsuite or another ERP environment to maintain consistent data structures and integration controls.

Workflow and Reporting Applications

Threshold monitoring becomes more useful when operational data, compliance reviews, and financial reporting follow consistent approval rules. Agentic AI for Accrual Approval Workflows can support policy-driven approval workflows that are customized by business unit, department, and thresholds, while Accruals Discovery For Goods Recieved can support identification of goods received but not yet invoiced for timely expense recognition and invoice matching.

These processes can complement CDR data governance by helping teams maintain reliable transaction records that feed financial reporting. They should remain distinct from the regulatory determination itself: the applicable TSCA threshold, chemical status, site production volume, and exemptions must be evaluated against the governing CDR requirements.

Summary

TSCA CDR reporting generally uses a 25,000-pound annual production threshold at a single site, with a 2,500-pound threshold for chemical substances subject to specified TSCA actions. Manufacturers and importers should evaluate production and import quantities by site and calendar year, verify the chemical's regulatory status, and check applicable exemptions. :contentReference[oaicite:6]{index=6}

For the next CDR cycle, EPA states that the 2028 submission period will run from June 1, 2028, through September 30, 2028, with 2027 as the principal reporting year and 2024 through 2027 as the production-volume period to consider. :contentReference[oaicite:7]{index=7}
