Historical deadline correction, 9 October 2026: The deadline known on this article’s preserved 14 September 2020 date was 30 November 2020. EPA announced a further extension on 19 November to 29 January 2021. References below to November 30 describe the earlier planning deadline, not the final close or a current filing date. This correction also addresses 2020 reporting applicability, reporting-year scope and importer-site definitions using the September 2020 EPA instructions. The separate import-certification and PMN statements below are also qualified against the historical regulations. Remaining enforcement examples are not verified by this correction.
As at September 14, 2020, the TSCA Chemical Data Reporting deadline was November 30. EPA had extended the original September 30 deadline by two months alongside revised requirements and an updated reporting tool. For that historical cycle, importers needed to check the applicable thresholds, substance and activity scope, and exemptions before determining whether reporting was required. The penalty structure for missing this date is not something you want to discover after the fact: civil penalties under TSCA Section 16. The January 2020 inflation adjustment set a $40,576 maximum under 15 USC 2615(a)(1) for the applicable assessment period; the violation and assessment dates determine the applicable schedule.
You Are Treated as a Manufacturer Even If You Do Not Make Anything
The Chemical Data Reporting rule runs under TSCA Section 8(a). Most people in chemical manufacturing already know it. What catches importers off guard is that TSCA treats importers as manufacturers for CDR purposes. If you are a US company importing a chemical substance that appears on the TSCA Inventory, you are a manufacturer under the statute. Importers must assess CDR applicability, including site, volume and exemptions; Inventory listing alone does not establish a filing obligation.
CDR provides production and import information for chemical risk assessment. The 2020 cycle covers 2016 through 2019. The former reference to an active list of 7,600 automatically reportable substances is withdrawn: applicability requires the Inventory, threshold and exemption checks described in the dated instructions.
The submission portal is EPA’s CDX (Central Data Exchange), using the e-CDRweb reporting tool. If you have never set up a CDX account and you are sitting here with a November 30 deadline, start the account registration process today. EPA’s identity verification steps take time and they will not make an exception because you left it late.
How to Calculate Whether Your Volumes Trigger the Obligation
For the 2020 cycle, test whether combined domestic manufacture and imports of a reportable substance reached 25,000 pounds at one reporting site in any year from 2016 through 2019. Exemptions and the lower threshold must also be checked. The table is a volume comparison only, not a reporting determination.
| Import Volume | Metric Tonnes | Pounds | At least 25,000 lb? | Applicability decision |
|---|---|---|---|---|
| Small volume | 5 MT | ~11,023 lbs | No | Needs applicability review |
| Near threshold | 9 MT | ~19,842 lbs | No | Needs applicability review |
| Just over | 12 MT | ~26,455 lbs | Yes | Needs applicability review |
| Typical commercial | 20 MT | ~44,092 lbs | Yes | Needs applicability review |
| High volume | 50 MT | ~110,231 lbs | Yes | Needs applicability review |
In an illustrative Ohio example, imports of 15 metric tonnes in 2018 and 14 metric tonnes in 2019 are approximately 33,069 and 30,865 pounds. These volumes meet the standard volume test; exemptions and the correct reporting site still require review. For a reportable substance, the 2020 submission covers annual volumes for 2016–2019, with additional required information for principal year 2019.
The 2,500-pound threshold depends on listed TSCA actions, not a generic high-concern or PBT label. Check section 2.2.2 of the 2020 instructions against the substance’s status on 1 June 2020: specified rules under sections 5(a)(2), 5(b)(4) or 6; orders under sections 4, 5(e) or 5(f); or granted civil relief under sections 5 or 7.
Count manufacture, including imports, of the same substance at the reporting site in each year. Imported quantity is not limited to what the importer later uses itself. For example, importing 20 tonnes and reselling 12 still leaves 20 tonnes of imports to assess, together with any domestic manufacture at that site.
What You Need to Gather Before You Can File
CDR requires more than a volume number. The reporting structure covers several data categories, and gathering them takes time that most companies seriously underestimate.
Gather annual domestic manufacture and import volumes for 2016–2019 for each substance being assessed. For reportable substances, principal-year 2019 information and any applicable partial exemptions require separate review. Confirm chemical identities against the instructions rather than relying on a trade name alone.
For importers, the reporting site is the operating unit controlling the import transaction, not necessarily the receiving warehouse. Where no such US unit or headquarters exists, the instructions specify the address of a US agent authorised to accept service of process for the importer. Follow section 4.4.1.1 for the site information to report.
Processing and use details for principal year 2019 depend on the applicable reporting requirements and partial exemptions. Use the prescribed categories where required.
Exposure-related information is also subject to the applicable reporting requirements. Section 4.2 applies the known or reasonably ascertainable standard, including reasonable inquiry; missing information is not an automatic exemption.
What the Penalty Structure Actually Looks Like in Practice
TSCA Section 15 violations are subject to the civil penalty provisions in Section 16. The January 2020 schedule listed $40,576 under 15 USC 2615(a)(1), with later inflation adjustments; it is not a timeless maximum. EPA has discretion in penalty calculation based on gravity, good faith, compliance history, and ability to pay. But it sets the scale of your exposure clearly.
A company that failed to file CDR for three chemical substances across four reporting years, and that failure ran 60 days past the deadline, is theoretically looking at penalty exposure in the millions before any mitigation factors are applied. EPA does not routinely pursue maximum penalties for first-time filers with no history of violations, but the agency increased its TSCA enforcement activity significantly after the 2016 TSCA reform legislation. Do not assume the environment is as relaxed as it was five years ago.
What actually triggers an audit? The EPA can identify non-filers by cross-referencing CBP import data with CDR submissions. If your company appears as an importer of a specific chemical substance in customs records but has no corresponding CDR filing, that discrepancy is visible to the agency. Tips also come in from competitors and industry groups. Assuming non-compliance is invisible because EPA has limited enforcement resources is not a compliance strategy.
Do not treat an intentionally incomplete filing as compliant. Follow the applicable reporting standard, certification and correction procedures; seek qualified assistance for missing information. This historical article does not establish a current deadline or promise favourable enforcement treatment.
The Common Compliance Gaps That Keep Showing Up for China Importers
Count the full imported amount, not only internal consumption, together with domestic manufacture of the same substance at the reporting site. Assess each year separately against the applicable threshold and exemptions.
Misidentifying a chemical under the wrong CAS number is a real risk when you are importing substances described in Chinese trade documentation with transliterated names or IUPAC nomenclature variants. Always confirm the correct CAS number through your supplier’s safety data sheet, cross-reference against the TSCA Inventory, and document that verification.
For subsidiaries and affiliates, identify the responsible reporting company and controlling reporting site under the 2020 instructions. Review each relevant entity’s manufacture and imports, applicable thresholds and exemptions. Two entities exceeding a volume figure alone does not establish two filing obligations.
The Broader TSCA Obligations That Do Not Go Away After November 30
TSCA CDR reporting is the immediate deadline, but it sits alongside ongoing obligations that importers of Chinese chemicals carry all year round.
Under 19 CFR 12.121, April 2020 edition, covered TSCA chemicals in bulk or mixtures require positive import certification. TSCA-excluded chemicals require negative certification when not clearly identified as excluded. Chemicals within articles require certification only where a specific TSCA rule or order requires it. The applicable conditions matter; certification is not universal for every chemical-containing import.
For a new chemical, assess the historical PMN exclusions in 40 CFR 720.30 and the applicable section 5 notification and review requirements before commercial import. Non-exempt new-chemical imports require that process; not every unlisted substance automatically requires a PMN. Establish the actual Inventory status and applicable exemption conditions rather than treating a missing public search result as conclusive.
For the historical 2020 cycle, substances meeting an applicable threshold in any year from 2016 through 2019 required an applicability review, including exemptions. November 30 was the earlier planning deadline; the final close was extended to 29 January 2021. Maintain substance, site and annual-volume records for future cycles and check the instructions applicable to each cycle.
