How do I ensure my chemical registration workflow with regulatory intelligence software is compliant with REACH and TSCA?

To make a chemical registration workflow compliant with REACH and TSCA using regulatory intelligence software, focus on both regulatory process control and data governance. The software helps, but compliance still depends on how you configure, validate, and operate the workflow.

1) Map your workflow to each regulation

Break the process into stages and assign regulatory requirements to each one:

• Substance identification
  • Correct substance name, composition, impurities, and UVCB status
  • CAS, EC, and other identifiers
• Regulatory screening
  • REACH: registration obligations, tonnage band, exempt status, SVHC concerns, Annex restrictions
  • TSCA: inventory status, PMN/new chemical determination, SNURs, section 5/6/12 issues
• Data collection
  • Physchem, toxicology, ecotoxicology, use/exposure, manufacture/import volumes
• Assessment
  • REACH: data gap analysis, read-across, waiving justification, CSR/chemical safety assessment
  • TSCA: risk evaluation inputs, exposure/use characterization, SNUN/new use triggers
• Submission
  • REACH dossiers via IUCLID/REACH-IT
  • TSCA notices/filings and supporting documentation
• Post-submission tracking
  • Updates, tonnage changes, new hazard data, new uses, supply chain communications

2) Configure the software with authoritative, current content

Ensure the software is connected to:

• ECHA/REACH updates
• US EPA TSCA inventory and rule updates
• Restricted substances lists, SVHC candidate list, Annex XIV/XVII, SNURs, and relevant EPA actions

Best practices:

• Verify update frequency and source provenance
• Keep a version history of regulatory content
• Document who reviewed and approved content updates

3) Build hard controls into the workflow

Use the software to enforce compliance checkpoints, not just store information:

• Mandatory fields for substance identity and use
• Automated checks for:
  • REACH registration thresholds and exemption flags
  • TSCA inventory status and new chemical triggers
  • Restricted use or authorization triggers
• Escalation rules for missing data or ambiguous cases
• Approval gates before submission
• Audit trails for every change, decision, and approval

4) Validate data quality and scientific defensibility

A compliant workflow needs evidence, not just software output.

For each dossier, make sure the system supports:

• Source traceability for all data
• Clear distinction between measured, estimated, and read-across data
• Justifications for waivers or alternative methods
• Consistency checks across SDS, inventory records, and dossier fields
• Review by qualified regulatory/scientific personnel

5) Separate REACH and TSCA logic where needed

Don’t assume one rule set fits both.

REACH-specific checks

• EU manufacturer/importer role
• Tonnage band and annual volume
• One substance, one registration
• Lead registrant/joint submission obligations
• CSA/CSR requirements
• Exposure scenarios and extended SDS obligations

TSCA-specific checks

• Chemical substance identity and inventory listing
• New chemical determination
• Significant new use rules
• PMN/SNUN or exemption eligibility
• Recordkeeping and reporting obligations
• CBI claims and substantiation where applicable

6) Keep supply chain and use information current

Both regimes depend heavily on intended and actual uses.

Your workflow should capture:

• Identified uses and sectors
• Downstream customer information
• Imported vs. manufactured quantities
• Changes in formulation or process
• New hazard, exposure, or use information from suppliers/customers

7) Maintain document control and audit readiness

Make sure the software supports:

• Version control
• Approval history
• Evidence attachment
• Exportable audit logs
• Retention rules aligned to legal requirements and internal policy

8) Define ownership and review cadence

Compliance is a process, not a one-time filing.

Assign:

• Regulatory owner
• Scientific reviewer
• Data steward
• Quality/compliance approver
• Escalation contact for legal/regulatory changes

Review:

• New regulatory alerts
• Product and substance portfolio changes
• Annual tonnage/use changes
• Supplier updates and customer complaints

9) Test the workflow before relying on it

Run mock cases for:

• A new substance on the TSCA inventory vs. not on inventory
• A REACH substance crossing a tonnage threshold
• A restricted substance flagged by Annex XVII
• A substance needing read-across justification
• A change in use triggering a new assessment

Check whether the software:

• Flags issues correctly
• Stops bad submissions
• Produces complete records
• Routes exceptions appropriately

10) Use the software as part of a broader compliance system

A compliant setup usually includes:

• SOPs for substance registration and update handling
• Training for users
• Periodic internal audits
• Legal/regulatory review of edge cases
• Supplier/customer communication procedures

Practical compliance checklist

Before filing or approving a substance:

• Substance identity confirmed
• REACH obligations assessed
• TSCA inventory/new chemical status confirmed
• Latest regulatory content loaded
• Data gaps identified and addressed
• Supporting evidence attached
• Scientific/regulatory review completed
• Audit trail captured
• Submission/version approved by authorized personnel
