Why TSCA PBT Section 6(h) Supplier Declarations Matter
If your company imports, distributes, or assembles products containing components regulated under TSCA Section 6(h), you're responsible for knowing whether they contain any of the five listed PBT (Persistent, Bioaccumulative, and Toxic) substances. The EPA does not just target chemical manufacturers—you, as the downstream user or importer, must demonstrate due diligence.
Collecting accurate supplier declarations is your first line of defense in proving compliance.
What to Ask Suppliers
Whether you're dealing with cables, circuit boards, plastics, or rubber components, your supplier outreach should capture the following:
- Presence of TSCA PBT substances (Yes / No / Unknown)
- Chemical name (e.g., PIP 3:1, DecaBDE, HCBD)
- CAS number
- Concentration and intended function
- Exemption applied, if any
- Country of origin (particularly for REE or PIP 3:1-related scrutiny)
- Supporting documentation:
- Safety Data Sheets (SDS)
- Full Material Disclosures (FMD)
- Certificates of Compliance (CoC)
- IPC-1752A XML declarations (if available)
The more structured your request, the better your supplier response rate.
TSCA Section 6(h) Declaration Formats
For data collection, consider the following hierarchy of formats:
- Preferred: IPC-1752A XML format
- Acceptable: Pre-formatted Excel or PDF with:
- Supplier name and part number
- Internal item number
- PBT chemical presence (Yes / No / Unknown)
- Chemical name + CAS number
- Declaration date
- Signature or digital acknowledgment
Always include a unique declaration ID and date to track versions.
Supplier Engagement Tips
Getting declarations isn’t just about the form—it’s about how you ask.
Here’s how to improve your response rate:
- Pre-fill known data (e.g., part numbers, CAS #) to reduce their workload
- Set clear deadlines and follow-up reminders
- Explain the regulatory context (TSCA fines, shipment blocks, contract risk)
- Provide training or documentation links to support suppliers
- Use a portal where suppliers can upload declarations and track status
If your suppliers don’t understand the why, they’re less likely to comply.
What to Do With the Responses
Once you start collecting data:
- Store everything in a centralized compliance folder or platform
- Tag declarations by item, part number, or material group
- Flag any "Unknown" or missing data for escalation
- Update your BOM approvals and material master data accordingly
Regulators and customers expect audit-ready evidence—not just informal confirmations.
Tools to Automate TSCA PBT Section 6(h)
If you're managing hundreds or thousands of parts, manual collection won't scale.
Recommended tools:
- Acquis – Automates declaration collection and compliance tracking
- BOM Intelligence tools – Scan and flag BOMs for PBT chemicals
- Supplier portals – Let vendors submit documents, track status, and view approvals
- ERP/PLM integration – Ensure real-time updates to product compliance status
Don’t let outdated spreadsheets become your compliance bottleneck.
