Why Wait for a Problem You Can Engineer Out?
In TSCA Section 6(h), the EPA doesn’t just restrict PBT substances it creates a compliance burden that’s entirely avoidable with the right design practices. If your engineers are specifying materials or sourcing parts without chemical screening, you’re not just increasing risk you’re baking noncompliance into the product.
Let's learn how proactive product design choices can help manufacturers avoid the top five TSCA-restricted PBTs before they ever enter the BOM.
- Step 1: Understand the High-Risk Use Cases
TSCA’s five restricted substances—PIP (3:1), DecaBDE, PCTP, HCBD, and 2,4,6-TTBP—appear in common use cases:
- PIP (3:1): Cable jacketing, circuit board laminates, industrial connectors
- DecaBDE: Flame-retardant plastics in housings, enclosures, auto parts
- PCTP: Rubber seals, gaskets, hoses
- HCBD: Byproduct in chlorinated solvent production; trace presence in pigments
- 2,4,6-TTBP: Fuel additives, greases, antioxidants in lubricants
Knowing where these show up helps teams screen effectively at the design stage
- Build a Design-for-Compliance Mindset
- Loop compliance into engineering change requests (ECRs)
- Add TSCA PBT CAS screening into approved part sourcing tools
- Create supplier onboarding criteria that require chemical-level disclosure
- Mandate alternatives analysis when high-risk categories are involved
When compliance is part of design not just a post-launch headache everything downstream moves faster.
- Choose Verified Low-Risk Materials
For many TSCA PBT risks, there are proven substitutes:
- Use halogen-free flame retardants instead of DecaBDE
- Switch to non-phthalate flexible polymers in wire insulation
- Source EPDM or silicone rubber compounds that are free of PCTP
- Confirm pigment suppliers follow EPA clean production standards
Design engineers don’t need to memorize the TSCA rule—but they do need systems that flag high-risk categories and route them to compliance.
- Work With the Right Suppliers
Designing out TSCA PBTs means choosing vendors who:
- Provide full material declarations (FMDs)
- Have internal compliance teams that understand TSCA 6(h)
- Offer pre-vetted, compliant product families
- Are responsive to declaration update requests
- Step 5: Document the Process
Good intentions aren’t enough—regulators want records. Create traceable documentation showing:
- Why a specific alternative was chosen
- Which PBTs were screened during design
- What supplier data was used to validate materials
- When compliance was confirmed, and by whom
Why This Matters
- Avoid costly redesigns and retrofits when a noncompliant part is flagged post-production
- Accelerate time-to-market with pre-cleared materials
- Protect your brand by reducing exposure to chemicals flagged for global regulation
How Acquis Helps
Acquis enables design-for-compliance by:
- Integrating BOM-level chemical screening into early-stage workflows
- Flagging restricted substances and suggesting known substitutes
- Maintaining a centralized audit trail of all design-time compliance decisions
Designing for compliance doesn’t slow you down it makes you faster, cleaner, and safer.
