ABS Recycled Plastic Passes All Five US EPA TSCA PBT Chemical Limits — CTI Lab Verification Report

Good News for Recycled Plastics — Black ABS Just Cleared All Five EPA PBT Hurdles

    If you're sourcing or supplying recycled ABS plastic in the U.S., this is one of those “breathe-easier” moments. A recent independent verification report from CTI Lab confirms that a batch of black recycled ABS plastic granules meets *all five* U.S. EPA PBT chemical limits under TSCA Section 6(h). That means it’s officially compliant with the strictest federal thresholds for DecaBDE, PIP(3:1), 2,4,6-TTBP, HCBD, and PCTP — no exceptions, no waivers.

Why These Five Chemicals Matter So Much

    These aren’t just acronyms on a compliance checklist — they’re persistent, bioaccumulative, and toxic (PBT) substances flagged by the EPA because they stick around in the environment, build up in living organisms, and pose real health risks. Under TSCA Section 6(h), manufacturers and importers must ensure their products contain these chemicals *below legally defined cutoffs*. For recycled ABS — which often comes from post-consumer electronics or automotive parts — trace contamination is a real concern. That’s why passing all five at once is a big deal.

How Was It Tested? Rigor You Can Trust

    CTI Lab used validated GC-MS (gas chromatography–mass spectrometry) methods — the gold standard for detecting ultra-low levels of organic contaminants. Each chemical was quantified down to parts-per-trillion sensitivity where required. The results? All five came in well below the EPA’s enforceable limits: DecaBDE < 10 ppm, PIP(3:1) < 100 ppm, 2,4,6-TTBP < 10 ppm, HCBD < 10 ppm, and PCTP < 100 ppm. Not just “below detection” — fully quantified and verified.

What This Means for Your Business

    For brands aiming for ESG-aligned supply chains, this verification isn’t just about ticking a box — it’s proof your recycled ABS is truly sustainable *and* safe. It supports responsible sourcing claims, helps avoid customs delays or EPA enforcement actions, and strengthens customer trust — especially in regulated sectors like electronics, medical devices, and children’s products. Plus, having a formal compliance certification backed by third-party GC-MS data makes due diligence faster and more defensible.

Bottom Line

    Recycled ABS doesn’t have to mean compromise. This verification shows that high-quality recycling, rigorous testing, and regulatory awareness can go hand-in-hand. Whether you’re a material supplier, converter, or brand owner, knowing your black ABS clears all five EPA PBT hurdles gives you real leverage — in the lab, on the shelf, and in the boardroom.
