California Proposition 65 Compliance
Ensuring precision elastomers, molded rubber gaskets, and polyurethane components comply with the California Safe Drinking Water and Toxic Enforcement Act of 1986.
Understanding California Proposition 65 Requirements
OEHHA RegulatedCalifornia Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, requires businesses operating in or selling goods into the State of California to provide warnings if their products contain any chemicals known to cause cancer, birth defects, or other reproductive harm above established safe harbor levels.
The regulated chemicals list administered by OEHHA contains over 900 individual substances. For rubber, plastic, and polyurethane manufacturers, the primary focus areas include regulated ortho-phthalate plasticizers (such as DEHP, DBP, BBP, DINP, DIDP, and DNHP), heavy metal stabilizers (lead, cadmium), and certain polycyclic aromatic hydrocarbons (PAHs).
Key Highlights & Declarations:
- Covers over 900 chemicals updated annually by California OEHHA.
- Enforces strict No Significant Risk Levels (NSRLs) and Maximum Allowable Dose Levels (MADLs).
- Mandatory warning labels required if exposure exceeds safe harbor thresholds.
- Direct civil litigation risk for non-compliant consumer and industrial equipment suppliers.
Horiaki India's Chemical Sourcing & Formulation Safeguards
Phthalate-Free CompoundsHoriaki India Private Limited manufactures technical polymer components destined for the North American market using clean, modern compounding chemistry. Our compounding formulations for FFKM, FKM, Silicone, EPDM, NBR, and Polyurethane explicitly avoid restricted ortho-phthalate plasticizers.
We utilize high-molecular-weight polymeric and bio-based ester plasticizers that are inherently non-toxic and compliant with Prop 65 safe harbor limits. For food-contact, medical, and drinking water seals, our materials are formulated exclusively with FDA-sanctioned and heavy-metal-free curatives, eliminating the requirement for Proposition 65 warning labels.
Key Highlights & Declarations:
- Zero addition of banned ortho-phthalates (DEHP, DBP, BBP, DINP, DIDP, DNHP).
- Lead-free and cadmium-free vulcanization activators and metal inserts.
- Gas Chromatography-Mass Spectrometry (GC-MS) screening for volatile and extractable compounds.
- Formal Proposition 65 Certificate of Conformity provided for US procurement teams.
Certification Support for US OEM Importers & Distributors
When exporting to US ports (Los Angeles, Long Beach, New York, Houston), Horiaki issues signed Product Compliance Certificates confirming that the supplied components do not expose end-users to regulated substances above OEHHA limits, shielding North American OEMs and distributors from Proposition 65 legal exposure.
Key Highlights & Declarations:
- Batch-specific chemical conformity certificates upon request.
- Full compatibility with US tier-1 automotive, appliance, and water infrastructure specifications.
- Direct technical review via raj@horiaki.com.
