Substance Regulations

California Proposition 65 Compliance Screening

Check every part on your BOM against the Prop 65 list and see which components put a California warning obligation on your product, with source documentation behind each result.

Listed chemicals that put a warning duty on your product

California Proposition 65 covers roughly 900 chemicals known to cause cancer or reproductive harm, and the state adds more each year. Compliance Manager screens your whole BOM against the current list, so here is what you get.

BOM screening

Screen Your BOM Against the Prop 65 List

Upload your BOM and material declarations, and see every component checked against the current Proposition 65 list.

  • Meaningful coverage on day one from Z2's FMD and CoC database.
  • Monitoring and alerts keep the assessment current as the state adds substances.
  • A newly listed chemical in a part you already ship never slips past you.

Warning duty

Pinpoint the Parts That Trigger a Warning

Knowing a substance is present is not enough: you need to know which part carries it and whether it puts a warning duty on the product.

  • Each component classified Affected, Not Affected, or Noncompliant.
  • Item rollup carries the result from components up to the finished product.
  • Every listed substance traced back to the responsible part, supplier, and declaration.

Verified data

Carry the Evidence Behind Every Flag

Prop 65 enforcement runs on private litigation, so the burden is on you to substantiate every warning decision.

  • Certificates of compliance and full material declarations behind each result.
  • Supplier documentation attached per your risk tolerance.
  • The source behind any result downloadable, not reconstructed later.

One platform

Part of Z2 Compliance Manager

Prop 65 is one of more than 270 global regulations Compliance Manager screens on the same BOM.

  • REACH, RoHS, TSCA, and China RoHS in one platform.
  • Item rollup shows warning obligations at every level of the product hierarchy.
  • Z2's compliance team runs supplier outreach to collect any missing declarations.

Common Questions

How does Z2 determine whether a part triggers a Prop 65 warning?

Compliance Manager assesses each component's material declaration against the Proposition 65 list and classifies it as Affected, Not Affected, or Noncompliant. When a listed substance is present, it flags the part, ties the result to the supporting declaration, and rolls it up to show product-level warning obligations.

The Prop 65 list changes every year. How does Z2 keep my assessment current?

Z2 keeps the assessment current as the state adds substances, and alerts notify you when a newly listed chemical affects a part you already ship. Z2's in-house materials scientist also helps customers stay ahead of regulatory updates.

How does Z2 help me substantiate a warning decision?

Prop 65 enforcement runs on private litigation, so the burden is on you to substantiate every warning decision. Each assessment carries an evidence package of certificates and full material declarations, plus supplier documentation per your risk tolerance, so you can download the source behind any result rather than reconstruct it later.

Is Prop 65 screening separate from my other compliance work in Z2?

No. Prop 65 screening is part of Z2 Compliance Manager, which assesses your BOM against more than 270 global environmental regulations in one workspace. A single BOM surfaces your California warning obligations alongside REACH, RoHS, TSCA, and others, all from the same product hierarchy.
