How do I ensure my product meets US CPSC / Prop 65?

Question

Accepted Answer

Short Answer: Use Compliant Materials, Test Children's Products at a CPSC-Accepted Lab With a CPC, and Label for Prop 65 When a Listed Chemical Exceeds the Safe Harbour

Direct Answer

US consumer-product compliance has two hurdles that catch importers repeatedly. The CPSC requires that general consumer products are free of banned hazards, and that children's products are tested by a CPSC-accepted laboratory and covered by a Children's Product Certificate. That means working with suppliers who use compliant materials and retaining the test records yourself. California Proposition 65 is separate: if your product contains a listed chemical above the safe-harbour level, you must display the prescribed warning label, and many importers apply the label preemptively to avoid opportunistic litigation. Your agent should request the relevant test reports and confirm material compliance before production begins. Non-compliance risks recalls, fines and lawsuits, and fixing a problem after import costs many times what a pre-production check would have cost.

Two Separate Regimes, Two Different Failures

CPSC is federal product safety enforcement. Prop 65 is a California right-to-know law enforced largely through private lawsuits. They overlap in practice but they fail in different ways: a CPSC problem tends to arrive as a recall or a port hold, while a Prop 65 problem arrives as a demand letter from a plaintiff's firm.

CPSC

Banned hazards prohibited outright
Children's products need lab testing
Children's Product Certificate required
Recalls, fines, port holds

Prop 65

California-specific listed chemicals
Safe-harbour levels published
Warning label is the remedy
Private litigation is the enforcement

Children's products being tested in a safety laboratory — Child-directed goods must be tested at a CPSC-accepted lab.

Children's Products: Testing and the CPC

Anything primarily intended for children twelve and under is a children's product, and the bar is meaningfully higher. Third-party testing at a CPSC-accepted laboratory is mandatory, and you must issue a Children's Product Certificate that references those tests.

1

Confirm the product is child-directed

Age grading drives everything.

2

Identify applicable rules

Lead, phthalates, small parts, ASTM F963.

3

Test at a CPSC-accepted lab

Not any lab - the acceptance list matters.

4

Issue the Children's Product Certificate

Importer's responsibility.

5

Retain records and retest on change

Any material change resets it.

Prop 65: Warn or Prove You Do Not Need To

Prop 65 does not ban chemicals; it requires a clear warning when exposure exceeds the safe-harbour level. Because litigation is the enforcement mechanism and defence is expensive, many importers apply the label preemptively even when they believe they are under the threshold.

Common trigger	Where it shows up	Practical response
Lead	Metal parts, PVC, coatings	Material test report
Phthalates	Soft plastics, cords, grips	Specify compliant plasticiser
BPA	Hard plastics, can linings	Request BPA-free confirmation
Cadmium	Pigments, jewellery, solder	Test the finished part

Applying the warning label preemptively is a common commercial decision, not an admission.

A Proposition 65 warning label on consumer product packaging — Warn when a listed chemical exceeds the safe harbour level.

Get the Materials Right Before Production

Almost every CPSC and Prop 65 failure we have seen traces back to a material or component substitution nobody flagged. Compliance is a bill-of-materials problem long before it is a laboratory problem.

Lock the BOM in writingNamed materials and named suppliers.

Request material declarations upfrontBefore the first production run.

Test the finished item, not the raw sheetCoatings and inks matter.

Re-test after any substitutionA cheaper pigment resets your evidence.

Assume 'export quality' means compliantIt means nothing specific.

Case: The Phthalate That Arrived With a Cost Saving

Buyer: US brand, 8,000 children's activity sets

The factory quietly switched the soft grip material between the golden sample and mass production because the new supplier was cheaper. The replacement contained a restricted phthalate above the children's product limit.

OutcomeOur inspector caught the material change during in-line inspection, we pulled a sample for testing, and the run was reworked before shipment. A recall on a child-directed product would have cost the brand far more than the whole order was worth.

An inspector checking raw materials against a bill of materials — Most compliance failures start as an unflagged material change.

How RND SOURCING Manages US Compliance

We treat the bill of materials as a compliance document, not a costing sheet. Before production we get material declarations on paper, we confirm the lab is CPSC-accepted rather than merely accredited, and for child-directed goods we make sure the certificate is issued against the tests that actually apply. During production our inspectors watch for the quiet substitution that resets everything - it is the single most common cause of a US compliance failure and it never appears in an email. We would rather hold a run for three days than let a labelled carton become a recall.
