How do I ensure my product meets US CPSC / Prop 65?
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 HarbourDirect AnswerUS 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 FailuresCPSC 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.

Children's Products: Testing and the CPCAnything 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.1Confirm the product is child-directedAge grading drives everything.2Identify applicable rulesLead, phthalates, small parts, ASTM F963.3Test at a CPSC-accepted labNot any lab - the acceptance list matters.4Issue the Children's Product CertificateImporter's responsibility.5Retain records and retest on changeAny material change resets it. Prop 65: Warn or Prove You Do Not Need ToProp 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 triggerWhere it shows upPractical responseLeadMetal parts, PVC, coatingsMaterial test reportPhthalatesSoft plastics, cords, gripsSpecify compliant plasticiserBPAHard plastics, can liningsRequest BPA-free confirmationCadmiumPigments, jewellery, solderTest the finished partApplying the warning label preemptively is a common commercial decision, not an admission.Warn when a listed chemical exceeds the safe harbour level. Get the Materials Right Before ProductionAlmost every CPSC and Prop 65 failure we have seen traces back to a material or component substitution nobody flagged.

Case: The Phthalate That Arrived With a Cost SavingBuyer: US brand, 8,000 children's activity setsThe 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.Most compliance failures start as an unflagged material change. How RND SOURCING Manages US ComplianceWe 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.Ask us to check your US compliance pathRND SOURCING — Yiwu, Zhejiang, China.
