What is the difference between total lead content and soluble lead content?

Total lead content (measured by CPSC-CH-C1001) measures all lead present in the material, whether chemically bound or free. Soluble lead (measured per ASTM F963 / EN 71-3) measures only the lead that can be extracted under simulated gastric fluid conditions — the portion a child could absorb if they ingested or chewed the material. Both limits must be met independently: 100 ppm total lead under CPSIA and 90 mg/kg soluble lead under ASTM F963 Section 4.3.5.

Can I use XRF results to issue a Children’s Product Certificate?

No. The CPSC requires that CPCs be based on testing by a CPSC-accepted laboratory using accepted test methods. XRF is not a CPSC-accepted test method for issuing a CPC — it is only a screening tool. Test results used to support a CPC must come from ICP-MS or ICP-OES analyses conducted in accordance with CPSC-CH-C1001/C1002 or the applicable ASTM F963 procedure.

If my toy has multiple components from different suppliers, do each component need to be tested?

Yes, if those components are accessible to children. Under CPSIA, the lead limits apply separately to each accessible substrate component and surface coating. A passing result on one component does not certify other components. Your test plan should include all accessible components that could contain lead — particularly painted metal parts, colored plastic components, fabric treatments, and surface coatings.

Is lead testing required for every production batch?

The CPSC does not require batch-by-batch testing for every shipment, but the CPC must accurately reflect the current production version. If you change your supplier, manufacturing process, or any material, you must retest and issue a new CPC. Many brands implement periodic re-testing (e.g., annually or with each new production run) as a best practice to maintain defensible compliance records.

What is 16 CFR 1303, and how does it relate to CPSIA?

16 CFR Part 1303 is the CPSC’s regulation banning lead-containing paint on consumer products and toys, predating CPSIA. It established the original 600 ppm lead-in-paint limit, later superseded by the 90 ppm limit in CPSIA. Today, 16 CFR Part 1303 works in conjunction with CPSIA Section 101: 16 CFR 1303.4 sets the 90 ppm surface-coating limit, while CPSIA Section 101 establishes the 100 ppm total-substrate limit.

My product is manufactured overseas. Do overseas labs qualify for CPC testing?

Yes, foreign laboratories can be used for CPC testing as long as they are CPSC-accepted for the specific test methods required. The CPSC maintains a list of accepted laboratories at cpsc.gov. Many major testing laboratories in China, India, Europe, and Southeast Asia are CPSC-accepted. Always verify the lab’s acceptance scope covers the exact methods your product requires before submitting samples.
