Lead content in children's products is governed by two separate federal rules that cover two different physical parts of the same product. 16 CFR 1303 caps lead in the surface coating (paint, lacquer, varnish, printing ink) at 90 parts per million by weight. 15 USC 1278a caps total lead in the substrate (wood, metal, plastic, textile) at 100 parts per million by weight for children's products. Compliance with both is required before a children's product can be certified and lawfully distributed in U.S. commerce. This guide walks the two rules end to end: what each covers, which CPSC test methods apply, how a CPSC-accepted third-party laboratory produces the underlying evidence, how the Children's Product Certificate references the test reports, and how the CPC data flows into the CPSC Product Registry eFiling regime mandatory as of 2026-07-08.
The single biggest source of confusion in practical CPSA compliance work is treating “lead in children's products” as one rule. It is two rules covering different physical parts of the same finished product.
16 CFR 1303 covers the surface coating. That is the paint, the printed decoration, the lacquer, the varnish, the enamel, or any similar coating applied to the outside surface of the product. The cap is 90 ppm (0.009 percent) lead by weight of the dried paint film or the total non-volatile content of the paint in the container. The rule applies to coatings on children's products and to coatings on furniture articles for consumer use. It also applies to paint itself sold to consumers.
15 USC 1278a covers the substrate. That is the physical material of the product under the coating — the plastic body of a toy, the metal frame of a stroller, the wooden dowel of a rattle, the textile fabric of a stuffed animal, the paper of a coloring book. The cap is 100 ppm total lead by weight in the accessible portion of the substrate for children's products. The rule was enacted in the Consumer Product Safety Improvement Act of 2008 (CPSIA) and stepped down over time to the current 100 ppm floor.
A painted wooden toy for a child under 12 has to test compliant against both rules. The wood substrate is tested against 15 USC 1278a at 100 ppm; the paint on the wood is tested against 16 CFR 1303 at 90 ppm. Both tests have to be run by a CPSC-accepted third-party laboratory. Both test reports have to be referenced (by lab name and report number) on the Children's Product Certificate. Both have to pass before the product can be certified and lawfully distributed. Missing either is a Section 14 compliance defect.
CPSC publishes standard test methods for lead-content determination that CPSC-accepted third-party laboratories run to generate the test report. Using a non-CPSC method or a modified method invalidates the report for CPC purposes even if the analytical result is scientifically sound.
CPSC-CH-E1003-09.1 — Lead in surface coatings. The test method for the 16 CFR 1303 90 ppm surface-coating cap. The lab removes a representative sample of the dried coating from the substrate (typically by scraping or by a solvent-assisted removal), digests the sample in acid, and quantifies lead content by ICP-OES or ICP-MS. The report cites the method reference, the sample ID, the sample-preparation procedure, the analytical result in ppm, and pass/fail against 90 ppm.
CPSC-CH-E1002-08.3 — Lead in non-metal children's product substrate. The test method for total lead in plastic, textile, wood, paper, and similar non-metal substrate materials. The lab prepares a representative sample of the substrate, digests it in acid, and quantifies lead content by ICP-OES or ICP-MS. Reports the same fields as the coating method, pass/fail against 100 ppm.
CPSC-CH-E1001-08.3 — Lead in metal children's product substrate. The test method for total lead in metal substrate materials. Similar procedure adapted for metal digestion. Pass/fail against 100 ppm.
The three methods together cover the substrate and surface-coating combinations that appear on essentially every painted or coated children's product. Products with multiple materials (a toy with a wooden body, a metal joint, and a painted decoration) generate three or more test reports — one per material per applicable rule — all referenced on the single Children's Product Certificate for the finished product.
The Section 14(a)(2) testing requirement is not satisfied by any competent laboratory — it is satisfied specifically by a CPSC-accepted third-party laboratory whose scope of accreditation covers the specific test method the report cites. CPSC maintains the accepted-laboratory list at the CPSC Laboratory Search page. The search is queryable by rule and by method; an importer confirming a lab's accepted status for lead-in-paint testing searches for CPSC-CH-E1003-09.1 and verifies the target lab appears in the results.
The accepted-lab status is per-method, not per-lab. A lab may be accepted for CPSC-CH-E1003-09.1 (lead in paint) but not for CPSC-CH-E1002-08.3 (lead in non-metal substrate), or vice versa. The importer confirms per-method acceptance for each test the CPC will reference; using an unaccepted lab or a method the lab is not accredited for invalidates the report for CPSA purposes.
The lab also has to be firewalled or independent from the manufacturer per 16 CFR Part 1112. Most children's product testing runs through third-party commercial labs (SGS, Intertek, Bureau Veritas, TUV Rheinland, UL, ACT Labs, QIMA, and many others) that satisfy the firewalled-independent requirement by structural separation. A manufacturer running an in-house lab has to affirmatively meet the 16 CFR Part 1112 firewalled-lab criteria and be independently accepted by CPSC for that status; this is a smaller subset of practical cases.
The test sample the lab actually digests has to be representative of the population of finished products the CPC will cover. Sampling protocol is defined in 16 CFR Part 1107 (the periodic-testing and material-change regulation). The default rule is that the tested sample is drawn from the same production run and same materials-and-processes lot as the finished products the CPC covers. A test report generated from a sample of aluminum from a different mill run, or a paint sample from a different batch, does not support the CPC for the actual products.
Sampling for periodic testing (after the initial certification) is at least annually per model per rule, and any material change in the product (composition, supplier, production location, manufacturing process) triggers a material-change test on top of the annual periodic-testing baseline. A shift in paint supplier that changes the lead-content profile is a material change. A shift in the plastic substrate supplier is a material change. A shift in manufacturing location typically is not a material change if the same materials are used, but the analysis is fact-specific and turns on whether the material change affects the compliance profile.
The Children's Product Certificate is the document under Section 14(a)(1) (15 USC 2063(a)(1)) that the U.S. importer or U.S. manufacturer signs identifying the finished product, the applicable rules the product complies with, the CPSC-accepted lab that ran each test, the test-report reference number, and the tested model. The CPC has to be in English, has to be legible, and has to accompany the product or be furnished to distributors and retailers on request. For the lead rules specifically, the CPC lists:
• The 15 USC 1278a total-lead-content compliance affirmation with the CPSC-accepted lab that ran the CPSC-CH-E1002-08.3 or CPSC-CH-E1001-08.3 test, the report reference, and the tested model.
• The 16 CFR 1303 lead-in-paint compliance affirmation with the CPSC-accepted lab that ran the CPSC-CH-E1003-09.1 test, the report reference, and the tested model.
Both compliance affirmations sit on the same CPC alongside the other applicable rules for the specific product (phthalate content, small-parts, mechanical hazards, flammability, category-specific rules like cribs at 16 CFR 1219/1220 or high chairs at 16 CFR 1231). The CPC references the tests but does not carry the test-report PDFs. The reports themselves live in the importer's or manufacturer's files and are produced to CPSC on request under Section 14(g).
The CPSC Product Registry eFiling mandate went effective 2026-07-08 and requires the CPC data (not the test-report PDFs) to transmit electronically into CPSC's Product Registry at entry for every children's product entering U.S. commerce. The transmitted data set includes the tested-and-certified product model, the applicable rules, the CPSC-accepted labs, and the compliance affirmation. The underlying test reports remain in the responsible party's records; the eFiling regime creates a digital record of the certification chain that CPSC can query and cross-reference against enforcement actions.
For the lead rules specifically, the eFiling data set includes the two lead-compliance affirmations described above — one for 15 USC 1278a and one for 16 CFR 1303 — each pointing at the applicable lab and report. Missing either affirmation on a children's-product eFiling packet causes the entry to be flagged for review and can delay clearance. EntryProof's readiness-assessment tool at /cpsc-efile/checker confirms that both lead affirmations are present in the packet and that the referenced lab and method align with the CPSC-accepted status before the packet transmits.
1. Substrate-only test on a painted product. A CPC that references only the 15 USC 1278a substrate test on a painted children's product is missing the 16 CFR 1303 lead-in-paint compliance affirmation. Even if the substrate test passes at 100 ppm, the CPC is incomplete without the paint test. Fix: run the lead-in-paint test on the surface coating using CPSC-CH-E1003-09.1 at a CPSC-accepted lab and update the CPC.
2. Paint-only test on a plastic-substrate product. The reverse mistake: a CPC references only the 16 CFR 1303 paint test and omits the substrate test. Even if the paint test passes at 90 ppm, the plastic substrate has to test at or below 100 ppm total lead under 15 USC 1278a. Fix: run the substrate test using CPSC-CH-E1002-08.3 at a CPSC-accepted lab and update the CPC.
3. Test method mismatch. A lab report cites an ASTM method or an ISO method or a general ICP-OES procedure rather than the CPSC-published method. The report is scientifically sound but does not satisfy the Section 14 requirement, which is method-specific. Fix: re-run the test using the correct CPSC-published method at a CPSC-accepted lab whose scope of accreditation covers that method.
4. Lab not CPSC-accepted for the specific method. A general ISO/IEC 17025 lab runs the correct CPSC-published method, but the lab is not on the CPSC-accepted list for that specific method. Fix: confirm the lab's CPSC-accepted status per method on the CPSC Laboratory Search page before commissioning testing; if the lab is not accepted for the specific method, use a different lab or a different accredited scope at the same lab.
5. Stale test on a materially-changed product. The CPC references a test that is more than a year old (violating the annual periodic-testing floor), or a test run before a material change in composition, supplier, or process. Fix: re-test per 16 CFR Part 1107 periodic-testing or material-change protocol and update the CPC.
Distributing a children's product that fails a lead test, or that lacks a valid CPC citing a passing test, is a violation of Section 19 of the Consumer Product Safety Act (15 USC 2068). Civil penalties for CPSA violations are set under Section 20 (15 USC 2069) at up to $120,000 per violation and up to $17,150,000 for a related series of violations (both figures adjusted for inflation and updated periodically by CPSC). CPSC has enforced lead-in-paint and lead-in-substrate violations against major importers of children's products with civil penalties in the multi-million-dollar range in the years since CPSIA's enactment; enforcement activity is publicly documented on CPSC's Recall & Civil Penalty page.
The exposure attaches to both the U.S. importer and the U.S. manufacturer as the responsible party under Section 14(a)(1). Retailers and distributors of the product may also be exposed to Section 19 enforcement if they knew or should have known of the violation. The eFiling regime creates a persistent digital record of the certification chain that CPSC can query on enforcement, which materially increases the practical cost of a missing or invalid CPC line for a lead compliance affirmation.
EntryProof does not run lead tests and is not a testing laboratory. Its role in a lead-compliance workflow is preparation and packet-readiness: confirming that the CPC on file references the correct rules (both 15 USC 1278a and 16 CFR 1303 as applicable), that the referenced test methods are the CPSC-published methods, that the referenced labs are CPSC-accepted for those specific methods, and that both compliance affirmations are present in the packet transmitting into the CPSC Product Registry at entry. The EntryProof readiness checker runs this check across a full CPC portfolio and flags missing or misaligned affirmations before the packet transmits.

16 CFR 1303 is the Consumer Product Safety Commission’s ban on lead-containing paint and similar surface coatings. It caps lead content in paint and other surface coatings at 0.009 percent (90 parts per million) by weight of the total non-volatile content of the paint, or the weight of the dried paint film. The rule applies to any surface coating on a children’s product and to any surface coating on furniture articles for consumer use. It does not apply to substrate (the material under the coating) -- substrate lead in children’s products is governed by the separate total-lead-content limit in 15 USC 1278a, capped at 100 ppm.
They cover different physical parts of the product and use different test methods. 16 CFR 1303 covers surface coatings -- paint, lacquer, varnish, printing ink, and similar materials -- and caps lead at 90 ppm by weight of the dried film. 15 USC 1278a covers the substrate itself -- the wood, metal, plastic, textile, or other material the coating sits on -- and caps total lead content at 100 ppm by weight in the accessible portion of the substrate. A children’s product typically has both: a substrate that has to test at or below 100 ppm total lead, and (if painted) a surface coating that has to test at or below 90 ppm lead. Both are required for a compliant Children’s Product Certificate; either failing is a Section 14 compliance defect.
The CPSC-published test method for lead in a paint or surface coating is CPSC-CH-E1003-09.1. The method involves scraping or removing a representative sample of the dried coating from the product substrate, digesting the sample in acid, and quantifying lead content by inductively coupled plasma optical emission spectroscopy (ICP-OES) or ICP mass spectrometry (ICP-MS). The test is run by a CPSC-accepted third-party laboratory whose scope of accreditation covers CPSC-CH-E1003-09.1 specifically. The lab report cites the method, the sample identification, the analytical result in ppm, and pass/fail against the 90 ppm limit. That report is the primary evidence the Children’s Product Certificate references for the lead-in-paint compliance line.
For a non-metal substrate (plastic, textile, wood, paper, and similar), the CPSC-published test method is CPSC-CH-E1002-08.3. For a metal substrate, the method is CPSC-CH-E1001-08.3. Both involve preparing a representative sample of the substrate, digesting it in acid, and quantifying total lead content by ICP-OES or ICP-MS. As with the paint test, the substrate test is run by a CPSC-accepted third-party laboratory whose scope of accreditation specifically covers the applicable method. The lab report cites method, sample ID, result in ppm, and pass/fail against the 100 ppm limit for children’s products under 15 USC 1278a.
16 CFR 1303 covers paint or surface coatings on children’s products (products designed or intended primarily for children 12 or under) and on furniture articles for consumer use. It also applies to the paint itself in the container -- a paint product sold to consumers is subject to the 90 ppm cap regardless of end use. Products explicitly outside the scope of the rule include agricultural and industrial equipment paint, industrial building paint, artist paint, and lead-content paint used in ways that will not result in child exposure (e.g., certain marine, industrial coatings applied in commercial settings). The scope exclusions are narrow; anyone assuming an exclusion applies should confirm against the regulatory text.
A failed test means the product cannot be certified against the applicable lead rule and cannot be lawfully distributed in U.S. commerce as a children’s product (or lawfully sold as furniture, for the surface-coating rule). Options are to reformulate the paint or substrate to bring lead content below the applicable limit and re-test, to source a different substrate or coating, or to redirect the product to a market outside the U.S. Distributing a children’s product with a failed lead test is a violation of Section 19 of the Consumer Product Safety Act (15 USC 2068) and exposes the responsible party to civil and potentially criminal penalties under Section 20 (15 USC 2069) and Section 21 (15 USC 2070).
The Children’s Product Certificate cites the applicable lead rules the product complies with, identifies the CPSC-accepted third-party laboratory that ran each test, identifies the test-report reference number, and identifies the tested product model. The CPC is signed by the U.S. importer or U.S. manufacturer. Post-2026-07-08, the CPC data transmits electronically into the CPSC Product Registry at entry, and the entry cannot proceed without valid CPC data on file. The underlying test-report PDFs themselves do not transmit -- they are retained by the responsible party and produced to CPSC on request.
