The safety of children's products has never been under greater scrutiny in China. With the official implementation of GB 6675.4-2025 on November 1, 2026, replacing the 2014 version, China has significantly tightened the limits for lead (Pb) and cadmium (Cd) migration from toy materials – particularly from paints, coatings, plastics, and textiles. For foreign manufacturers and importers of toys, these updates are not merely technical adjustments; they carry severe consequences, including shipment holds, product recalls, and potential market withdrawal. This guide provides a complete breakdown of the new lead and cadmium limits, the scope of affected toy materials, testing requirements, transition periods, and a practical compliance roadmap to ensure your products meet China’s highest-ever safety standards.
1. Why the Stricter Lead and Cadmium Limits Matter
Lead is a neurotoxin that can cause irreversible developmental damage, reduced IQ, and behavioral issues in children, with effects occurring even at very low exposure levels. Cadmium is a known carcinogen that accumulates in the kidneys and bones, with chronic exposure linked to renal dysfunction and skeletal damage. Young children are particularly vulnerable due to their hand-to-mouth behavior and higher absorption rates. According to a 2025 consumer product recall report, lead and cadmium exceeding permissible levels were among the top chemical reasons for toy recalls in China, alongside excessive phthalates[reference:0]. In response, China has revised its toy safety framework to align more closely with international standards (ISO, EU) while introducing specific domestic protections, culminating in the stricter migration limits now codified in GB 6675.4-2025[reference:1]. The updated regulation is part of a broader effort by the State Administration for Market Regulation (SAMR) to close regulatory gaps for new toy types, particularly soft plastics and modeling materials, and to reflect the latest scientific understanding of children's exposure to chemicals[reference:2].
2. New Lead (Pb) and Cadmium (Cd) Migration Limits Under GB 6675.4-2025
GB 6675.4-2025, titled “Safety of toys – Part 4: Migration of certain elements,” establishes the maximum allowable amounts of specific heavy metals that can migrate from toy materials into a child’s body (simulated by a stomach acid extraction process). While the 2025 edition did not change the numerical limits for lead and cadmium from the 2014 edition, it significantly expanded the range of materials and scenarios to which these strict limits apply, effectively broadening enforcement.
The key point for importers to understand is the distinction between migration limits (the amount of a substance that can be released from the material) and total content limits (the total amount present in the material). For toys, China uses migration limits, which are more directly related to potential harm. The lead and cadmium migration limits under GB 6675.4-2025 apply to a wide array of toy materials, as detailed in the table below[reference:3]. Note: For imported toys containing small metal components (e.g., jewelry or keychains), separate regulations such as GB 28480-2012 may also apply, as detailed in the next section.
2.1 Scope of Affected Materials
- Paints, coatings, varnishes, inks, polymer coatings: All surface coatings on toys, regardless of the base material.
- Polymers and similar materials: Including plastics, rubber, and silicone components.
- Paper and cardboard: Used in books, puzzles, and packaging intended to be kept.
- Textiles (natural, artificial, or synthetic): Such as toy clothing, doll hair, and stuffed animal fur.
- Glass, ceramic, and metal materials: Including metal gears, glass eyes, and ceramic decorative elements (excluding lead solder used for electrical connections).
- Other materials: Wood, fiberboard, leather, and any pliable modeling materials.
2.2 Strictest Enforcement for High-Risk Scenarios
GB 6675.4-2025 applies its strictest limits in scenarios where ingestion is most likely, including:
- Toys intended for children under 36 months (any accessible material).
- Toys that can be placed in the mouth by older children (e.g., mouth-actuated toys).
- All accessible coatings, regardless of child's age.
- Accessible liquids, pastes, and gels (e.g., toy paint, slime).
- Materials that would be considered “suckable, lickable, or swallowable” based on a child’s foreseeable behavior.
2.3 Comparison: GB 6675.4 vs. GB 28480 for Children's Jewelry
Importers of children’s jewelry need to be aware of a separate standard: GB 28480-2012 “Hazardous substances limits for jewelry.” For products categorized as “children’s jewelry,” the total lead content limit is set at 300 mg/kg (0.03%), and the total cadmium limit at 100 mg/kg (0.01%)[reference:4]. While the limits under GB 28480 may seem numerically higher or lower depending on the element, compliance with one standard does not automatically confer compliance with the other. Importers must confirm which classification applies to their product and ensure compliance with the relevant standard.
3. Enforcement and Penalties for Non-Compliance
Non-compliance with GB 6675.4-2025 can have severe repercussions for importers. The penalty framework includes:
- Customs detention: Shipments with non-compliant toys can be held at the port of entry, leading to storage fees and demurrage.
- Shipment destruction or return: If the violation is severe, customs may order the destruction of the entire shipment at the importer's expense, or force its return to the country of origin.
- Substantial fines: Product value-based fines can be levied, often amounting to many times the cost of the goods.
- Product recall: Already distributed products may need to be recalled from the market, a logistically complex and brand-damaging process.
- Loss of market access: Repeat or severe violations can lead to blacklisting, where all future shipments from that manufacturer are subject to 100% inspection or an outright import ban.
4. Testing Requirements: Migration vs. Total Content and Proper Labs
To prove compliance with the new limits, importers must provide laboratory test reports. A critical distinction to understand is between migration testing (the amount of a substance that can leach from a material) and total content testing (the total amount present). GB 6675.4-2025 requires migration testing, which is a more relevant measure of potential harm. This is simulated using an acidic extraction process to represent a child’s stomach. Reports must be from labs with CNAS (China National Accreditation Service for Conformity Assessment) accreditation. While a Certificate of Analysis (COA) from the manufacturer is a helpful internal document, it is not a substitute for a formal test report from an accredited third-party lab. For final products, an ICP-MS or ICP-OES test report from a CNAS lab is mandatory[reference:6].
5. Transition Periods: Key Deadlines for Importers
Understanding the transition schedule is critical to avoid shipping non-compliant goods.[reference:7]
- Production & Import Transition: The new standard officially enters into force on November 1, 2026. Toys manufactured or imported before this date can still be placed on the market, but the deadline for selling such "old standard" inventory is November 1, 2027 (12 months after the implementation date).
- Action Plan: Importers should aim to have all their products fully compliant with GB 6675.4-2025 well before November 1, 2026. Relying on the 12-month sell-through period for non-compliant inventory is a risky business strategy, as customs may not differentiate at the port. The stock on the market after November 1, 2026, can include products manufactured to the old standard, but they must clear customs before that date.
- CCC Certification Transition: Starting August 1, 2026, all new CCC applications for toys must be based on the 2025 standards. To avoid disruptions, importers with CCC certificates expiring around this period should plan for early renewal under the new system.
6. Practical Compliance Roadmap for Importers
To ensure a seamless transition, follow this five-phase compliance roadmap:
- Supplier Material Audit (Phase 1, Immediate): Contact your overseas manufacturers and request detailed material composition reports, including specifications on paints, coatings, plastics, and metals. Ask for third-party test reports for lead and cadmium migration to confirm compliance with GB 6675.4-2025 limits.
- Pre-emptive Laboratory Testing (Phase 2, 3-4 months pre-deadline): Engage a CNAS-accredited testing lab in China to conduct full migration tests on your toy products. Do not wait for a shipment to arrive at customs; pre-emptive testing allows you to identify and correct compliance issues at the source.
- Review and Update Supply Chain Contracts (Phase 3): Amend your supply agreements to explicitly require compliance with GB 6675.4-2025 and include indemnity clauses for non-compliance. Request that your supplier adhere to a rigorous testing regime for each batch of raw materials and finished products.
- Manage Inventory and Logistics (Phase 4, 4-6 months pre-deadline): Plan your production and shipping schedule to ensure all final products manufactured from January 2027 onwards (and ideally much earlier) are 100% compliant with the new standard. For high-risk categories like paints and coatings, aim for compliance as soon as possible.
- Internal Compliance Management (Phase 5, Ongoing): Appoint a dedicated compliance officer or partner with a China-based regulatory agent to monitor updates to GB standards and manage the CCC certification process, which must align with GB 6675.4-2025 from August 1, 2026, onward.
7. Case Study: Lead in Paint – A Costly Lesson in Non-Compliance
In 2025, a major toy manufacturer shipped over 18 million Chinese-made dolls, cars, and action figures that were recalled globally due to lead contamination in surface paints[reference:8]. The CPSC recall bulletin noted that the products "contain high levels of lead in their surface paint," and that children’s products found to have more than 0.06% (600 mg/kg) of lead accessible to users are subject to a recall[reference:9]. While the recall was led by U.S. authorities, it had a direct impact on the Chinese supply chain, as the factory was forced to halt production for extensive remediation, orders were cancelled, and the importer faced significant financial and reputational damage. This case underscores a critical point: non-compliance can lead to crises that transcend individual markets. With China’s random inspection system now in effect, a shipment could be pulled for inspection at any time, and a failure would be flagged in the national compliance database, potentially affecting all future shipments.
Summary: GB 6675.4-2025 has expanded the strict lead and cadmium migration limits to a wider range of toy materials and child-specific scenarios. Importers must transition away from managing compliance at the port of entry and begin implementing a proactive, upstream quality management process. By understanding the new rules, retooling supplier contracts, conducting pre-emptive testing at CNAS labs, and engaging a local agent, you can ensure your products meet China’s highest-ever safety standards and avoid costly recalls or shipment holds.
