China will enforce a mandatory national safety standard for cosmetics from 1 January 2028, replacing hygiene rules that have stood since 1987 and imposing some of the strictest microbiological limits in the market's history. The National Medical Products Administration (NMPA) formulated the standard, and the State Administration for Market Regulation issued it.

For formulators and quality teams exporting to or producing in China, the document is a full-spectrum benchmark: it caps microbes, heavy metals and other harmful substances for every cosmetic produced and sold in the country.

What does the standard restrict?

The rules set quantitative limits on bacteria, mould and yeast in finished products. They go further and prohibit outright several microorganisms that pose serious health risks:

• Thermotolerant coliforms
• Staphylococcus aureus
• Pseudomonas aeruginosa

The standard draws in part on microbiological limits set by the International Organization for Standardization (ISO), but it tightens requirements for certain product categories. That means multinationals running global formulations cannot simply assume ISO-aligned specs will pass Chinese testing.

How much stricter are children's products?

For cosmetics intended for children, the requirements are roughly 10 times stricter than the baseline. The provisions apply mainly to:

• Cleansers
• Moisturizers
• Powders
• Sunscreens

The scope covers products for children up to 12 years of age, plus items used around the eyes, on eyelashes and on the mouth and lips. Brands in the kids' personal care segment face the largest reformulation and testing burden — preservative systems validated under 1987-era assumptions may not hold at the tighter microbial thresholds.

Which heavy metals are capped?

The standard sets maximum limits for eight harmful substances, including lead, arsenic, mercury and cadmium. Procurement teams should note the raw material clause: where ingredients can leave residues of methanol, asbestos, benzene or other hazardous substances, manufacturers must strictly control those residue levels and increase testing.

That shifts workload upstream. Suppliers of talc, ethanol-derived inputs and solvent-extracted botanicals can expect tighter incoming-inspection regimes and more certificates of analysis requested by Chinese manufacturers preparing for 2028.

Why is China acting now?

The rules come as safety oversight strains to keep pace with an industry that has expanded dramatically. NMPA data shows China's cosmetics market surpassed 1.1 trillion yuan ($163 billion) for the first time in 2025, up 2.8 percent year-on-year. The number of cosmetics manufacturers has grown from about 70 in 1980 to more than 6,000 in 2026.

A regulatory framework written when the industry counted dozens of producers now governs thousands. Authorities described the new standard to China Daily as a comprehensive safety benchmark for all cosmetics produced and sold in China.

What should compliance teams do before 2028?

The effective date leaves roughly two years — a realistic but not generous window for global portfolios. Practical priorities include:

• Gap assessments of current microbial and heavy metal test results against the new limits, especially for eye-area, lip and under-12 products where the 10x stringency applies
• Supplier audits on residue-bearing raw materials flagged in the standard
• Updated stability and challenge testing for preservative systems in children's lines

Manufacturers selling into China will also need to align internal release specifications before the deadline, since the standard applies at the point of production as well as sale.

The next data points to watch: the NMPA's implementing guidance and testing method appendices expected ahead of the 1 January 2028 enforcement date, which will determine exactly how the ISO-based limits translate into laboratory protocols.
