Cosmetics registration and notification testing is the mandatory laboratory testing regime that every cosmetic product must complete before it can be legally placed on the Chinese market under the supervision of the National Medical Products Administration (NMPA). This technical guide explains the regulatory framework, sample requirements, testing categories, analytical methods, and compliance pathways that brands, manufacturers, and importers need to understand. Whether you are filing a general cosmetic or registering a special-use product, accurate testing is the foundation of a successful market entry strategy in China.
Technical Overview
Cosmetics registration and notification testing refers to the compulsory safety and quality testing required under China's regulatory system for cosmetics. The legal framework is established by the Cosmetics Supervision and Administration Regulation (CSAR), which came into force on January 1, 2021, and is administered by the National Medical Products Administration (NMPA). Under this system, all cosmetics are divided into two categories: general cosmetics, which follow a notification (filing) procedure, and special cosmetics, which require a formal registration (approval) procedure.
Special cosmetics include hair dyeing products, hair perming products, skin-whitening and spot-fading products, sunscreens, anti-hair-loss products, and products claiming new efficacy functions. The technical basis for all testing is the Safety and Technical Standards for Cosmetics (2015 Edition), which specifies mandatory test methods, limit values for restricted substances, and microbial control requirements.
All mandatory safety testing must be performed by NMPA-recognized cosmetics registration and notification testing institutions. These are accredited third-party laboratories that have passed qualification review and are listed on the national information service platform. Test reports are uploaded electronically and linked to the product dossier during the notification or registration process. In addition, since 2021, every efficacy claim made on a product label must be supported by scientific evidence, including laboratory tests, human efficacy trials, consumer use tests, or documented research data, in accordance with the national standards for cosmetic efficacy claim evaluation.
Testing Samples
General Cosmetics
General cosmetics cover the majority of the market, including skin care products such as creams, lotions, essences, and masks; color cosmetics such as foundation, lipstick, and eye makeup; hair care products such as shampoo and conditioner; nail products; and fragrance products. Samples submitted for testing must be from the final production formula, produced under conditions representative of commercial manufacturing, and packaged in the intended market container.
Special Cosmetics
Sunscreens, hair dyes, hair perming products, whitening products, and anti-hair-loss products are subject to an expanded testing scope. These products typically require additional toxicological studies, human safety trials, and efficacy verification such as in vivo sun protection factor (SPF) determination for sunscreen products.
New Cosmetic Ingredients
Companies introducing new ingredients to the Chinese market must submit toxicological and safety data for the ingredient itself, which may include acute toxicity, genotoxicity, repeated-dose toxicity, skin sensitization, and phototoxicity assessments depending on the ingredient's use history and exposure profile.
Sample Quantity and Preparation
The required sample quantity depends on the number and type of test items selected. As general guidance, laboratories typically request several full retail units or 100–500 grams per product, taken from the same production batch. Samples must be accompanied by the full ingredient list with percentage composition, product usage instructions, target user group (adults or children), and application area, since these factors determine the applicable microbial limits and toxicological test battery.
Testing Items
The testing program for cosmetics registration and notification is structured around four core pillars, supplemented by efficacy claim evaluation:
- Microbiological testing: total aerobic plate count, total mold and yeast count, and detection of specified pathogenic organisms including Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans.
- Hygienic and physicochemical testing: pH determination and quantitative analysis of heavy metals and restricted substances.
- Toxicological safety testing: acute and repeated skin irritation, eye irritation, skin sensitization, acute oral toxicity, and phototoxicity where chemically or functionally indicated.
- Human safety and efficacy testing: human repeated insult patch testing (HRIPT) for certain product categories, in vivo SPF and UVA protection factor measurement, water resistance testing, and claim substantiation trials.
Key limit values under the Safety and Technical Standards for Cosmetics (2015 Edition) include:
- Total aerobic microbial count: not more than 1,000 CFU/g or CFU/mL; not more than 500 CFU/g or CFU/mL for products used on eye area, lips, mucous membranes, or children's skin.
- Total mold and yeast count: not more than 100 CFU/g or CFU/mL.
- Pathogenic organisms: must not be detected in 1 g or 1 mL of product.
- Lead: not more than 10 mg/kg; arsenic: not more than 2 mg/kg; mercury: not more than 1 mg/kg; cadmium: not more than 5 mg/kg.
- Methanol: not more than 2,000 mg/kg in products containing ethanol or isopropyl alcohol.
- 1,4-Dioxane and free formaldehyde: subject to trace-level control limits in relevant product types.
For products containing preservatives, UV filters, or other restricted substances listed in the national standards, the actual concentration must be verified analytically and must fall within the permitted range. Sunscreen products additionally require confirmation of labeled UV filter content and photostability considerations.
Testing Methods
All mandatory safety tests must follow the official methods published in the Safety and Technical Standards for Cosmetics (2015 Edition). Where no domestic method exists, internationally recognized procedures may be referenced during scientific evaluation. Common analytical techniques and method families include:
- Heavy metal analysis: inductively coupled plasma mass spectrometry (ICP-MS) and atomic absorption spectroscopy (AAS) following microwave digestion.
- Volatile solvent analysis: headspace gas chromatography (HS-GC) for methanol; gas chromatography-mass spectrometry (GC-MS) for 1,4-dioxane.
- Restricted substance and preservative quantification: high-performance liquid chromatography (HPLC) and ultra-performance liquid chromatography (UPLC) with appropriate detectors.
- Microbiological examination: plate count and membrane filtration methods consistent with ISO 21149 for aerobic count, ISO 16212 for yeast and mold, and ISO 21150, ISO 22717, and ISO 22718 for the detection of specified pathogens.
- Sun protection testing: in vivo SPF determination per ISO 24444, in vivo UVA protection factor per ISO 24442, and in vitro UVA-PF per ISO 24443, together with water resistance protocols.
- Toxicological alternatives: validated in vitro methods aligned with OECD test guidelines, such as reconstructed human epidermis models for skin irritation, reflecting the global trend toward non-animal approaches.
Complementary studies frequently performed alongside mandatory testing include accelerated and long-term stability testing, container-content compatibility testing, and preservative efficacy (challenge) testing consistent with ISO 11930. Manufacturing quality is supported by compliance with the ISO 22716 cosmetics good manufacturing practice standard, which is also central to eligibility for certain animal testing exemptions.
Applications
Cosmetics registration and notification testing supports a wide range of regulatory and commercial objectives:
- Domestic notification: filing general cosmetics manufactured in China with the provincial medical products administration before market launch.
- Import notification and registration: submitting general imported cosmetics notifications and special cosmetics registration dossiers through the NMPA platform.
- New ingredient filings: compiling toxicological and safety data packages for new cosmetic ingredients.
- Safety assessment dossiers: generating the analytical and toxicological data required for the product safety assessment report that accompanies every notification.
- Efficacy claim substantiation: providing laboratory, human, or consumer test evidence to support claims such as moisturizing, soothing, firming, oil control, anti-wrinkle, whitening, and sun protection.
- Post-market surveillance: supporting annual reporting, adverse event investigation, and supervision sampling programs.
- E-commerce and cross-border trade: demonstrating product conformity for online marketplaces and preparing brands for eventual general trade registration.
FAQ
What is the difference between registration testing and notification testing?
Notification (filing) applies to general cosmetics and relies on a streamlined testing package focused on microbiological, physicochemical, and core toxicological endpoints. Registration applies to special cosmetics and requires an expanded program that adds human safety trials, efficacy verification such as in vivo SPF testing for sunscreens, and in some cases additional systemic toxicity studies.
Is animal testing always required for imported cosmetics?
No. Since May 2021, imported general cosmetics may qualify for exemption from additional animal testing if the manufacturer holds a compliant good manufacturing practice certificate issued or endorsed by the relevant regulatory authority, the product does not contain new ingredients requiring separate registration, and a complete safety assessment is submitted. Special cosmetics and certain other scenarios remain subject to conventional toxicological requirements.
How long does the testing process take?
Typical turnaround is roughly six to twelve weeks for general cosmetics notification testing, depending on the test battery and microbial incubation periods. Special cosmetics programs, particularly those involving human SPF trials and human safety patch testing, generally require four to six months or longer, especially when seasonal or panel-recruitment constraints apply.
Do test reports expire?
There is no fixed statutory expiration date, but reports must correspond to the final commercial formula, remain consistent with the current version of the national technical standards, and reflect the product actually placed on the market. Any change in formula, manufacturing site, or applicable standards generally necessitates supplementary testing.
Can testing be performed outside China?
Mandatory safety testing for notification and registration must be completed at NMPA-recognized testing institutions within the recognized system. However, certain supporting evidence, such as published literature, formulation-based safety assessments, and some consumer research data, may originate from outside China, provided the documentation meets the acceptance criteria of the review authority.
What information must accompany samples submitted for testing?
Laboratories require the complete ingredient list with percentages, product classification and application area, target user population, production batch details, packaging information, and usage instructions. Accurate classification is critical because it determines the applicable microbial limits, the toxicological test battery, and whether the product is treated as general or special cosmetics.
