Submitting a cosmetic notification (filing for ordinary cosmetics or registration for special cosmetics) to China’s National Medical Products Administration (NMPA) is a complex process. According to NMPA data, a significant percentage of applications are returned for corrections – causing months of delays and additional costs. The most common NMPA notification rejection reasons often stem from preventable errors in documentation, formulation, labeling, or testing. Understanding these pitfalls and knowing how to fix them can dramatically increase your chances of first‑time approval. This guide covers the top rejection reasons and provides actionable solutions.
1. Incomplete or Inconsistent Documentation Dossier
The NMPA requires a comprehensive dossier for both filing and registration. Missing or inconsistent documents are a leading cause of rejection. Common issues include:
- Missing product formulation disclosure: The full quantitative composition (including all ingredients, their concentrations, CAS numbers, and INCI names) must be provided. Many applicants omit trace ingredients or fail to declare the exact percentage ranges.
- Inconsistent information across documents: The product name, manufacturer address, or ingredient list on the application form, free sale certificate, and label must match exactly. Any discrepancy triggers a rejection.
- No valid free sale certificate (FSC): For imported cosmetics, an FSC issued by the competent authority of the country of origin is mandatory. The FSC must explicitly state that the product is legally sold in that country. A generic manufacturing license is insufficient.
- Missing power of attorney (POA): The POA authorizing the Chinese agent to submit the application must be notarized and legalized (or apostilled, depending on the country) and accompanied by a certified Chinese translation.
How to fix: Before submitting, create a document checklist based on the NMPA‘s official requirements for your product category. Have a second person (or a regulatory consultant) cross‑check all documents for consistency. Ensure the FSC includes the exact product name and manufacturer name as used in the application. For the POA, use a template approved by NMPA and ensure it is notarized and translated correctly.
2. Ingredient Compliance Issues – Disallowed or Problematic Components
Ingredient‑related rejections are among the most common and complex. Key problems include:
- Use of prohibited substances: Certain ingredients are banned under the Safety and Technical Standards for Cosmetics (STSC), including specific preservatives (e.g., certain parabens beyond permitted levels), colorants, and UV filters. Even trace contaminants may be flagged.
- Exceeding maximum permitted concentrations: For restricted substances (e.g., salicylic acid, certain preservatives like phenoxyethanol), the concentration must be within STSC limits. Many foreign formulations exceed Chinese limits.
- New cosmetic ingredients without proper filing: If your formula contains a novel ingredient not listed in IECIC, it must be registered as a new cosmetic ingredient (with a three‑year safety monitoring period) before the product can be filed. Many applicants mistakenly assume that IECIC coverage extends to derivatives or plant extracts not explicitly listed.
- Ingredient name mismatch with IECIC: The INCI name or Chinese name must exactly match the Inventory of Existing Cosmetic Ingredients (IECIC). Recent IECIC updates have standardized many names (e.g., botanical taxonomy corrections). Using an outdated name leads to rejection.
- Nanomaterials not declared: If any ingredient is in nano form, it must be explicitly declared and comply with specific safety assessment requirements. Undeclared nanomaterials cause automatic rejection.
How to fix: Conduct a full ingredient review against the latest STSC prohibited/restricted lists and IECIC. Use official NMPA databases to verify each component. For borderline ingredients, consult a toxicologist. If a new ingredient is required, file it separately (allow 6‑12 months). For name mismatches, update the dossier to use the IECIC standardized name. Perform quantitative analysis to confirm concentrations meet limits.
3. Labeling Errors – Missing or Improper Information
The submitted label artwork (must be in Chinese) is carefully reviewed. Common rejection reasons include:
- Missing mandatory elements: The label must include product name, registration/filing number, full ingredient list, net content, manufacturer and importer information, production date and expiry date, instructions for use, and applicable warnings. Missing any item triggers rejection.
- Incorrect date format: Production date and expiry date must be in “YYYY‑MM‑DD” or “YYYY年MM月DD日” format. Other formats (e.g., “MM/YYYY”) are not accepted.
- Ingredient order wrong: Ingredients must be listed in descending concentration. Incorrect ordering (e.g., placing a minor preservative before the main base) is a common error.
- Warnings missing for specific product types: For example, hair dyes must include an allergy patch test warning; alpha‑hydroxy acid products must include sun sensitivity warning; products for children must include adult supervision statement.
- Misleading claims: Claims such as “organic”, “natural”, “hypoallergenic” without substantiation or “therapeutic” statements (e.g., “treats acne”) are prohibited. Only NMPA‑approved efficacy claims (e.g., whitening, sunscreen) may appear.
How to fix: Use an NMPA‑approved label template. Have the artwork reviewed by a compliance specialist before submission. Ensure the ingredient list is derived directly from the formulation disclosure and sorted by concentration. Remove any unsubstantiated claims. For products with special warnings, consult the relevant technical specifications.
4. Inadequate or Invalid Test Reports
NMPA requires test reports from qualified laboratories (CNAS‑accredited or NMPA‑designated) for specific tests, depending on product type. Common issues:
- Missing required tests: Ordinary cosmetics require microbiological tests, heavy metal tests, and risk substance tests. Special cosmetics (e.g., sunscreen, whitening) require additional efficacy tests. Many applicants omit mandatory items.
- Test reports from unaccredited labs: Only reports from CNAS or NMPA‑recognized laboratories are accepted. Reports from foreign labs without CNAS accreditation (even if ISO 17025) are generally rejected.
- Sample not representative: The tested sample must match the formulation submitted. If the lab tested a different batch or formula (e.g., without preservatives), the report is invalid.
- Expired test reports: Test reports older than 3 years (or 1 year for certain stability tests) are not accepted.
How to fix: Before commissioning tests, confirm the exact testing requirements with an NMPA‑accredited lab. Use the same batch/sample for all tests. Keep test reports up to date – for long development cycles, repeat tests as necessary. Choose a lab that is familiar with NMPA dossier requirements.
5. Efficacy Claim Evidence – Insufficient or Non‑Compliant
For special cosmetics (whitening, sunscreen, anti‑hair loss, anti‑acne, etc.), efficacy claims must be supported by robust evidence. Common rejections:
- No efficacy test report: A claim without supporting data is automatically rejected.
- Test protocol not compliant with NMPA guidelines: For whitening, in‑vivo human trials with specific parameters are required. Using only in‑vitro tests leads to rejection.
- Claim wording not approved: Only specific wording allowed (e.g., “whitening” or “lightening skin tone” – no superlatives like “instant whitening”).
- Evidence submitted for a different product variant: If you have multiple shades or versions, each must have its own evidence or a bridging study.
How to fix: Refer to NMPA‘s “Guidelines for Efficacy Evaluation of Cosmetics” (2021). Engage a CNAS lab that specializes in efficacy testing. Submit the full test report (raw data, statistical analysis, signed declarations). Use only approved claim wording – consult a regulatory expert.
6. Overseas Manufacturer Qualification Issues
For imported cosmetics, the overseas manufacturer must be properly registered. Rejection reasons include:
- Manufacturer not registered with NMPA under the new “Responsible Person” system.
- Good Manufacturing Practice (GMP) certificate missing or not recognized: China does not automatically accept foreign GMP certificates; the manufacturer must self‑declare compliance or provide a recognized GMP audit.
- Inconsistency between the dossier and the actual manufacturer address or name.
How to fix: Ensure the manufacturer completes the GAC registration for overseas food/cosmetic enterprises. Provide a GMP certificate (ISO 22716 or equivalent) with a notarized translation. Double‑check that all documents use the exact same name and address.
7. Rejection Case Study – Whitening Serum Filing
An imported whitening serum was rejected three times before approval. The first rejection: missing efficacy test report (the applicant submitted only a literature review). The second rejection: the efficacy test used 10 subjects, but NMPA requires at least 30 for whitening claims. The third rejection: the claim wording “freckle removal” was not approved; “whitening” was the allowed term. After correcting each issue, the product was finally registered. Total delay: 14 months.
