Vietnam’s Cosmetic Ingredient Compliance: Proven Methods to Easily Check Ingredients Before Importing 2026

Introduction

Cosmetic ingredient compliance is a critical requirement when importing cosmetics into Vietnam, going far beyond simply sourcing suppliers and arranging logistics. In practice, every product must undergo a mandatory notification procedure before being placed on the market. During this process, the regulatory authority reviews the full ingredient list to ensure compliance with both Vietnam’s regulations and the ASEAN Cosmetic Directive.

Failing to verify ingredient compliance is one of the most common, and costly, mistakes businesses make. In many cases, the risks extend far beyond procedural issues and can result in serious consequences, including delays in customs clearance, administrative penalties, mandatory product recalls, and long-term damage to brand reputation.

Therefore, ensuring cosmetic ingredient compliance from the outset is not only a legal requirement but also a key factor in how efficiently products can be brought to market. In this article, Green NRJ provides a clear and practical guide to checking cosmetic ingredients before import, helping businesses proactively minimize risks and streamline their market entry process.

Overview of Vietnam’s Legal Framework for Cosmetic Ingredient Management

Vietnam regulates cosmetics through a combination of regional frameworks and domestic regulations, forming a relatively stringent control system. In practice, businesses are required to comply simultaneously with the ASEAN Cosmetic Directive (which establishes harmonized rules across member states), regulations issued by the Drug Administration of Vietnam under the Ministry of Health, as well as additional requirements related to labeling, advertising, and product claims.

From an ingredient perspective, there are three core principles that businesses must carefully observe. First, ingredients listed as prohibited under ASEAN regulations must not be used under any circumstances. Second, restricted ingredients are only permitted when all specified conditions are fully met, including maximum concentration limits, defined usage areas (for example, use on skin but not in the eye area), and mandatory labeling requirements. Third, products must not contain hazardous impurities exceeding permitted limits, particularly heavy metals.

In practice, this means that ingredient assessments should be conducted as early as possible, ideally before entering into any agreement with a supplier.

The INCI List in Cosmetics: Why Businesses Need to Understand It When Checking Ingredients

The INCI system (International Nomenclature of Cosmetic Ingredients) is a globally recognized naming convention used to standardize the identification of cosmetic ingredients, ensuring consistency and transparency in both product declaration and regulatory review.

From a compliance perspective, the INCI system plays a critical role. First, it is a mandatory requirement under Vietnamese regulations, as businesses must declare all ingredients using their correct INCI names. Second, it serves as the basis for regulatory assessment, with product safety evaluated according to INCI names rather than trade or marketing names. In addition, a clear and accurate INCI list enhances transparency, thereby strengthening consumer trust.

For example, a product marketed as a “whitening serum with natural extracts” is still required to disclose its specific ingredients in accordance with the INCI system, such as ascorbic acid (vitamin C), niacinamide, or arbutin. The use of vague terms like “natural whitening agents” without clearly identifying the actual ingredients is not acceptable and may result in the product being deemed non-compliant or the application being rejected.

Classification of Cosmetic Ingredients under the ASEAN Cosmetic Directive

According to the ASEAN Cosmetics Directive, cosmetic ingredients are classified and regulated through specific annexes, each clearly defining the scope and conditions of use:

• Annex II: List of substances prohibited in cosmetic products
• Annex III: List of substances permitted with restrictions
• Annex IV: List of approved colorants
• Annex VI: List of permitted preservatives
• Annex VII: List of approved UV filters

During the review process, businesses should focus on two key areas: completely eliminating ingredients listed in Annex II and strictly complying with the conditions of use for those listed in Annex III.

A Step-by-Step Guide to Checking Cosmetic Ingredients Before Import

Step 1: Obtain a Complete INCI List

Businesses should request that suppliers provide the full product formulation, including the exact INCI names of all ingredients and their corresponding concentrations (expressed as a percentage by weight). It is important to note that providing only trade names is not acceptable; all ingredients must be disclosed, including minor components such as preservatives and fragrances.

If the manufacturer has concerns regarding confidentiality, businesses may enter into a confidentiality agreement to protect the formulation while still meeting regulatory compliance requirements.

Step 2: Check for Prohibited Ingredients

Businesses should cross-check the entire ingredient list against Annex II. If any ingredient listed in this annex is identified, the product will be deemed non-compliant and will not be permitted for import, with no exceptions. Typical examples include mercury compounds (except in specific cases), clobetasol propionate, hydroquinone (except for restricted professional use), chloramphenicol, and lead compounds.

It is important to note that many prohibited substances may appear under different chemical names. Therefore, businesses should also verify ingredients using their CAS numbers to ensure accuracy in the assessment process.

Step 3: Evaluate Restricted Ingredients

For ingredients listed in Annex III, compliance depends on specific conditions of use, including maximum concentration limits, permitted areas of application, and mandatory labeling requirements. For example, salicylic acid is permitted at a maximum concentration of 2%; exceeding this limit or failing to include the required warnings may result in the product being deemed non-compliant. Similarly, resorcinol is only permitted for use in hair dyes, while phenoxyethanol is limited to a maximum concentration of 1.0%.

Even minor deviations from these requirements may lead to the application being rejected.

Step 4: Verify Purity and Impurities

Compliance is not determined solely by the ingredient list but also depends on the quality of the raw materials used in the product. Businesses must ensure that heavy metal levels remain within permissible limits and that raw materials are free from hazardous impurities that may arise during the manufacturing process.

To manage these risks, businesses should request Certificates of Analysis (CoA) from suppliers and conduct microbiological testing where necessary.

Step 5: Check Special Ingredient Categories

Where a product contains specific categories of ingredients such as colorants, preservatives, or UV filters, businesses must refer to the relevant annexes to ensure full regulatory compliance. In particular, it is essential to verify that the concentration of each ingredient falls within permitted limits and that its intended use aligns with the product’s application.

Key References

To ensure accuracy in ingredient verification and assessment, businesses should rely on up-to-date and reliable sources, including the latest version of the ASEAN Cosmetic Directive, regulations and guidance issued by the Drug Administration of Vietnam, the EU CosIng database (for reference purposes only), and cosmetic ingredient safety assessment reports.

As these regulations are frequently updated, relying on outdated information remains a common compliance risk that businesses should be particularly aware of.

Common Mistakes and How to Avoid Them

During the cosmetic import process, businesses often encounter several common pitfalls, such as relying on marketing claims without verifying the actual ingredient composition, overlooking minor ingredients even in small quantities, or using outdated regulations during the evaluation process.

To mitigate these risks, businesses should conduct independent verification, require full disclosure of all ingredients, and stay up to date with the latest regulatory requirements. Alternatively, engaging a professional consulting firm can help ensure full compliance.

Frequently Asked Questions (FAQ)

• Is it acceptable to use the EU CosIng database?

Yes, it can be used as a reference. However, the final assessment must be based on the ASEAN Cosmetic Directive and Vietnam’s regulations.

• If an ingredient slightly exceeds the permitted limit, can it still be accepted?

No. Any deviation, regardless of how small, is considered non-compliant and may result in the application being rejected.

• What if an ingredient is not listed in any of the annexes?

In such cases, the ingredient may still be accepted if its safety can be demonstrated. However, businesses must prepare comprehensive technical documentation to support the evaluation process.

Conclusion

Ensuring compliance with cosmetic ingredient requirements is not only a legal obligation but also a critical foundation for building sustainable business operations in Vietnam. By implementing a systematic verification process, including comprehensive ingredient data collection, cross-checking against the annexes of the ASEAN Cosmetic Directive, controlling the quality and safety of raw materials, and relying on up-to-date regulatory references, businesses can proactively mitigate risks and confidently bring their products to market.
