Cosmetic Product Formula for Import into Vietnam: Legal Requirements & Best Practices (2025 Guide)

When importing cosmetics into Vietnam, one of the most important documents in the notification dossier is the Letter of Authorization (LOA). This document legally confirms the relationship between a foreign manufacturer or brand owner and the Vietnamese entity authorized to carry out the cosmetic notification process.
In this 2025 guide, Green NRJ explains what the LOA is, why it’s required, how to draft a compliant version, and how to avoid costly mistakes.
What Is a Letter of Authorization (LOA)?
A Letter of Authorization (LOA) is a legal document issued by the manufacturer, brand owner, or product owner. It authorizes a Vietnamese company to represent the foreign business in:
- Submitting the cosmetic product notification to the Drug Administration of Vietnam (DAV)
- Acting as a liaison with Vietnamese regulatory authorities
- Ensuring product safety, quality, and compliance throughout its circulation in Vietnam
Legal Basis
The LOA is required by Vietnamese law and is aligned with regional standards. Its legal foundation includes:
| Legal Document | Description |
| ASEAN Cosmetic Directive (ACD) | Regional regulation implemented in Vietnam |
| Circular No. 06/2011/TT-BYT | Governs cosmetic management by the Ministry of Health |
| Appendix No. 01-MP | Lists documents required for cosmetic product notification, including the LOA |
Required Information in a Valid LOA
A legally accepted LOA must contain all the following:
| Section | Details |
| Authorizing Entity | Name and address of the foreign manufacturer or brand owner |
| Authorized Party in Vietnam | Name and address of the Vietnamese company responsible for submission |
| Scope of Authorization | Clear statement authorizing submission and distribution in Vietnam |
| Product/Brand Information | Specific brand names or product names covered by the LOA |
| Validity Period | Start and end date, or a statement of indefinite validity |
| PIF Commitment | A declaration that the Product Information File (PIF) will be provided |
| Legal Signature | Full name, title, and signature of the legal representative of the authorizing party |
Legalization and Translation Requirements
To be valid for submission, the LOA must go through the following procedures:
- Consular Legalization: The LOA must be notarized and legalized by the relevant Vietnamese diplomatic mission in the country of origin.
- Certified Translation: The LOA must be translated into Vietnamese and certified by a licensed translator in Vietnam.
- Signature Certification: The signature must be that of a legal representative and officially certified.
Common Mistakes to Avoid
Mistakes in the LOA can lead to rejection of the cosmetic notification dossier. The most common issues include:
- Uncertified or unauthorized signatures
- Missing or vague validity period
- Incomplete or outdated company information
- Absence of product list when required
- LOA not properly legalized or translated
Such errors may delay your time to market or result in refusal by authorities.
