Report on the EU UFI Registration Process for Essential Oils
I. Introduction to UFI and Applicability Assessment
The UFI (Unique Formula Identifier) is a 16-character code mandated by the EU under Annex VIII of the CLP Regulation. It is primarily used for Poison Centre notifications prior to placing hazardous mixtures on the market, facilitating the rapid identification of ingredients during emergency medical treatment.
Whether essential oil products require UFI registration depends on their hazard classification under the CLP Regulation. The vast majority of pure essential oils are classified as hazardous mixtures—due to the presence of flammable components (e.g., limonene), skin sensitizers (such as linalool, geraniol, and other substances among the 26 identified by the EU), and hazards to the aquatic environment—and therefore require registration. However, products that are highly diluted and fall below the classification thresholds may be exempt. It is recommended to conduct an assessment using the official classification tools prior to proceeding with registration. II. Core Registration Process
The registration process consists of five stages:
| Stage | Key Action | Remarks |
| ① Qualification Preparation | Confirm EU legal entity (non-EU enterprises must appoint a Only Representative, or OR) | Submission via an OR is accepted in countries such as Germany and France |
| ② Data Preparation | Compile complete formula, SDS, and product classification report | Formula must include concentration ranges and allergen labeling |
| ③ Submission | Submit centrally via the ECHA Submission Portal | Covers multiple national markets in a single submission |
| ④ Fee Payment & Confirmation | Pay required fees to member states and obtain the UFI | UFI is automatically generated by the system based on the company's tax ID |
| ⑤ Label Printing | Print UFI on packaging in the format: UFI: XXXX-XXXX-XXXX-XXXX | Should be placed near the product identification |
III. Checklist of Required Information
The following information must be submitted during the process; all items are mandatory:
1. Basic product information: Name, use category (PC code), packaging specifications, and target market countries
2. Complete formula: CAS numbers, EC numbers, and precise concentration ranges for all ingredients
3. CLP classification information: Hazard categories, H-statements, and pictograms
4. Safety Data Sheet (SDS): Compliant with REACH Annex II standards
5. Corporate qualification documents: EU tax ID, OR authorization letter (if applicable)
If the formula involves trade secrets, a confidentiality protection mechanism may be requested; ECHA allows submission using concentration ranges or alternative names.
IV. Timeline Reference
The UFI is typically obtained within 5–7 working days after online submission; re-notification is required if the formula or classification changes. V. Key Compliance Points
After completion of the process, attention should be paid to the following three points to avoid common compliance risks:
Obligation for timely updates: Notifications must be updated within the prescribed timeframe (generally within 30 days) whenever there are changes to the formula, concentration, packaging specifications, or company information.
Record retention period: All registration documentation must be retained for at least 10 years.
Label consistency: Information regarding the UFI code, product classification, and SDS must be completely consistent across all three.
