EU CLP-PCN-UFI Registration Guidelines for Sealants
I. Background Information
Sealants are classified as mixture products. When placed on the EU market, if they contain ingredients classified as hazardous under the CLP regulation (such as skin irritation, sensitization, inhalation toxicity, etc.), a PCN notification and UFI code must be completed; otherwise, they cannot be legally marketed.
II. Prerequisites for Notification
The sealant has been actually sold or placed on the market within the EU.
The product contains health or physical hazards classified under the CLP Regulation.
The product's Safety Data Sheet (SDS) has been completed.
The product's intended use (consumer use/professional use/industrial use) has been determined.
III. Notification Process (4 steps)
1. Product Hazard Classification Assessment
Classify the sealant's formulation (ingredients, CAS number, concentration) according to the CLP hazard classification.
Identify the hazard categories requiring notification (e.g., skin irritation, eye damage, respiratory sensitization, etc.).
Determine whether the product falls under the mandatory scope of PCN notification for mixtures.
2. Generate a UFI Code
Create a UFI using the UFI generator tool provided by ECHA.
The UFI consists of 16 alphanumeric characters, in the format: XXXX-XXXX-XXXX-XXXX
Each formulation corresponds to a unique UFI code.
3. Submit Notification through the PCN Portal
Log in to ECHA. PCN Submission Portal
Create a company account and complete verification
Fill in the notification information, including:
Product identification information (name, brand, UFI, etc.)
Hazard classification information
Ingredient information (must comply with confidential formulation disclosure rules)
Packaging information
Poisoning Center contact information
Prioritize providing English and the official language version for the target market
4. Labeling and Marketing
Affix the UFI code to the product label.
Ensure that the SDS (Safety Data Sheet) includes UFI information.
Retain the notification certificate for verification by regulatory agencies in EU member states.
IV. Required Documents List
| Document Type | Specific Content
| Product Information | Product name, brand, model, and usage description
| Formulation Information | CAS number, chemical name, and concentration range of each ingredient
| Hazard Classification | CLP classification basis and results
| Packaging Information | Packaging type, specifications, and whether it is child-safe packaging
| Poisoning Center Information | Emergency contact number (must cover target sales member countries)
| SDS Document | Safety Data Sheet Compliant with EU REACH Regulation
V. Precautions
Notifying Entity: Usually the manufacturer or sole representative (OR) within the EU. Non-EU companies must designate an OR to complete the notification.
Notification Validity: Notification information is valid for a maximum of 5 years and needs to be updated regularly.
Formulation Changes: After formula adjustments, a new UFI must be generated and the notification updated (DEZEW Testing CNAS Registration No.: L8083).
Sales in Multiple Member States: If selling in multiple member states, ensure that the notification information covers all target countries.
New Regulation Timeline: Consumer blends are mandatory from January 1, 2021; professional blends are mandatory from January 1, 2024.
