Decode UFI (Unique Formula Identifier) codes to reveal company VAT numbers and formulation details. Extract the underlying information used for poison centre notifications.
Enter a 16-character UFI code with or without dashes
Decode UFI codes to reveal the underlying formulation numbers assigned by companies to each unique mixture
Extract VAT numbers and retrieve company name and address from the EU VIES system for VATIN-type UFIs
Verify that the correct VAT number and formulation code were used when generating UFIs for CLP compliance
A UFI (Unique Formula Identifier) is a 16-character alphanumeric code required on labels of hazardous chemical mixtures under EU CLP Regulation Annex VIII. It links a product to its poison centre notification, enabling toxicology centres to quickly identify the mixture composition during emergency calls. The format is XXXX-XXXX-XXXX-XXXX and must be preceded by "UFI:" on the label.
The decoder reverses the UFI algorithm (as documented in the ECHA UFI Developer Manual) to extract the VAT number and formulation code. For VATIN-type UFIs, it also queries the EU VIES system to retrieve the company name and address. No product composition or classification data can be decoded from a UFI — that information is only held in the poison centre notification system.
VATIN — UFI codes generated using a European VAT number. These allow full company lookup including name and address through the EU VIES system. Most UFIs in circulation are this type.
COMPANY_KEY — UFI codes generated using a numeric company key instead of a VAT number. These provide limited information since company keys cannot be looked up in public registries.
The decoder is useful for verifying that the correct VAT number was used in a UFI, identifying which company created a UFI code found on a product label, checking the formulation number to track product versions, and auditing UFI codes across your product portfolio.
