The UFI code: rapid aid in an emergency

As of January 2026, chemical products such as cleaning agents, paints and adhesives that pose health or physical hazards must carry a unique formula identifier (UFI) in Switzerland. In an emergency, medical professionals can use the UFI to quickly determine the composition of the product and take the necessary measures immediately.

In the event of poisoning

Call Tox Info Suisse on the emergency number 145

What is the UFI?

The unique formula identifier (UFI) is a 16-character code consisting of letters and numbers that must be indicated on the label of hazardous chemical products. The code uniquely identifies the composition of a chemical product.

Example “UFI: N1QV-R02N-J00M-WQD5”

What is the UFI used for?

In the event of poisoning, the UFI code enables the Tox Info Suisse poison information centre (tel. 145) to immediately see which substances are contained in the product and recommend the necessary medical measures to the doctor treating the patient.

Where can the UFI be found?

The UFI code is usually printed clearly, legibly and indelibly on the chemical product, preceded by the acronym “UFI” in capital letters.

What products require a UFI?

In Switzerland and the EU, the UFI is required for all products that are classified as hazardous owing to the health or physical hazards they pose (hazard statements H3xx or H2xx).

This includes:

  • Preparations (mixtures) such as cleaning agents and adhesives
  • Biocidal products such as disinfectants
  • Fertilisers
  • Plant protection products
  • Tobacco products (refill containers with e-liquids)

Who is responsible for creating the UFI and reporting it to the Chemicals Product Register?

For products that are only marketed in Switzerland and not in the EEA, the respective distributor is responsible (Swiss manufacturer, Swiss importer or Swiss licence holder). They can generate the UFI using the official UFI generator and their Swiss VAT number. They must also specify the UFI when registering with the Federal Chemicals Product Register (RPC).
