Apply for a permit to use group B chemical substances

You must have a permit to handle certain carcinogenic, sensitising or reprotoxic substances, group B substances.

Permission is needed for substances in group B

As an employer, you need to apply for a permit to handle chemical substances in group B.

You do not need a permit to stock, sell or transport unbroken original packaging containing group B substances.

If you handle substances in group B without a permit, the Swedish Work Environment Authority may decide that you must pay a sanction penalty fee.

Apply for a permit

You apply for a permit at the Swedish Work Environment Authority. Keep in mind that:

  • we usually do an on-site inspection before the permit can be given.
  • our processing time for permits is approximately three months. Apply in good time.

How to apply

  • 1. Fill out the application form

    The application form is available in Swedish only. You will need to fill out information such as

    • name of the substance or product that you will handle
    • CAS number of the substance or product
    • your methods
    • the reason for handling the substance
    • the time period for which the permit should be valid
    • the quantity of the substance that you will have and use
    • the number of people involved

    3. If we don't change our decision, we will refer your appeal to a court of law
      If the Swedish Work Environment Authority stands by its first assessment not to grant a permit, we will refer your appeal to a court of law, in this case the Administrative Court. We will also send your application and all other documents in your case.
