The membership fee consists of two components :

  • the REACH cost
  • the membership fee

If you have REACH obligations, you need to pay a single REACH-share cost, plus the yearly membership fee depending on the annual tonnage of antimony compounds your company produces or imports.

If you don’t have REACH obligations, you only need to pay the yearly membership fee, which is based on the global tonnage.

Advantages of i2a membership
