The membership fee consists of two components :

  • the REACH cost
  • the membership fee
If you have EU-REACH Registration obligations, you need to pay a single REACH-share cost, plus the yearly membership fee.  If you don’t have EU-REACH Registration obligations, you only need to pay the yearly membership fee, which is based on the global tonnage.  Fees are calculated on the basis of i2a’s operational budget and  the annual tonnage of antimony compounds your company produces or imports.
