Fee Rate Information

We are committed to providing producers with predictable fee rates and ample notice of changes. Current fee rates are available in the Fees section of the AMS website.

Fee Setting

AMS operates on a cost-recovery basis. If fee revenue exceeds the requirements, then those excess funds will be returned to producers through future fee reductions or adjustments.

Material specific fee rates are calculated using the data sources listed below (subject to quality control processes):

  • Reports received from members on the quantity supplied into the marketplace
  • Budgeted costs for material management activities
  • Budgeted costs for Promotion & Education and Research & Development activities
  • Overhead costs
  • Regulatory charges, if applicable
