Associate membership dues are assessed based on annual sales of products, materials, and services, including installation and equipment, to the refractories industry. Sales are calculated FOB at the plant, packaging included.

The sales figure reported should be from the most recently completed fiscal year. Sales data is reported in confidence to the TRI president, using ranges rather than a specific amount. Failure to report sales data in the prescribed manner may result in the maximum dues rate being assessed. Dues are billed in quarterly installments.
