Input output norms require imported inputs for technical ceramic exports to match declared usage and prescribed quantities. Standard input output norms set permissible inputs and quantities for manufacture of technical ceramic components in steatite and cordierite materials, note a suspension by Public Notice No. 03/2024-25, and list specific raw and auxiliary materials with pack sizes. Applicants must determine and adhere to the proportion of inputs required for the resultant products and ensure imported goods are those actually used or required in the export product.
