Input-output norms for porcelain articles require imported inputs to match declared use in export products.

Standard input-output norms for porcelain articles designate a one-kilogram finished-product standard and prescribe constituent inputs and proportions-china clay, ball clay, and transfers for decorative use-with transfers allowed only for decorative purposes. Applicants must ensure imported goods correspond to inputs actually used or required in the export product and bear responsibility for demonstrating that imported inputs match declared usage.
