<h1>Input-output norms govern permissible import content for manufacturing export riding breeches under foreign trade policy controls.</h1> Input-output norms prescribe the component inputs and their permitted proportions for men's and ladies' riding breeches with full seat of artificial leather, listing relevant fabric, artificial leather content by weight, hook fasteners as a set, and zips. The schedules require determination of proportions of inputs usable or required in manufacture, and applicants must ensure imported goods are those actually used or required in the export product, conforming to prescribed composition and net-to-net accounting.
