Input-output norms for umbrellas require imported inputs to match specified component proportions and use in export production.

Input-output norms for folding and straight umbrellas prescribe specific components and standard unit measures for inputs (frames, tubes with specified accessories, ribs of defined types, handles, waterproof nylon cloth, polyester tape), and state that applicants must ensure imported goods are those actually used or required in the exported umbrella product; authorities will determine permissible input proportions and verify correspondence between imports and declared usage.
