Input-output norms require specified pharmaceutical composition and verified input proportions for export compliance. Standard input-output norms under the Foreign Trade Policy set the authorised composition, packaging and input quantities for an Amoxicillin & Clavulanic Acid suspension, specifying per-bottle active-equivalent content, permitted packaging size, batch quantity and measured input weights for Amoxicillin trihydrate and diluted potassium clavulanate. A schedule prescribes determination of allowable input proportions for manufacture, and applicants must ensure imported goods are those used or required in the declared export product.
