<h1>Input-output norms require imported materials to correspond to manufacturing inputs, ensuring imports are actually used in export products.</h1> Standard input-output norms for Eugenol/Iso Eugenol (SION A2162) specify the permissible proportional relationship between imported inputs and resultant export products (example: 1 kg corresponds to 1.10 kg Clove Leaf Oil). The schedules require determining proportions of inputs usable or required in manufacture and oblige applicants to ensure that imported goods are those used or required in the export product, emphasizing proportionality and verification of actual use.
