Standard Input-Output Norms require imported polyester inputs to match prescribed input proportions and intended export use.

Standard Input-Output Norms require determination and adherence to input proportions for polyester/polyester blended yarn; applicants must ensure imported goods are those used or required in the export product. The norms specify a material conversion for polyester yarn production and identify PTA as an input equivalence measure. A SION entry for this product has been suspended, and compliance requires matching imports to prescribed input-output proportions and intended export use.
