<h1>Input-output norms compliance required: imported chemical inputs must match prescribed proportions and be used in exported additive.</h1> Standard input output norms under the FTP prescribe the composition per kilogram for the High Base Calcium Phenate additive (SION A1275) and note suspension by Public Notice No. 03/2024-25. The document lists component inputs with mass proportions and mandates that prescribed input proportions be determined and applied in manufacture. Applicants must ensure imported goods are the inputs used or required in the export product and that imported quantities correspond to the manufacturing composition, creating an import use matching obligation.
