Standard input-output norms require specified input proportions for phenol formaldehyde resin and importer compliance with export use. Standard input-output norms under the Foreign Trade Policy prescribe component proportions for Phenol Formaldehyde Resin Solid/Lumps: one kilogram of phenol and 0.28 kilogram of paraformaldehyde per kilogram of finished resin. The schedule requires determination of allowable input proportions and imposes an obligation on applicants/importers to ensure imported goods match the inputs used or required in the declared export product.
