Input-output norms require specified components and declared proportions for automobile exhaust catalysts, with import-use verification obligations. Suspension of the FTP entry for automobile exhaust catalysts is recorded and specific input-output norms and component specifications are prescribed. The finished product is a ceramic substrate catalyst impregnated with platinum and rhodium (size 93 mm dia x 95 mm) with declared precious metal contents. Permissible inputs are itemised - the specified ceramic substrate, platinum as tetramine platinum chloride, and rhodium as rhodium nitrate - and applicants must determine input proportions and ensure imported goods are those used in the export product.
