Standard Input-Output Norms for FR 4 laminates require imported inputs to match those actually used in the export product.

Standard Input-Output Norms prescribe specific material inputs and allowable quantities for manufacture of Copper Clad Glass Epoxy Laminate (FR-4) 1.6 mm single- or double-sided, listing copper foil (separate single/double quantities and weights by foil thickness), glass fabric, brominated bisphenol epoxy resin, thinners/solvents, hardeners, accelerators, release film and padding paper per 100 sq.mt. A compliance provision requires determination of input proportions for resultant products and mandates that applicants ensure imported goods are those actually used or required in the export product.
