Input-output norms govern permissible imported input composition for furniture exports and require imports to match used export components. Input output norms set the permissible composition and proportion of imported inputs for ready to assemble and modular furniture exports, listing specific inputs with measurable content metrics (area, weight or FOB linked percentages), wastage allowances and net to net treatment. Applicants must ensure imported goods correspond to those used or required in the declared export product, and determination of proportions for manufacture follows the published schedule.
