Input-output norms govern permitted imports for export manufacture, imposing cement-lining condition and net-to-net accountability for components.

Input-output norms specify permitted inputs and quantities for Ductile Iron Spun Pipes exports; imports are limited to inputs "used or required" in the exported product. Cement imports are allowed only when pipes have cement mortar lining, with other inputs calculated on export weight excluding mortar. Gaskets and lubricants must be imported on a net-to-net basis with accountability and matching specifications. Applicants must ensure imported goods correspond to those actually used in manufacture per the schedule's proportions.
