<h1>Input-output norms govern permitted imported components and require imported goods to match declared export product use.</h1> Standard input-output norms prescribe allowed imported components for an outdoor 600/1000 V overhead cable termination kit by listing constituent inputs and quantities. Applicants must determine proportions of inputs used across resultant products and ensure imported goods are those actually used or required in the declared export product, enabling administrative verification that imports match end use in export manufacture.
