<h1>Input-output norms require imported components to match declared export composition and allow specified net-to-net treatment.</h1> Standardised input-output norms list specific hydraulic cylinder components as eligible for net-to-net treatment and specify steel tube input content relative to the export product. The schedule mandates determination of proportions of inputs used in manufacture and requires applicants to ensure imported goods correspond to those used or required in the export product, creating an evidential obligation to substantiate input usage and proportions against declared export composition.
