Standard input-output compliance requires imported inputs to match those actually used in exported engineering products.

Standard input-output norms under the Foreign Trade Policy prescribe quantitative specifications and compliance obligations for cementing float/duplex differential collars, specify material particulars such as seamless casing pipes or equivalent API grade and an extra half inch length allowance, and require determination of input proportions used in manufacture. Applicants must ensure imported goods are those actually used or required in the declared export product.
