<h1>Applicants must document precise input-output proportions for each product; import authorizations and imports must match inputs used.</h1> Standard input-output norms for certain engineering products have been deleted; applicants must now determine and document the proportion of various inputs used or required to manufacture each resultant product. Import authorizations should align strictly with those determinations, and applicants are required to ensure that goods actually imported match the inputs used or required in the exported product. Compliance depends on accurate input-output assessment to justify import-export consistency.
