<h1>Deletion of SION C804 requires proving imported inputs match exports and determining allowable input proportions for manufactured products</h1> The schedule records deletion of the prescribed standard input-output norms entry for engineering products (SION C804) and requires determination of allowable proportions of various inputs used to manufacture different resultant products; applicants must verify that goods proposed for import and actually imported are those necessary for the export product. The obligation focuses on ensuring imported inputs correspond to and are used in the exported manufacture, with enforcement tied to compliance with the now-deleted SION provision.
