Input-output norms for PVC power cables: import of specified inputs allowed subject to component proportion limits and use-for-export verification. Standardised input-output norms permit specified primary metal inputs and either PVC compound or its constituent inputs for manufacture of PVC insulated power and LT PVC cables. If PVC compound is replaced, permitted quantities are allocated among PVC resin, plasticizer, and filler in prescribed proportions; PVC stabiliser may be allowed up to a limited share subject to a reduction in resin allocation. Import quantities must follow the Engineering product tables and applicants must ensure imported items are those actually used in the export product.
