Deemed export benefits: procedural rules for claiming drawback and terminal excise refunds, documentation and payment conditions. Deemed export claims require ANF 8 with prescribed documents and supplier or recipient certifications; claims must be supported by proof of payment through normal banking channels or proof of supply and filed within the statutory period. TED refund is tied to physical supply and receipt of substantial payment while drawback is limited to the amount of payment received. Where All Industry Rates are inadequate, applicants may seek brand rate fixation and provisional payments may be allowed pending fixation. Sub-contractors may claim benefits for goods manufactured or properly outsourced, and interest on delayed refunds is payable without a separate application.
