Deemed export benefits clarified for suppliers under invalidation letters and AROs; clubbing uses CIF weighted value addition. Against an Invalidation Letter the supplier may avail Advance Authorisation for Intermediate supplies and TED refund where excise exemption is unavailable; against an ARO the supplier is entitled to deemed export duty drawback. For clubbing Advance Authorisations with different prescribed minimum value addition norms, the applicable requirement is the FTP prescribed minimums and the aggregate must be the CIF weighted average of those prescribed minima so the clubbed authorisation meets the weighted average value addition.
