Export obligation extensions allowed with limited condonation under the EPCG scheme, subject to specified temporal limits. Amendments permit the Assistant Commissioner of Customs to condone shortfalls in export obligation up to five percent and to extend yearwise, blockwise or overall fulfilment periods where the Licensing Authority grants such relief, subject to limits: yearwise extensions only once and for not more than one year within five years; blockwise extensions limited to one two-year block, with the fourth block's extension capped at one year.
