Utilisation deadlines for duty-free imports require installation or use or duty and interest may be payable; extensions granted liberally. Under the 100% EOU scheme, capital goods must be installed within one year and raw materials utilized within three years unless extensions are granted; goods produced must be exported or disposed under FTP within one year. Non-compliance attracts duty and interest. EOUs should apply for warehousing extensions in advance; CBEC guidance prescribes liberal grant of extensions, restraining duty/interest demands to mala fide diversion cases, and Circular No. 7/2005-Customs requires warehousing extensions for capital goods to be co-terminus with the LOA and warehousing licence.
