Bond for provisional excise assessment secures compliance with export, special industrial use and payment obligations under Central Excise Rules. A prescribed general bond (with surety or security) secures provisional assessment under Rule 9-B and removal or procurement of excisable goods for export or for special industrial use without payment of full duty. The obligor and surety are jointly liable to the President; missing particulars for provisional assessments must be furnished within the period fixed, and any dues fixed on final assessment must be paid into the treasury within ten days of demand. Surety liability survives forbearance and the President may realize loss from deposited security or by enforcing the bond.
