Applications for credit of customs or excise duty paid in error may be allowed if made within 3 years of duty payment AND if,
Except as above or as specifically provided elsewhere in this
guidance,
no cognisance should be taken of mineral oil after
delivery on payment of duty and
no credit of duty should be allowed.
If application is made for repayment of duty on the grounds
that the oil has been lost or destroyed after payment of duty, the
applicant should be informed that the oil has passed out of
official charge and no further official cognisance can be taken of
it.
Similarly a belated claim for rebate on oil delivered at the
full rate of duty on the grounds that un-rebated oil was ordered
and/or delivered in error and was used for purposes for which
rebated oil could have been properly used should be rejected.
