The rates of duty (including customs duty) and rebate (if
applicable) to be charged are those in force at the time of the
despatch of the oil. Excise duty must be adjusted for any regulator
surcharge or rebate operative at that time.
In the absence of grounds for suspicion of misuse as road
fuel, duty should be called for at the appropriate rebated rate on
the following:
Chargeable deficiencies in oils of other descriptions are to be charged at the unrebated rate.
All chargeable deficiencies are to be brought to account by immediate payment on Form EX601. This includes instances where the explanation for the deficiency is that all or part of the deficiency has been diverted to dutiable use.
If you accept an explanation of an excess deficiency after duty has been paid, as the assessing officer you should reduce or withdraw the assessment using Form EX602. The EX602 should then be sent to Oils Accounting Centre in Southend.
Where it is established that any part of a deficiency has been
diverted to dutiable use a EX601 assessment should be issued as
above. This should be amplified by a demand for payment of duty
(C18) in respect of any customs duty when appropriate.
If the Assurance Manager or Team Leader (Senior Officer)
thinks it is possible that offence action may follow, the duty
should be accepted “without prejudice to the Commissioners
decision as to the subsequent action to be taken”.
