Establishing the biodiesel content of bioblend after the duty point

During the meeting of the Biofuels Working Group on 23 January 2008 HMRC agreed to provide a ‘pecking order’ of acceptable evidence to determine the biofuel content of bioblend delivered to home use and on which excise duty has been paid (Action point 4).

Suggested methods for determining the quantity of biodiesel present in bioblend, which is marked at remote marking premises following delivery to home use on payment of duty, are set out below. It is essential to establish a procedure to ensure:

  1. that rebate claims (HO9s) reflect the lower duty rate applicable to the biodiesel element
  2. that the calculation of any claim does not become overly complicated and burdensome

HMRC accept that some flexibility is essential in order to achieve practical procedures. Therefore, it is recommended that similar procedures, to those proposed in respect of 'slops', should be adopted:

  1. Where Automotive Gas Oil (AGO) is marked at an RMP, and there is an audit trail to show the biodiesel content (ie it can be traced to a particular production source), the producer’s blend ratio for the duty period during which the original duty payment occurred may be used.
  2. Where AGO is marked at a RMP, and there is no audit trail to show the biodiesel content, the assumption will be that the AGO has been blended to the limit (5%).
  3. HMRC’s understanding is that companies will not, as a matter of routine, seek to use biodiesel in the production of an IGO blend. Where Industrial Gas Oil (IGO) is marked at a duty-paid terminal the assumption will be that there is no biodiesel component.
  4. However, IGO may, exceptionally, be blended with biodiesel and subsequently marked at an RMP. In these circumstances, where an audit trail shows that biodiesel has been blended with IGO, the ratio should be determined by reference to the particular blend. Where this is not possible the ratio per b) or e) will apply.
  5. Where IGO or AGO are marked at an RMP, and there is uncertainty as to the biodiesel content, this may be established by laboratory analysis. Where this option is used the results of analysis may be taken to provide the basis for claims.

HMRC will not be prescriptive as to the nature of the documents required. Any documentation, commercial or official, will be acceptable provided it is sourced from the originator, eg the producer of the bioblend, the laboratory conducting the analysis or other reliable source, and there is no reason to doubt the validity of the documentation.
