AIR4150 | Alcoholic Ingredients Relief: Technical guidance: Are losses allowable under the AIR regime?
From HM Revenue & Customs · Alcoholic Ingredients Relief
Yes. But, the claimant must record in his records:
losses in storage;
accidental losses in process;
investigations into the losses, including any management decisions taken, and
report more serious losses and deficiencies.
You should agree with the claimant a level at which a loss should be reported. Obviously, a large loss for one company will be negligible for another.
Any losses for which the claimant cannot provide a satisfactory explanation should not be repaid.
