OT05335 | PRT: valuation of crude oils and products - category 2 oils introduction
From HM Revenue & Customs · Oil Taxation Manual
The difference between the two categories is that Category 2 oils do not have published and widely available price reports.
The list of oils currently within Category 2 can be found at OT05343. They are generally grades which;
have smaller volumes than Category 1 oils, and\or
are grades with unique properties that mean they are only used by a small number of users; so-called “niche grades”, and\or
are offshore loaded, and\or
have some other unique feature.
Consequently the way they are sold commercially varies enormously from kind to kind. The only practical way to calculate market values is on a “case-by-case basis”, crafting a method that fits the kind of oil in question to reflect, as far as practically possible, the unique features of that kind of oil’s usual sales contracts.
