VPDS072000 | Vaping Products Duty and Vaping Duty Stamps: Manufacture: Definition of manufactured
From HM Revenue & Customs · Vaping Products Duty and Vaping Duty Stamps guidance
A vaping product is considered to be manufactured if:
a liquid or substance that hasn't had duty paid on it which is:
mixed with another substance (even if this is duty paid)
changed or processed in some way
and the result is a vaping product
If a liquid that hasn't had duty paid has any of the following properties:
packaged
given a label
advertised in a way that shows it's meant to be used in a vape
Then that act of packaging, labelling, or advertising is also treated as manufacturing a vaping product. It is important to note that some limited forms of production (for example, relabelling) are allowable outside of a manufacturer’s approved premises.
When we talk about a substance or liquid that hasn't had duty paid, we mean it's either:
not yet a vaping product
it is a vaping product, but the duty hasn't been paid or has been deferred under a duty deferment arrangement
This is defined in section 117 of FA26.
