VPDS051300 | Vaping Products Duty and Vaping Duty Stamps: Approvals - general: Transfer Of a Going Concern (TOGC): New owner requirements
From HM Revenue & Customs · Vaping Products Duty and Vaping Duty Stamps guidance
Before carrying out any manufacturing or duty representation, the new owner must:
obtain the necessary approval before the transfer
meet the fit and proper criteria
provide any required financial security
Normally the trader should apply at least 45 days before the required approval date in order to ensure that HMRC have adequate time to assess and work the application and you should aim to issue the approval within this time period, however it may be that it takes longer than this if there are delays in obtaining information from the trader, for example.
