E Astle

Scenario If we are to start supplying new tyres to a customer in NI who will be fitting the tyres to new trailers and selling the trailers do we have to guarantee the trailers will not be sold in the EU or because the tyres are now fitted to a trailer is this a change in commodity and something we no longer have to worry about regarding being at risk, we can get a letter from the customer saying they will not wholesale the tyres and that they are just for fitting to new trailers. Can we use the UK Internal Market scheme and state these tyres as not at risk?
