I've got a KISS Sport on it's way over from Jetsam
I've just phoned Customs and Excise to get some information on the TARIC Code required. I told them it was diving equipment / breathing apparatus, and they said I should use code 90200000080 which is for 'Breathing appliances and gas masks - other' !
Good news is - the tariff is only 1.7%. Has anyone managed to find an applicable code with lower duty
