Customers posting items to Guernsey must declare to customs anything other than correspondence.
Of interest, Channel Island residents sending gifts through the post to the UK mainland now have to pay VAT if those gifts are worth more than £36. If the correct VAT has not been paid on an item, the parcel’s recipient must pay the sales tax and a £8 Royal Mail handling charge.
