Does anyone know the how customs taxes and duties are calculated? I can’t seem to find a calculator or chart or brackets anywhere. I called DHL and they said they don’t know anything about it and it’s at the government’s discretion. How does that even make sense? I understand under $800 there is no duty. In the past I paid $150 on a bag that costed $1500. I’m wondering how much duties I will pay on a $3000 bag from the U.K.
