Zelvorm Customs
Know what every sale abroad really leaves.
Customs finds each product's HS code, reads the duty from the official UK, EU and US tariffs, and works out the landed cost and profit for every country you ship to, with the EU's €3 rule, the UK's £135 and the end of the US $800 limit built in.
