For US customers orders are shipped from our warehouse in New Jersey. That means your order will not be charged and customs or import fees. You may however be charged state tax if you are based in New Jersey.
For all Non-EU countries most orders shouldn't be charged customs as most are below the minimum threshold. This amount may vary from country to country and these fees are the responsibility of the customer. We ship your package DDU, "duties and taxes unpaid", and we do not collect the VAT, duties and/or taxes and cannot predict what your particular charges may be. If your order does require these additional charges, they must be paid by you in order for your package to clear customs.
