If the total value of your order (before any discounts) is more than $800 you will be charged customs and duties - you will be reminded of this at the checkout.
Our delivery partner (DHL) will contact you directly once they have your parcel to collect the payment. They usually get in touch via email, but may also send a bill through the mail if you don't respond. You can also manage your shipment proactively on the DHL On Demand Delivery site.
Amounts do differ by state, so if you want to confirm exact costs before you order it's best to contact US customs.
It is a legal requirement that we declare the full value of the contents of all packages, so please do not request that we send a parcel without this.
