We will ask you for the following documentation for shipping an item that you've bought or sold:  

• Confirmation of shipper and recipient information, including in-country phone numbers.
• Copy of your sales receipt (such as a bike shop receipt, screenshot of eBay auction close or PayPal transaction) that describes the contents and displays the purchase price of the item(s) in your shipment. We can also accept a signed and dated written statement that details the items being shipped, their values and the involved parties. The amount on your sales receipt for the item(s) you’re shipping must exactly match the market value entered for your shipment.

Your shipment will be classified as a “Commercial” shipment. Duties, taxes & fees are calculated while placing your order on our website.
