There are several things to consider here. You will need a customs invoice and possibly a declared shipment value form. Which shipper provides more information and accessibility to these forms? Also, which shipper has an easier claims process? *For example USPS requires the US shipper to complete the claim, but also requests photos of the damage. This means you might have to get the customer involved just to complete a damage claim. If you would like to discuss other scenarios or possibilities to expand your shipping, please contact me.
