2) Service charge
a. For orders less than US $5000
Your supplier need to pay a service charge of 1% if they are shipping the order through Alibaba logistics, and 2% if shipping through a third-party vendor. The service charge will be capped at US $100.
b. Orders more than US $5000
Although the supplier will not be charged a service fee, they must use OneTouch as the customs clearance agency to complete the order.
Note: If you were charged more than the pricings listed above, please check if your bank has charged you extra service fees for the transaction.
