BII Shipping Terms

Question: Why does not BII use buyer/Consignee's courier account to ship orders?
BII does NOT use buyer/Consignee courier account to ship because shipping with buyer/consignee's account may cause unexpected issues resulting from various reasons.
If BII shipped goods with buyer/Consignee's courier account, depending on carrier's terms, the carrier may have rights to charge BII (Shipper) if carrier did not receive payment of the shipment from buyer/consignee. The worst case BII experienced was that BII received a surprise bill, which should be paid by consignee’s courier account, from a carrier four months later and BII spent about one year with numerous calls and emails to solve this simple issue caused by Buyer/Consignee and Carrier: Consignee said the bill was paid but can not found the payment proof, Carrier said the bill was NOT paid by Consignee. Finally, BII paid the bill as a discount to buyer’s order.

Sales Tax and Custom Brokerage Services
No Canadian sales tax to international customers. GST or HST is applicable to Canadian customers ONLY.
For international customers: Consignee is responsible to import customs clearance, and pay import duties, tariffs, brokerage fees, taxes imposed by consignee's country and other costs related to shipment.
1. Consignee uses Carrier's brokerage services for customs clearance
. The carrier does import customs clearance and pays import taxes on behalf of consignee. The consignee should release necessary info to carrier for customs clearance and repay or reimburse the carrier and pay the brokerage fees (if any) at time of delivery. The consignee may contact carrier’s local customer service to submit necessary info for customs clearance and on how to repay or reimburse the carrier.
2. Consignee has his/her own custom broker to do customs clearance. Consignee should notify the broker to do customs clearance of the shipment once BII emails consignee the shipment information.
