Generally, customers shall purchase products by issuing a written purchase order signed by an authorized representative, indicating product names and descriptions, quantity, price, total purchase price, shipping instruction, requested delivery date, bill-to and ship-to addresses, tax exempt certifications if applicable, and any other special instructions and information.

Or customers can just confirm our proforma invoice instead of issuing the purchase order, on our proforma invoice sent to the customers, we will also list product names and descriptions, quantity, price, total purchase price, shipping instruction, requested delivery date, bill-to and ship-to addresses, tax exempt certifications if applicable, and any other special instructions and information.

The agreed proforma invoice and/or agreed purchase order will be regarded as the sales contract. The customers can also require other ways of establishing the sales contract in their preferred  manner.
