Orders that are purchased by individuals or commercial companies are required to pay in advance. Any exception must be approved in writing (fax or contact form) by UTEX before the order can be processed.
Academic or government institutions are requested to pay before their order is processed. However, institutions that maintain separate shipping and billing addresses may pay after receipt of their order. A purchase order number and the address to which the bill should be sent must be provided (preferably by fax) on a business letterhead with the order. Full payment is due within 30 days of receipt of the order.
