NTIS now offers direct and secure ordering via the World Wide Web. A product that can be ordered from NTIS via the Web will feature an order button on its Web page. Learn more at our ordering products page. NTIS electronically stores our collection of well over 2 million items and custom-reproduces a single copy specifically for your order. Therefore, NTIS does not accept cancellations, requests for modifications, or returns for credit or refund.
All sales are final.
Use our order verification page to do this. When you place an order by telephone, please have the product order number and title ready. Also, you will need an NTIS deposit account number or number of a major credit card as method of payment. Once your order is placed, it cannot be canceled because it is immediately put into our automated processing system. Representatives in our Customer Service Department will gladly assist you.
