Payment and Billing for USP Orders

USP Provides Price Quotes on Request

Before placing any orders, you may request an official price quote from USP.

Call +1-301-881-0666 or 800-227-8772 or email , specifying the items for which you want to get a quote. Prices on an official quote provided by USP are good through the date specified on the quote.

USP strongly recommends that you obtain a price quote if you intend to pay by wire transfer. When ordering controlled substances, you must get a price quote from USP as it is required for necessary official paperwork and permits.

When you order based on a USP price quote, please provide the quote number on all checks, wires, and/or credit card orders. This will improve accuracy and shorten order-processing time.
