USP currently offers more than 3,500 Reference Standards—highly characterized specimens of drug substances, excipients, food ingredients, impurities, degradation products, dietary supplements, compendial reagents and performance calibrators. USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories.

USP recognizes the continuing increase in industry cost. This coming year, USP expects to see our own costs increase due to our continued investment in global public health. However, we will not take a general price increase at this time. USP reserves the right to make adjustments on a case by case basis, should conditions change. We thank you for your continued support of USP efforts to help ensure the quality of medicines, foods and dietary supplements and provide industry with the products and services you need, at a fair value.
