Dear Customer:

The current international situation is complex and volatile, and the tariff policy remains unclear, which may have a certain impact on the prices of our products. Under these circumstances, we hope to have a friendly communication with you regarding the order matters.

Given the current uncertainties, if you choose to place an order during this period, we reserve the right to adjust the price based on the actual situation. At the same time, we understand that the market changes may bring you some inconvenience. Therefore, if there is a significant price fluctuation due to changes in the tariff policy before the actual delivery of the order, Merck will negotiate with you and adjust or cancel the order as the situation requires.
