Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.
