Dear Valued Customers,

Due to recent geopolitical frictions and turbulent international situations, domestic supply chains have been affected, leading to rising production material prices, unstable supply, and longer delivery times.

Coupled with the continuous depreciation of the USD against the RMB and domestic inflation, we have to raise prices of some products under the current market conditions.

Please Note: All previous quotes are invalid. Starting today, the selling price must be recalculated based on the day's material price before ordering. Material prices may continue to rise in the near future, supply instability will persist, and prices will be hard to fall back due to inflation.

1. For customers negotiating orders, confirm orders as soon as possible to avoid higher unit prices and delayed delivery.

2. If conditions permit, appropriately increase inventory or order quantity to maintain enough safe stock against potential price hikes.

Our team solemnly commits: we will try our best to avoid or minimize price increases, and bear all affordable cost pressures ourselves. We will only raise prices when we cannot absorb the costs, and finally, please make corresponding adjustments and response measures based on the current situation as soon as possible.

Thank you for your long-term support to the VIKSTARS team. We will continue to provide quality products and services, and appreciate your understanding and cooperation.
