Dear Valued Customers,

Greetings!

First and foremost, we would like to express our sincere gratitude for the continued trust and support you have extended to our company. It is through the concerted efforts of partners like you that we have been able to achieve steady growth in a highly competitive market.

Recently, due to multiple factors including the international political and economic landscape as well as fluctuations in global supply chains, the supply-demand dynamics in the market have shifted significantly. The prices of the primary raw materials used in our products—specifically non-ferrous metals such as **aluminum and copper**—have experienced sustained and substantial increases, with both the magnitude and duration far exceeding normal fluctuations. Concurrently, costs associated with packaging materials and logistics transportation have also risen. This has led to a sharp surge in our production and operational costs, making it increasingly difficult to sustain our original pricing structure.

As a company committed to integrity and long-term, mutually beneficial partnerships with our customers, we always prioritize product quality and customer service above all else. We fully understand the importance of price stability for your business operations. Therefore, over the past period, we have internally implemented a series of measures to optimize production processes, enhance efficiency, and explore internal cost-saving potentials. Our goal was to absorb as much of the cost pressure as possible through internal efforts to maintain price stability and navigate these challenges alongside you.

However, faced with the unprecedented escalation in raw material costs, internal optimization alone is no longer sufficient to offset the immense impact on our cost base. In order to continue providing you with products that meet our consistently high-quality standards, along with reliable technical support and service—and to ensure the long-term stability and health of our partnership—we have, after careful consideration by management and a thorough review of market conditions, made the difficult decision to implement a moderate price adjustment for selected products.

The details of the adjustment are as follows:

1. **Product Scope**: This price adjustment primarily applies to product lines where aluminum and copper are the main raw materials. This includes, but is not limited to, flow meters, pumps, nozzles, various fittings, filter housings, hose couplings, etc. Prices for products less affected by the raw material cost increases will remain unchanged for now.
2. **Adjustment Magnitude**: The adjustment percentage will vary depending on the proportion of raw material costs in each specific product model. Contact our sales for the latest price list of main hot sales products before you order.
3. **Effective Date**: The new price structure will take effect from March 16th, 2026.
* Orders placed before this date, for which payment has been completed or a deposit has been paid as per the contract, will still be honored at the original price.
* New orders placed after this date will be invoiced according to the adjusted prices.
* For orders already confirmed but not yet delivered, we will proactively communicate with you to find a mutually agreeable solution.

We sincerely apologize for any inconvenience this price adjustment may cause and earnestly seek your understanding and support. We solemnly assure you that this necessary measure is taken to cope with the extraordinary market environment and is by no means a short-term action. We remain committed to strictly controlling product quality, continuously optimizing our production processes, and striving to enhance product value through technological innovation, ultimately providing you with more competitive solutions.

We firmly believe that through open communication and mutual understanding, we can successfully navigate the current market challenges together and achieve even greater long-term cooperation and development. Thank you once again for your continued trust and understanding!

Should you have any questions regarding this price adjustment or wish to discuss it further, please do not hesitate to contact your designated sales manager or our sales department.

We wish you prosperity and continued success.
