Notice on Product Price Adjustment

To our esteemed customers:

Hello! Sincerely thank you for your long-term trust and support towards Taiyi. We would like to express our sincere gratitude! Hand in hand progress and mutual benefit have always been the philosophy that our company adheres to.

Due to the continuous increase in upstream raw material prices and labor costs, our company's costs have significantly increased, and the original prices are no longer able to meet the supply demand. In order to better serve your company and ensure continuous and stable product quality and high-quality service, after careful consideration, the company has decided to:

Starting from December 1, 2025, the unit price of the company's products will be increased by 10% -20%;

2. Please communicate and coordinate with our sales staff in a timely manner regarding the adjusted unit price, as well as any changes in the price, quantity, and delivery time of outstanding orders.

Please understand and support our partners to jointly maintain the development of the industry! At the same time, our company will continue to repay the trust and support of our partners with high-quality products and efficient services.

This letter is to inform you that congratulations to Shangqi!
