Dear Valued Global Customers and Partners,

As the Chinese New Year approaches, bringing with it new beginnings and fresh energy, all of us at Tongda extend our warmest festive greetings to you and your team. We sincerely thank you for your trust, support, and collaboration over the past year.

In accordance with the Chinese New Year holiday schedule and our company’s operational arrangements, our office will be closed for the Spring Festival holiday from February 11 to February 24, 2026, for a total of 14 days. Normal business operations will resume fully on February 25, 2026, with all departments resuming their regular activities.

During this period, order processing, production scheduling, logistics shipments, and regular customer service consultations will be suspended. For any urgent matters, please email us at firefly@tongdatek.com. We recommend planning your procurement and logistics needs in advance to ensure a smooth transition after the holiday.

Looking back on 2025, thanks to your support, our company has achieved steady growth in the field of high-end manufacturing equipment. Our products, including X-ray diffractometers and single-crystal diffractometers, have gained recognition in advanced manufacturing supply chains across multiple countries and regions, thanks to their outstanding stability and precision. Our continued commitment to technological innovation was further strengthened with the launch of an intelligent inspection production line in the third quarter, enhancing both our production capacity and quality control standards—achievements made possible through your ongoing trust and partnership.

Over the past year, we have worked together to navigate the fluctuations and challenges in the global supply chain while also seizing new development opportunities amid changes. Your trust and support have been the fundamental driving force behind our continuous innovation and steady progress. In 2026, we look forward to deepening our collaboration with you further, not only maintaining efficient synergy in order exchanges but also engaging in more strategically significant cooperation in areas such as technological exchange, market expansion, and sustainable development.

As we bid farewell to the old year and welcome the new, Dandong Tongda Technology sincerely wishes you a joyful New Year, prosperous business, and a happy family! May we continue to deepen our cooperation in 2026, work together to navigate the opportunities and challenges in the global supply chain, and jointly create a brighter future for high-tech manufacturing.

We look forward to achieving new successes with you in the coming year!

Warm regards,
