 Dear Customers,

As the International Labor Day approaches, all employees of Sunlong Biotech Co., Ltd. would like to extend our sincerest festival greetings to you and express our heartfelt gratitude for your continuous trust and support!

To celebrate the Labor Day, our 2026 Labor Day holiday arrangement is formulated in light of the company’s actual operation as follows:

• Holiday Period: May 1, 2026 – May 5, 2026 (5 days in total). Normal work will resume on May 6, 2026.

• Shipping Arrangement: Shipping services will be suspended from April 28, 2026 (the last three working days before the holiday). After resuming work on May 6, we will arrange shipments in the order of order submission, and orders placed during the holiday will be processed on a priority basis.

• Customer Service & Technical Support: During the holiday, our customer service, technical support and other positions will be offline. For urgent matters, you may contact our corresponding person in charge via the reserved contact information, and we will respond to you as soon as possible.

We sincerely apologize for any shipping delays caused by the holiday! We will repay your support with better products and services after the holiday, and look forward to working hand in hand with you for mutual benefit and win-win cooperation in the new season.

Hereby notify.
