The specific contents of chemical management：

Procurement Stage

The procurement of hazardous chemicals is centrally managed by the Materials Supply Department. The Company strictly reviews the qualifications of suppliers and carriers. Safety Data Sheets and safety labels must be provided during procurement, and hazardous chemicals that have not been inspected or fail to meet applicable requirements are not allowed to be stored or used.

Handling and Transportation Stage

The transportation, loading, and unloading of hazardous chemicals are carried out by qualified entities and personnel. The Company strictly implements safe operating procedures, strengthens on-site vehicle monitoring, and enforces safety requirements for transport vehicles and loading and unloading areas to ensure safety throughout the entire loading, unloading, and transportation process.

Storage Stage

The storage and use of hazardous chemicals strictly comply with applicable national laws, regulations, and standards. The Company implements classified storage, provides necessary safety facilities for fire prevention, explosion prevention, poisoning prevention, and leakage prevention, and ensures that safety signs and protective measures are properly in place, so as to keep the storage and use processes safe and controllable.

Usage Stage

The Company conducts comprehensive identification and classification management of chemicals involved in its production and operation activities, and dynamically updates its list of hazardous chemicals and related characteristic information. It centrally manages information on the physicochemical properties, health risks, protection requirements, and emergency response measures of chemicals, while strictly regulating requirements for requisition, use, and on-site operations.

Disposal Stage

Hazardous chemical waste and scrapped materials are collected by category and disposed of in a standardized manner in accordance with applicable requirements. The disposal of scrapped materials strictly follows the required approval procedures. Arbitrary disposal, discarding, or unauthorized handling is strictly prohibited to prevent environmental pollution and safety risks.

In strict accordance with applicable laws, regulations, and catalog requirements for hazardous chemicals, the Company identifies, classifies, and manages various chemicals involved in its production and operation activities by category and risk level. It dynamically updates its list of hazardous chemicals and related characteristic information to ensure that chemicals are safely controlled throughout use, storage, and disposal. As of the end of 2025, the Company had achieved 100% coverage of hazardous chemical risk identification and safety management.

At the same time, the Company continued to advance the reduction and substitution of chemicals by gradually replacing certain traditional chemicals with reagents that present lower risks and better environmental performance. These efforts continuously reduce safety and environmental risks during operations and promote the upgrading of chemicals management toward a safer and more environmentally friendly approach.
