Over the past four years, our company has provided inspection and testing services to more than 280 production and trading enterprises in 22 provinces across China. We have identified over 80 types of products, covering fireworks and firecrackers, perforating projectiles, aerosol fire extinguishing devices, automotive safety devices such as airbags; and chemical products in various fields including coatings, refrigerants, phosphoric acid, sulfur, and aerosols. Our company has issued more than 800 dangerous characteristic classification and identification reports for enterprises and compiled over 1000 chemical safety data sheets and safety labels. At the same time, we have provided production enterprises with public interest technical support on the physicochemical parameters, combustion and explosion performance, toxicity, and emergency first aid, fire fighting, leakage emergency response, and operation and storage of chemicals, and provided evaluations and suggestions on their transportation safety; we have also provided strong technical support for ensuring the transportation safety of freight companies. In 2022-2023, our company provided physicochemical parameter testing services for 598 batches of more than 20 types of pesticides, including acetochlor, flumetsulam, glyphosate, flufenoxuron, and pyrimethanil, for two Brazilian companies importing pesticides from China, and issued English test reports. The reports issued by our company have received high praise and recognition from foreign importers and regulatory authorities.

In January 2022, immediately following the release of the Chinese version of the International Maritime Dangerous Goods Code (IMDG Code, 40-20 edition), our technical personnel keenly identified 52 errors in the stowage category of UN numbers for dangerous goods. Given that strict adherence to international regulations for stowage is a key technical measure to ensure the safe carriage of dangerous goods by sea, our company submitted a letter to the Ministry of Transport on February 23, 2022, suggesting corrections to certain items in the stowage category of Announcement No. 8 of 2022. The Ministry of Transport fully acknowledged the significant work done by our company and, in an official email dated June 9, 2022, adopted all of our proposed modifications. The relevant content of the Chinese version of the International Maritime Dangerous Goods Code (IMDG Code, 40-20 edition) was promptly corrected and re-released.

Our company attaches great importance to the revision of international regulations and continuously conducts relevant research. In July 2022, our company proposed a draft amendment to modify two chapter numbers in the ninth revised version of the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS).

In December 2023, our company discovered two inconsistencies between certain technical contents of the national standard GB 12268 "List of Dangerous Goods Names" (draft for comments) and the United Nations Recommendations on the Transport of Dangerous Goods, Model Regulations (22nd revised edition) (hereinafter referred to as "Model Regulations (22nd revised edition)"): 11 UN numbers in the national standard GB 12268 "List of Dangerous Goods Names" (draft for comments) have inconsistent UN packaging categories compared to those listed in the Model Regulations (22nd revised edition); 9 UN numbers in the national standard GB 12268 "List of Dangerous Goods Names" (draft for comments) have inconsistent names, descriptions, and English names compared to those listed in the Model Regulations (22nd revised edition). Our company wrote to the National Standardization Technical Committee for Dangerous Chemicals Management and suggested that the personnel involved in the standard revision should re-verify the inconsistencies between the above-mentioned technical contents and the Model Regulations (22nd revised edition), and further revise the national standard GB 12268 "List of Dangerous Goods Names" (draft for comments). Since the Model Regulations (23rd revised edition) was released in August 2023, and the latest version of the Model Regulations includes some new entries and requirements, it is suggested that all technical contents of the national standard GB 12268 "List of Dangerous Goods Names" should be consistent with the 23rd revised edition. The Technical Committee officially replied to our company on January 2, 2024, stating that the standard committee has notified the drafting group to verify and modify the inconsistencies one by one, and thanked our company for its support to the standardization work of dangerous chemicals management!

As a founding member of the Chemical Supply Chain Expert Committee of the China Standardization Collaborative Innovation Platform, a member of the Chemicals Branch of the China Entry-Exit Inspection and Quarantine Association, and a vice-chairman unit of the Guangxi Emergency Management Association, our company participated in the research and drafting of the national mandatory standard "Specifications for Classification and Labeling of Chemicals Part 1: Explosives for Civilian Use" (Project No.: 20190069-Q-339) and in the revision of GB 12268, the national mandatory standard for hazardous materials testing and identification, for the list of dangerous goods.
