Its stated mission is to "create fine projects and achieve customer success," and it markets itself as a pioneer among China's overseas engineering contractors.

Wuhuan Engineering Co., Ltd. traces its origins to the Fourth Design Institute of the Ministry of Chemical Industry, founded in 1958. Over the following decades it developed into one of China's leading chemical engineering design organizations, building expertise in ammonia and ammonia processing, phosphorus chemicals and coal chemicals. The institute was later restructured into a modern engineering company and became a wholly owned subsidiary of the state-owned China National Chemical Engineering Group Corporation (CNCEC). In its modern form, Wuhuan has positioned itself as an international engineering company integrating technology R&D, engineering science and technology, engineering services and industrial operations. It holds a comprehensive Grade A engineering design qualification and has been designated a national high-tech enterprise, hosting a national-level enterprise technology center and a national energy center for low-rank coal comprehensive utilization. The company reports having completed more than 3,000 medium and large design projects and over 300 EPC projects, including more than 200 overseas projects, and having won more than 320 national and provincial/ministerial awards. Wuhuan's project portfolio spans China and overseas markets. Domestic reference projects cited by the company include the Hubei Yunhua'an 400,000 t/y synthetic ammonia project, the Shandong Hualu Hengsheng 1 million t/y urea plant, the China Coal Tuke phase-one 500,000 t/y synthetic ammonia and 800,000 t/y urea project, the Shenhua Baotou 600,000 t/y coal-to-olefins project, the Hami Guanghui 400,000 t/y coal-gas-to-ethylene glycol project, the Shenhua Ningmei polyoxymethylene project, the Wengfu Dazhou phosphorus chemical project and the Hubei Xingfa phosphoric acid project. Overseas reference projects include the Vietnam Ca Mau fertilizer project, the Indonesia PKG ammonia-urea project, the Egypt NCIC phosphate fertilizer project, the Indonesia PJA project and the Tunisia 360,000 t/y phosphoric acid project. In recent years the company has continued to expand its domestic and international footprint. It has signed cooperation agreements with partners such as China Pingmei Shenma Group and Tianjin Cement Industry Design and Research Institute, deepened cooperation with Yichang city on chemical industry development, and relocated its Indonesia branch office to the IFC in Jakarta. It has also advanced green and circular-economy projects, including a million-tonne-scale phosphogypsum-to-sulfuric-acid co-production project. Wuhuan states that it has been repeatedly ranked among China's top 80 contractors by ENR/China Construction Times and placed 36th in the China Survey and Design Association's 2020 ranking by completed EPC contract value.
