What Tantech Holdings Ltd does.

We develop, manufacture and trade bamboo-based charcoal products for household purification, agricultural and cleaning uses. We have grown over the past decade to become a pioneer in charcoal products made from carbonized bamboo. Historically we have been a specialized manufacturer of bamboo charcoal-based products with primary business focus on low emission BBQ charcoal and other charcoal consumer products. After completing a series of reorganizations and business strategic changes, through our operating subsidiaries, today we primarily engage in development, production and distribution of various charcoal products, as well as trading bamboo charcoal products. Our products include purification and deodorization products, and household cleaning products designed for China domestic market. We also have investments in mining exploration and forest assets that can be used for Chinese herbal medicine and flower cultivations. In July 2017, we acquired 70% of the equity of Suzhou E Motors Co, which was later renamed as Shangchi Automobile, a vehicle manufacturer based in Zhangjiagang City, Jiangsu Province. Shangchi Automobile had developed a variety of electric vehicles and specialty vehicles, such as driverless street sweepers. In May 2025, we divested all of the equity we held in the subsidiaries conducting electric vehicle business to a third party and discontinued the electric vehicle segment operations. In 2022, we expanded into biodegradable packaging business and commercial factoring service business. In 2023, we merged our biodegradable packaging business into our consumer products segment. In 2025, we discontinued offering commercial factoring services to customers with accounts receivable. We launched our operations in North America in 2022 and entered the construction materials industry through the establishment of U.S. subsidiaries based in California in 2024.
