Tantech Holdings Ltd. TANH

What this company does

We develop, manufacture and trade bamboo-based charcoal products for household purification, agricultural and cleaning uses. 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. 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. 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. We oversee a national sales network that has a presence in 19 cities throughout China for our charcoal products. We are headquartered in the bamboo-rich southwest of Zhejiang Province, in the city of Lishui. We currently own five patents and eighteen trademarks in China covering our bamboo charcoal production.
