JC Chemical Co., Ltd. is a South Korea-based renewable energy and oleochemicals manufacturing company primarily engaged in the production and distribution of eco-friendly biofuels and specialty chemical products. Founded in 2006 and headquartered in Ulsan, South Korea, the company operates across two principal business divisions: Biofuel and Oleochemicals. Its core product portfolio comprises biodiesel (BD100, BD20, and BD5) manufactured from vegetable oils, used cooking oil, and animal fats for mandatory automotive fuel blending; bio heavy oil utilized as a low-carbon substitute for conventional heavy fuel oil in thermal power generation facilities; refined glycerin produced as a high-purity oleochemical byproduct for use in cosmetics, pharmaceuticals, food additives, and industrial surfactants; and fatty acids, pitch, and related oleochemical derivatives used in specialized industrial chemical applications. Through its subsidiaries in Indonesia, the company manages oil palm plantations and crude palm oil extraction facilities, securing an integrated upstream supply chain for raw feedstocks. JC Chemical supplies its products primarily to major domestic petroleum refiners, state-owned electricity generation utilities, and industrial chemical enterprises across South Korea and regional export markets. In recent operational developments, JC Chemical has expanded into next-generation biofuels, focusing on Sustainable Aviation Fuel (SAF) feedstocks and bio-marine bunker fuels to meet stringent international aviation mandates and maritime decarbonization standards. The company has enhanced its waste feedstock refining infrastructure at its Ulsan plant to increase the processing ratio of circular waste oils, secured International Sustainability and Carbon Certification (ISCC EU / ISCC PLUS) across its supply chain, and entered into strategic supply agreements with leading domestic energy refiners to advance commercial distribution of low-carbon transportation fuels.
