Hunan Linong Wubeizi Industry Development Co., Ltd. was established on July 2, 2007. It is located in the Industrial Park, Xingye Road, Mayang Miao Autonomous County, Huaihua City, Hunan Province. The company mainly engages in the manufacturing of chemical raw materials and chemical products.
Since its establishment, the company has adhered to the development philosophy of innovation-driven growth and steady progress. Starting from the early stage of gallnut planting base development and primary gallnut production and harvesting, we have continuously overcome key technical bottlenecks. We have independently developed core technologies for gallnut aphid breeding and gallnut fruiting at altitudes below 800 meters, successfully realizing industrial upgrading from raw material cultivation to intensive processing. A complete gallnut industrial chain integrating planting, R&D, production and sales has been established.
Committed to quality as always, the company has gained wide recognition with its superior product quality and strong brand influence. In 2013, Linong brand gallic acid was awarded the title of “Hunan Famous Brand Product”. In 2016, the “Linong” trademark was recognized as a “China Well-Known Trademark” by the State Administration for Industry and Commerce. Its brand value and industry influence continue to rise steadily.
Today, the company has grown into a benchmark full-industry-chain enterprise in China's gallnut industry, equipped with modern production facilities and advanced technologies. It holds 11 authorized invention patents and 1 utility model patent, with more than 30 full-time R&D professionals. In 2024, R&D investment exceeded 2.5 million yuan. The company produces more than 20 types of deep-processed gallnut products, with major annual outputs including 1,500 tons of gallic acid, 800 tons of propyl gallate, and 300 tons of tannic acid. Our products are widely used in medicine, chemical industry, food, electronic chips, aerospace, shipbuilding, military supplies and feed additives. They are sold throughout China and exported to Germany, the United States, Japan, South Korea, India, the United Kingdom and many other countries, establishing a high-quality brand image in the international market.
