Given that natural resources are not unlimited, we asked our partners to start afforestation for the supply of raw materials for Tekho to manufacture "pure natural borneol" to meet the needs of the biochemical industry. So far, Tekho has become the only manufacturer that can supply a series of borneol products in Taiwan.

In view of the insufficient use of Zhonghe's plant and difficulty in meeting the needs of future development, we invested a large amount of money to establish "Taiwan Fine Chemical Co., Ltd." at No. 6-11 Nanshanding, Yangmei Town, Taoyuan County, Taiwan, about 4.1 acres of land, specializing in the production of monomer fragrances.

The launch of Camphoric Acid developed international market successfully so that our company is deeply valued by the world's major pharmaceutical companies in the market of the raw materials of Western medicine's splitting agent.

Renewed broneol production equipment, started to make natural refined broneol and then imported synthetic camphor powder from Germany to produce synthetic broneol in order to increase items for sales.

Due to the loss resulted from unsuccessful operation, Taiwan Camphor Plant run by National-owned Monopoly Bureau ended in 1967. The Authority permitted private investing in camphor processing. The father and son, Mr. Shih-Ho Teng and Mr. Mao-Nan Teng, bid all the equipment in 1967 and then　Mr. Mao-Nan Teng spent four-month of removing, one-year assembling & installing to finish fractional distillation equipment. Besides, engaging expert to design sublimation equipment and then ready for production in 1968. To meet the demand of extending, we merged Chi-Mei company’s plant and renamed our company 「Taiwan Tekho Camphor Co., Ltd.」on 4th July, it is the first private camphor plant in Taiwan, Mr. Shih-Ho Teng held the post of president, Mr. Mao-Nan Teng held the post of general manager. We extended from only broneol to a variety of product lines like natural camphor powder, camphor flake, white camphor oil, Rhodinol natural Ex-citronell for exporting worldwide to Europe, the USA and Japan.

Our founder, Mr. Sih Ho Teng set up Tekho Chemical Industry Plant at Chung Ho City, Taipei County, purchased “natural camphor powder” from 「Taiwan Camphor plant」to make “natural borneol” for traditional Chinese medicine, also supply for pharmaceutical and fragrance use, like prickly heat powder, pain relief patch, Ryukakusan…etc., and exported to Vietnam, as well.
