OSIM International Ltd (傲胜国际企业), was originally established in Singapore in 1980 by Ron Sim, as an electrical and household appliance company under the name of R Sim Trading. With a small start-up capital, the company was mainly involved with the marketing of household products such as knives, knife sharpeners and mobile clothes drying rods. In 1989, the company registered the name Health Check and Care, and saw a shift in focus to healthy lifestyle products. The period following this saw tremendous growth for the company, and it developed outlets including Malaysia and Indonesia.
In 1993, the company officially launched the OSIM brand name and its distribution network expanded to 60 point-of-sale outlets in Asia. In 2002, OSIM opened its global business headquarters in Singapore at 65 Ubi Avenue 1. The Business Headquarters Status (BHQ) was awarded to OSIM by The Economic Development Board. In 1993, the company opened its first concept shop in Shanghai, in the People’s Republic of China.
In October 2005, OSIM made a strategic acquisition of US Nationwide specialty retailer Brookstone. OSIM is a combination of the surname of its founder, Sim, and 'O' that stands for the globe.
