Mr. Lim Tai Tin, founder of Chee Seng Oil Factory Pte Ltd came to Singapore when he was a teenager. He started out by working in his relative's company, after which, he ventured into various small businesses including selling dough sticks and fried pancakes.

With an initial capital of $20,000, the entrepreneurial Mr. Lim set up "Chee Seng Oil Factory" in 1943 to produce edible coconut oil, as sources of edible oil during the period of Japanese Occupation was scarce. In 1956, he changed the nature of business from coconut oil production to sesame oil production.

Chee Seng was the first among all the sesame oil manufacturers in Singapore to produce sesame oil with machinery. Mr. Lim painstakingly designed and supervised the installation of all the machines needed in the various stages of production himself, placing product qualities in terms of aroma and purity as his top priorities.

In 1971, Mr. Lim Tai Tin split the shares of his company among his 10 sons and a nephew. The company was renamed "Chee Seng Oil Factory Pte Ltd", as it is known today. He passed away in 1985 at the age of 85.

Being the eldest son, Mr. Lim Bong Hee began helping out in the factory when he was still a student. Now, he led his brothers to bring the business to greater heights. Under his leadership, the company moved towards automation in production and packaging, and increased domestic as well as export sales.

The other brothers running the business are Oy Hoo, Hwee Cheng, Ah Eng, Kim Cheeh, Chwee Lai, Hui Tian, Hwee Soon and Ching Wat. The other two brothers, Hwee Heang and Hwee Ann each has their own businesses.

Mr. Lim Kay Guan, the eldest son of Mr. Lim Bong Hee, grew with the business and is familiar with the entire process and nature of the business, making him the potential leader of the third generation. Currently, Kay Guan is responsible for the further improvement and automation of the factory.
