Doi Kham is one of Thailand’s leading food producers, established as part of the royal development initiatives aimed at improving the livelihoods of agricultural communities in northern Thailand. The company’s origins date back to 1972, when the first Royal Factory was established to process agricultural products, while Doi Kham was formally incorporated in 1994. Operating as a socially responsible enterprise, Doi Kham works closely with thousands of local farmers, providing reliable market access and fair prices for their crops while supporting sustainable rural development. Today, the company produces more than 220 products across 23 categories, including fruit juices, tomato products, honey, jams, dried fruits, and other food specialties. It is particularly well known for its tomato-based products and fruit juices made from locally sourced Thai ingredients. Doi Kham operates three production facilities in the provinces of Chiang Mai, Chiang Rai, and Sakon Nakhon, while its products are distributed through an extensive retail network across Thailand. The company is widely regarded as one of the country’s most successful examples of combining agricultural development, social responsibility, and food production, with products recognized for their quality, natural ingredients, and support of local farming communities.
