The Intellectual Property Department revealed the list of Thai GI coffees with outstanding sales in 2025, generating nearly 1.5 billion baht in total market value.
Mrs. Ornmon Sapthaweetham, Director-General of the Intellectual Property Department, disclosed that Thailand currently has 11 registered Geographical Indications (GI) for coffee products from eight provinces: Doi Tung coffee (Chiang Rai), Doi Chang coffee (Chiang Rai), Thepsadet coffee (Chiang Mai), Doi Suan Ya Luang coffee (Nan), Doi Mu So coffee (Tak), Wang Nam Khiao and Dong Ma Fai coffee (Nakhon Ratchasima), Ranong coffee, Khao Thalu coffee and Tham Singh coffee (Chumphon), and Krabi coffee. In 2025, these 11 products achieved combined sales exceeding 1.497 billion baht.
Among Thai GI coffees, the top five by market value, totaling 1.318 billion baht in sales, include: first, Doi Suan Ya Luang Nan coffee with sales over 526 million baht from a production volume exceeding 2,257 tons. Its average retail price is 500 baht per kilogram, an increase of over 1.78 times from the pre-GI price of 280 baht per kilogram.
Second is Ranong coffee with sales exceeding 262 million baht from over 947 tons produced. Its current average retail price is 600 baht per kilogram, up more than 7.5 times from the previous 80 baht per kilogram before GI registration. Third is Khao Thalu coffee from Chumphon province, generating sales over 234 million baht from production exceeding 390 tons, with an average retail price of 450 baht per kilogram, increasing 1.95 times from the pre-GI price of 230 baht per kilogram.
Fourth is Doi Chang coffee from Chiang Rai, with sales over 160 million baht from 75 tons produced. It has an average retail price of 1,600 baht per kilogram, rising 1.43 times from the former 1,120 baht per kilogram before GI registration. This coffee is also registered as a GI product in the European Union and Japan. Fifth is Tham Singh coffee from Chumphon, achieving sales over 136 million baht from more than 120 tons produced, with an average retail price of 850 baht per kilogram, up 1.7 times from the previous 500 baht per kilogram before GI registration.
"The strength of Thai GI coffee lies in its unique aroma and flavor, which clearly reflect the identity of its production area—including geography, climate, cultivation methods, and the longstanding wisdom of local farmers. When combined with standardized processing, this preserves the quality and distinctiveness of Thai GI coffee from various sources. This elevates Thai coffee from an agricultural product to a premium good, creating economic value, stable income, and sustainably improving the quality of life for communities in many regions," she said.
