The Agriculture Ministry enforces strict integrated quality control of durians in the eastern region, moving forward to prevent"immature durians"to build consumer confidence and maintain the Thai durian image.
Ms. Anchalee Suwajittanon, Director-General of the Department of Agricultural Extension, said the department, as secretary of the Fruit Development and Management Committee, is responding to directives from Ms. Piyaratch Tiyapairat, Deputy Minister of Agriculture and Cooperatives. They are integrating all sectors to intensively control durian quality in the eastern region to block "immature durians" and substandard products from entering the market, boosting consumer confidence and preserving the reputation of Thai durians both domestically and for export markets.
Currently, the Department of Agricultural Extension, together with related agencies, is continuously implementing quality control measures for durians. These include establishing checkpoints, randomly testing dry weight percentages, pre-harvest inspections, and organizing orchards and packing houses in the three main producing provinces in the eastern region: Chanthaburi, Rayong, and Trat. The “Pre-Harvest Inspection” service points aim to organize orchards and ensure durian quality confidence in the eastern region. From 1 March to 7 May 2026, a total of 53 points operated across the three key provinces, providing services to 15,136 samples from 11,938 farmers: 6,534 samples in Chanthaburi, 5,024 in Trat, and 3,578 in Rayong.
In Rayong Province, integration involved local administration, community leaders, police officers, farmer representatives, and agricultural agencies establishing four checkpoints: Kong Din Subdistrict, Sala Khiao, Ban Nong Kui, and Phang Rad. They inspected a cumulative total of 645 durian transport vehicles, randomly testing dry weight percentage for every vehicle. Only 2 samples failed the standard, prompting retesting and educating harvesters and traders to adhere to the principle “Do not harvest or sell immature durians” to sustainably maintain Thai durian standards. In Chanthaburi, 633 durian trucks were inspected at checkpoints in Khlung, Nayaiam, Makham, and Tha Mai districts.
In Nayaiam, Makham, and Tha Mai districts, 57 samples were randomly tested for dry weight percentage; 51 met standards while 6 failed. For trucks potentially at risk of not meeting standards, officials coordinated with destination packing houses for strict product sorting. The Agricultural Research and Development Office Region 6 will inspect and enforce compliance with TAS 9070-2566 standards. Additionally, Chanthaburi Provincial Agricultural Office and district offices coordinate to monitor packing houses to prevent substandard durians entering the market. They found 43 substandard fruits weighing 119 kilograms in Nayaiam district and 208 fruits weighing 496 kilograms in Mueang Chanthaburi district. Officials marked and segregated these to prevent them from reaching the market, following provincial fruit quality control measures.
In Trat Province, a special task force to prevent and resolve substandard durian issues established four checkpoints covering Khao Saming, Bo Rai, and Mueang Trat districts. A total of 1,687 durian trucks passed these checkpoints. At the key checkpoint in Ban Tha Jod, Khao Saming district, 1,473 trucks presented complete dry weight percentage inspection certificates. Trucks without certificates underwent external durian inspection and additional random dry weight tests, with all sampled Monthong durians passing the standards.
Regarding the harvesting situation in the eastern region as of 7 May 2026, a total of 424,269 tons of durians have been harvested, accounting for 42.51% of the total crop. Trat has harvested 84,849 tons (59.74%), Rayong 83,129 tons (39.56%), and Chanthaburi 256,291 tons (39.68%). The peak market supply is expected in May.The Ministry of Agriculture and Cooperativescontinues to enforce Thai fruit quality control to build consumer confidence, preserve the Thai durian's global image, and ensure stable and sustainable income for Thai farmers.
