From October 2026 the Department of Internal Trade tracks 17 sensitive items daily, including diesel, plastic pellets, steel bars and sheets, cooking oil, sugar, animal feed, fertiliser, eggs, chicken, pork and fresh milk. Six more items are checked twice a week and 196 every 15 days. If you buy or sell these inputs, expect prices to move quickly and watch your supplier costs. Anyone caught hoarding or manipulating prices faces up to 7 years in prison or a fine of up to 140,000 baht. Eggs are short by about 2 million a day in Prachinburi after floods, and exporters have been asked to slow shipments. Diesel accounts for about 40% of transport costs, so review delivery and freight pricing.
