Negotiations for a free trade agreement between Thailand and the European Union have brought intellectual property standards for agriculture to the fore, with Brussels proposing alignment under the 1991 International Convention for the Protection of New Varieties of Plants (UPOV 1991).

Adopting the framework could lift domestic crop production costs by up to 1,000 baht per rai and push consumer prices for rice-based products up by 4%, according to projections cited by Aat Pisanwanich, a lecturer at Rangsit University’s Institute of Economics.

As of November 2026, Thailand regulates plant varieties under its Plant Varieties Protection Act of 1999 and has taken no formal stance on accession, even as regional trade partners prepare bilateral pacts scheduled for implementation through 2027.

Seed procurement represents between 10 per cent and 15 per cent of total crop production costs in Thailand, based on operational metrics from the Thai Seed Trade Association. Shifting to international breeder mandates would alter those balance sheets quickly. Production costs for staple paddy rice would increase by 125 to 500 baht per rai, while feed corn costs would rise by 200 to 800 baht per rai. Industrial sugar cane crops face added outlays between 250 and 1,000 baht per rai, and tapioca expenses would jump by 125 to 500 baht per rai.

For food manufacturers, feed millers, and grocery distributors, these upstream increases squeeze operating margins along the retail supply chain. The projected 4 per cent consumer price increase on packaged rice and processed grain products comes as food retailers across Southeast Asia work to contain shelf inflation.
