Office of the Cane and Sugar Board (OCSB)
Office of the Cane and Sugar Board (OCSB) is the structural Thai sugar-industry regulator under the Ministry of Industry. Administers the Cane and Sugar Act framework: sets annual cane purchase prices, allocates mill quotas across the ~58 Thai sugar mills, oversees the 70:30 mill-grower revenue-share rule, and coordinates ethanol-blending mandates with Department of Energy Business. Coordinates with WTO sugar-subsidy enforcement and US-Brazil trade-policy disputes affecting Thai sugar export.

Key regulatory mandates
Cane Pricing
Annual Cane Price-Pledging
OCSB sets the annual base cane purchase price (THB/tonne) under a formula linking global raw-sugar ICE prices to domestic field-input costs. FY2023 base cane price was $31.9/tonne; mills operate a 70:30 revenue-sharing mechanism with growers.
Mill Quotas
58-Mill Quota Allocation
Allocates production quotas (A-quota domestic, B-quota industry, C-quota export) across the ~58 registered Thai sugar mills. Quota caps shape inter-mill competitive dynamics and constrain capacity expansion without OCSB approval.
Ethanol Link
Ethanol Blending Coordination
Coordinates with Department of Energy Business (DEDE) on mandated ethanol withdrawal from sugar mills. E10 and E20 ethanol mandate volumes are calibrated against molasses availability from cane crushing seasons, affecting sugar-ethanol price parity.

Watchpoints 2025-2026
WTO
Sugar Subsidy Dispute
Brazil and Australia have challenged Thai C-quota export subsidies at WTO DSB. If adverse rulings are upheld, OCSB will need to restructure the revenue-sharing mechanism and direct grower-subsidy programme, potentially raising mill operating costs.
Climate
Drought Yield Impact
Sugarcane yield is highly sensitive to rainfall during growing season. 2024-2025 El Nino drought conditions risk reducing cane crush to 80-85M tonnes, tightening domestic quota and pressuring mill capacity-utilisation economics.
Biofuel
Ethanol Mandate Expansion
If DEDE expands E20 mandate, OCSB must coordinate molasses withdrawal volumes across mills. Structural tension between maximising sugar export revenue (higher global prices) and meeting ethanol-blending mandates is a policy pressure point.
