Thailand Palm Oil Industry on Alert: B50 Mandate Shock and Stricter Diesel Import Rules

For Thailand, the most direct lever highlighted in the sources is not a domestic jump to B50, but supply management. Energynews.pro reports Thailand introduced a restriction on crude palm oil exports that was published in the Royal Gazette on April 5, 2026 and took effect April 7, 2026. The stated effect is straightforward: it reduces the volume available to global markets at a time when regional biodiesel demand is rising. In practice, that aligns with the broader regional shift described in multiple sources, where more crude palm oil is diverted into domestic fuel consumption, potentially at the expense of export-available volumes.

B50 and Trade Controls Tighten the Regional Palm Oil Balance

Indonesia’s B50 rollout is a large demand anchor in the regional equation. IndexBox’s Asia biodiesel report states Indonesia accounts for 61% of regional consumption at 8.1 million tons and 55% of production at 8.2 million tons, with its mandate-driven demand dominating the market. Palm Oil Magazine adds the scale of feedstock needs implied by B50: producing 19.5–20 million kiloliters of biodiesel under B50 would require about 17.5–18 million metric tons of CPO, versus 13.9–14 million metric tons under B40. That additional 3–4 million metric tons of CPO demand is estimated to reduce Indonesia’s CPO exports by 2–3 million metric tons annually, tightening availability for global buyers and neighboring markets alike.

Trade data in the IndexBox report illustrates why regional policy shifts can quickly create price and product dislocations. It reports 2024 average export prices for biodiesel at $1,071 per ton versus import prices at $551 per ton, indicating a stark gap that reflects different specifications, feedstock costs, and trade flows. It also notes that China, Malaysia, and South Korea collectively account for 83% of Asia’s biodiesel export value, underscoring how supply and demand shocks can ripple across the region through trade channels. For stakeholders focused on the Thailand palm oil industry, these numbers matter because changes in export availability and blending mandates can influence where biodiesel and its feedstocks are most competitively priced and most tightly supplied.

Thailand’s strategic question is not only about copying high blends, but about feasibility and risk. Krungsri Research argues that if Thailand were to follow high-blend approaches like B50, it would face challenges and high risks tied to structural constraints, including insufficient upstream feedstock supply, emission-standard enforcement, growing consumer preference for electric vehicles, and the risk of engine-system damage from high-blend fuels. As an alternative direction, it suggests developing advanced biorefineries to produce drop-in fuels such as renewable diesel (HVO) or sustainable aviation fuel (SAF), targeting premium export markets and global aviation. At the regional market level, IndexBox’s outlook to 2035 emphasizes that growth is heavily contingent on blending-mandate stability and that the supply-side shift is likely to involve advanced feedstocks such as used cooking oil (UCO), palm oil mill effluent (POME), and non-edible oils.
