Crude cassia oil prices in Vietnam have risen by 15% compared with the same period last year, as a difficult growing season and a shrinking rural workforce put pressure on supply at origin.

The increase matters well beyond Vietnam’s borders. The country is one of the world’s largest producers of cassia oil – a key natural source of cinnamaldehyde for the flavour and fragrance industry – and price movements at origin tend to ripple quickly through the global supply chain.

A Difficult Season in the Growing Regions

This year’s challenges began with the weather. Vietnam saw an unusually long summer in 2026, followed by an autumn that ended earlier than usual. The shift disrupted the natural growth cycle of cassia trees and left yields lower across the main growing regions.

The effects carried through to harvest time. Harvesting got under way later than usual, output came in below normal levels, and unfavourable conditions made the work itself harder. By the end of the season, distillers had received less raw material than in a typical year, and supply at origin had tightened as a result.

Alongside the weather, a longer-term trend is also at play. Many rural workers continue to leave for jobs in cities and industrial zones, and the cassia sector is feeling the impact.

Harvesting and distillation still rely heavily on manual labour, especially in mountainous areas where much of the work cannot easily be mechanised. With fewer people available, wages have gone up – and so has the cost of producing every kilogram of oil.

How It Affects Purchasers

Together, tighter raw material supply and higher production costs have pushed crude cassia oil prices up at origin. For buyers, the most immediate effects are likely to be longer lead times and less room to adjust order volumes at short notice.

Prices are expected to stay firm for as long as these conditions persist. Rather than relying on last-minute purchases, buyers would be well advised to plan their volumes early and confirm delivery schedules with suppliers in good time.
