Market
Dried longan (dehydrated longan aril, sometimes traded as whole-in-shell or as peeled/pitted flesh) is a shelf-stable processed fruit traded primarily within East and Southeast Asia, with China a key destination market. Raw longan production is concentrated in China, Thailand, and Vietnam; Thailand in particular has a large drying industry that converts seasonal fresh supply into exportable product. Trade dynamics are shaped by food-safety and SPS requirements—especially sulfur dioxide residue controls for longan exports—and by demand linked to traditional culinary uses, gifting, and ingredient applications. Because the product is dried, shipment can occur year-round, but availability and pricing can still track seasonal harvest peaks and weather impacts in major origins.
Market GrowthNot Mentioned
Major Producing Countries- 중국Major longan producer and a key demand center for longan-based products (including processed forms).
- 태국Major longan producer with substantial drying/processing capacity; seasonal peaks drive processing throughput.
- 베트남Large longan-producing country in Southeast Asia with growing cross-border trade focus toward China.
Major Exporting Countries- 태국Key supplier of longan products to China; trade can be sensitive to SPS and residue protocols.
- 베트남Important regional supplier of longan products into China and nearby Asian markets.
Major Importing Countries- 중국Primary destination market in the region for longan imports and longan-based products, shaping SPS expectations and buyer specs.
Supply Calendar- Thailand:Jun, Jul, AugIn-season fresh longan supply typically starts in June and peaks in July–August; off-season production exists, and drying converts seasonal supply into a storable, tradable product.
Risks
Food Safety HighSulfur dioxide (sulfite) residue compliance is a critical trade gate for longan exports, with destination-market SPS scrutiny capable of delaying or disrupting shipments. Thailand has treated excess sulfur dioxide residues in longan exports as a serious issue in discussions with China’s customs authority (GACC), including protocol-level expectations and testing basis.Apply validated sulfiting controls where used, implement routine residue testing aligned to destination protocols (including specified sample basis), maintain end-to-end traceability, and ensure additive use is consistent with Codex GSFA and importing-country limits.
Market Concentration MediumRegional trade dependence on China as a dominant destination market increases exposure to policy changes, inspection intensity, and demand shocks affecting prices and offtake for exporting origins.Develop alternative channels (regional retail, ingredient buyers, diversified export destinations) and negotiate flexible specs that can be met across multiple markets.
Quality Degradation MediumInadequate drying, moisture uptake in transit, or poor storage can lead to mold growth and product rejection, especially for higher-grade retail and gifting segments where appearance and cleanliness are critical.Control final moisture through validated drying endpoints, use moisture-barrier packaging, monitor humidity across warehousing, and adopt robust foreign-matter and defect sorting plus COA-based release.
Climate MediumSeasonal fresh longan output (the processing feedstock) is sensitive to weather variability (rainfall patterns, drought stress, and temperature anomalies), which can affect fruit size/quality and the volume available for drying plants.Maintain multi-origin procurement options within the region, use forward planning for peak-season intake, and monitor seasonal production outlooks from horticultural and national sources.
Sustainability- Energy use and emissions from thermal drying (hot-air, oven, or fuel-fired systems) can be a material footprint driver for processed dried longan
- Packaging footprint (plastic moisture-barrier materials) is a recurring sustainability consideration in dried-fruit trade
Labor & Social- Seasonal orchard labor and processing-plant working conditions (wages, hours, heat exposure near dryers) are relevant due-diligence topics for buyers sourcing from smallholder-based supply regions
FAQ
Why is sulfur dioxide (sulfite) compliance a major issue for dried longan trade?Sulfites may be used in dried-fruit processing to manage browning and shelf life, but residue limits are tightly regulated and can be enforced through SPS inspections. For longan exports, Thailand has discussed sulfur dioxide residue concerns and protocol testing expectations with China’s customs authority (GACC), showing that non-compliance can quickly disrupt trade.
Which countries are the main production bases for longan that feed dried-longan supply?Global longan production is concentrated in China, Thailand, and Vietnam, and Thailand is notable for converting seasonal fresh supply into dried product through a large drying/processing sector.
What is the most common quality risk during storage and shipping of dried longan?Moisture uptake is a key risk: if dried longan absorbs humidity, texture and color can deteriorate and mold risk increases. This is why moisture-barrier packaging and dry storage conditions are central parts of buyer specifications and supply-chain handling.
