Industry PositionPrimary Agricultural Product
Raw Material
Commodity GroupSpices and culinary herbs (dried aromatic leaves)
Scientific NameCitrus hystrix DC.
PerishabilityLow (dried, moisture-sensitive)
Growing Conditions- Grows primarily in wet tropical biomes (tropical to subtropical conditions)
- Perennial shrub or tree habit typical of Citrus species; leaf harvest can be repeated from established trees
Consumption Forms- Whole dried leaves for infusion in soups/curries (removed before serving)
- Cut/shredded dried leaf for faster flavor release
- Powdered form as an ingredient in seasoning blends
Grading Factors- Low foreign matter and physical contamination (stones, stems, insects, extraneous plant material)
- Dryness/moisture control to prevent mould growth during storage and shipment
- Leaf integrity (whole leaves vs excessive breakage) and uniform color (limited browning)
- Aroma strength as a practical indicator of essential oil retention
- Microbiological status appropriate for dried aromatic herbs/spices and destination-market requirements
Market
Dried makrut (kaffir) lime leaves (Citrus hystrix) are a niche, high-aroma culinary herb traded internationally as a dried aromatic leaf within the spices and culinary herbs segment. Supply is concentrated in tropical Asia within the species’ native range, with production typically linked to small orchards and herb processors serving regional cuisine and export-oriented specialty buyers. Because the product is often grouped under broader “spices/dried aromatic herbs” or “dried leaves” customs categories, official global trade statistics are not consistently product-specific. Key market dynamics center on aroma retention (drying method and storage), contamination control (microbiological hazards and mould/mycotoxins), and labeling choices in markets that prefer the term “makrut” over “kaffir”.
Major Producing Countries- 태국Within the species’ documented native distribution; widely used and cultivated in the region.
- 인도네시아Within the species’ documented native distribution across multiple islands; potential origin for dried-leaf supply.
- 베트남Within the species’ documented native distribution; regional culinary use supports production incentives.
- 캄보디아Within the species’ documented native distribution; part of the core Southeast Asian growing zone.
- 말레이시아Within the species’ documented native distribution (Malaya/Borneo); cultivation supports regional herb supply.
Specification
Physical Attributes- Aromatic citrus leaf from makrut lime (Citrus hystrix), typically traded as whole leaves or cut pieces after drying
- Quality in trade commonly judged by intact leaf appearance (low breakage), green-to-olive color (limited browning), and strong citrus aroma
Packaging- Sealed moisture-barrier retail pouches or jars for specialty spice markets
- Bulk foodservice or industrial packs (lined cartons or poly bags) with emphasis on moisture protection during transport and storage
ProcessingLow-moisture product where inadequate drying or humid storage can enable mould growth and elevate mycotoxin riskMay be further processed into smaller cuts or powder for seasoning blends, increasing the importance of foreign-matter control and traceability
Supply Chain
Value Chain- Leaf harvest from Citrus hystrix trees → initial sorting/cleaning → drying (sun drying or mechanical drying) → removal of foreign matter (manual or detectors) → packing into moisture-protective materials → export shipment → repacking/retail or blending as a spice ingredient
Demand Drivers- Global demand linked to Thai and Southeast Asian cuisine adoption in retail, foodservice, and spice blends
- Preference for shelf-stable formats versus fresh leaves in long-distance distribution
Temperature- Not a cold-chain product, but storage and transit should avoid heat exposure that can accelerate aroma loss and avoid conditions that create condensation inside packaging
Shelf Life- Shelf stability depends primarily on staying dry; humidity ingress increases mould/mycotoxin risk and can trigger quality rejection
- Aroma intensity tends to decline over time, so buyers often prioritize recent-crop lots and well-sealed packaging
Risks
Food Safety HighDried aromatic herbs and spices have documented global microbiological hazard concerns, including Salmonella and other pathogens, and can also be affected by mould growth when moisture control fails. Because dried leaves are often handled, dried, and stored across multiple steps and facilities, hygiene and validated contamination controls strongly influence import acceptance and recall risk.Apply Codex-aligned hygiene and hazard controls for spices/dried aromatic herbs; use validated microbial reduction treatments where permitted; implement supplier controls for moisture, sanitation, and environmental monitoring.
Mycotoxins MediumInadequate drying practices or humid storage/transport can promote mould growth and increase mycotoxin risk, particularly when leaves are dried in thicker layers, on contaminated surfaces, or re-wetted by rain/condensation.Control drying conditions (clean surfaces, thin layers, turning, protection from rain) and maintain dry storage; monitor moisture and warehouse humidity; ensure packaging prevents moisture ingress.
Plant Health MediumCitrus hystrix leaf supply depends on citrus tree health; citrus greening (HLB) is described by USDA as among the world’s most serious citrus diseases, with no cure, and can reduce productive tree life. Regional outbreaks or vector spread can reduce leaf availability and raise costs.Maintain phytosanitary programs and orchard monitoring; diversify sourcing across multiple producing areas; support suppliers with vector control and tree replacement planning.
Reputational Risk LowMarket-facing use of the name “kaffir lime leaves” can trigger negative reactions in some English-language markets due to the word’s association as a racial slur in certain contexts, creating avoidable brand and customer-relations risk.Adopt dual-labeling or preferred-market terminology (e.g., “makrut lime leaves”) and ensure marketing materials and specifications are aligned with customer policy.
Labor & Social- Terminology and labeling sensitivity: the term “kaffir” is considered objectionable in some contexts, leading some buyers and media to prefer “makrut lime”; misalignment can create reputational, customer-acceptance, or relabeling risk in destination markets
FAQ
What plant do dried makrut (kaffir) lime leaves come from?They come from the makrut lime tree, scientifically accepted as Citrus hystrix (Kew’s Plants of the World Online lists Citrus hystrix DC. as the accepted name).
Why do some buyers prefer the name “makrut lime leaves” instead of “kaffir lime leaves”?Some markets avoid the word “kaffir” because of its association as an offensive racial term in certain contexts; consumer-facing publications and some buyers therefore prefer “makrut,” which is tied to the Thai name used for the plant and its leaves.
What are the biggest food safety risks for dried makrut lime leaves in trade?As with other dried aromatic herbs and spices, key risks include microbiological contamination (notably Salmonella highlighted in FAO/WHO work on spices and dried aromatic herbs) and mould/mycotoxin risk when drying, storage, or transport allows moisture uptake.
