Indonesia is, by a wide margin, the most species-diverse agarwood-producing country in the world, and one of the largest by export volume. Where most producing countries rely on one or two dominant species, Indonesia's agarwood industry, known domestically as gaharu, spans the bulk of both genera covered in our guide to Aquilaria vs Gyrinops, harvested across an archipelago that stretches from Sumatra to Papua.
This guide covers what's documented about Indonesia's species distribution, regional sourcing, grading conventions, and the CITES quota system that governs legal export, the most heavily regulated and most complex of any origin covered in this hub.
Gaharu: Indonesia's Agarwood Industry
"Gaharu" is the Indonesian and Malay term for agarwood, used throughout Indonesia's domestic trade, regulation, and research literature. Indonesia's gaharu industry is built on wild harvest from natural forest far more than most other major producing countries covered in this hub, though plantation cultivation has expanded here as well, for the same reasons covered in our guide to wild vs plantation agarwood.
The Most Species-Diverse Producing Country
Research on agarwood-producing taxa indicates that around 15 of the roughly 21 recognised Aquilaria species and 7 of the roughly 9 recognised Gyrinops species occur in Indonesia, a striking concentration of the world's total agarwood-producing species diversity within a single country's borders. No other country covered in this hub comes close to that range, which is part of why Indonesian gaharu spans such a wide variety of regional names, grades, and price points compared with single-species origins like Vietnam or Cambodia.
Two Geographic Groups: Malaccensis and Filaria
Indonesian agarwood research conventionally splits the country's producing species into two geographic groups, named after their respective dominant species. The "Malaccensis group" covers western Indonesia, principally Sumatra and Kalimantan, and includes Aquilaria malaccensis, Aquilaria hirta, Aquilaria beccariana, and Aquilaria microcarpa. The "Filaria group" covers eastern Indonesia, including Papua, West Papua, Maluku, and Sulawesi, and includes Aquilaria filaria and Aquilaria cumingiana alongside several Gyrinops species: Gyrinops versteegii, Gyrinops ledermannii, Gyrinops moluccana, Gyrinops decipiens, Gyrinops caudata, Gyrinops podocarpus, and Gyrinops salicifolia.
This grouping is also the basis for how Indonesia's CITES export quotas are structured, covered later in this guide: rather than setting a separate quota for every individual species, Indonesia's quota system has historically managed the two groups as broad categories.
Sumatra, Kalimantan, Papua, and Beyond
Within the Malaccensis group's range, Sumatra and Kalimantan are the most significant sources of Aquilaria malaccensis, with notable population concentrations reported in Sumatra and eastern Kalimantan specifically. Within the Filaria group's range, Papua and West Papua are the primary sources of Aquilaria filaria, alongside parts of Maluku and Sulawesi, while Gyrinops versteegii, often referred to locally by names such as "ketimunan," is closely associated with eastern Indonesian islands in the Nusa Tenggara region, including Flores and Sumbawa. Smaller gaharu-producing areas have also been documented in parts of West Java.

Aquilaria vs Gyrinops: Understanding Agarwood's Two GeneraHow Indonesian Gaharu Is Graded
Indonesia's national standard for gaharu (SNI) broadly classifies the material into categories including gubal gaharu, resin-impregnated wood with substantial resin content, kemedangan, a lower-resin gradation, and serbuk gaharu, or gaharu powder, with grading criteria based on colour, weight, and scent. Underneath these broad categories, trade and research literature documents considerably more granular regional grade names. Studies of gaharu from West Sumatra, for example, document specific grades such as Super AB, Super BC, kemedangan C, teri C, and kacangan C.
As with grading systems in other producing countries covered in this hub, these names and boundaries are not applied with full national consistency, and the same grade name can refer to somewhat different material depending on the region and the trader. Researchers have also worked on more objective, chemistry-based grading methods, including analysis of specific resin compounds correlated with grade, but trade-floor grading in Indonesia still relies primarily on the traditional sensory criteria of colour, weight, and smell.
Indonesia's CITES Quota System
Indonesia operates one of the more formally structured CITES management systems among agarwood-producing countries. Indonesia's national science agency, historically the Indonesian Institute of Sciences (LIPI), since reorganised into the National Research and Innovation Agency (BRIN), has served as the country's CITES Scientific Authority for agarwood, providing the species distribution and population data used to assess sustainable harvest levels. The Ministry of Environment and Forestry's Directorate General of Forest Protection and Nature Conservation, historically referred to by the acronym PHKA, has been responsible for setting and issuing the actual annual harvest and export quotas, a role it has held since first issuing quotas for Aquilaria malaccensis in 1996.
Quotas are set through a non-detriment finding process, drawing on field sampling in major producing areas alongside production data reported by exporters, forestry district offices, trade associations, local traders, and farmers. Reported quota levels have historically been allocated by the two geographic groups described above; figures cited in CITES documentation include a Malaccensis group quota around 50,000 kilograms and a Filaria group quota around 125,000 kilograms, though exact figures are reviewed and can change from one quota cycle to the next. An industry body, the Indonesian Gaharu Exporter Association (ASGARIN), works with the regulating authority to coordinate harvest activity and distribute quota allocations among its member exporters.
Indonesian Agarwood in the Market Today
Indonesia remains one of the largest sources of agarwood entering global trade, drawing on a far wider species base than most competing origins. For buyers, this breadth is a double-edged feature: it means a wider range of authentic regional character and price points than almost any other origin, but it also means species and regional claims, "Kalimantan," "Papua," "Super AB," and similar terms, are harder to verify without documentation than for single-species origins, simply because there is more legitimate variety for misrepresentation to hide behind. The same seller-documentation principles covered in our quality and authenticity guide apply here, with particular weight given to species and regional sourcing claims.
