**A gaharu inoculation service (jasa inokulasi) drills mature Aquilaria trees and introduces a fungal or organic inoculum to trigger resin — gubal — formation, turning plain wood into tradeable gaharu over roughly one to three years. Results vary by tree, method, and site, and no honest service can guarantee a grade or a yield.**
What does a gaharu inoculation service actually do?
Natural gaharu (gaharu alam) forms only when a wild Aquilaria tree is wounded and slowly colonised by fungi over years. It is rare, unpredictable, and the reason wild stands were stripped across Kalimantan and Papua. Inoculation reproduces that stress on purpose. Trained crews drill a planned pattern of holes into a mature trunk and introduce an inoculant — a fungal culture, an organic paste, or a mineral solution — so the tree defends the wound by laying down fragrant resin. Over the following months that resin darkens the wood into gubal and kemedangan grades that can be harvested, cleaned, sorted, and sold.
The service matters because a plantation of healthy, un-inoculated Aquilaria produces almost no gaharu at all. Inoculation is the step that converts a standing tree into a resin asset. But it stays a biological process, not a production line: two trees on the same block, inoculated on the same day, can finish at different grades.
Bali Premium Trip’s trade desk arranges inoculation through vetted licensed field partners. We do not own the plantation or the outcome — we coordinate the crew, help select a method, and keep the export-readiness paperwork trail clean.
How much does a gaharu inoculation service cost?
Cost is quoted per tree and per project, driven by trunk diameter, how many holes each tree takes, the inoculant grade, and travel to your site. The table below is indicative as of 2026 and confirmed only on a written quote.
| Service tier | What it includes | Typical induction before harvest | Indicative cost basis (2026) |
|---|---|---|---|
| Basic inokulasi | Drilling plus a single organic or fungal inoculum pass, roughly 10–20 holes per tree | 12–18 months | about Rp 75,000–150,000 per tree |
| Standard induction | Drilling plus a graded fungal inoculant and one follow-up inspection | 18–30 months | about Rp 150,000–250,000 per tree |
| Premium extended induction | Denser hole pattern, higher-grade inoculant, staged reinjection and monitoring | 24–36+ months | about Rp 250,000–350,000 per tree |
Those are indicative service costs, not a promise of grade. What actually moves your bill:
- Tree readiness — Aquilaria usually needs about 5–8 years and enough trunk diameter before it holds resin worth inducing; trees keep maturing toward full harvest weight over roughly 7–15 years.
- Inoculant grade — cheap pastes cost less but tend to give thinner resin, while graded fungal cultures cost more per tree.
- Hole density and labour — more holes and skilled crews raise cost and often widen resin coverage.
- Site logistics — remote plots add travel and lodging to the quote.
- Monitoring — staged reinjection and inspection across the induction window.
What quality and price can inoculated gaharu reach?
Inoculated wood rarely matches the rarest natural grades — tokolantaikayu.net (May 2025) put whole-gubal Super Kynam/Kyara at Rp 1–1.5 billion per kg — but cultivated chips still carry real value and, crucially, a documentable legal origin. Indicative harvest values, per Silvikultur UGM figures published October 2016:
| Harvest grade | Local term | Indicative value |
|---|---|---|
| Top resinous chips | gubal double super | Rp 30–40 million/kg |
| Mid resin chips | super tanggung / TG-B | Rp 5–30 million/kg |
| Lighter resin wood | kemedangan | Rp 2–5 million/kg |
| Low grade / powder | gaharu teri, abu/bubuk | Rp 20,000–2 million/kg |
Our canonical brand band for buyers repeats site-wide: plantation gaharu chips run USD 500-7,000/kg (grade-dependent) and oud/agarwood oil USD 30,000-80,000/kg (as of 2026, indicative; a final quote confirms grade and scope). Inoculated output typically sits in the lower and middle of that chip band — good economics for a cultivated block, without pretending it will hit wild-kynam prices.
How does booking a gaharu inoculation quote work?
- Send your site details. Message the trade desk with tree count, location, and approximate age of your Aquilaria.
- Free scoping. Our field partner assesses diameter, tree health, and access, then recommends whether the block is ready and which method suits it.
- Written quote in 24 business hours. You receive a per-tree and per-project price, method, hole plan, and induction window in writing.
- Crew scheduling and inoculation. On approval, the licensed crew drills, inoculates, and logs each treated tree for your origin trail.
- Induction, harvest, and export-readiness support. After the induction window, crews inspect before cutting, and we help assemble the legal-origin paperwork your CITES export will need.

What must you confirm before you export the harvest?
Aquilaria spp. is listed on CITES Appendix II, so legal export requires a CITES export permit plus proof of legal origin — and, for any wild-sourced material, a BKSDA (Balai Konservasi Sumber Daya Alam) recommendation. Guidance from 2023–2025 also points to KLHK origin documentation and ASGARIN membership, with CITES permits typically valid up to about six months and processing running up to roughly 60 days for some destinations. Inoculated, plantation-grown gaharu is cultivated origin, which is far easier to document than wild harvest — one of the strongest reasons to inoculate rather than log wild trees. Always confirm current requirements with the CITES Management Authority (Indonesia) and your import country. We never sell permit certainty or a customs guarantee.
Frequently Asked Questions
How long after inoculation can gaharu be harvested?
Most induction runs 12–36 months before a worthwhile harvest, and longer usually means more resin. Basic inokulasi may show colour within a year, while premium staged induction often waits 24–36 months. There is no fixed date — resin builds at the tree’s own pace, so crews inspect and test before cutting rather than harvesting on a calendar.
Does inoculated gaharu sell for less than natural wild gaharu?
Usually, yes. The rarest natural gubal — kynam or kyara — reached Rp 1–1.5 billion per kg in tokolantaikayu.net’s May 2025 table, far above typical inoculated output. Cultivated chips still command real value, with our indicative brand band at USD 500–7,000 per kg by grade (as of 2026), and legal cultivated origin is much easier to document for export.
Can you guarantee my trees will produce high-grade gubal?
No, and treat anyone who promises it as a warning sign. Inoculation is biology: grade and yield vary with tree health, inoculant, method, and site, even across identical trees on one block. Our partners apply proven techniques to improve the odds, but Bali Premium Trip sells a service and coordination — never a guaranteed grade, weight, or price.
What tree age or size do I need before inoculation?
Aquilaria is generally inoculated once it is roughly 5–8 years old with enough trunk diameter to hold resin; trees keep maturing toward full harvest weight over about 7–15 years. Younger, thin stems rarely repay the cost. During free scoping our crew checks diameter and health before recommending whether a block is ready to treat.
Do I need a CITES permit to export inoculated gaharu?
Yes. Aquilaria is CITES Appendix II, so legal export requires a CITES permit plus proof of legal origin and, for wild sources, a BKSDA recommendation. Inoculated, plantation-grown wood is cultivated origin and easier to document. Confirm current rules with the CITES Management Authority (Indonesia) and your import country; we are a broker, not a permit authority.
