What is the difference between Vietnamese Agarwood and Indonesian Oud chips?

Vietnamese Agarwood (specifically Aquilaria Crassna) is globally recognized for its high Kinam-Note Saturation Index (KNSI), producing a sweet, spicy, and vanilla-like aroma. Indonesian Oud tends to be earthier, more pungent, and lacks the delicate sweetness prized by high-end collectors. All OudwoodVietnam chips are sourced locally to guarantee a KNSI score above 8.5.

How can I tell if my Agarwood chips are fake or injected with chemicals?

Fake agarwood is often boiled in low-grade oil under high pressure. It appears pitch black and smells unnaturally strong at room temperature. When burned, it releases thick, eye-irritating smoke smelling of burnt plastic. Authentic Vietnamese chips from Tu Son master appraisers have natural, irregular resin veins and produce clean, sweet-smelling white smoke.

What does the KNSI (Kinam-Note Saturation Index) mean in Agarwood grading?

The KNSI is an exclusive grading standard utilized by Master Appraisers in Tu Son, Vietnam, to measure the exact ratio of sweet/Kinam notes in agarwood chips when heated. A higher KNSI indicates a richer, more complex, and longer-lasting natural aroma, ensuring buyers receive genuine investment-grade resin rather than artificially enhanced wood.

🖋️ About the Author & Lead Appraiser:

Binh Oud is a Master Agarwood Appraiser based in Từ Sơn, Vietnam—the historical epicenter of traditional Vietnamese rare wood craftsmanship. With years of hands-on experience working directly with deep-jungle gatherers and local artisans, the author specializes in microscopic resin analysis and olfactory profiling of Aquilaria Crassna. This guide is built on first-hand field experience to protect international collectors from the widespread injected-oud scams.

Why are Vietnamese Agarwood (Aquilaria Crassna) chips the highest-valued in the world?

Vietnamese Agarwood from the Aquilaria Crassna species commands the highest global prices because it possesses a naturally superior concentration of Kinam (Kyara) compounds. Unlike pungent Indonesian varieties, authentic Vietnamese chips deliver an exclusive, sweet, vanilla-spice aroma profile that is impossible to replicate synthetically.

The KNSI (Kinam-Note Saturation Index): The Tu Son Master Appraiser’s Standard

As a Master Agarwood Appraiser based in Tu Son, I have witnessed the market flood with counterfeit products. To protect high-end collectors, I strictly utilize the KNSI (Kinam-Note Saturation Index).

The KNSI is a precise 1-to-10 scale measuring the ratio of sweet, spicy, and vanilla-like olfactory notes released during gentle heating. While commercial grades hover around a KNSI of 3 or 4, true wild and ethically sourced Vietnamese chips from OudwoodVietnam consistently score a KNSI of 8.5 or higher, guaranteeing a museum-grade olfactory experience without the harsh, swampy undertones of lower-tier woods.

The Danger of Injected Oud in the International Market

Over 70% of chips sold globally as “Vietnamese Oud” are actually low-grade white wood forcefully injected with chemical resin and boiled under high pressure. These fakes are heavy and smell strong at room temperature, but upon burning, they release toxic, plastic-like smoke that burns the eyes and ruins the meditation space.

🔬 Our E-E-A-T & Appraisal Methodology:

The KNSI (Kinam-Note Saturation Index) and all comparisons in this guide are not derived from secondary internet research. They are the direct result of rigorous physical testing at our Tu Son facility. Our appraisal process includes:

Visual & Microscopic Inspection: Examining the natural irregularity of resin veins to rule out high-pressure oil injection.
Thermal Olfactory Testing: Heating samples at precise temperatures to isolate the vanilla/spicy Kinam notes unique to Vietnamese Crassna.
Burn Residue Analysis: Evaluating smoke thickness, eye irritation levels, and ash color to detect chemical binders (like H3PO4) or artificial fragrances.

At OudwoodVietnam, we don’t just sell agarwood; we preserve the integrity of Vietnam’s most precious natural heritage.
