Cultivated Qinan chips & raw materials.
Hand-cleaned slivers, burner chips, extraction stock and milled powder from grafted Qinan in Guanzhu — graded by resin density and moisture.
Botanical Taxonomy
Aquilaria sinensis (Lour.) Spreng. (Cultivated Qinan)
Regulatory Status
CITES Appendix II Artificial Propagation (Source 'A')
Artisanal Purity
Processing: Hand-cleaned white wood removal
Authentic triage of golden-grain Qinan chips and bulk wholesale lots.
Experience the actual physical handling inside our Guanzhu processing center. Every kilogram of cultivated Dianbai Qinan passes through multi-tier bamboo and stainless sieves to eliminate residual wood dust, loose sapwood fibers, and irregular fragments before certified batch packaging.
Manual agitation removes lightweight white wood particles, isolating pure resin-dense core fragments.
Calibrated for consistent heat diffusion in kōdō warmers and predictable yield in steam distillers.
Structured Raw Material Formats
Standardized harvest cuts sorted for perfumers, incense ateliers, and extractors.
Sinking & semi-sinking chips
Ceremonial & retail burning. Dense resin veins, natural sink capacity, deep lingering volatile sesquiterpenes.
Burner slivers & thin cuts
Clean low-ash heating. Sub-millimeter slices tailored for electric heaters and traditional kōdō ceremonies without carbon scorch.
Distillation & extraction stock
High-oleoresin small cuts. Optimized surface area for low-temperature hydro-distillation and supercritical CO2 extraction.
Milled Qinan powder
60–120 mesh for incense making. Pure pulverized heartwood without nanmu bark adulteration or artificial burning aids.
Custom wholesale lots
Sorted by cultivar and cut size. Bulk parcels sorted by Dianbai mother-tree line (Green Oil / Iron Head / Tiger Skin) for brand formulation and scalable manufacturing.
Graded by sink test, cleaning level and moisture — never resin-injected.
In traditional Chinese olfactory classification and authentic Dianbai trade standards, true Qinan grading is an empirical physical science determined strictly by water displacement, natural resin cellular occlusion, and unadulterated mass.
Optical black appearance without verified mass density is systematically discarded. Artificial resin pressure-injection or chemical coloration compromises volatile integrity and is completely prohibited in our processing protocols.
Every export lot undergoes calibrated hydro-density validation: heartwood containing over 55% resin volume naturally achieves positive sinking displacement (>1.0 g/cm³), establishing immutable quality parameters.
Laboratory certificates of analysis accompany each verified container parcel.
Sinking Grade (沉水)
Highest resin density, sinks in water (>1.0 g/cm³), ceremonial & collector retail. Jet-black oil canal saturation.
Semi-Sinking Grade (半沉水)
Balanced resin-to-fiber ratio (0.85–0.98 g/cm³), specialty retail & gifting. Waterline suspension, rich honey-cool baseline.
Extraction & Burner Grade (香薰/萃取)
Aromatic resinous cuts (<0.85 g/cm³), distillation & incense production. High surface-to-mass ratio for full volatile release.

Standardized Preparation & Structural Protection
Every batch follows strict post-harvest protocols to protect volatile terpenes and guarantee purity.
Hand-cleaned sapwood removal
Artisanal manual gouging removing all non-resinous white wood fiber under 20x inspection lighting.
Moisture check before sealing
Halogen balance moisture determination calibrated to ensure water content remains strictly ≤10% before packaging.
Nitrogen / vacuum barrier bags
Multi-layer aluminium barrier film, sealed under inert nitrogen flush to prevent volatile terpene oxidation in transit.
Batch traceability label
Tamper-evident label indicating harvest date, Dianbai grove GPS coordinates, distillation batch code, and CITES reference.
Inspection and Compliance Verification
Transparent empirical authentication records supplied for international import authorities and brand chemists.
Sink & moisture test per lot
Video and digital hydrostatic scale report provided for every graded batch.
Unvarnished, zero synthetic oil or glue
GC-MS chromatogram guarantee certifying zero paraffin, mineral oils, or synthetic fragrance boosters.
CITES & phytosanitary dossier support
National Endangered Species Import & Export Office permits and customs quarantine certificates included.
