1. Agarwood Chip Grading Chart (Visual Infographic)
A. By Resin Content (Traditional Grading)
| Grade | Appearance | Resin Content | Aroma Intensity | Market Price Level |
|---|---|---|---|---|
| Kyara / Kinam | Dark brown-black, dense | 80–100% | Very strong, lingering | Ultra-premium |
| Super Grade | Blackish-brown | 60–80% | Strong, sweet-woody | Premium |
| Grade A | Brown with black streaks | 40–60% | Medium-strong | High |
| Grade B | Brown with light resin | 20–40% | Mild-woody | Medium |
| Grade C | Pale brown/yellowish | <20% | Weak aroma | Low |
(Chart visual: gradient from pale wood to fully black resin)
B. By Size & Shape (Commercial Grading)
- Chunk — large natural pieces (collector grade)
- Flake — thin pieces, high resin for incense
- Chip — small cut pieces for distillation or incense
- Powder — ground form for oil extraction

3. Suggested Training Flow
- Start with chip appearance samples (real or photos).
- Show grading table side-by-side with oil quality chart.
- Connect physical chip grade to extraction yield & GC–MS profile.
- Highlight sustainability benefits of grading at the source.
