You mentioned that if it was cleaned more, it could go up to tiger grade or something to that effect.
Well as people say, you gotta get your hands dirty to really get to the root of the issue! But probably not here.

The "incense grade" issue.
As far as I recall, I started using this term in 2011 and don't remember it being used before. Back then, it simply meant "using wood that would otherwise be sold as incense for burning, to extract oil", i.e. finished chips. I didn't realize how aggressively the term could be abused, and how much wiggle room could be made to accommodate far lower grades of agarwood.
Now there are two other grade of wood which can match (and sometimes even beat) incense grade wood extractions, and they are:
1) the last 2 stages of cleaning/carving Super & higher grades of wood. I have to emphasize that I am not talking about all carving scrap material. Only about 10% of the shavings qualify as high quality, of incense-grade caliber (I call these oils "cheat grade").
2) the uppermost end of oil-grade wood.
So what are the cans of worms I was referring to?
In the case of shavings, its next to impossible to know for sure that the shavings were from the last 2 stages of carving. Either the tree has to be your own (in which case you can instruct the pakerja how to collect the shavings in different piles according to grade), or you have to have reliable suppliers who are willing to follow your instructions. And what actually happens...? ALL the shavings are collected and combined together.
In the case of oil-grade wood, its subjective. Who defines what's high enough quality? An unscrupulous seller could stretch the definition of "high quality oil grade" wood to include what I for instance may consider bunk wood. To me, high quality oil grade wood can be defined as something that isn't terribly impressive visually, however it can be valued by the Chinese, Japanese, and Taiwanese incense masters.
Here's an example of what proper sorting according to grade looks like (visually, its almost impossible to discern between the 4 grades of shavings here):
And here's an example of what high quality oil grade wood *can* look like (and just because a batch of oil grade wood looks the same as this, it does not automatically qualify it as high grade):
I hope you can see what the issue is. "Incense grade" or "high grade" can be used as a catch-all deliberately to smudge the lines separating high grade vs low grade oud oils. Based on pictures and videos alone, customers would have no clue if the shavings were from the last 2 stages of carving, or if the oil grade wood was indeed high/incense grade.
