When you are shopping around to choose your oud (agarwood) chips, you would like to purchase genuine oud (who wouldn't?). There are many different techniques which you can use. Below are just a few.
Disclaimer: Based on my experiences only, everyone might have different methods, feel free to use whatever suits you
There are two basic ones.
(Evergreen Forest's cultivated agarwood for sustainable future)
Multiple oil veins are visible ( Oil vein: resins, dark lines around the wood). If you could not see any threads but solid colour, it means someone has tampered the wood.
Pick one piece up and have a deep smell of it, if it has a sharp, tangy, alcohol smell, chances are it was not a genuine one.
If you are serious about buying it, ask for a sample to bring home or if not allow, buy a small piece to test:
(The above image shows heated resin, the shiny black surface was the oil in the wood, come out in high temperature and release a woody fragrance ) Here is another image of a small woodchip with resin Shiny resin after 10 minutes of heating at 180 degree
You can place a small sample of agarwood woodchip inside a pot.
Turn on the heat; you could see bubble derived from the resin. At this point, the agarwood fragrance releases from the wood.

There were no 100% answers on this unless you would bring it to the lab (the best method, click here) which could be quite costly. However, there is a simple technique you could use:
Pay attention to the "hole" where agarwood forms around
Where does it come from? See below for side view.
Vertical view (internal infection)
The hole was drilled, initiating the creation of agarwood forming around the wound, hence the big hole. Why not a small hole? It is possible to create, but it is a harder job.
With cultivated, the infected wood will be created around its wound, which is the hole, to protect it from outside attack. The hole was drilled, nailed by tools, so it is quite a distinctive feature of cultivated agarwood.
Wild woodchip ( in this case, it was from Nha Trang Vietnam), has multiple holes which are smaller in size, usually created by insects, ants ( PLEASE NOTE THIS IS A GENERAL GUIDE ONLY as if a seller wanted to cheat, he would do anything to cover his "products")
Below is some natural infected wood log in horizontal and vertical view; it is not possible with current inoculation technology to create these type of infection pattern (WILD AGARWOOD).
Generally, sellers would store agarwood together. Most of the time, they classify these oud chips based on its resin. You may heard the term "incense grade", "sinking grade", "double king", "AAA". You can observe multiple pieces to see a different type of holes. Cultivated woodchip has an average of several centimetres wide while the wild one has a smaller hole generally.

Wild Sumatra Agarwood chip (compared the holes, smaller, caused by insects, or fungi)
You might have to scroll up to see the cultivated woodchip in the very first image (multiple pieces and holes size is more significant than wild one)
Big size of wild agarwood pieces is for decor, figurine, multiple religious beads. The powder of it during the producing process would be the material to make incenses, and oil distillation.
The scent profile is also different; however, with this method, you must know what to look for when sampling. For example, some oud chips are sweeter, while others are spicier or a mixture of both. Either way, the experience should be pleasant. It is a good idea to bring a portable incense heater with you (for example, the Kodutu incense heater)
To make even more challenging, please look at the cultivated agarwood below, it is tough to tell by just looking at it.

If the chips were collected above the hole or vertically cut, it is difficult to tell if these are cultivated wood.
I would like to show you side by side, wild vs cultivated agarwood.
You could tell by just looking at the picture, on the left: wild and on the right: cultivated.
There is limited agarwood on that tree as it is the frame only. The tree was dead suffering multiple wounds and unable to recover. Agarwood has been scrapped off (collected) from this tree leaving the frame.
Finally, for a laugh only and to let you know many unscrupulous con-man sellers out there, please look at this "sinking" rock, wood, plastic grade.

Sinking grade? Check open-end for woodchip. If it is solid, shake to see there is noise. Feel it. If in doubt, x-ray it.
More sinking grade?
