What are the rules concerning cutting down forest and sawing your own timber? For instance, are you allowed to build a garage with it, or do you have to use graded timber?
The neighbor has a machine hall where the roof collapsed one snowy winter. They received nothing from the insurance company because it was built with their own unclassified timber. I suspect that, in addition, the trusses were self-made and not properly dimensioned. But the lesson is that insurance companies can complicate things if it is not done according to standards. However, I can't imagine there is any prohibition on this.
tompaah7503's opinions are sensible. If you still want to use your own timber, you can obtain the sorting standard SS 23 01 20 and use it. It largely depends on minimizing the presence of knots. If you have your own old forest, it shouldn't be a major issue to saw timber in the highest grades, C30 and C35, which are actually quite difficult to find in the general market. Then it's important to make the correct calculations.
The purchased timber is usually planed and at least C14. The homemade sawn timber is finely sawn. If we talk about dimensions from 45x70 and upwards.
Sure, but how can you tell if C14 or C24 were used when the construction has collapsed? And then normally there is no need for any durability calculation on smaller buildings, at least they haven't asked it from me when I've applied for building permits.
One may build with any "skit" as long as it holds. And nothing else is prescribed.
You won't get anything from insurance if the wall, built with timber that's too weak but correctly classified, collapses either.
However, everything that is structurally calculated must be built with prescribed materials.

You probably need some kind of authorization to reclassify if the insurance company is to agree to it. Not that there is a risk if you do it right.
If one has the opportunity to build with their own timber, they should take advantage of it. The conditions are favorable for an end result that is superior compared to what is the case with the junk timber that is commonly available. However, one must know how to select the timber and how to dimension it.
Most construction timber sold is machine-sorted.

I usually build most things with my own timber and it's definitely better than what you normally buy, but I don't send scrap timber for sawing, you can sell that instead. I'm going to build a part this summer with timber I've acquired from a sawmill and it's only pine, but it will do since it was at the right price.

Otherwise, one can build roofs and similar structures with the right timber and then save on other things. One can instead saw panels or whatever else is needed.
The graded timber is usually stamped at regular intervals along its entire length. Can you really grade it yourself? The sawmills perform a deflection test on the graded timber.
One must be certified to grade oneself. But for less demanding parts, the timber can be counted as K12/C14 (T0) old Ö-timber...
According to SS 23 01 20 and SS-EN 1611-1
