Trying to work out what sort of timber this could be, some nice colours if i can get it dry without twisting to much.
Do those numbers mean anything to anyone ?
Could be nearly anything that is fast growing and cheap. A lot of sap wood there cut from young trees. Good luck with the not twisting, cupping,warping. As for numbers nothing to do with the timber species as far as I know.
HT/DB - I think that is just saying it is heat treated.
IPPC - International Plant Protection Convention, I think the EU is a big backer.
MY-010 - I'd guess Manufacture Year 2010?
What was delivered on the crates... where was the origin?
The thinner boards will be almost unusable, by the time they warp.
Depending on what you make, you'll need to work with the nail holes. Nail holes can create a nice recycled look anyway.
It's bloody hard work, depending on how dry the timber is.
Old Oregon and WRC is easily the best stuff to work. Old recycled Oregon from Old Growth forests can have really tight packed grain... Far superior to new school Oregon from plantations... Far superior in term of furniture grade. You can get some really nice big hanging beams out of some houses being demolished. Even roofing rafters, except roofing rafters have more nails to remove... roof battens nailed into them.
Even though you are probably attached to the timber you already have... if you think outside the square, you will be able to get some far better timbers from a house demolition site.... Old house... Also, potential for some beautiful Aussie Harwood Redgums, or similar. It's hard as nails, but beautiful colours. Old Oregon is about 7 times easier to work, especially with traditional hand tools.
However, I look at those piles of boards, and I'm thinking "book shelves".
Lots of work involved, planning down the timbers, gluing them up... to form the side walls and shelves.
With that distinctive end grain and colour variations it looks like Meranti.
Edit - the more I look at it the more I am certain it's Meranti. If you do decide to dry some out make sure you stack it properly with stickers in between each level of the stack. Should minimise cupping.
Meranti varies a lot in colour and density. The best stuff is OK boat building timber. All those colours are typical of meranti.
Meranti is cheap as chips, probably why they let us use it in high school wood work, all those years ago.
I think it's a tropical/jungle tree. So it either grows pretty quick and is sustaniable and cheap, or, its slow growing and the forests are getting raped, and its still cheap but will run out. If Simondo is right on what the stamp is then it might be the former.

my first thoughts where of maple also. If you intend joining for book shelves or the like alternate boards rings up rings down looking at the end grain. Helps cupping over the width of joined board. The tight rings suggest it came from small trees and will more than likely be prone to cupping.
we get alot of that stuff in pallets as well; . the stacking is the key to getting a good board out of it. once it dries it is rather good to work, particularly the bearers.
It isnt maranti but has very similar properties. meranti can have really heavy boards and really light ones in the same pack.
make sure you stack it really well with good ventilation between stacksyouve got some nice stuff there
The 1" (prob about 20mm) pieces used for the battens look like they are mainly edge cuts & sapwood. Although this will give the best feature, the sapwood can be a little chalky & not overly strong.
The pallet beams or main structure (1&1/2" ish) look like they come from a crosscut and prob downgraded due to the knots/splits/shakes etc. Either way, great character - just make sure you don't thickness them with blunt cutters.
No idea on the species of timber. I can shed a little light on the stamp.
Very basically - When goods are shipped to Australia, and timber is used on the pakaging, the stamp indicates the timber has been treated and is free to pass through quarantine.
Its all codes so the quarantine can determine country of origin etc.
The HT/DB in this case is the approved treatment used - look it up before you burn it as firewood or else you may end up toxic fumes in your lounge room.
i think it is meranti and sapwood rubbish cut from the outside of the tree, hence the massive variation in colour, cant really be used for anything commercial except pallets
but hey you can make whatever out of it, wont move much once dry and held together a 1000 screws
hope there are no termites near your shed, its a big feed for them, they are already salivating
