Tippmann HPA tank stamps: I'm confused!

Question's for all you Air system guru's

I just pick up a Tippmann 26/3000 tanks. It does not have a DOT or TC stamp. It does have an ISO stamp (7866) on it as well as what I think is a PI stamp (0035). I can not find any info on if an ISO stamp is an allowed replacement for a DOT stamp here in the US.

So what the deal with this tank? Good to go in the US? Good to go in Canada? Not good to go any where? Retesting standards? Retesting allowed in the US? Any other info that can be given?

Heres is all the stamped info from the tank: (π = PI symbol)

5/8-18UNF TW GSM B096959
PW207BAR PH310BAR 0.64KG 0.42L 4.6mm
ISO7866 USA/M0816 TUV1 2015/05 π0035

The little I can figure out so far (but I'm not 100% on it all)

5/8-18UNF: Thread size

TW: Country or Origin: Tawian

GSM: Manufacturer: G-Shang Metal Corporation (I believe)

B09695: no clue

PW207BAR: Working pressure: about 3000psi

PH310BAR: Test pressure: just under 4500psi

0.64KG: It's a weight....I'm guessing the bottles weight

0.42L: Capacity: 25.63ci : sold as 26ci

4.6mm: Wall thickness: maybe?

ISO7866: ISO's regulation for refillable seamless gas cylinders

USA/M0816: Not positive but I think this is the DOT international Manufacturer approval number. Problem is I can only find DOT approval number up to m0813. m0813 belongs to G-Shang Metal Corporation. So super confused on this one

TUV1: Not a clue

2015/05: Born on date

π0035: PI stamp maybe????

I'm sure Tippmann/GI Sportz would not be selling tanks in the US that are not usable in the US, but I've never owned Tank without a DOT stamp so any help would be greatly appreciated

ISO tanks are higher in standards than DOT tanks.

Anyways, the tank is safe to use and safe to fill based on ISO 7866; you do not need DOT.
