I don't know how I can know for sure whether my chain is indeed hi test

Has anyone else had this doubt ?

1st chain supply will sell you a 1 foot sample for $10, which you
could compare with yours. G40 is HT chain.

Other than that, you are going to need a load tester. G40 breaks at
something over 15,000 lbs.
