No legitimate testing lab is going to accept samples through the mail. And sending cannabis/cannabis products through the mail is a federal offense as cannabis is still a Schedule 1 drug under federal law and both the sender and receiver can be charged.
"mailing marijuana in an amount less than 50 kilos carries a maximum penalty of up to five years in prison and a fine of up to $250,000"
Your best bet would be to drive to Maine or Vermont but you would need to find out if you need to be a licensed grower and be a resident of either state as crossing state lines with cannabis is illegal so they would essentially be involved in drug trafficking by receiving any cannabis you brought across state lines. If they check ID and you show them a NY ID it's doubtful they would accept any samples you bring them. Nobody is going to put their business at risk for the $200 they'd get for testing some brownies.
Iron labs will test whatever u bring them, no questions asked on license status.
That's only if you live in Michigan or Oregon and drop the samples off in person or use their courier service to pick them up. They do not accept samples in the mail.
