No. The New Mexico PFAS rule (20.13.2 NMAC) does not exempt small businesses, and there is no size threshold (no gross-receipts or headcount carve-out). A one-person online shop selling cookware or food packaging into New Mexico is in scope.
What is free: the NMPRS portal itself and NMED's official label artwork. The $2,500 initial fee applies to reporting regardless of size, which is a real fixed cost for a small brand.
Because there is no exemption, the realistic mitigation is knowing precisely which of your products contain intentionally added PFAS and getting their report + label done before the deadlines.
