This is where I was confused. I was looking at an obsolete version of that document that showed a permit required for 1,000 primers up to 9,999 primers, and a license from 10,000 up. Current document shows no permit required for less than 10,000 primers.ETA: if you go in this document https://www.mass.gov/doc/massachusetts-527-cmr-100-2015-edition-as-of-october-18-2019/download
search for 1.12.8.39.1.1.4 and look at paragraph (2). That references the chart 1.12.8.50 which defines permits/no permits/licenses required for each thing.
