“In the United States, the Small Business Administration establishes small business size standards on an industry-by-industry basis, but generally specifies a small business as having fewer than 500 employees for manufacturing businesses and less than $7.5 million in annual receipts for most non-manufacturing businesses.[4][5] The definition can vary by circumstance—for example, a small business having fewer than 25 full-time equivalent employees with average annual wages below $50,000 qualifies for a tax credit under the health care reform bill Patient Protection and Affordable Care Act.[6]” https://en.wikipedia.org/wiki/Small_business#Size_definition...
A sub 500 person factory could easily be too large for this bill, on the other hand an ACA small business would be tiny by comparison.
