Aggregate companies outside of the U.S. NSSGA is active in numerous international alliances, and we welcome international aggregates producers in our membership.
Companies must operate only a single quarry/operation; employ less than 10 non-office employees; and record less than 1500 non-office man hours per year. NSSGA provides a platform for small producers to be heard and to have their positions represented far beyond what any one company could do alone.
