Hydranautics: N,N-Dimethylformamide-led volume
Among the 371 Miscellaneous Manufacturing facilities in this database, Hydranautics reports the 52nd-largest volume, placing it in the top 14% of its sector. Its reported volume is concentrated rather than spread: N,N-Dimethylformamide alone is 100% of the total. Carcinogen-classified chemicals make up 100% of the reported pounds, not just of the chemical count. Scale peers outside California include Morito Scovill Americas LLC DBA Scovill Fasteners and Abbott.
Concentrated means ≥60% of Hydranautics's pounds in one chemical - here N,N-Dimethylformamide at 100%. Not a toxicity score.
