Under RCRA, when is a chemical considered hazardous waste?

Explanation:
Under RCRA, a chemical becomes hazardous waste if it is on EPA’s hazardous-waste lists (F, K, P, or U) or if it exhibits one or more hazardous characteristics: ignitability, corrosivity, reactivity, or toxicity. Being listed means it’s hazardous regardless of other properties, and the lists cover wastes from general sources (F), specific industries (K), and discarded commercial products (P and U). If a waste isn’t on a listed category, it can still be hazardous if it shows a characteristic, typically determined by standard tests like the TCLP for toxicity. Odor or simply being a solid does not decide hazard.
