落ちる (ochiru) is for physical falling, while 陥る (ochiiru) is for falling into a negative state or condition. Do not confuse them. 落ちる can also be used metaphorically in some cases (e.g., 眠りに落ちる 'fall asleep'), but 陥る is specifically for abstract negative states.
English 'fall into a category' is not translated with 落ちる. Use 分類される or 入る instead. Saying カテゴリーに落ちる sounds unnatural.
