Not necessarily, I’ve seen it slapped on all sorts of things, including PET and HDPE bottles and containers that don’t need a plasticiser anyway (BPA is mostly used in polycarbonate plastic and epoxy resins, can also be in PVC like phthalates). But yeah, I avoid anything made of polycarbonate (especially in food contact) for that reason, but with water bottles and things it’s not super common except for some sports water bottles here in Australia.
