How to Shortlist the Right OEM

• Sonic vs rotating: Sonic (31k–40k VPM) dominates private labels; rotating suits deep-stain positioning.

• Certs by market: EU needs CE + EN ISO 13485 mindset; US needs FDA facility registration + FCC; UK/MENA often ask for BSCI/BRC.

• Hidden cost: Custom mold + package + motor tuning can outweigh unit price — ask for tooling amortization.

• One-stop vs pure powered: If you plan bundles (brush + floss + irrigator), a full-range partner like Freshday reduces supplier count.
