The regular MOQ for single products is 500-1000 bottles (adjustable based on product type, e.g., 1000 pieces for masks), with flexible combinations supported for small-to-medium batch customization. Customization dimensions include: formula (active ingredients, skin type adaptation, compliance certifications such as EU COSMOS/US FDA), formulation type (serum, cream, mask, etc.), packaging (bottle design, logo printing, multilingual labels), and fragrance/color tone (tailored to target market preferences).
