Quick Answer (for busy buyers)

Here’s the buyer-first summary. If your brand name is on the label, you usually act as the responsible person and must ensure the listing is submitted and kept current.

  • For US skincare labeling, ingredients must be listed in descending order of concentration using INCI nomenclature.
  • Net contents must appear in both US customary units (fl oz, oz) and metric (mL, g).
  • We recommend including batch codes, manufacturing dates, and distributor information.
  • Our MOQ starts at 5,000 units per SKU, with sampling taking 2-3 weeks including label mockups.
  • We provide FDA-compliant labeling documentation and can support testing through our ISO 17025 lab partners.
  • Lead time for production with approved labeling is typically 6-8 weeks.
