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 market shampoo labeling, ingredients must be listed in descending order of concentration using INCI nomenclature.
  • Net contents must appear in both fluid ounces and milliliters, typically on the principal display panel.
  • We recommend including batch codes, manufacturing dates, and distributor information as well.
  • Our MOQ for shampoo is 5,000 units, with sampling taking 2-3 weeks including label verification.
  • We can provide FDA-compliant labeling templates and support necessary documentation testing through our in-house lab capabilities.
