Do I need to be a large contract manufacturer to join, or can small-batch labs sign up?

Small-batch labs and independent formulators are exactly who AJ Cosmo Labs is built for. The marketplace explicitly serves indie and emerging brands that need low MOQs — often 100 to 500 units — and USA-based manufacturing. If you specialize in small runs of micellar water, toners, or cleansing formulations, your profile will be competitive in the marketplace, not buried by larger co-packers.
