How do you test pump output consistency for thick creams and body butters?

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 thick creams and body butters, pump consistency is mostly about matching viscosity to the right dispensing system first (pump type, orifice size, dip tube, and whether an airless package is needed).
• We start with packaging compatibility selection, then validate on filled samples before you commit to bulk packaging.
• Our consistency check is practical: we prime the pump, then run repeated strokes and weigh each dispense to calculate average output and variation (we can share the test record as part of your QC file).
• We also do “real use” simulations to watch for clogging, backflow, stringing, and separation impacts on output, including checks after short-term storage so you can confirm performance before mass production.
• Typical minimum order is 1000-3000 units depending on packaging/formula complexity (simple items can start around 1000; more complex sets often start around 3000).
• After sample confirmation, bulk production is usually 10-20 working days; packaging ordering commonly takes 10-30 working days.
• We can support documentation and third-party testing/inspection coordination (report tracking available), but we do not guarantee regulatory outcomes.
