4.Frequently Asked Questions (FAQ)

Q1: What does "20/410" mean in cosmetic packaging specifications?

A1: "20" refers to the nominal outer diameter of the bottle neck in millimeters (20mm). "410" represents the standard thread finish profile (1.5 thread turns). It fits any standard 20/410 cosmetic bottle.

Q2: Can this treatment pump handle thick creams or dense butter?

A2: This pump is calibrated for light to moderate viscosity liquids like serums, emulsions, foundations, and face oils. For dense body creams or solid butters, we recommend our wide-bore heavy lotion pumps.

Q3: Can dip tube lengths be customized for our specific bottle dimensions?

A3: Yes. Bulk orders include free automated dip tube trimming. We cut tubes to leave approximately 1.5mm to 2mm clearance from the bottle bottom for maximum formula extraction.

Q4: Are testing samples available prior to placing commercial orders?

A4: Absolutely. We provide complimentary standard sample sets for neck fitment verification and formula compatibility testing. Samples can be dispatched via DHL/FedEx within 48 hours.
