The Ultimate Guide to Perfume Bottle Neck Finishes (FEA Standards Explained)

A neck finish is the threaded or crimped top of a perfume bottle that determines which caps and pumps will seal and fit - get it wrong and you get leaks or mismatched closures. Understanding it early saves rework and import headaches.

What a neck finish is

The neck finish is the standardized opening at the bottle top: its diameter, thread form and length. It is the interface between bottle, collar and pump.

FEA 15 / 18 / 20 mm

• FEA 15: common for small and sample sizes.
• FEA 18: the everyday standard for 30-50 ml.
• FEA 20: used for larger 100 ml bottles. All follow FEA (European) dimensional standards for interchangeability.

Crimp vs screw vs snap-on

• Crimp: pump is crimped on, tamper-evident, no cap thread.
• Screw: a threaded collar and cap screw on.
• Snap-on: pressed fit, faster but less secure.

Matching caps and pumps

Choose caps and pumps rated for the same FEA size and mount type so the closure seats cleanly and the spray works first time.

Common leak mistakes

• Wrong neck size for the selected pump.
• Mixed crimp and screw components.
• Damaged collar threads from over-tightening.
