Sanitary Napkin Absorbency Testing: OEM Buyer Checklist Before Shipment

Absorbency testing turns a sanitary napkin claim into measurable performance. For OEM buyers, testing helps confirm whether the approved sample and bulk production match the intended use case.

For international buyers, the useful question is not only whether a supplier can make a sample. The real question is whether the factory can repeat the approved specification in bulk production, control quality, support private label packaging and communicate clearly before shipment.

Key absorbency test points

Useful checks include absorption speed, total capacity, rewet after pressure, side leakage, core distribution and product appearance after liquid intake.

• Absorption speed for first-use comfort.
• Total capacity for flow positioning.
• Rewet control for dryness.
• Side leakage simulation for overnight or heavy-flow SKUs.

When to test

Test during sample approval, pre-production confirmation and bulk production inspection. Repeat testing matters because materials and machine settings can change performance.

How buyers should document results

Keep the approved sample, test method, target range and inspection records. This makes future repeat orders easier to control.

FAQ for Importers

Is absorbency testing only for overnight pads?

No. Daily pads, liners, night pads and menstrual pants all need performance checks suitable for their use case.

What is rewet?

Rewet is the liquid that returns to the surface under pressure. Lower rewet usually means a drier wearing feel.

Can test targets be customized?

Yes. Targets should match the SKU positioning, destination market and price tier.
