Evidence & Review

Production checkpoints, agreed test methods and document scope help buyers evaluate each approved project.

PRODUCTION & QUALITY EVIDENCE

Real checkpoints, shown in context.

Partner-provided production records help buyers understand where material, product and delivery reviews take place. Project-specific evidence remains subject to document and scope confirmation.

**Incoming material inspection**Selected raw materials are checked before release to production.

**Leakage test in the laboratory**Sample construction is reviewed against the agreed test method.

**Raw-material storage**Roll materials are staged for controlled production use.

**Export loading**Finished goods move from packing and warehouse review to dispatch.

REFERENCE METHODS

Numbers need a method.

Sanitary pads: Reference absorption values use GB/T 8939-2018 synthetic menstrual fluid; approved samples and agreed limits control the project.
Period pants: Reference saturated absorption uses 0.9% saline and the stated GB/T 8939 method; rewet is reviewed separately.
Personal-care wipes: Substrate weight, pH, seal integrity and microbiological controls are reviewed by formula, format and target market.
Dispersible tissue: Any flushability or dispersibility claim requires the applicable test evidence, including GB/T 40181-2021 where relevant.
