The absorbent core is the heart of a diaper. Low-grade SAP, pulp, or uneven SAP distribution can cause leakage and poor user experience.
How to avoid it: Verify the material brand, SAP percentage, and request third-party absorption tests before production.
Some suppliers provide only samples without proper test documentation. Without verified TDS or lab results, performance claims cannot be trusted.
How to avoid it: Request complete test reports, including absorption, rewet, acquisition time, and tensile strength.
Factories without strict QC steps may produce inconsistent products or high defect rates.
How to avoid it: Check their QC process, batch traceability, and inspection standards.
Diapers must meet local chemical safety and hygiene standards, such as OEKO-TEX, REACH, or CPSIA. Non-compliance can lead to market recalls.
How to avoid it: Ask for certificates and third-party verification.
Errors in packaging, size, elastic design, or graphics often occur due to unclear communication.
How to avoid it: Provide detailed specifications and confirm each step before production.
Even a high-quality supplier can fail if raw materials are unstable or lead times are unrealistic.
How to avoid it: Review their production capacity, sourcing reliability, and shipping track record.
Conclusion
By proactively identifying these six hidden risks, purchasing managers can avoid common mistakes, ensure product quality, and maintain smooth OEM/ODM operations. Choosing a reliable partner with transparent processes, certified materials, and proven QC is the key to successful diaper projects.
