Quick Answer (for busy buyers)
Here’s the buyer-first summary. If your brand name is on the label, you usually act as the responsible person and must ensure the listing is submitted and kept current.
- Leakage prevention for baby wash and shampoo starts with packaging engineering.
- We use bottles from PP or HDPE with threaded caps, inner liners, and tamper-evident seals to create a tight seal.
- For Amazon FBA, we align with frustration-free packaging guidelines, adding corrugated boxes with cushioning to handle transit shocks.
- MOQ typically ranges from 500 to 1000 units per SKU, driven by custom tooling for caps and labels to balance cost.
- Sampling takes 2-3 weeks for prototypes, allowing feedback on fit and function before mass production.
- We conduct comprehensive testing including vacuum tests at simulated altitudes, vibration tests for shipping, and torque checks for cap consistency.
- Our QA process monitors fill temperature and viscosity to prevent expansion during air freight pressure changes.
- Documentation support includes FDA registration assistance, PIF (Product Information File) preparation, and COA (Certificate of Analysis) for US compliance.
- Lead time from production to shipping is 4-6 weeks, with pilot runs to validate leakage prevention under real conditions.
- Factory experience shows that humid seasons can cause label bubbling, so we use waterproof adhesives.
- We also recommend sea freight over air for pressure-sensitive products to minimize leakage risks.
Buyer outcome
A launch-ready compliance plan: inputs collected, roles assigned, and update cadence defined.
Most common blocker
Missing facility information + inconsistent ingredient/label snapshots across SKUs.
