What packaging specs reduce Amazon FBA leakage returns for body wash and body oil?

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.

• For Amazon FBA, the most effective leakage-reduction specs are: (1) induction seal on every bottle (foil seal matched to PET/HDPE or glass), (2) closure with a PE foam liner or EPE gasket, (3) tamper-evident shrink band, and (4) cap/pump lock (disc-top or lockable pump for body wash; tight screw cap for body oil).
• Set and verify application torque and re-torque after 24 hours; leave controlled headspace to avoid pressure weeping during transit.
• On the pack-out side, we recommend individual unit polybagging for liquids (with appropriate warning), plus a snug inner fit (carton insert or bubble sleeve) to prevent cap side-load.
• Avoid acrylic unless you need the look; it typically adds lead time and can crack under impact.
• Operationally, our MOQ is typically 1,000-3,000 units depending on packaging and formula complexity (kits are usually higher).
• After sample confirmation, mass production is commonly 10-20 working days, while packaging ordering can take 10-30 working days (e.g., glass bottles ~15 days; acrylic up to ~30 days).
• We can support documentation and arrange product send-out testing/report tracking; we also provide barcode and packaging design support.
