✕ What triggers it

A cap seal is required, and was missing, when the item is a liquid, paste, gel, or cream and all of the following hold [2]:

  • Is 4.2 oz (125 mL) or more
  • Is non-hazmat
  • Is non-fragile
  • Has a lid type of twist / screw top, clip-on top, flip top, or hand pump
  • Does not have a secondary seal (see 6 for the pump exception)
✓ How to prevent it
  • Tighten the lid before applying the cap seal [1]
  • Twist / screw tops → apply the seal horizontally around the cap [1]
  • Flip / clip tops → apply vertically over the opening [1]
  • Pumps → apply vertically over the pump, attaching to the bottle on both sides [2]
  • Items with multiple openings → a separate seal for each [1]

4 Official exemptions

This is the only preparation type for which Amazon publishes an exemption. It splits by closure type [2]:

Item typeExempt when…
Non-pump (twist / screw / clip-on / flip top)It has a secondary seal (or double seal) — a cap seal is then not required
Pump / sprayA secondary seal alone is not enough. "Liquid pumps without a locking mechanism must have a cap seal even if they have a secondary seal." — exempt only when it has both a secondary seal and a locking mechanism

Cases where a cap seal is not the right prep at all (a different prep applies instead) [2]：

  • Hazmat / dangerous-good liquid → bagging or heat shrink required instead
  • Fragile → bubble wrap required instead (a cap seal may still also be needed if the wrap prevents breakage but not leakage)
  • Spray bottle without locking mechanism → bagging required instead
  • Fails a three-foot drop test → bagging or bubble wrap required instead
Internal note — not shown in product校验报告 P0-3 修正落点 —— CS PDF 写 "secondary seal AND locking mechanism — both conditions must be met"，把泵类的加严条件套到了全部商品。非泵类只需 secondary seal 即豁免。

5 Documents required for dispute

  1. Purchase order / shipping label [1]
  2. Photos of the product evidencing that it was properly packaged and barcoded and required no extra prep [1]
  3. Evidence of a secondary seal (and, for pumps, a locking mechanism) if claiming the exemption ⓘ Not published by Amazon
