Packaging That Survives Ocean Shipping for Glass Sliding Doors: Export Crates, Corner Guards & Fumigation Marks

Glass partition doors and glass wardrobe doors are among the most commonly sourced categories for overseas buyers, but also the highest in transit breakage. Whether they arrive intact comes down to packaging.

Export-grade glass packaging usually has four layers: a protective film on the glass surface; corner guards or edge protectors on all four corners; the whole pane wrapped in pearl cotton or EPE; finally packed into an export wooden crate with an ISPM 15 fumigation mark. The crate needs internal bracing so glass doesn't shift and knock during transit.

Before receiving, you can check these points:

1. Whether the wooden crate has an ISPM 15 fumigation mark.
2. Whether there's a separator between each glass pane.
3. Whether the crate has reinforcement bracing inside.
4. Whether the outer carton is marked fragile and with an up-arrow.
5. Whether the wooden crate is overly damp (damp crates warp and fall apart).

At the sampling stage, we recommend confirming the packaging plan together and asking the factory for the post-pack weight and dimensions — this directly affects your ocean-freight cost estimate. Full-container and LCL shipments have different strength requirements; LCL needs more reinforcement.

One simple check: ask the factory for a full video of the packaging process. Factories serious about export have ready footage; those sloppy with packing details tend to have more problems than just packaging once the goods reach port.
