What Breaks Glass in Transit

Glass and other fragile goods are damaged in transit by impact, vibration and stacking pressure, and the paper often used to pad them fails when it gets damp. Preventing damage comes down to cushioning that absorbs shock, pallets stacked to the right height, packing kept dry, and careful handling when the container is stuffed and unloaded.

Four Causes of Breakage and How to Prevent Each

Impact and Shock
The risk

Glass can fracture under even mild force, or from vibration repeated over a long voyage. Corners, rims and stems are the most fragile points.

How to prevent it
  • Double-box fragile SKUs
  • Cushion with foam sheets, bubble wrap or honeycomb padding
  • Put spacers between items
  • Leave no loose gaps inside the carton
  • Give corners, rims and stems the most protection
Vibration and Hidden Micro-Cracks
The risk

Cartons can arrive looking intact while the goods inside have micro-cracks from a long transit.

How to prevent it
  • Add cushioning layers that absorb vibration
  • Don't under-fill or over-fill cartons
  • Use foam inserts for premium items
  • Watch ceramic dinnerware: it often chips from vibration inside the carton, not from an outside knock
Stacking Pressure and Pallet Stability
The risk

Glass is heavy. Too much weight stacked on top can crush the cartons at the bottom of a pallet.

How to prevent it
  • Use sturdy cartons with reinforced bases
  • Limit pallet height to what the cartons can bear
  • Add corner boards for vertical strength
  • Shrink-wrap and strap each pallet for stability
Moisture and Mold in Paper Padding
The risk

Glass is often packed with paper. Damp padding loses its protective strength and can grow mold and mildew.

How to prevent it
  • Add desiccant bags to pallets on long sea routes
  • Make sure the warehouse and the container are dry before loading
  • Shrink-wrap pallets
  • Replace any padding that has gotten wet

Documents for a Fragile Shipment

DocumentWhy It Matters
Commercial invoice States the product type, the HS code and any fragile-goods notes
Certificate of origin (COO) Confirms where the goods were made; customs in many countries require it
Packing list with carton count and weights Lets the receiving team plan a safe unload
Fragile-goods marking (internal requirement) Tells the warehouse, the container stuffing team and truckers to handle with care
No special trade certificates are normally needed unless the goods are high-value curated items.

Import Notes by Destination

United States
  • A certificate of origin is often needed
  • Fragile marking helps prevent rough handling when cargo is transloaded
European Union
  • A certificate of origin is frequently requested
  • No special import restrictions on general glassware
Middle East
  • A certificate of origin is widely required
  • Packaging quality is often checked on consumer shipments

FCL, LCL or Air for Fragile Goods

ModeBest When
FCL (full container) You are shipping a large fragile consignment
Palletized LCL (shared container) The order is small; safer than loose cartons in a shared container
Air freight The goods are high-value or urgent
Whatever the mode: load fragile cartons on top where possible, label them "Fragile / Handle with Care / Do Not Stack", and use rubber mats at the warehouse loading area if available. The aim is to avoid shock, pressure and vibration at every stage.

Fragile Cargo FAQs

Is palletization required for glassware?

Not required, but strongly recommended: loose cartons raise the risk of breakage.

Should glassware be double-boxed?

Yes, for premium products and thin-walled glass. Double boxing reduces shock damage.

What causes most breakage in fragile cargo?

Three things: shock to the corners, vibration over a long transit, and too much weight stacked on top.

Do fragile items need cargo insurance?

It is advisable, because the risk of physical damage is higher than for most cargo. See our cargo insurance service.

Can fragile goods ship LCL?

Yes, but only palletized. Avoid shipping loose cartons in a shared container. See how LCL shipping works.
