Freight Class for Glass
Glass freight class commonly ranges from Class 85 to Class 250 in the examples below.
Dense glass-sheet crate
Class 85
Window and mirror crate
Class 125
Large light panel rack
Class 250
These are density-based examples. Your final estimate depends on the finished packaged dimensions, total weight, stackability, fragility, value, and handling requirements for the glass shipment.

Glass shipment comparison
Glass Freight Class by Shipment Type
Glass shipments may be dense by material weight but still occupy substantial protected cube because of A-frames, crates, edge clearances, separators, and no-top-load requirements. Sheet size, thickness, orientation, tempering, lamination, exposed edges, and rack stability materially affect handling.
| Glass shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| Crated glass sheets | Vertical crate with separators and edge blocking | Medium to high | Usually non-stackable | Keep sheets vertical and supported across the full edge. |
| Windows and insulated units | Partitioned crate or A-frame rack | Medium | Non-stackable | Protect frames, seals, corners, and glazing surfaces. |
| Mirrors and decorative glass | Foam-separated upright crate | Low to medium | Non-stackable | Shield finished faces and prevent vibration or flexing. |
| Oversized architectural panels | Engineered A-frame or specialty rack | Low | Non-stackable | Confirm rack stability, forklift spacing, and dedicated handling. |
glass shipping options
Choosing a Shipping Method for Glass
The right service depends on glass size, packaging, stackability, and handling needs.
| Glass shipment | Common shipping option |
|---|---|
| Small crated glass sheets | Crated LTL |
| Window or mirror crate | No-top-load LTL |
| Large A-frame glass rack | Specialized LTL |
| Oversized architectural glass panels | Dedicated or specialized glass transport |
Large, irregular, non-stackable, unusually valuable, or specially handled glass shipments may need carrier review before booking.

Glass Packaging
- Ship glass upright in a rigid crate, partitioned rack, or engineered A-frame.
- Use clean separators, edge blocks, corner guards, foam, and non-abrasive face protection.
- Secure the rack to the pallet or skid and prevent sheets from shifting, flexing, or contacting hardware.
Glass Stackability
- Glass crates and A-frames are normally non-stackable unless specifically engineered.
- Do not top-load exposed glass, window units, mirrors, or racks with uneven tops.
- Maintain upright orientation and keep forklift pressure away from glass faces and edges.
Glass Edge, Face, Seal, and Tip-Over Protection
- Prevent edge chips, face scratches, corner impact, flexing, vibration, and tip-over.
- Protect insulated-glass seals, window frames, mirror coatings, and laminated interlayers.
- Document orientation, rack condition, glass count, declared value, and visible damage before pickup.
Measure the fully crated or racked glass shipment
- Measure after the A-frame, crate, separators, edge blocks, guards, and pallet base are installed.
- Include rack angle, braces, handles, outriggers, pallet overhang, and protective clearance.
- Use the total packaged weight of the glass, frames, crate, rack, separators, and skid.
Before Requesting a Glass Freight Quote
- Measure the finished crate, A-frame, rack, or pallet containing the glass.
- Record the total packaged weight of the complete glass shipment, including the rack or crate.
- State that the glass package is upright and non-stackable unless the frame is rated otherwise.
- Include photos of edges, faces, separators, corners, seals, rack braces, and securement points.
- Confirm upright handling, forklift spacing, no-top-load, liftgate, and specialized glass-service requirements.
Calculate your actual shipment
Calculate Glass Freight Class
The calculator returns cubic feet, pounds per cubic foot, and a density-based freight class estimate for your glass shipment.
Freight classes shown on this page are density-based estimates for shipment planning. Actual classification may also depend on value, handling requirements, liability, stowability, dimensions, and other commodity-specific factors. Confirm the final freight class with your carrier, broker, or official NMFC resources before shipping.
