How to Ship Glass via LTL Freight
Complete guide to shipping plate glass, windows, mirrors, and glassware on pallets via LTL freight. Covers freight class, crating, accessorials, and the handling steps that keep dense, fragile glass from arriving cracked.
Quick reference
Recommended packaging
Glass moves in wood crates or steel A-frame racks, not on open pallets. Stand flat glass and mirrors on edge against the long side of the crate. Never lay large sheets flat where the center can flex and snap. Separate every pane with foam, cork, or rubber and cushion all four edges, then band the load so nothing can slide. Mark every face "Glass," "Fragile," and "This Side Up" and apply tilt indicators so a turned crate is obvious at delivery.
Accessorials you may need
These are the most common accessorial services for glass shipments. Declare them at booking time — carriers that discover them on arrival bill more and back-date to the invoice. With Warp, every accessorial below is already included in the per-pallet rate.

Shipping tips for glass
- Ship glass on edge in a crate or A-frame rack, never flat. Flat glass carries its load along the edge. Lay a large sheet down and the unsupported center flexes and cracks the first time the crate is set on a dock.
- Build the crate so the driver can never lay it down. A turned crate is the single most common cause of glass damage in LTL. Use tilt indicators and 'This Side Up' on every face so a tipped load is caught and noted before you sign.
- Crate tight, then weigh and measure the finished crate. Glass is dense, so a snug crate ships at a low class. Oversized crating adds void space, raises the class, and inflates your rate for no benefit.
- Photograph the loaded, sealed crate from every side before pickup. Time-stamped photos of intact glass and proper edge protection are the strongest evidence if a claim comes back questioning your packaging.
Common mistakes to avoid
Mistake 1: Carrier liability on glass is tiny relative to its value. Default coverage runs $0.10-2.00 per pound, so a $4,000 crate of mirrors weighing 600 lbs might get $600. Buy cargo insurance and declare full replacement value on the BOL.
Mistake 2: Liftgate and inside delivery on a 1,500-lb glass crate often trigger a two-man delivery fee on top, adding $100-250. Budget for all three if the destination has no dock and no forklift.
Mistake 3: Concealed damage on glass is brutal to claim after the fact. If you sign a clean delivery receipt and find a cracked pane later, you have waived most of your claim rights. Open the crate and inspect every pane before signing.
Why glass freight class sits lower than you'd expect
Glass is fragile, but for freight class purposes it is dense, and density is what sets the rate. Flat glass falls under NMFC 86700, which carriers rate by density rather than a flat published class. Crate a stack of plate glass or mirrors tight and it often lands at class 60-85 because it weighs a lot for the cubic space it fills. The class only climbs toward 100-150 when the load is bulky and light: framed mirrors with void space, single large panes in oversized crates, or glassware boxed with heavy cushioning. The lever is the crate. Pack tight, keep void space out, and weigh the finished crate, because the carrier classifies what it measures at pickup, not what your BOL claims. Declare a low class on a loosely crated load and the carrier reweighs, reclassifies, and bills the difference plus a fee.
Crating glass for LTL
An open pallet does not protect glass and no LTL carrier will treat it gently enough to matter. Glass needs a wood crate or a steel A-frame rack built so the panes stand on edge against the long wall, because flat glass carries its strength along the edge and snaps across an unsupported center. Separate every pane with foam, cork, or rubber so glass never touches glass, and cushion all four edges where impact concentrates. Band or strap the load so nothing shifts, then close the crate so the contents cannot be seen and the unit cannot be laid flat. Label every face 'Glass,' 'Fragile,' and 'This Side Up,' and add tilt indicators. The goal is a sealed unit that survives being loaded, unloaded, and reloaded at several terminals without a forklift operator ever guessing what is inside.
Choosing the right accessorials
Most glass goes to job sites, shops, and homes without a loading dock, and a heavy glass crate is exactly the freight you do not want a single driver wrestling alone. If the destination has no dock, you need liftgate delivery to lower the crate to ground level. If it has to go past the threshold, you need inside delivery. For a crate over roughly 150 pounds, or fragile panes that need careful handling, add two-man delivery so a second helper rides along. Glaziers, glass shops, and construction addresses also frequently read as limited-access locations, which carries its own fee. Add every accessorial you need on the BOL and the quote upfront. Discover them at the dock and the carrier charges them anyway at a higher rate, or refuses the delivery.
Glass shipping FAQ
What freight class is glass?
Glass typically ships between class 60 and class 150 depending on what it is and how it is crated. Flat glass such as plate, sheet, window, and mirror falls under NMFC 86700 and is rated by density, so a tightly crated, dense load often lands at class 60-85. Bulky, lower-density loads like framed mirrors or single oversized panes ship higher, around class 100-150. Glassware and tableware run similar. The exact class depends on the weight and dimensions measured at pickup.
How much does it cost to ship glass LTL?
LTL glass shipping costs $200-800 per crate depending on distance, freight class, weight, and accessorials. A dense, well-crated short-haul load with no extras is on the lower end. A heavy cross-country crate needing liftgate, inside, and two-man delivery is on the higher end. Crating and accessorial choices move the number more than mileage does.

What NMFC code is used for glass?
Flat glass: plate, sheet, window, float, and mirror, is classified under NMFC 86700, which carriers rate by density rather than a single fixed class. Glassware, drinking glasses, and tableware fall under separate items in the 88000 family, commonly around NMFC 88180. Because flat glass is density-based, the right approach is to crate it tight, measure and weigh the finished crate, and run the density to confirm your class before you book.
How do I avoid damage and claim denials when shipping glass?
Crate glass on edge in a wood crate or A-frame rack, separate every pane with foam or rubber, cushion all four edges, and seal the crate so it cannot be laid flat. Add tilt indicators and 'This Side Up' on every face. Photograph the sealed crate from all sides before pickup. At delivery, open and inspect every pane before signing, because a clean signature on a glass shipment waives most of your claim rights. Note any crack or chip directly on the delivery receipt.
Do I need liftgate or two-man delivery for glass?
Usually yes for both. Most glass deliveries go to shops, job sites, and homes without a loading dock, so you need liftgate delivery to bring the crate to ground level. A glass crate over about 150 pounds is too heavy and fragile for one driver to handle alone, so two-man delivery is common, and inside delivery is needed if the crate has to go past the door. Request these upfront. A failed first attempt on heavy glass is costly to reschedule.
