These are density-based examples. Your final estimate depends on the finished packaged dimensions, total weight, stackability, fragility, value, and handling requirements for the plastic shipment.
Main class factor
Packaged density
Final dimensions and total weight
Assembly effect
Flat-packed ships denser
Assembled plastic occupy more space
Carrier review
Stackability and damage risk
Custom, fragile, or glass-front plastic

Plastic shipment comparison
Plastic Freight Class by Shipment Type
Plastic shipments vary from very dense resin pellets and sheet stock to low-density molded housings, empty containers, and foam products. The finished cube, nesting efficiency, wall thickness, surface finish, and stackability determine the shipment profile.
| Plastic shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| Plastic resin or pellets | Bags, gaylords, or drums | Very high | Usually stackable | Protect liners and prevent contamination. |
| Plastic sheets or panels | Flat bundles on pallets | High | Usually stackable | Protect faces and unsupported edges. |
| Molded plastic goods | Cartons, bins, or custom skids | Medium | Limited | Nest parts and prevent distortion. |
| Foam or hollow plastic items | Large cartons or wrapped bundles | Low | Limited | Avoid compression and top loading. |
plastic shipping options
Choosing a Shipping Method for Plastic
The right service depends on plastic size, packaging, stackability, and handling needs.
| Plastic shipment | Common shipping option |
|---|---|
| Bags or gaylords of resin | Standard LTL |
| Sheet and panel bundles | Standard or protected LTL |
| Molded plastic goods | LTL with packaging review |
| Bulky foam or hollow products | Volume LTL or dedicated service |
Large, irregular, non-stackable, unusually valuable, or specially handled plastic shipments may need carrier review before booking.

Plastic Packaging
- Use sealed bags, lined gaylords, cartons, bins, or wrapped sheet bundles appropriate to the resin or finished part.
- Separate polished, clear, painted, or textured surfaces with film, foam, paper, or dividers to prevent abrasion.
- Support large panels and molded parts so banding, heat, and uneven pallet pressure do not cause warping.
Plastic Stackability
- Dense resin bags and square cartons may stack when pallet patterns and compression strength are verified.
- Sheet bundles can accept top load only when fully supported and protected by rigid top boards.
- Treat hollow molded items, foam plastics, thin-wall parts, and irregular bundles as limited-stack or non-stackable.
Plastic Surface, Distortion, Contamination, and Heat Protection
- Prevent bag puncture, pellet contamination, sheet scratching, molded-part distortion, cracking, and stress whitening.
- Protect clear surfaces, thin walls, snap features, bosses, threads, and heat-sensitive shapes from pressure and impact.
- Document resin type, grade, color, dimensions, nesting orientation, finish requirements, and temperature limits.
Measure the fully packaged plastic shipment
- Measure after all bags, cartons, bins, panels, pallets, top boards, and protective films are installed.
- Include nested-part projections, sheet edge guards, gaylord bulges, foam overhang, and pallet caps.
- Use the total packaged weight of plastic, packaging, pallet, and securement.
Before Requesting a Plastic Freight Quote
- Measure the finished resin pallet, sheet bundle, molded-part carton group, or foam-product load.
- Record the total packaged weight of the complete plastic shipment, including bins, gaylords, and pallets.
- State whether the load is uniformly stackable or contains thin-wall, hollow, foam, or heat-sensitive parts requiring limited stack.
- Include photos of bag liners, sheet faces, molded features, carton interiors, top boards, and pallet securement.
- Confirm contamination control, temperature limits, clamp restrictions, liftgate, and appointment requirements.
Calculate your actual shipment
Calculate Plastic Freight Class
The calculator returns cubic feet, pounds per cubic foot, and a density-based freight class estimate for your plastic 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.
