Plastic Pellets Rail Shipping & Logistics: Rates, Railcars, Lanes

Polyethylene and polypropylene pellets from Gulf Coast crackers — light, free-flowing, and shipped in the biggest covered hoppers on the railroad.

Plastic pellets logistics by rail: what we do

Steel Wheel Logistics prices and coordinates plastic pellets carload moves nationwide — single cars and multi-car blocks — from routing and an indicative rate per car through car ordering, release and tracing to placement. Plastic pellets fill the car before they reach the weight limit (about 32–38 lb per cubic foot), topping out near 85–95 tons, so we spec the largest-cube jumbo covered hoppers the lane allows and check the load plan against the receiver's unloading setup. Typical end uses are injection molding, film, pipe, packaging — the feedstock of the plastics industry — we confirm the receiving track and unloading method before the first car is ordered. Where the plant has no spur, we set up transload at a bulk transload terminal near the receiver and price the rail-plus-truck move against straight truck, so the mode decision is made on numbers. Demurrage control is planned rather than reactive: manifest cars arrive bunched, so we set release rules with the receiver and watch free time car by car. Shippers who need equipment can use our railcar brokerage to source jumbo covered hoppers on lease or per trip.

What it's used for

Injection molding, film, pipe, packaging — the feedstock of the plastics industry.

How it moves

Gulf Coast petrochemical belt to converters nationwide; cars stage in massive storage-in-transit yards near Houston. Export resin transloads to the ports.

Indicative plastic pellets rail rates by lane

10 sample lanes from our rate model (priced in the model's plastic resin class, the same car family), spread from short to long haul. The rate is per car; the per-ton column divides it by 85 tons, the low end of a typical plastic pellets load. Open a lane for its route and per-leg breakdown.

By the numbers: state rail plan figures

How much of this commodity group moves by rail, as published in the states' own federally mandated rail plans:

Statewide rail tonnage

• Louisiana: 20.4 million tons of plastics and synthetic resins moved by rail in all directions in 2021 (Louisiana State Rail Plan 2024, p. 60).
• Georgia: 3.6 million tons of plastics and rubber moved by rail to, from and within the state in 2017 (Georgia State Rail Plan 2021, p. 15).

Single-direction figures

These count movement in one direction only — originated, inbound or outbound as each plan defines it — so they are not comparable with the statewide totals above.

• Wisconsin: 1.4 million tons of plastic materials or synthetic fibers terminated by rail in the state in 2019 (Wisconsin State Rail Plan 2026, p. 139).

Each figure is quoted from the cited state rail plan and reflects that plan's own data year, commodity grouping and methodology — figures from different plans are not directly comparable with each other. Some plans count traffic passing through the state and others exclude it; each line says which.

Common questions

Can plastic pellets (resin) be shipped by rail?

Yes. Plastic Pellets (Resin) moves regularly on the North American rail network in jumbo covered hoppers. Gulf Coast petrochemical belt to converters nationwide; cars stage in massive storage-in-transit yards near Houston.

How many tons of plastic pellets (resin) fit in a railcar?

A typical load is 85–95 net tons per car — the car fills up (cubes out) before it reaches its weight limit.

What railcar does plastic pellets (resin) move in?

Jumbo covered hopper (6,000+ cu ft). Because the commodity is light for its volume, shippers prefer the largest cubic capacity available.

What is the bulk density of plastic pellets (resin)?

Roughly 32–38 lb per cubic foot, depending on grade and condition.

Does Steel Wheel Logistics handle plastic pellets rail logistics?

Yes — we price and coordinate plastic pellets carload moves nationwide: routing and indicative rates per car in jumbo covered hoppers at 85–95 tons, car supply through our railcar brokerage, transload where the plant has no spur, and demurrage control. Call (601) 821-2199 or book a 30-minute setup call to walk through your lane.

Which U.S. port imports the most plastic pellets?

Los Angeles, CA led vessel imports of plastics and resin year to date through July 2026 at $5,660 million, followed by Newark, NJ and Savannah, GA.
