Used pallets in Frederick, MD
Frederick is where Maryland keeps its distribution centers. Costco’s wholesale and e-commerce center and Aldi’s distribution center are both among the county’s largest employers, and the highways that meet here make it a natural place to move freight.
The big docks
The county’s major employers for 2023 and 2024 include Costco’s wholesale distribution and e-commerce center with 640 employees, the Aldi distribution center with 596, STULZ Air Technology Systems with 529 and AstraZeneca’s biotech manufacturing with 725. Lonza and Thermo Fisher are also in the county. Wholesale distribution, grocery distribution, HVAC manufacturing and biomanufacturing are the industries that matter for pallets.
The county had 226 manufacturing establishments employing 5,642 people in 2024, and a dock on that scale is where a regular pickup makes sense. A distribution center that turns over thousands of 48x40 pallets a week is a different conversation from an alley behind a bar; it is a dock program.
Highways and rail
Frederick County is served by I-70, I-270, U.S. 15, U.S. 40 and U.S. 340, by CSX and Maryland Midland rail, and by more than 70 local and long-distance trucking establishments. That is a lot of freight movement for a county of its size. From Frederick to the District line is a longer haul than from Prince George’s, so loads need to be big enough to justify the run.

What we ask about a Frederick load
Whether it is a one-off or a weekly flow; the haul is long enough that the second changes the plan. Whether the pallets are sorted; a distribution center’s receiving dock often is. Whether they are a standard size. We want a count and a grade, and we want to know how many trailers a month the dock fills with empties.
What each big site implies
| Site | Employees (2023–2024) | Pallet picture |
|---|---|---|
| Costco wholesale distribution and e-commerce center | 640 | High-volume 48x40; mixed vendors inbound |
| Aldi distribution center | 596 | Grocery freight; steady weekly flow |
| STULZ Air Technology Systems | 529 | Commercial air conditioners; finished units, so a stronger pallet is likely |
| AstraZeneca biomanufacturing | 725 | Controlled; clean and specified |
| Lonza and Thermo Fisher | In the county note | Biomanufacturing; small recurring batches |

Trucking county
More than 70 local and long-distance trucking establishments operate in the county, which is the practical reason Frederick works as a pallet market. Trucks that deliver here often leave empty, and a trailer going back toward the District is the cheapest way to move a load of sorted pallets in either direction.
It also means a buyer in Frederick is rarely short of a way to take pallets away. What is scarce is a seller with a sorted, consistent stream, and a distribution center that keeps its empties in order is the best customer the county has.
Questions we ask a Frederick dock
- How many trailers of empties a month? The answer decides whether a standing arrangement makes sense.
- Are they sorted? By size, by grade, by whether they are pooled.
- Is there a yard? A place to stage the pile for a driver.
- What is the receiving schedule? Say when the dock is slow.
