Our 3PL in Niles, IL is the whole operation
Some companies have a headquarters and a warehouse and a satellite something. We have a building. Our 3PL in Niles, IL is the only place your inventory will ever go: 5673 W Howard St, Niles, IL 60714, just outside Chicago's northwest city limits.
That makes this page a little different from our other location pages. The Chicago page talks about local drop-offs, and the Illinois page covers running an account remotely. This one is about the place itself. What happens when a truck backs in, where your units go, how they leave.
If you like to know how the sausage gets made before you hand over inventory, read on.
A day inside the Niles 3PL warehouse
No two days look exactly alike (a floor-loaded container on a Tuesday changes everyone's plans), but the flow through the building is pretty consistent. Inventory comes in one side, gets worked, waits if it needs to, and goes out on a carrier.
- 01
Receiving
Parcels, pallets and containers arrive and get checked against the work order and inbound instructions. Counts, condition and labels are confirmed here.
- 02
Prep stations
Units get labeled, bagged, wrapped, bundled or inspected, depending on what the work order says. This is where most of the hands-on work happens.
- 03
Storage
Anything not shipping right away goes into bins, onto pallets or into cubic-foot storage for oversize items.
- 04
Outbound staging
Finished shipments and packed orders are staged and sorted by carrier, so pickups go quickly and nothing ends up on the wrong truck.
- 05
Carrier pickup
Scheduled pickups run Monday through Saturday for GOFO, UPS, USPS and FedEx. Freight for pallets is arranged per shipment.
Approximately 1,000+ parcels move through that flow on a typical day. That number matters for one reason: the team is used to volume, so your 200-unit FBA shipment isn't a big event that throws the whole floor off.
Receiving: where most problems get caught
Here's the thing nobody tells you about warehouses. The work itself (labeling, bagging, packing) is rarely where things go wrong. It's receiving. A carton with no name on it. Twelve SKUs in one box with no packing list. A pallet that's 80 inches tall and leaning.
So we're strict about it, in a friendly way. Every inbound is expected to have inbound instructions behind it. Standard cartons are received at $1.00 each and pallets at $10.00. Anything unscheduled or messy (missing ASN, mixed SKUs, damaged freight, no labels) gets handled as problem receiving at hourly rates, and you hear about it. The full rundown is on our inbound receiving and inventory control page.
Got containers? We unload those here too, from $350 for a 20-foot palletized container. See forwarding and cross-docking.
The Niles prep center side of the building
Most of our prep work is for marketplaces, and most of that is Amazon. That's the Niles FBA prep you'd expect: FNSKU labels at $0.35-$0.40 a unit (you supply the label file digitally), poly bags from $0.30, bubble wrap from $0.60, and carton builds at $5 a carton plus materials. Wholesale prep starts at $0.70 a unit. Details live on the Amazon FBA prep page.
24-hour FBA prep is available for qualifying work orders. "Qualifying" isn't a weasel word, by the way. It depends on how many units, how many SKUs and how much each one needs. The team tells you before you ship.
The same prep stations also handle Walmart WFS prep, kitting and bundling, and inspection and QC. The overview of all of it is on the marketplace prep page. And just so it's said plainly: we support these marketplace workflows, we're not partners or official providers for any of them, and you're responsible for following each platform's current prep rules.
Niles warehouse storage: bins, pallets and containers
Storage is the quiet part of the building. Bins of small items that ship a few at a time. Pallets of slower stock waiting for the next FBA restock. Oversize stuff that doesn't fit either.
- Standard box or bin storage: $4-$6 a month, with the size limit confirmed in your quote.
- Standard pallet up to 72 inches: $35 a month, dropping to $32 at 25-99 pallets and $28-$30 at 100+.
- Oversize items by the cubic foot: $0.55-$0.75 per cubic foot a month.
- Container storage: $600 a month for a 20-footer, $800 for a 40-footer.
Stock that sits a long time costs more (1.25x base after 90 days, 1.50x after 180). That's on purpose. The full picture is on the warehouse storage page and the storage and movement overview.
The Niles fulfillment center and its outbound dock
Orders for Shopify stores, eBay, Etsy, TikTok Shop and seller-fulfilled Amazon and Walmart all get picked and packed here, then staged by carrier. Pickups run Monday through Saturday for GOFO, UPS, USPS and FedEx. Saturday pickups are a nice bonus for sellers whose weekend orders used to wait until Monday.
Pick and pack starts at $2.75 for the first item per order at 1-250 orders a month, and same-day fulfillment is available for qualifying orders. Find the per-channel detail under fulfillment and dispatch, or start with FBM and DTC fulfillment.
Returns come back to the same building, which is handy. They're opened, checked and either restocked, refurbished or disposed of under recovery and projects. Basic return receive and scan is $3.50 a unit.
Who the building is really set up for
Since everything happens in one place, the mix of work on the floor on any given day is pretty wide. A pallet of private-label kitchen goods getting FNSKU labels for Amazon. A few hundred TikTok Shop orders getting packed after a video took off. A container of imported home goods being sorted by SKU. A bin of eBay returns waiting to be graded.
That variety is kind of the point. Plenty of sellers start with one service and later add a second or third without changing warehouses, because the same team that receives the inventory can also prep it, store it, ship it or take it back. Nobody has to hand your account off to another facility.
Who isn't a fit? Anyone shipping hazardous materials, chemicals, canned soda, or counterfeit, stolen or unsafe products. Liquids over 2 lb need written approval first, and dietary supplements need invoices from a U.S.-based manufacturer or authorized U.S. distributor (supplements sourced straight from overseas suppliers aren't accepted). If that's you, it's better to hear it now.
Before your first shipment to our 3PL in Niles, IL
A few things need to happen before anything rolls up to the dock. None of them are complicated, but skipping one is how inventory ends up sitting in a corner with a question mark on it.
First, onboarding. We ask for verifiable U.S. company information: your legal company name, business address, EIN or registration, an authorized U.S.-based signer and a valid government photo ID. Second, a work order that says what's coming and what to do with it. Third, inbound instructions from the team, so receiving can match your cartons to your account.
Also worth knowing: shipping labels you supply must be legally purchased and valid, and we may ask for proof of where your inventory came from (invoices, receipts or POs). That's standard for us. It protects you as much as it protects the warehouse.
Insurance coverage, and what it doesn't cover
We maintain up to $5 million in insurance coverage for qualifying warehouse operations. That's a real number, and a lot of sellers are glad to hear it.
But read the conditions, because they matter. Coverage is subject to policy terms, limits, exclusions and claim eligibility. It isn't automatic for every item, so confirm with the team before you ship anything high-value. And the warehouse isn't responsible for carrier delays or damage once a package leaves on a pickup, for customs issues, or for marketplace suspensions. The terms page spells all of this out.
We'd rather say this now than have a conversation about it after something breaks. Honestly, it's the conversation nobody enjoys.
Visiting the warehouse in Niles
Hours are Monday through Saturday, 10:00 AM to 4:00 PM Central. Sundays we're closed.
If you want to visit or drop off inventory, contact the team first: 773-829-5355, info@treasureworldprep.com, or WhatsApp. That way someone's free to walk you around instead of waving at you from a pallet jack. Inventory drop-offs still need finished onboarding and a confirmed work order.
