3PL vs Freight Forwarder (and Customs Broker): Who Does What When You Import

Most importing brands need all three jobs done, but not always three companies. Some forwarders run warehouses, some 3PLs book ocean freight, and some forwarders are licensed customs brokers too. Know which job each company does for you, because the handoffs between them, at the port and the warehouse dock, are where delays turn into charges.

We checked how much import work the 3PLs on Fulfill.com take on themselves. Of the 2,701 3PLs with a profile on Fulfill.com, 771 list at least one port handoff service (port drayage, container devanning or transloading), and 411 list at least one of ocean freight, air freight or end-to-end import. Providers list their own services, so read these counts as floors.

Freight forwarder vs customs broker vs 3PL at a glance

What a freight forwarder does

A freight forwarder sells you a route, not a vehicle. It usually owns no ships or planes. It books space with ocean and air carriers, combines smaller loads into shared containers, prepares the shipping documents and tracks the cargo until it lands. A typical forwarder handles:

• ocean space (a full container or a share of one) or air space;
• pickup at your supplier and the export paperwork at origin;
• the bill of lading or air waybill, and cargo insurance if you ask;
• tracking, and the arrival notice when the goods land;
• often the Importer Security Filing and the customs entry, through a licensed broker.

A US company that acts as an ocean freight forwarder or a non-vessel-operating common carrier needs a license from the Federal Maritime Commission (46 CFR 515.3). An NVOCC is a carrier that does not operate the ships it uses (46 CFR 515.2). Ask any US forwarder that handles your ocean freight for its FMC license number.

Who hires the forwarder depends on the Incoterms in your purchase order, so ask your supplier which one applies before anyone books a container. If you import a few pallets at a time, ask for LCL (less than container load) quotes: the forwarder ships your cartons in a container shared with other importers.

What a customs broker does

A customs broker is licensed by US Customs and Border Protection (CBP) to transact customs business for other people (19 CFR 111.2). For an importing brand, that comes down to four jobs:

• Classification. It finds each product's code in the Harmonized Tariff Schedule, which sets the duty rate.
• The entry. It files the entry and the entry summary with CBP.
• Payment. It pays duties, taxes and fees for you, then bills you.
• The bond. CBP will not release a formal entry without a single-entry or continuous customs bond on file (19 CFR 142.4), and the broker usually arranges it.

Ocean cargo has a deadline before the ship leaves: the Importer Security Filing must reach CBP no later than 24 hours before the goods are loaded aboard the vessel at the foreign port (19 CFR 149.2). The importer or its agent, often the broker or forwarder, files it, so they need your supplier's details early.

You do not have to use a broker: an importer can file its own entries without a license (19 CFR 111.2). Either way, the importer of record, usually your company, must use reasonable care in what the entry declares, whether it files itself or through an agent it authorizes in writing (19 U.S.C. 1484). Low-value shipments used to enter without duty under the de minimis exemption, Section 321. That exemption is suspended; our Section 321 guide covers what importers do now.

What a 3PL does for an importer

A 3PL (third-party logistics provider) takes over at its warehouse door: receiving, storage, picking, packing, shipping orders and returns. For an importer, the useful 3PLs also handle the awkward part of arrival, like unloading containers packed with loose cartons and booking the truck from the port. Here is how many 3PLs on Fulfill.com list each import service.

Two numbers stand out. Only 66 list transloading, the move that sends an ocean container back to the carrier fast. And only 87 list both port drayage and container devanning, so do not assume the company that pulls your container from the port also unloads it. Plan that handoff on purpose.

On certifications, 269 list a bonded warehouse, 85 list C-TPAT and 16 list a foreign-trade zone. Our guide to bonded warehouses and foreign-trade zones explains how the two differ.

The handoff: from the port to the 3PL's dock

This is where the three roles meet, and where delays start to cost money. Here is the order of events for an ocean container.

1. Arrival notice. The forwarder or carrier tells you when the ship arrives and which terminal holds the container.
2. Release. Your broker files the entry. The container cannot leave the terminal until CBP releases the goods and the carrier releases the container, usually once freight charges are paid.
3. Pickup. A drayage carrier collects the container on a chassis and trucks it to the warehouse or to a transload site.
4. The clock. The terminal and the carrier allow a set number of days, called free time. Past it, demurrage and detention start: charges for using terminal space or the carrier's container, apart from the freight (46 CFR 541.3). In everyday use, demurrage means the container sat at the terminal too long, and detention means the carrier's container was kept out too long.
5. Unloading. The 3PL devans the container. Pallets come off with a forklift; loose cartons come off by hand, which takes longer and usually costs more. The 3PL checks the cartons against your packing list before the stock goes live.
6. Empty return. The empty goes back where the carrier says, which stops the detention clock.

Near the big ports, many importers transload instead: the cartons move into a 53-foot domestic trailer near the port, the container goes straight back, and the trailer goes on to one warehouse or several.

Who books the truck? Either the forwarder quotes door delivery and books the drayage, the 3PL runs or contracts its own, or you hire a drayage carrier yourself. Whichever you pick, put one company's name next to "last free day" in writing.

Where your containers land shapes which 3PL makes sense. Here is how many of the 3PLs that list port drayage have a warehouse in eight of the major port states, plus Illinois for Chicago's rail ramps.

A 3PL counts once per state where its profile lists a warehouse. Not every profile lists its warehouse addresses, so these are floors too.

When one company does both

Plenty of companies blur the line. Of the 2,701 3PLs on Fulfill.com, 258 list end-to-end import, and 207 list port drayage alongside ocean freight, air freight or end-to-end import. From the other side, large forwarders run their own warehouses. Combined providers come in three common shapes:

• A global forwarder with warehouses. Kuehne+Nagel lists sea and air freight, customs clearance, warehousing and ecommerce fulfillment among its services.
• A regional forwarder that also fulfills. KCE Logistics, based in Miami, describes itself as an international freight forwarding, warehousing and fulfillment provider.
• A 3PL that runs its own drayage. First To Final Logistics, an Atlanta 3PL, lists drayage, cross-docking, warehousing, order fulfillment and final-mile delivery: "port to porch", in its words.

One provider means one contract, one invoice and no argument over whose fault a delay was. Separate specialists let you shop each leg and switch forwarders without moving inventory. If a company says it handles imports end to end, ask which parts it does itself, which it subcontracts, and under whose license the customs entry is filed.

How the costs split

Each role bills its own lines. We do not print rates, because they move with the lane, the season and the tariff on your goods; use this table to check that your quotes miss nothing.

Two habits prevent surprises: ask every quote to list what it excludes, and add duties, drayage and receiving to your landed cost before you set prices.

Questions to ask before you hire each one

Freight forwarder

• Are you an FMC-licensed forwarder or NVOCC, and what is the license number?
• Who files my customs entry and Importer Security Filing, and under whose broker license?
• Is door delivery included, and who books the drayage?
• Who pays if a container misses its last free day?

Customs broker

• Will you review my product classifications before the first entry?
• Should I use a single-entry bond or a continuous bond at my volume?
• Do you advance duties, or do I pay them before you file?
• Who do I call the day a shipment is held?

3PL

• Do you unload floor-loaded containers, and how do you price it?
• Do you run or contract port drayage, and from which port?
• How long from container arrival until my stock is available to sell?
• What do you need before arrival: a packing list, an advance ship notice, a delivery appointment?

When you get to signing, our 3PL contract guide walks through the clauses that matter.

3PL vs freight forwarder FAQ

Is a freight forwarder a 3PL?

Broadly, yes: it is a third party running part of your logistics. In ecommerce, though, "3PL" usually means a fulfillment warehouse, and most forwarders do not store and ship your orders. A company that coordinates several providers for you is closer to a 4PL.

Can a freight forwarder clear customs for me?

Only through a licensed customs broker. Some forwarders hold a CBP broker license themselves; others hand your entry to a broker they work with. Either way, ask whose license the entry is filed under.

Do I need a customs broker if I already have a freight forwarder?

You need someone licensed to file your entry, unless you file it yourself as the importer. If your forwarder's quote includes customs clearance, its broker files for you. Check, because clearance is often a separate line.

Does a 3PL near the port replace a freight forwarder?

No. A port-side 3PL can handle drayage, unloading and storage, but someone still has to book the international freight and file the customs entry. Some 3PLs also arrange the freight: 137 on Fulfill.com list ocean freight.

Who pays demurrage and detention?

The terminal or ocean carrier bills them, usually to the importer or to the forwarder that booked the move, which passes them on. Your contracts decide who absorbs them, so name in writing who owns the pickup and the empty return.

What is the difference between a freight forwarder and a freight broker?

A freight forwarder manages international shipments, including the documents and often customs. A freight broker matches your load with a trucking company, usually within one country, and handles no customs or storage.

Find a 3PL that handles imports

Start with where your containers land. Browse 3PLs that list port drayage or end-to-end import, or international fulfillment if you also ship orders across borders. Importing through Mexico? Our IMMEX program guide covers that route. Or tell us what you import and where it lands, and we will match you with 3PLs that fit.

How we counted. Counts cover 3PLs with an active profile on Fulfill.com on October 24, 2026, from the services, certifications and warehouse addresses each lists on its profile. Each count is a floor, and our specialty directory pages count by directory tag, so their totals can differ. Rules cited were read from the eCFR and the US Code the same day.
