If you’re importing goods into the U.S., you’ve probably come across the term harbor maintenance fee, or HMF, on your shipping invoices or customs paperwork.
It’s one of those things that doesn’t seem like a big deal until you realize it adds up quickly and needs to be accounted for in your landed costs.
Let’s break it down together.
Why Is the Harbor Maintenance Fee Charged?
Simply put, the harbor maintenance fee helps fund the upkeep of U.S. ports and harbors.
That includes dredging, repairs, and infrastructure upgrades so that ships can dock, load, and unload safely and efficiently.
Think of it as a port usage tax that helps maintain smooth operations.
HMF Meaning and How It Works
So, what’s the HMF meaning in real terms?
It’s a small percentage, typically 0.125%. charged on the value of imports coming into U.S. ports.
This fee applies whether the goods arrive by ship or are moved through ports by truck or rail under certain conditions.
If you’re using a freight forwarder or customs broker, this fee is often included in your total invoice. But it’s still important to understand it because it affects your bottom line.
Who Pays the HMF Fee?
The HMF fee is paid by the importer of record. That could be your business, or a third-party logistics partner handling your imports.
If you’re unsure, it’s worth asking your broker to confirm whether this fee is being filed and paid correctly on your behalf.
Does HMF Apply Everywhere?
The HMF USA scope applies to commercial cargo entering through coastal ports.
It does not apply to exports or cargo entering via air. If your goods land in a non-coastal port or arrive by plane, the harbor maintenance fee won’t be charged.
