Duty-free cargo does not necessarily imply freedom from associated costs and fees. Cargo transportation generally requires a commercial invoice, packing lists, customs declaration and bills of lading.

Ocean freight requires thorough information about the cargo contents, purchase prices, origin and destination. When maritime cargo passes through US ports at least once during their journey, they are liable to attract a harbor maintenance fee and merchandise processing fee on domestic shipments and imports alike.

What Is Harbor Maintenance Fee?

The US Customs and Border Protection levies the harbor maintenance fee for all maritime imports. Also known as ‘user fees’, they are tax charges officially levied on all imports irrespective of the means of transportation unless they arrive from Canadian ports.

The Water Resource Act of 1986 states that this tax could partly fund all harbor, inland water transport and flood control projects. All imports, domestic shipments, foreign trade zone shipments and passengers on cruise ships attract the HMF.

Thus, the US federal government charges HMF to bring foreign goods into the country and its calculation is provided in the next section.

How Is Harbor Maintenance Fee Calculated?

All shipments arriving in the US are liable to pay a Harbor Maintenance Fee according to the Water Resources Development Act. The fee is applicable for all imports irrespective of customs and other duties already paid.

The harbor maintenance fee rate is calculated as a percentage (0.125%) of the gross cargo value.

HMF = 0.125% of Cargo value So, for a cargo value of $200,000, CBP charges HMF = .125% of $200,000 = $250. Unlike the Merchandise Processing Fee, HMFs do not have a minimum or maximum charge.

The US Customs and Border Protection state that cargo importers are liable to pay the harbor maintenance fee. Importers sign a CBP Form 7501 to initiate the payment. Importers pay normal and customs clearance duties to release their cargo. Harbor maintenance fees are additional charges that importers pay for cargo. If importing into Foreign Trade Zones, they must pay HMF every quarter by signing CBP Form 349. The last days of March, June, September, and December mark the beginning of quarterly periods, and payments must be made within 31 days post quarter. The Harbor Maintenance Fund accepts HMF, which sponsors harbor maintenance projects and development in the US. Harbor maintenance fee payees must pay in cash or personal checks.
