How US import costs add up
On a $10,000.00 ocean shipment with a 5% duty rate and a 10% additional duty, the importer pays $500.00 in duty, $1,000.00 in additional duty, a $34.64 Merchandise Processing Fee and a $12.50 Harbor Maintenance Fee: $1,547.14 before freight and the broker.
Duty is charged on the customs value, normally the price paid to the supplier, not including international freight and insurance. Freight still belongs in your landed cost, because it is part of what each unit costs you to get onto a shelf.

The end of the $800 de minimis rule
Until August 2025, shipments worth $800 or less could enter the US duty-free, which is how many small cross-border sellers shipped orders direct to customers. That treatment has been suspended for all countries since 29 August 2025, the suspension has been continued in 2026, and the law that created it ends on 1 July 2027. Direct-to-consumer shipments from abroad now pay duties and fees, which shifts the maths toward importing in bulk into US stock or a fulfilment centre.

Frequently asked questions
How is US import duty calculated?
Duty is a percentage of the customs value of the goods, which is usually the price paid to the seller, excluding international freight and insurance. The rate comes from the product's 10-digit HTS code, plus any additional duties that apply to the country of origin. A $10,000.00 shipment at 5% duty owes $500.00; with a further 10% additional duty, $1,500.00.
How do I find the duty rate for my product?
Classify the product under the Harmonized Tariff Schedule at hts.usitc.gov. The "General" column is the normal rate; "Special" rates apply under trade agreements; chapter 99 lists additional duties such as Section 301 and Section 232. A customs broker or a binding ruling from CBP settles uncertain classifications.
What is the Merchandise Processing Fee?
A CBP fee on formal entries (generally goods valued over $2,500.00) of 0.3464% of the value, with a minimum of $34.58 and maximum of $670.86 per entry for fiscal year 2027 (from 1 October 2026). Informal entries pay a smaller flat fee.
What is the Harbor Maintenance Fee?
0.125% of the value of goods arriving by sea at a US port. Air and land shipments do not pay it.
Is the $800 de minimis exemption still available?
No. Duty-free de minimis treatment for shipments valued at $800 or less was suspended for all countries from 29 August 2025, and the suspension has been continued since; the statutory exemption ends on 1 July 2027. Low-value shipments now go through formal or informal entry and pay duties and fees.
What is landed cost?
Everything it costs to get a product into your warehouse: the price paid to the supplier, freight and insurance, duties, CBP fees, customs broker fees and delivery from the port. Use it, not the supplier price, as your cost when you set prices and margins.
