Quick answer. Landed cost is what one unit costs by the time it reaches you: the price you paid the supplier, plus duty, freight, insurance, broker fees and CBP fees, divided by the units. Low-value shipments no longer enter duty-free, so even a small order needs the duty in the math. For example, 500 units at $8.00 with a 10% duty rate, $680 freight and insurance, a $175 broker fee and the CBP fees land at about $10.59 a unit; at a $20 price that's a 47% margin.

What changed for low-value imports
Section 321 of the Tariff Act (19 U.S.C. 1321(a)(2)(C)) let goods worth $800 or less, imported by one person on one day, enter free of duty. That treatment is suspended:
- All modes except mail: CBP's interim final rule suspended the exemption indefinitely, effective June 24, 2026. These shipments now need a formal or informal entry; release from the manifest and the Entry Type 86 test are no longer available.
- Mail: a companion rule, effective July 24, 2026, did the same for the international postal network and created a postal informal entry for mail shipments of $2,500 or less. The owner, purchaser or a licensed broker files the data and pays through Pay.gov by the 7th day of the following month. Some goods must enter formally; for certain categories CBP moved that compliance date to January 20, 2027.
- Before the rules: Executive Order 14388 (February 20, 2026) continued an earlier suspension, from Executive Order 14324 of July 30, 2025, for goods entered from February 24, 2026.
- Not affected: bona fide gifts and personal or household articles that travel with a returning traveler.
- Ahead: CBP's rule notes that Public Law 119-21 (section 70531(b)) ends the statutory exemption effective July 1, 2027. A separate CBP proposed rule on low-value shipments (October 2026) would change informal entries further; it is a proposal, not in effect.
How the duty is figured
- Classify the product in the Harmonized Tariff Schedule. CBP's duty rate page points out that classification turns on details such as material, construction and origin, and that CBP has the final say.
- Read the rate column. Column 1 General covers most countries; Column 1 Special can be lower for free trade agreement and preference partners; Column 2 applies to North Korea, Cuba, Russia and Belarus (USITC).
- Add any additional duties listed in HTSUS Chapter 99, such as Section 232 or Section 301 duties, for your product and country.
- Apply the rates to the customs value. That's normally the transaction value, the price paid for the goods; separately billed international freight and insurance are left out (19 CFR 152.103).
Entry types and CBP fees
MPF amounts apply October 1, 2026 to September 30, 2027 (CBP Dec. 26-14). Your broker's invoice shows the fees actually charged; use those when you have them.

Common questions
Is there still a duty-free limit of $800 for imports?
Not for most commercial shipments. CBP suspended the de minimis exemption indefinitely for shipments arriving by every mode other than mail as of June 24, 2026, and for mail shipments as of July 24, 2026. Bona fide gifts and articles that travel with a returning traveler aren't affected by those rules.
Do I pay duty on shipping costs?
Usually not. The customs value of most purchases is the transaction value, the price paid for the goods. International freight and insurance are left out when they're billed separately from the goods (19 CFR 152.103). That's how this calculator works; your broker can tell you if your terms of sale change it.
Where do I find my duty rate?
Look up your product's classification in the Harmonized Tariff Schedule at hts.usitc.gov, read the General or Special rate for your country of origin, and check the line's footnotes and Chapter 99 for additional duties. Only CBP's classification is final, so confirm with a customs broker or ask CBP for a binding ruling.
What is the merchandise processing fee?
A CBP user fee on most entries. From October 1, 2026, a formal entry pays 0.3464% of the value, at least $34.58 and at most $670.86; an informal entry filed electronically and not prepared by CBP pays $2.77. The amounts change every October 1.
When do I need a formal entry?
Informal entry covers shipments valued at $2,500 or less (19 CFR 143.21), with exceptions such as certain Chapter 99 goods over $250. Shipments above $2,500 generally need a formal entry, and CBP can require one for others.
How do mail shipments work now?
Mail shipments of $2,500 or less can use CBP's postal informal entry: the owner, purchaser or their licensed broker files the shipment data and pays through Pay.gov by the 7th day of the month after arrival, with a basic importation bond. Duty is no longer collected on delivery.
