Landed cost ends at the port. Getting product to a customer or warehouse is a separate bill — and on small shipments it's often bigger than the duty.

What Goes Into Your Landed Cost

Most first-time importers get surprised by the gap between the product price and what they actually pay to get goods through US customs. The supplier invoice is just the starting point. Tariff duties, customs fees, freight, and insurance together can add 15% to 80% (or more) to your base cost.

Customs Duties

Duties are the biggest variable. They’re a percentage of declared value. Every import currently faces the Section 301 forced-labor tariff (10% or 12.5% by tier) — see tariffs today for the full rate stack. On top of that, your goods may face Section 232 (50% steel, aluminum, copper), Section 301 (7.5-100% Chinese-origin), and the MFN base rate. These stack — see the China rate breakdown for the 35% effective math on consumer electronics, or the EU import duty walkthrough for a $30,000 French wine shipment.

Merchandise Processing Fee (MPF)

CBP charges 0.3464% of customs value on formal entries, with an FY2026 minimum of $33.58 and a maximum of $651.50 (effective October 1, 2025). Informal entries at or under $2,500 pay a flat fee instead ($2.69, $8.06, or $12.09). Applies even to duty-free goods. Qualifying USMCA goods can be MPF-exempt — this calculator does not remove that exemption. See what the Merchandise Processing Fee is.

Harbor Maintenance Fee (HMF)

0.125% of declared value on ocean shipments. Funds harbor dredging and maintenance. Air freight is exempt. Applies even to duty-free goods.

Section 321 De Minimis (suspended)

The $800 Section 321 de minimis exemption has been suspended for all countries — China and Hong Kong since May 2, 2025, and all other countries since August 29, 2025 (continued by executive order in February 2026). Shipments of any value now owe applicable duties and require a customs entry, so the calculator no longer treats low-value imports as duty-free.

Freight and Insurance

Get current quotes from your forwarder. Ocean rates have been volatile since the April 2026 Strait of Hormuz disruption, with rerouted lanes adding 10-15 days of transit time and higher per-container rates.

Tips from the Trenches

Always use your actual transaction value (CBP uses the invoice price; undervaluing is a compliance risk). Check FTA eligibility — the rules of origin paperwork is often worth the MFN savings. If sourcing from China, model with and without Section 301 since classification drives applicability.

Marketplace sellers sending inventory to a fulfillment center should read Amazon FBA import duty and landed cost. Amazon’s referral and storage fees are not customs charges.

And if any share of what you import gets re-exported, returned, or destroyed, part of your landed cost is recoverable — run the duty drawback calculator to estimate the 99% duty refund you may be leaving unclaimed.

Frequently Asked Questions

What's the difference between this and the tariff calculator?
The US customs duty calculator looks up an HTS code and stacks 2026 duty layers, then adds the same estimated landed-cost lines (your freight, estimated MPF, ocean HMF). This page is the category-only version of that math — useful when you do not have an HTS code yet. Both totals are estimates, not a CBP invoice.
Does this include freight and insurance?
You type freight, insurance, and other fees yourself — those lines are your estimates, not a quote. They are added to the landed total. Duty stays on the product value unless you check the CIF box (only when freight is not broken out of the invoice). Ocean shipments can add an estimated 0.125% Harbor Maintenance Fee. Get current freight quotes from your forwarder.
Does the $800 de minimis still apply?
No. The Section 321 $800 de minimis exemption has been suspended for all countries — China and Hong Kong since May 2, 2025, and all other countries since August 29, 2025 (continued by executive order in February 2026). Shipments of any value now owe applicable duties, so the calculator no longer treats low-value imports as duty-free.
Did I overpay duties in 2025?
Likely yes. SCOTUS struck down IEEPA reciprocal tariffs in February 2026. If you paid the IEEPA layer between April 2025 and February 2026, you may be owed a refund. Use the Per-Entry Refund Estimator linked above to see how much.
