About DutyChecker

DutyChecker answers one question: what will this international purchase actually cost me at the door? Not just the tariff — the whole stack: customs duty, CBP's Merchandise Processing Fee, and the brokerage fee your carrier charges to clear the parcel.

Why we built this

When the $800 de minimis exemption was suspended in 2025, millions of US shoppers suddenly started receiving customs bills on ordinary purchases — a £60 sweater from the UK, a ¥12,000 figure from Japan. Existing duty calculators were built for freight forwarders: they ask for HS codes most shoppers have never heard of, and they ignore the carrier brokerage fees that often exceed the duty itself.

DutyChecker speaks plain language. You pick "clothing" or "shoes"; we select a representative HTS product, apply the verified rules and show applicable government fees. Your courier or formal broker quote completes the landed-cost estimate.

How we source our data

• Tariff rates — USITC Harmonized Tariff Schedule, current HTS snapshot verified October 2, 2026
• Tariff overlays — Federal Register and CBP CSMS trade-remedy notices (IEEPA, Section 301)
• MPF — 19 CFR 24.23, FY2026/FY2027 schedules selected by entry date
• Carrier fees — verified USPS dutiable-parcel fee; other charges require a service-specific quote
• Exchange rates — ECB reference rates via frankfurter.app, refreshed daily

Every rate on this site carries a verification date, currently Oct 2026.

What we are not

We are not customs brokers, and this is not legal or customs advice. Estimates reflect representative HTS classifications; a customs officer's classification of your specific item controls what you actually pay.
