Customs fees from Japan to the US come in three parts: a 15 percent tariff on most goods, a merchandise processing fee of roughly a third of a percent, and, for anything arriving by ship, a harbor maintenance fee of 0.125 percent. The old $800 duty-free allowance no longer applies, so even small orders now carry these costs.
The 15 Percent Tariff and How It Works
Under the U.S.-Japan Agreement implemented in September 2025, nearly all Japanese imports carry a combined tariff rate of 15 percent.1The White House. Implementing the United States-Japan Agreement The rate replaced a 25 percent reciprocal tariff that had been in effect briefly earlier that summer, and it applies retroactively to goods entered for consumption on or after August 7, 2025.
The 15 percent figure is a ceiling, not an addition. Every product already has a “Column 1” duty rate in the Harmonized Tariff Schedule. If that existing rate is below 15 percent, the reciprocal tariff tops it up so the combined rate lands at exactly 15 percent. If the existing rate already meets or exceeds 15 percent, nothing extra is added. So a product with a 2.5 percent Column 1 rate picks up an additional 12.5 percent under the agreement, while one already at 20 percent pays nothing more.1The White House. Implementing the United States-Japan Agreement
To find your specific rate, look up your product’s 10-digit HTS code at hts.usitc.gov and check the Column 1 duty rate. If it’s under 15 percent, plan on 15 percent total. If it’s over, plan on the Column 1 rate.
Categories With Different Treatment
A few product groups sit outside the standard rule:
- Automobiles and auto parts fall under the same 15 percent combined cap, replacing the separate 25 percent Section 232 global auto tariff.2Federal Register. Implementing Certain Tariff-Related Elements of the United States-Japan Agreement
- Civil aircraft products from Japan are generally exempt from the reciprocal tariff, with the exception of unmanned aircraft.2Federal Register. Implementing Certain Tariff-Related Elements of the United States-Japan Agreement
- Generic drugs, pharmaceutical ingredients, and chemical precursors may be reduced to a zero reciprocal rate under the agreement.1The White House. Implementing the United States-Japan Agreement
- Natural resources not available domestically at sufficient scale may also qualify for a zero rate.1The White House. Implementing the United States-Japan Agreement
The Merchandise Processing Fee
Separate from the tariff, CBP charges a Merchandise Processing Fee on nearly every entry. For fiscal year 2026, formal entries (shipments valued over $2,500) pay 0.3464 percent of declared value, with a floor of $33.58 and a cap of $651.50. Paper filing adds a $4.03 manual surcharge.3U.S. Customs and Border Protection. Customs User Fee – Merchandise Processing Fees
Informal entries (generally $2,500 or less) pay a flat MPF of $2.69, $8.06, or $12.09 per shipment depending on entry type.3U.S. Customs and Border Protection. Customs User Fee – Merchandise Processing Fees
The Harbor Maintenance Fee
If your shipment arrives by ocean vessel, CBP also collects a Harbor Maintenance Fee of 0.125 percent of the cargo’s value. It does not apply to goods arriving by air or by international mail, and shipments small enough to qualify for informal entry are exempt.4eCFR. 19 CFR 24.24 – Harbor Maintenance Fee
The $800 Duty-Free Threshold No Longer Applies
For years, Section 321 of the Tariff Act let goods valued at $800 or less enter duty-free under the “de minimis” rule.5U.S. Customs and Border Protection. Section 321 Programs Effective August 29, 2025, that exemption was suspended globally for all non-postal shipments regardless of value or origin.6The White House. Suspending Duty-Free De Minimis Treatment for All Countries A $50 order from Japan now carries the same duty structure as a $5,000 shipment.
International postal mail is handled slightly differently. A February 2026 executive order continued the suspension but subjected postal items to a specific duty rate rather than the full tariff schedule that applies to courier and freight shipments.7The White House. Continuing the Suspension of Duty-Free De Minimis Treatment for All Countries Until CBP publishes a new entry process for postal shipments, they clear without a formal entry filing but still owe applicable duties.
A Worked Example
Say you buy industrial equipment from Japan for $10,000 and it ships by sea. Its HTS code has a Column 1 duty rate of 3 percent, so the reciprocal tariff tops it up to a combined 15 percent. Here’s the math:
- Duty at 15 percent: $1,500
- MPF at 0.3464 percent of $10,000: $34.64
- HMF at 0.125 percent of $10,000: $12.50
- Total customs cost: about $1,547
The same item shipped by air would skip the HMF and total roughly $1,535. Neither figure includes broker fees or a bond premium if one applies.
Formal vs. Informal Entry and Bonds
Shipments valued at $2,500 or less generally qualify for informal entry, which uses simpler paperwork and lower fees.8eCFR. 19 CFR Part 143 Subpart C – Informal Entry Most personal imports from Japan fall here. No customs bond is required, and the buyer can file the entry directly.
Above $2,500, a formal entry is required, and that means a customs bond. A single-entry bond covers one shipment; its amount is tied to the merchandise value plus duties and fees, and you pay a small percentage of that bond amount as a premium to a surety company. Frequent importers can buy a continuous bond covering all entries for the calendar year, and the application must include the total customs duties accrued on all imports during the previous calendar year.9eCFR. 19 CFR Part 113 – CBP Bonds
How You Actually Pay
For most personal imports, you never deal with CBP directly. Your carrier, whether FedEx, UPS, DHL, or another, clears the shipment through customs and bills you for duties and fees before delivering. Each carrier adds its own brokerage service charge on top of what’s owed the government.
If you file entries yourself or use a licensed customs broker, payment goes to CBP through ACH transfer, check, or money order made payable to U.S. Customs and Border Protection.10eCFR. 19 CFR 24.1 – Collection of Customs Duties, Taxes, Fees, Interest, and Other Charges Credit cards are accepted for non-commercial entries at CBP locations equipped to process them, and Pay.gov handles online payments.11eCFR. 19 CFR 24.22 – Fees for Certain Services
Why Classification Matters
The HTS code you declare drives every number above. Get it wrong and CBP treats it as underpayment, with civil penalties up to two times the underpaid duties for negligence, up to four times for gross negligence, and up to the full domestic value of the merchandise for fraud.12Office of the Law Revision Counsel. 19 USC 1592 – Penalties for Fraud, Gross Negligence, and Negligence Intent isn’t required for a penalty to attach. If your product sits near a tariff boundary or in a category with unusual treatment, it’s worth confirming the code before entry rather than after.
