Understanding Your Customs Charges (FY2026)
- Customs Value: Duties are calculated on the FOB (Free on Board) value of your goods, meaning the invoice price paid to your supplier (excluding shipping/insurance).
- MPF (Formal Entry): The Merchandise Processing Fee is mandatory for formal entries. It is calculated at 0.3464% of the customs value, with a strict minimum of $33.58 and a maximum cap of $651.50 (FY2026 rates). Informal entries valued at $2,500 or less typically pay a small flat automated fee instead.
- Harbor Maintenance Fee (HMF): A 0.125% fee applied only if you import via Ocean Freight to a US port. It is not charged for Air Freight.
- Section 122 Tariff: A temporary 10% tariff is currently modeled as default-on for China planning estimates. It is scheduled to expire around 2026-07-24 unless extended.
- Section 301 Tariffs: Additional China-specific duties vary by product classification, often around 25% but ranging much higher for some categories. Use the editable rate field when you know your product's rate.
- Section 232 Tariffs: Product-specific trade-remedy duties can apply to categories such as steel, aluminum, copper, autos, semiconductors, and lumber. Use the editable rate field as a planning estimate.
How This China to USA Import Duty Calculator Works
Importing goods from overseas involves more than just paying your supplier. To run a profitable business, especially for Amazon FBA or D2C brands, you must understand your true "Landed Cost". This China to USA import duty calculator is designed to reveal the hidden fees that eat into your margins.
Understanding Landed Cost
Landed cost represents the total price of a product once it has arrived at your warehouse or fulfillment center. It includes the original FOB product cost (Free On Board), shipping fees, cargo insurance, and all US Customs duties and taxes. Ignoring any of these variables can lead to selling products at a loss.
Import Duty from China to USA
The base import duty is determined by the Harmonized System (HS) Code of your product. While some electronics may have a 0% base rate, garments and textiles can be as high as 32%. However, for Chinese imports, the base rate is rarely the only charge.
Section 122, Section 301, and Section 232 Tariffs
As of the latest verification, this planner includes a default-on 10% Section 122 tariff for the common China import case. It is temporary and scheduled to expire around 2026-07-24 unless extended. China-origin goods may also face Section 301 tariffs that vary by product, plus Section 232 trade-remedy tariffs for specific product groups. The editable rate fields let you model the rate you confirm for your HS code.
Customs Fees: MPF and HMF
Beyond duties, Customs and Border Protection (CBP) collects administrative fees:
- MPF (Merchandise Processing Fee): For formal entries (shipments over $2,500), CBP charges an ad valorem rate. As of FY2026 models, this is typically estimated at 0.3464% of the FOB value, with a minimum floor (~$33) and a maximum ceiling (~$651).
- HMF (Harbor Maintenance Fee): If your goods arrive via ocean freight at a US port, an additional 0.125% fee is applied to maintain port infrastructure. This fee does not apply to air freight.
Why Margins Matter for FBA Sellers
Amazon FBA fees (referral and fulfillment) typically take 30-40% of your sale price. When you add advertising costs (PPC), your remaining margin is thin. That's why knowing your accurate landed cost per unit is critical. A "Go / No-Go" decision should be based on data, not guesses.
Frequently Asked Questions
How do I calculate customs charges from China to USA?
To calculate customs charges, add the Base Duty (Product Value x Duty Rate), Section 122 tariff if active, any applicable Section 301 or Section 232 tariff, the Merchandise Processing Fee (MPF), and the Harbor Maintenance Fee (HMF) for ocean shipments. This calculator automates that math for planning estimates.
What are the current import taxes China to USA?
Import taxes vary by product and entry date. Most China shipments should plan for Base Duty, the temporary 10% Section 122 tariff while active, and possible Section 301 or Section 232 tariffs depending on classification. MPF and, for ocean freight, HMF may also apply.
Where can I find China to USA import duty rates?
Official rates are listed in the Harmonized Tariff Schedule of the United States (HTSUS). Search your specific HS code on the USITC website, then check Chapter 99 and trade-remedy guidance for extra tariffs such as Section 122, Section 301, or Section 232.
What is MPF in US imports?
MPF stands for Merchandise Processing Fee. Formal entries valued over $2,500 use a percentage calculation with a strict minimum and maximum fee. Informal entries valued at $2,500 or less typically use a small flat automated fee instead.
What is HMF in shipping?
HMF stands for Harbor Maintenance Fee. It is charged at a rate of 0.125% of the cargo value for goods unloaded at US ports via ocean freight. It helps fund the dredging and maintenance of harbors.
