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).
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 301 Tariffs: An additional duty (often 25%) applied to many Chinese goods. This planner allows you to toggle it on/off as a planning estimate.
Section 232 Tariffs: A specific 25% tariff on steel/aluminum/semiconductors.

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 301 Tariffs

Since 2018, the US government has imposed additional tariffs on goods of Chinese origin under "Section 301". These tariffs often add a flat 25% on top of the base duty. Our calculator allows you to toggle this on or off to see the impact on your bottom line.

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.
