Many importers lose thousands each year because they misunderstand US customs import duty rates. A simple misclassification or missed exemption can drive costs up and hurt your margins. At Velotactics Logistics, we help importers uncover hidden savings, optimize tariff classifications, and stay fully compliant—so every shipment enters the U.S. at the lowest possible cost.
What Are US Customs Import Duty Rates and Why Do They Matter?
US customs import duty rates are tariffs imposed by U.S. Customs and Border Protection (CBP) on imported goods. These duties protect domestic industries and generate revenue. Each product has its own Harmonized Tariff Schedule (HTS) code that determines the duty rate—ranging from 0% to 37.5%.
A clear understanding of these rates allows importers to accurately calculate landed costs, plan pricing, and stay competitive.

How Are US Customs Import Duty Rates Calculated?
The total import duty is determined using the following formula:
Duty = (Customs Value Ă— Duty Rate) + Merchandise Processing Fee (MPF) + Harbor Maintenance Fee (HMF)
| Component | Description | Typical Rate |
|---|---|---|
| Duty Rate | Determined by HTS code | 0%–37.5% |
| MPF | Merchandise Processing Fee | 0.3464% (min $31.67, max $614.35) |
| HMF | Harbor Maintenance Fee (for ocean freight) | 0.125% of shipment value |
Example:
Importing $50,000 of machinery at a 4% rate by sea freight:
(50,000 Ă— 0.04) + (50,000 Ă— 0.003464) + (50,000 Ă— 0.00125) = $2,188.20 total duty cost.
What Factors Influence Duty Rates?
Several key factors determine your duty rate:
- Product Type: Each category in the HTS schedule has a unique rate.
- Country of Origin: Imports from FTA countries often qualify for reduced or zero duty.
- Declared Value: The higher the value, the higher the total duties.
- Shipping Method: While the rate itself stays constant, ocean shipments include HMF.

How to Find Your Product’s Correct HTS Code
Using the wrong HTS code is one of the most common—and costly—import errors. It can cause overpayment or fines.
Example:
- 9503.00.0073 (toys) → 0% duty
- 9403.60.8081 (furniture) → 3.2% duty
By partnering with Velotactics Logistics, importers gain access to classification experts who review invoices, product details, and compliance notes to ensure correct coding.

Proven Ways to Lower US Customs Import Duty Rates
1. Use Free Trade Agreements (FTA):
Leverage agreements like USMCA or GSP to reduce or eliminate duties.
2. Apply for Duty Drawback:
Reclaim duties for goods that are re-exported or unused.
3. Claim De Minimis Exemption:
Shipments under $800 can enter the U.S. duty-free.
4. Review Product Classification:
Small wording differences in HTS codes can change rates significantly.
5. Optimize Packing and Valuation:
Repackaging or adjusting declared components can lower the dutiable amount.
