How It Works
This calculator estimates US import duties and tariff surcharges based on product category, country of origin, and declared value. It calculates the total landed cost including shipping and all applicable duties.
The basic rule:
- Dutiable value = declared product value + shipping and insurance costs
- Base duty = dutiable value × applicable HTS duty rate for product category
- Tariff surcharges applied based on country of origin (e.g., Section 301 tariffs on Chinese goods)
- Total landed cost = declared value + shipping + base duty + tariff surcharges + processing fees
Duty rates shown are general estimates based on common HTS categories. Actual rates depend on the specific HTS code, which is determined by detailed product classification. For exact rates, consult the US International Trade Commission's Harmonized Tariff Schedule or a licensed customs broker.
Tips & Considerations
- Double-check your product category before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both base duty and tariff surcharge — they work together to give you the full picture.

Frequently Asked Questions
How are US import duties calculated?
US import duties are based on the dutiable value (product cost + shipping + insurance) multiplied by the applicable duty rate from the Harmonized Tariff Schedule (HTS). Rates vary by product classification and can range from 0% to over 25%. Additional tariff surcharges may apply based on country of origin.
What are Section 301 tariffs on Chinese goods?
Section 301 tariffs are additional surcharges on goods imported from China, ranging from 7.5% to 25% on top of regular duty rates. They cover thousands of product categories and were implemented starting in 2018. Some exclusions exist but many products face the full surcharge.
Is there a duty-free threshold for imports?
Yes, the de minimis threshold for US imports is $800 per person per day. Shipments valued under $800 are generally duty-free. However, this does not apply to commercial shipments, goods subject to quotas, or certain restricted items.
Do I pay duty on the shipping cost too?
Yes. US Customs calculates duty on the 'dutiable value,' which includes the product cost, shipping/freight charges, and insurance. This is known as CIF (Cost, Insurance, Freight) valuation. The shipping cost is added to the declared value before the duty rate is applied.
What is the Merchandise Processing Fee?
The Merchandise Processing Fee (MPF) is 0.3464% of the dutiable value, with a minimum of $31.67 and maximum of $614.35 per entry. It applies to most formal entries (goods valued over $2,500). There is also a Harbor Maintenance Fee of 0.125% on ocean shipments.
Can I reduce import duties legally?
Yes. Options include: using Free Trade Agreement (FTA) preferences (USMCA for Mexico/Canada), applying for duty drawback on re-exported goods, using Foreign Trade Zones, properly classifying products under the most favorable HTS code, and structuring imports to use the de minimis threshold where applicable.
