US Import Duties & Landed Cost Calculator
Estimate customs duty, MPF, HMF, and total landed cost for goods entering the United States.
What a US duties calculator helps you do
A duties calculator us tool helps you estimate what it really costs to import products into the United States. Many importers focus only on supplier cost and freight, then get surprised by customs charges. A good estimate combines duty, processing fees, and extra landed costs into one view so your margins stay intact.
This calculator is designed for fast planning. It is useful for ecommerce sellers, small importers, first-time buyers, and anyone comparing sourcing options from different countries.
How US import charges are typically built
In most shipments, the total import cost includes more than one line item. Here are the most common pieces:
- Customs duty: A percentage based on classification (HTS code) and customs value.
- MPF (Merchandise Processing Fee): Usually applies to formal entries, with a rate and a minimum/maximum cap.
- HMF (Harbor Maintenance Fee): Commonly tied to ocean shipments.
- Brokerage/customs clearance fees: Charged by your broker or carrier.
- Freight and insurance: Logistics costs that affect landed cost even when not directly dutiable.
- Sales/use tax: May apply depending on your business structure and destination state rules.
How to use this duties calculator us tool
1) Enter your product value
Use your declared customs value (often similar to FOB value for planning). This number drives most percentage-based import fees.
2) Add your duty rate
Use the duty percentage tied to your HTS classification. If you are unsure, ask your customs broker before finalizing pricing.
3) Add freight, insurance, and brokerage
These are real out-of-pocket costs and should be in every landed cost estimate, especially for marketplace and DTC pricing models.
4) Select entry type and transport mode
Formal entries can trigger MPF. Ocean shipments can trigger HMF. The calculator applies these automatically based on your selections.
5) Include tax if relevant
If you need a fuller delivered-cost view, include an estimated sales/use tax rate.
Quick example
Suppose you import goods with a customs value of $1,000 and a 5% duty rate. You also pay $120 shipping, $15 insurance, and $45 brokerage. If you file as formal entry and ship by ocean, your estimate includes duty + MPF + HMF in addition to logistics fees. This gives a realistic landed cost you can use for pricing and profit planning.
Important notes about US customs estimates
- De minimis threshold: Some low-value shipments may clear differently (commonly referenced as $800), but rules and enforcement can vary by shipment profile.
- Trade remedies: Section 301, Section 232, antidumping/countervailing duties can significantly change results.
- Classification matters: A small HTS change can produce a very different duty rate.
- Origin and special programs: Preferential rates may apply when program requirements are met.
- Regulatory holds: PGA agencies (FDA, USDA, etc.) may add timing and cost.
Best practices for better landed cost forecasting
Build a repeatable import worksheet
Track per-SKU duty rate, broker fee assumptions, freight method, and average clearance cost. Use the same method every purchase cycle.
Quote multiple freight paths
Air may reduce lead times but raise logistics spend. Ocean may lower freight cost but add HMF and longer cash conversion cycles.
Review classifications annually
Product updates, material changes, and legal rulings can affect HTS treatment over time.
