# How do I work out my USA Duties and Tariffs I will pay for my products

## How to work out USA Duties and Tariffs

U.S. Customs calculates Duty and Tariff fees **as a percentage of the total declared commercial value** of the goods that are shipped.

Please note: The Trump administration has imposed an additional 30% Tariff on products made in China which is made up of a 20% Fentanyl Tariff plus a 10% additional Tariff, it is important that you remain aware of any changes that may happen to these additional Tariffs as they may change at any time.

Here is an example:

### 📦 Example Calculation

* **Per-unit value**: $8.70
* **Duties & Tariffs**: 57.4%
* **Scenario 1**: 150 units = $1,305

* Import Charges = 57.4% of $1,305 = **$749.07**
* **Scenario 2**: 300 units = $2,610

* Import Charges = 57.4% of $2,610 = **$1,498.14**

### 🔁 Keep in Mind

* The **unit cost** declared to Customs must match your supplier invoice (commercial invoice).
* **Tariff changes**, even mid-shipment, can affect what’s payable at the port.
* You may save on **per-unit shipping costs** by consolidating, but the **taxes scale linearly** with commercial value.
* There are additional Port fees when shipments enter the USA, they are a 0.12% Harbor  
Maintenance fee and a 0.35% Merchandise Process fee, there may also be Credit/Debit Card processing fees.
