# How Do I Estimate Customs Duties?

Import customs duties are not included in your Flexport quote, but you can estimate them using the [HTS Code](https://www.flexport.com/help/219/) of your product:

1. Enter your HTS Code in the [HTS Search bar](https://hts.usitc.gov/):

You can also use Flexport's [duty rate calculator](https://www.flexport.com/tools/duty-estimator) to look up your product's duty rate without the HTS code. 

2. Multiply the duty rate by the total value of your imported products ([found on the commercial invoice](https://www.flexport.com/help/24/)) for an **estimation** of what you will need to pay in customs duties.  

[Anti-dumping or countervailing duties](https://www.flexport.com/help/199-what-are-anti-dumping-and-countervailing-duties) may also apply.

If the items you are importing have a [country of origin](https://www.flexport.com/glossary/country-of-origin/) of China, then Section 301 duties may also apply. You can search HTS codes [here](https://www.tuttlelaw.com/newsletter_links/5-31-23_exclusions_list.xlsx) to see if they have additional Section 301 Duties.
