Online purchase from UK how much duty us customs tax?

When you make an online purchase from the UK to the US, the customs duty you may owe depends on the value of the goods and their classification under the Harmonized Tariff Schedule. Generally, items valued under $800 can enter the US duty-free due to the de minimis rule. However, if the value exceeds this threshold, duties can range from 0% to over 30%, depending on the product category. Additionally, state sales tax may apply depending on your location.
