The 4-Step Tariff Calculation Process
Calculating import tariffs follows a systematic process. This flow shows the essential steps from identifying your product to calculating the final duty owed. Each step is critical for ensuring compliance and accurate cost assessment.
Find HS Code
Classify your product using the Harmonized System (HS) code. This universal code determines the tariff rate.
Determine Customs Value
Calculate the total value of your goods, including product cost, shipping, and insurance, as declared to customs.
Identify Tariff Rate
Look up the duty rate in the Harmonized Tariff Schedule (HTS) using your HS code and country of origin (China).
Calculate Total Duty
Multiply the customs value by the tariff rate(s) to find the total duty payable. Include any additional tariffs.
Key Factors Determining Tariffs
The total tariff cost isn't based on a single number. It's a combination of several critical factors. Use the tabs below to explore each component and understand its role in the final calculation.
What is an HS Code?
The Harmonized System (HS) code is a globally standardized system of names and numbers to classify traded products. Customs authorities use HS codes to identify products when assessing duties and taxes. The first six digits are universal, with additional digits added by individual countries for more specific classification. For US imports, this is the Harmonized Tariff Schedule (HTS) code. An incorrect HS code is a common and costly mistake, potentially leading to fines and shipping delays.
Example Tariff Rates by Category
Tariff rates vary significantly across different product types. This chart illustrates the potential combined tariff rates (base duty + Section 301) for several common import categories from China, showing how costs can differ. Interact with the bars to see the detailed breakdown.
