How Import Duties Work in United States
Import duties in the United States are primarily levied as ad valorem rates, meaning they are calculated as a percentage of the imported product's customs value. Unlike many other countries, the U.S. does not have a national Value Added Tax (VAT) system. However, state-level sales taxes may apply to imported goods once they are sold within the U.S. market, post-importation.
The U.S. Customs and Border Protection (CBP) is the federal agency responsible for administering and enforcing import regulations and collecting duties. Importers are required to obtain a CBP importer number, which can be their IRS Employer Identification Number (EIN) or a Social Security Number (SSN) for individuals.
The total landed cost of an imported item in the U.S. can be estimated using the following formula:
Total Landed Cost = (Product Value + International Shipping Cost + Insurance Cost) * (1 + HTS Duty Rate) + Customs Broker Fees + Port Charges + Domestic Transportation + Applicable State Sales Tax (post-import)
It's crucial to note that certain goods may be subject to additional tariffs or surcharges. For example, Section 301 tariffs have been imposed on a wide range of goods originating from China, significantly increasing their import cost. Other special duties, such as anti-dumping and countervailing duties, may also apply to specific products found to be unfairly priced or subsidized.
HTS Code Structure
The Harmonized System (HS) is a globally standardized system of names and numbers for classifying traded products, developed and maintained by the World Customs Organization (WCO). It provides a universal 6-digit code for most products.
In the United States, this global 6-digit HS code is extended to a 10-digit Harmonized Tariff Schedule (HTS) code. The first six digits align with the international HS code, providing global consistency. The subsequent four digits (known as statistical suffixes) are specific to the U.S. and allow for more granular classification and data collection, often impacting the specific duty rate applied.
For example:
- HS Code: 8471.30
- Description (6-digit HS): Automatic data processing machines, portable, weighing not more than 10 kg, consisting of at least a central processing unit, a keyboard and a display.
- U.S. HTS Code: 8471.30.0100
- Description (10-digit HTS): Portable automatic data processing machines, weighing not more than 10 kg, consisting of at least a central processing unit, a keyboard and a display, with a flat panel display.
This extension allows the U.S. to differentiate between various types of portable data processing machines, potentially applying different duty rates or collecting specific trade statistics based on the display type or other characteristics.

Import Requirements
Importing into the United States involves adherence to various regulations and documentation requirements, administered primarily by U.S. Customs and Border Protection (CBP) and other partner government agencies (PGAs).
Required Licenses/Registrations:
- CBP Importer Number: Required for all commercial imports, typically the importer's IRS EIN or SSN.
- FDA Registration: For food, drugs, medical devices, and cosmetics.
- EPA Compliance: For vehicles, engines, and certain chemicals.
- USDA Permits: For plants, animals, and agricultural products.
- FCC Authorization: For radio frequency devices (e.g., electronics with Wi-Fi or Bluetooth).
- DOT Compliance: For vehicles and vehicle parts.
Key Documentation:
- Commercial Invoice: Details of the transaction, including seller, buyer, product description, quantity, value, and terms of sale.
- Packing List: Itemizes the contents of each package, including weight and dimensions.
- Bill of Lading (for ocean freight) or Air Waybill (for air freight): Contract between the shipper and carrier.
- Entry Summary (CBP Form 7501): The official document used to declare goods to CBP and calculate duties.
- Proof of Origin: Such as a Certificate of Origin, especially for goods claiming preferential treatment under FTAs (e.g., USMCA).
- Specific Permits/Licenses: Issued by PGAs as required for regulated goods.
Customs Process Overview:
- Arrival of Goods: Goods arrive at a U.S. port of entry.
- Entry Filing: Importer or their customs broker files entry documents with CBP, typically within 15 calendar days of arrival.
- Examination & Release: CBP may examine the goods and documents. Once satisfied, the goods are released from customs custody.
- Duty Payment: Duties, taxes, and fees are paid to CBP.
- Liquidation: CBP finalizes the entry, confirming the duties paid are correct.
How to Find the Correct HTS Code
Accurate HTS classification is critical for determining the correct duty rate, ensuring compliance, and avoiding penalties. Misclassification can lead to delays, fines, and even seizure of goods.
Classification Tips Specific to the U.S.:
- Start with the Official HTS: Always use the latest version of the U.S. Harmonized Tariff Schedule, available on hts.usitc.gov.
- General Rules of Interpretation (GRIs): The GRIs are the foundational principles for HTS classification. Understanding them is key to correctly classifying complex goods.
- Chapter and Section Notes: Pay close attention to the legal notes at the beginning of each HTS section and chapter, as they define the scope of headings and subheadings.
- Explanatory Notes: The World Customs Organization's Explanatory Notes provide detailed guidance on the interpretation of the HS headings and subheadings.
- Consult a Customs Broker: For complex or high-value shipments, engaging a licensed U.S. customs broker is highly recommended. They are experts in classification and compliance.
- CBP Rulings: For definitive classification, importers can request a binding ruling from CBP for specific products.
Common Mistakes:
- Using the 6-digit HS code instead of the 10-digit HTS: While the first six digits are global, the full 10-digit HTS is required for U.S. imports.
- Misinterpreting product function or material: The primary function, composition, and end-use are crucial for classification.
- Not considering all components: For goods made up of multiple components, the "essential character" rule often applies.
- Relying on supplier-provided codes without verification: Always verify codes provided by foreign suppliers, as they may not be familiar with U.S. HTS specifics.

Frequently Asked Questions
What is HTS?
HTS stands for Harmonized Tariff Schedule. It is the 10-digit classification system used in the United States to categorize all imported goods. The first six digits align with the international Harmonized System (HS) code, while the additional four digits provide further specificity for U.S. customs purposes, determining the applicable duty rates and collecting trade statistics.
How do I calculate import duty for the United States?
To calculate import duty, you typically multiply the customs value of your goods (often the transaction value, including freight and insurance to the U.S. port) by the specific ad valorem duty rate associated with its 10-digit HTS code. For example, if your goods are valued at $1,000 and the HTS duty rate is 2.5%, the duty would be $25. Additional fees, such as the Merchandise Processing Fee (MPF) and Harbor Maintenance Fee (HMF), may also apply, along with potential state sales tax post-import.
Is the HS code the same worldwide?
The first six digits of an HS code are generally consistent worldwide, as they are based on the international Harmonized System maintained by the World Customs Organization (WCO). However, countries extend this 6-digit code with additional digits (e.g., 10 digits in the U.S. HTS, 8 digits in the EU TARIC) to meet their specific tariff and statistical needs. Therefore, while the core classification is global, the full national code is country-specific.
Do I need a license to import into the US?
While a general import license is not required by CBP for most goods, many specific products are regulated by other U.S. government agencies (PGAs) and may require permits, licenses, or certifications. Examples include food and drugs (FDA), vehicles (EPA/DOT), firearms (ATF), and certain agricultural products (USDA). It's essential to identify all relevant PGAs for your specific product before importing.
What are Section 301 tariffs?
Section 301 tariffs are additional duties imposed by the U.S. government under Section 301 of the Trade Act of 1974. These tariffs are typically levied on goods from countries deemed to be engaging in unfair trade practices. Most notably, Section 301 tariffs have been applied to a wide range of products originating from China, significantly increasing their cost of import into the United States.
