Understanding HSN/HTS Codes for Car Repair Services in the U.S

May 22, 2025

Car Repair Services

Many vehicle owners don’t realize that an entire classification system is used to categorize car repair services and auto parts, especially for import, export, and tax purposes. At Kwik Kar Auto Dallas, we want to help our customers and local community understand how these codes work and why they matter.

What Are HSN, HTS, and Schedule B Codes?

  • HSN (Harmonized System of Nomenclature): An international system created by the World Customs Organization to classify goods. It’s widely used for customs and trade.
  • HTS (Harmonized Tariff Schedule): The U.S. version of the HS code, used for imports. The first 6 digits match the global HS code, and the last 4 digits are specific to U.S. tariffs and regulations.
  • Schedule B Codes: Used for exporting goods from the U.S. These codes are also based on the HS system but are maintained by the U.S. Census Bureau.

Why These Codes Matter for Car Owners and Auto Shops?

If you’re in the business of importing car parts or planning to ship something internationally, these codes determine the duties, taxes, and classification for:

  • Brake pads
  • Engine components
  • Tires
  • Lubricants
  • Diagnostic tools
  • Service labor and repair charges

For example, replacing an imported alternator might involve a different HTS code than replacing tires, and the tax rate could vary.

How to Look Up These Codes

Here are some official resources to help you find the correct classification:

You can search by keyword (e.g., “brake rotor” or “car battery”) to find the right code.

GST and HSN Codes for Vehicle Services in the U.S.

While GST (Goods and Services Tax) is not a system used in the United States, the concept of service classification is still relevant. Invoices for repair and car maintenance services often include line items for:

  • Labor
  • Parts
  • Environmental fees

Each of these may have different treatment when it comes to reporting and taxation, especially for commercial vehicle fleets.

FAQs

1. What is the HSN code for car repair services in the U.S.?
The U.S. does not use “HSN codes” in the same way as countries like India. Instead, the Harmonized Tariff Schedule (HTS) is used for imports, and Schedule B codes are used for exports. Car services typically don’t require these unless importing or exporting parts.

2. How can I find the HTS code for car parts?
Visit https://hts.usitc.gov/ and use the search bar to enter your product description (e.g., “radiator” or “oil filter”). This will show the HTS code and tariff rate.

3. Is there a PDF list of U.S. tariff codes?
Yes. You can download a PDF version of the Harmonized Tariff Schedule directly from https://hts.usitc.gov/current.

4. Do I need a Schedule B code for domestic repairs?
No. Schedule B codes are only used when you’re exporting goods from the U.S. Domestic repairs do not require one.

5. Can Kwik Kar Auto Dallas help with part classifications?
While we don’t offer import/export services, our technicians can guide you on parts commonly sourced from global suppliers and help you identify key components on your invoice for further research.

Understanding HS, HTS, and Schedule B codes may seem technical, but it’s an important part of modern automotive business and ownership.
