HS Code Search

An HS code (Harmonized System) is an internationally standardized tariff classification number maintained by the World Customs Organization (WCO). Over 200 countries use this system to classify goods in cross-border trade. The Harmonized System covers more than 5,000 commodity groups organized into 97 chapters and 21 sections.

The structure follows a clear hierarchy: the first 2 digits identify the chapter (e.g. 84 = Machinery), the first 4 digits identify the heading (e.g. 8471 = Data processing machines), and all 6 digits identify the subheading (e.g. 8471.30 = Portable data processing machines). Each country adds further digits for national detail: the US and EU each use 10-digit codes (HTS and TARIC respectively), as does the United Kingdom.

1. Identify material and function: Determine the primary material and principal use of your goods. Classification is based on objective characteristics, not brand names.
2. Start broad: Begin with the relevant section (e.g. Section XVI: Machinery and electrical equipment) and work down to the chapter.
3. Narrow to the heading: Read the chapter notes carefully. These define which goods are included or excluded.
4. Find the 6-digit code: Select the subheading that most precisely describes your product.
5. Verify with customs: Confirm your classification through a binding tariff ruling or consult a licensed customs broker.

The fastest starting point is the search tool above: enter a product description and compare results against official tariff data.

• Classifying by brand name instead of function: Customs classifies by what a product is, not how it is marketed. A "gaming chair" is classified as seating furniture, not gaming accessories.
• Ignoring the "essential character" rule: For goods made from multiple materials, the material that gives the item its essential character determines classification. A nylon backpack with leather trim is classified under the nylon component.
• Confusing "parts" versus "accessories": Parts (components necessary for function) and accessories (optional additions) often fall under different headings with different duty rates.
• Not checking exclusion notes at the chapter level: Every chapter starts with notes that explicitly exclude certain goods. These notes take precedence over heading descriptions.

For standard goods, self-classification is often sufficient. However, professional advice from a licensed customs broker is strongly recommended in the following situations:

• High-value shipments: For consignments above $10,000, an incorrect classification can result in significant back-duties, penalty charges, or customs delays.
• Ambiguous classification: When your goods could fall under multiple headings, a broker can determine the correct classification using the General Rules of Interpretation (GRI).
• Preferential tariff rates: Claiming reduced duty rates under Free Trade Agreements (FTAs) requires correct application and documentation of rules of origin.
• Restricted or regulated goods: Products requiring import licenses, permits, or special markings should always be handled with professional guidance.
