HS Code Lookup — Complete Classification Guide

• Chapters 01–97: The HS divides all goods into 97 chapters grouped within 21 sections. Chapter 01 starts with live animals; Chapter 97 covers works of art.
• Headings (4 digits): Each chapter contains multiple headings that narrow the classification. For example, Chapter 62 has headings for suits (6203), dresses (6204), shirts (6205), and more.
• Subheadings (6 digits): The subheading level adds material or attribute specificity. The first 6 digits are internationally harmonized — meaning HS 6205.20 is "men's cotton shirt" everywhere in the world.
• National Extensions (8-10+ digits): Countries add additional digits beyond the 6-digit HS core. The US uses 10-digit HTS codes, the EU uses 8-digit TARIC codes, and the UK uses 10-digit commodity codes.

• Duty Rate: A one-digit difference can mean 0% duty vs. 25%. For example, HS 8471.30 (laptops) carries 0% duty in the US, while HS 8528.72 (monitors) attracts up to 5%.
• FTA Eligibility: Free Trade Agreement preferential rates only apply to specific HS codes. Using the wrong code means you lose access to reduced or zero-duty rates under agreements like USMCA, CPTPP, or the EU-UK TCA.
• Anti-Dumping Duties: Certain HS codes trigger AD/CVD (Anti-Dumping/Countervailing Duty) orders that can add 50%–250% to your landed cost.
• Import Licensing: Some HS chapters require special permits — Chapter 93 (arms), Chapter 28/29 (chemicals), and Chapter 30 (pharmaceuticals) often need regulatory clearance.
• Customs Penalties: Intentional or negligent misclassification can result in fines of up to 4x the underpaid duty in the US, and criminal prosecution in extreme cases.

1. GRI 1: Classification is determined first by the terms of the headings and any relative section or chapter notes. This is the primary rule — always start here.
2. GRI 2(a): Incomplete or unfinished articles are classified as if they were complete, provided they have the essential character of the finished product.
3. GRI 2(b): Mixtures and combinations of materials are classified in the heading covering the component that gives the product its essential character.
4. GRI 3: When goods could fall under two or more headings, classify under the heading that provides the most specific description.
5. GRI 4: Goods that cannot be classified under GRI 1-3 are classified under the heading for goods most akin to them.
6. GRI 5-6: Rules for packaging materials and subheading-level classification.

Understanding these rules is critical because they override intuitive classification. For example, a stainless steel water bottle might seem like a "drinking vessel" (Chapter 69/70), but GRI 1 and the chapter notes classify it under Chapter 73 (steel articles) based on material composition.

The first 6 digits are always the same internationally. For example, HS 8471.30 means "portable data processing machines" everywhere. But the US extends this to 8471.30.0100 (with battery) vs. 8471.30.0150 (without battery), and each carries a different statistical suffix.

1. Identify the product's essential character: What is it made of? What does it do? Who uses it? A "Bluetooth speaker shaped like a rubber duck" is classified by its function (sound reproduction → Chapter 85), not its shape.
2. Find the HS Chapter (2-digit): Browse the 21 HS sections, starting with the section that best matches the product's primary material or function.
3. Narrow to the Heading (4-digit): Within the chapter, read the heading descriptions and chapter notes. Some headings have legal exclusions — always check the "does not include" notes.
4. Select the Subheading (6-digit): Drill down by material composition, intended use, or manufacturing process. This is where most classification disputes occur.
5. Add country-specific digits: Use your destination country's tariff tool to find the full national code. For the US, use the USITC search. For the EU, use TARIC.
6. Validate with our AI tool: Use our AI-Powered HS Code Finder to cross-check your classification with confidence scoring and alternative suggestions.

1. Classifying by end-use instead of material: A stainless steel thermos flask classifies under Chapter 73 (steel articles), NOT Chapter 96 (miscellaneous goods) — even though it's used for drinking.
2. Ignoring chapter notes: Chapter notes legally override heading descriptions. Chapter 85 Note 5 specifies exactly what counts as an "automatic data processing machine" — many electronics are misclassified by ignoring this.
3. Using outdated codes: The WCO revises the HS every 5 years (latest: HS 2022). Codes from 2017 or earlier may no longer exist or may have been re-numbered.
4. Assuming the same code works everywhere: While the first 6 digits are global, national extensions differ. HS 8471.30 is universal, but the 10-digit US HTS code differs from the 8-digit EU CN code.
5. Classifying multi-component goods by the most expensive part: GRI 3(b) says you classify by essential character, not by value. A $200 leather case containing a $5 pen set classifies under the pen heading, because the pen gives the product its essential character as a "writing set."

Each revision adds new subheadings for emerging products (e.g., drones, e-cigarettes, 3D printers were added in recent revisions), splits existing codes for better statistical tracking, and removes obsolete classifications. Countries typically have a transition period of 6-12 months to adopt new versions into their national tariff schedules.

Between major revisions, individual countries frequently update their national extensions (digits 7-10) and duty rates through budget announcements, SROs, or Federal Register notices — sometimes multiple times per year.
