Sign in blue and white stating 'Harmonized System Code HS,' relevant for international shipping regulations.

When shipping internationally, one of the most overlooked yet critical elements is HS code classification. One incorrect HS code can lead to costly fines, customs delays, and even seizure of shipments. For example, in India, over 50% of high-value electronics shipments faced clearance delays in 2023 due to HS code errors and incomplete documentation, and about 90% of customs-related cases involved HS code issues.

This guide walks you through the HS code classification process step-by-step, highlights common customs classification mistakes, and shows how trusted logistics partners like Atlantic International Express help navigate the complexities of tariff code lookup and customs compliance with confidence.


What are HS codes, and why do they matter?

HS Code stands for Harmonized System Code. It is an internationally standardized system of names and numbers developed by the World Customs Organization (WCO) for classifying traded products.

HS Code is a six-digit number. The first four digits identify the product's chapter and heading, while additional digits provide more specific subheadings based on product details like raw materials or country-specific variations.

Lets consider an example:HS Code 620520

  • 62 : (Chapter) : Articles of apparel and clothing accessories, not knitted or crocheted.

  • 05 : (Heading) : Men's or Boys' Shirts.

  • 20 : (Subheading) : The remaining digits specify the type of men's or boys' shirts, such as those made from cotton.

A tariff code lookup is the process of using a trade tariff tool or database to identify the HS code for a product. We offer the best-in-class tariff code lookup tool to identify the HS Code for your product. Click here to know more.


Why are HS codes important?

  • Correct Classification : Accurately classifying a product using its tariff code ensures compliance with international trade regulations.

  • Duty Determination : The code determines the applicable import or export duty and other taxes.

  • Customs Clearance : A correct tariff code speeds up customs clearance and prevents delays, product seizures, or penalties.

  • Trade Compliance : It's crucial for fulfilling all import and export documentation requirements.

  • Trade Statistics : They help the concerned authorities to collect and analyse trade statistics and gain new insights.


Step-by-Step Guide to HS Code Classification

Here’s how you can accurately classify your goods and ensure a smoother transit.

  • Understand the Product in Detail

    Start with a clear description:

    • What is it made of?
    • How is it used?
    • Is it finished or a component?

    Example:

    • A plastic toy doll might fall under HS code 9503.00
    • A wooden puzzle could be classified under 9503.60

    Though both are toys, material and function affect classification.

  • Use Tariff Code Lookup Tools

    Leverage official databases like:

    • WCO Harmonized System Database
    • National Customs Portals
    • Atlantic International Express’s HS Code Lookup Tool

    These tools help narrow down potential codes based on product attributes.

  • Apply the General Rules of Interpretation (GRI)

    • The GRI framework helps resolve classification ambiguities. There are 6 of them. They are as follows:
    • GR1 - Legal Interpretation of Headings
    • GR2 - Incomplete and Unassembled Goods
    • GR3 - Goods Classifiable Under Two or More Headings
    • GR4 - Classification of Unspecified Goods
    • GR5 - Packaging and Containers
    • GR6 - Subheading Classification

    For more information, visit our website and the World Customs Organization's official website.

  • Consult Binding Rulings

    Binding rulings are official decisions from customs authorities that acknowledge the correct classification. They’re especially useful for complex or hybrid products.

    Example: A company importing multi-functional smartwatches received a binding ruling classifying them under 8517.62 (telecommunication devices), not 9102.00 (watches), due to their primary function.

    Atlantic International Express can help you secure binding rulings and let you focus on other important business aspects.


Common HS Code Classification Mistakes

Even experienced shippers can misclassify goods, leading to delays, fines, or rejected shipments. Below is the list of most common mistakes to avoid:

  • Vague Descriptions : Using generic terms like “device” or “accessory” without specifying material, use, or function.

  • Ignoring Composition : Not taking the exact composition for the goods to be shipped. For example: cotton vs. polyester shirts, plastic vs. wooden toys, etc.

  • Multi-Function Confusion : ncorrect classification due to confusion between primary and secondary features. For instance, A smartwatch should be categorized as a telecommunication device and not a watch.

  • Outdated Codes : HS codes are regularly updated. Using old versions can cause compliance issues.

  • Assuming Similarity : HS codes are properly designed to differentiate similar products based on what are sometimes considered very minor differences. Most products are assumed to be similar and the wrong HS code on them will cause compliance errors.

  • Skipping Country-Specific Digits : The first six digits are global, but additional digits vary by country and affect duties.
