HS Codes
Essential Insights into HS Codes
- Universal Standard: HS Codes are a globally recognised 6-digit classification system governed by the World Customs Organisation (WCO), categorising over 98% of internationally traded goods.
- Key to Trade Compliance: HS Codes are essential for determining duties, tariffs, and taxes. Accurate classification ensures compliance with international trade laws and helps avoid costly delays, fines, or shipment rejections.
- National Variations Exist: While the first six digits are standardised worldwide, individual countries often extend HS Codes to 8–10 digits to meet local regulatory and tariff needs—for example, the United States uses the Harmonised Tariff Schedule (HTS).
What is an HS Code?
The Harmonised System (HS) code is a globally standardised numerical method for classifying traded products. Developed and maintained by the World Customs Organisation (WCO), the HS code is a universal “language” for international trade, used by more than 200 countries and economies. Think of it as a passport for goods, essential for smooth customs clearance and cross-border transactions.
The Global Standard for Trade
At its core, the HS system provides a uniform framework for identifying and categorising products worldwide. This consistency allows customs authorities across different countries to classify goods accurately and uniformly, regardless of their origin or destination. Today, approximately 98% of internationally traded goods are classified using the HS system.
Core Purpose: Facilitating Global Commerce
HS codes play a central role in international trade, supporting various critical functions:
- Tariff Application: Customs authorities use HS codes to calculate applicable duties, tariffs, and taxes (e.g., VAT, GST) for imported and exported goods.
- Trade Statistics: Governments and global organisations rely on HS codes to track trade volumes, assess market trends, and develop economic policies.
- Regulatory Compliance: HS codes ensure that goods meet regulatory requirements, such as product safety standards, environmental controls, import/export restrictions, and quotas.
- Trade Agreements & Negotiations: HS codes provide a standardised basis for negotiating and implementing trade agreements, including Free Trade Agreements (FTAS), simplifying tariff commitments and product classifications.
| Type | # of Digits | Import or Export? | Governed By | When They’re Used |
|---|---|---|---|---|
| HS Codes | 6 | Global Use | World Customs Organization | The universal classification tool. Used to reference classification with anyone outside the U.S. |
| HTSUS Codes | 10(HS for first 6 digits) | U.S. Import | U.S. International Trade Commission | These codes are specific to the U.S. and must be used by U.S. importers. They are not recognized globally. |
| Schedule B Codes | 10(HS for first 6 digits) | U.S. Export | U.S. Census Bureau | Companies that export typically use these codes. They’re a subset of the HTS and usually an easier way to classify products. lf you’re already classifying under HTS, it’s OK to use HTS for export, too. But certain HTS codes cannot be used for export. |
The Structure of HS Codes
The Harmonised System (HS) is logically organized and globally recognized for classifying traded products. It is managed by the World Customs Organisation (WCO) and structured hierarchically to ensure clarity and consistency in trade documentation.
Hierarchical Organization
- The HS is divided into 21 sections, with broad groupings based on product type or industry.
- These sections are subdivided into 99 Chapters, each representing a general category of goods.
- Chapters are further broken down into Headings and Subheadings, offering increasing levels of detail.
The International 6-Digit Framework
The standard HS code consists of six digits, which are universally accepted and used for customs classification worldwide. Its structure is as follows:
- First two digits (Chapter): Indicate the general product category.Example: Chapter 04 – Dairy produce; birds’ eggs; natural honey…
- Next two digits (Heading): Define a more specific grouping within the chapter.Example: 0406 – Cheese and curd
- Final two digits (Subheading): Provide detailed product identification.Example: 0406.10 – Fresh (unripened or uncured) cheese, including whey cheese and curd
National Adaptations: Beyond the 6 Digits
While the first six digits are standardized globally, individual countries often extend HS codes to include additional digits for national tariff and statistical purposes:
- United States – HTS Codes: The Harmonised Tariff Schedule of the United States (HTSUS) expands the HS code to 8–10 digits. The first six digits align with the international HS, while the additional digits are U.S.-specific and are used to determine exact duty rates and statistical reporting categories.
- European Union – Combined Nomenclature (CN): The EU uses an 8-digit CN code, which builds on the HS structure and adds EU-specific tariff and policy information.
Using the correct full national code for the country of import or export is essential to ensure compliance and avoid delays or penalties.
Why is the HS Code Important?
The accurate application of the HS Code is not just an administrative requirement; it’s essential for successful and compliant international trade operations. Incorrect classification can result in serious consequences.
Accurate Tariff and Tax Application
The HS Code directly determines the tariffs and taxes applied to a product. Misclassifying items can lead to overpaying taxes (which eats into profits) or underpayment (which can lead to penalties and legal action from customs authorities).
Ensure Trade Compliance and Avoid Penalties
Using the correct HS codes ensures compliance with various trade regulations, such as import/export licenses, quotas, anti-dumping duties, and health or phytosanitary requirements. Mistakes can result in cargo delays, customs detention, fines, cargo seizure, and, in severe cases, even criminal charges.
Critical for Trade Statistics and Policy
Governments rely on data gathered through HS codes to compile accurate trade statistics. This data is essential for understanding trade balances, spotting market trends, negotiating trade agreements, and shaping national economic and trade policies.
Simplify Logistics and Supply Chains
Logistics providers, freight forwarders, and customs brokers depend on HS codes to prepare shipping documents, manage clearance processes, and ensure efficient cross-border transportation. Correct coding helps streamline operations, making supply chains faster, more predictable, and more efficient.
Finding and Using HS Codes
Determining the correct HS code for your product is crucial for both importers and exporters. We offer a variety of resources to help you navigate this process.Key Resources for HS Code Lookup
Official Government Customs Websites: Most countries and regions provide online tools or access to their national tariff schedules. For instance, the U.S. International Trade Commission (USITC) publishes the official Harmonised Tariff Schedule (HTS) on its website (https://hts.usitc.gov). Online HS Code Finders: Many commercial websites and platforms offer HS code lookup tools. These tools typically allow you to search by product description or keywords. Examples include platforms from logistics companies, trade data providers (e.g., Trade Atlas, Freightos), and customs clearance service providers. Customs Brokers and Consultants: If you have complex products or are unsure, it’s advisable to consult a customs broker or trade consultant. These professionals have specialised knowledge in product classification. Artificial Intelligence Tools: Emerging AI tools can assist with HS code classification by analysing detailed product descriptions. However, verification is still recommended to ensure accuracy. U.S. Customs and Border Protection Online Ruling Search System (CROSS): The U.S. Customs and Border Protection database contains binding rulings for specific products and is a valuable resource for complex classifications.Staying Up-to-Date: The Importance of Updates
The Harmonised System is continually evolving. The World Customs Organisation (WCO) reviews and revises the Harmonised System approximately every five years to accommodate changes in technology, trade patterns, and the emergence of new products. The most recent major revision by the WCO took effect on January 1, 2022, and countries have since incorporated these changes into their national tariff schedules. For example, the United States Harmonised Tariff Schedule (HTS) is regularly updated to reflect these changes from the WCO and other domestic legislative actions. The 2025 HTS is the current version that U.S. importers must use. For traders, always use the latest version of the relevant tariff schedule to stay compliant.Frequently Asked Questions About HS Codes

The most recent major update, HS 2022, took effect on January 1, 2022, ensuring the system remains relevant and accurate in a changing global marketplace.
Are HS Codes the Same in Every Country?
The first six digits of an HS code are standardized internationally. They should be consistent across all countries that are members of the World Customs Organization (WCO) and use the Harmonized System. However, countries may add digits (national subdivisions) to the six-digit HS code for their tariff classification or statistical purposes. This means an 8- or 10-digit code may vary from country to country.
