HS Code Search — Harmonized System Lookup

What Is an HS Code?

The HS Code (Harmonized Commodity Description and Coding System) is an internationally standardised system for classifying traded goods. It was developed and is maintained by the World Customs Organization (WCO), headquartered in Brussels, Belgium. Introduced in 1988, the Harmonized System has become the global standard — more than 200 countries and customs territories use it as the foundation for their national tariff schedules.

An HS Code consists of 6 digits and classifies goods hierarchically: from broad categories (sections, chapters) down to increasingly specific descriptions (headings, subheadings). The system encompasses 21 sections, 97 chapters, and approximately 5,000 commodity groups, covering virtually every product traded internationally — from raw agricultural commodities to the most advanced electronics.

The key advantage of the Harmonized System is its universality — the same first 6 digits identify the same product regardless of the country. An exporter in Germany and an importer in the United States, China, or Japan all use the same tariff language. For e-commerce sellers on platforms like Amazon, eBay, and Shopify, the HS Code is indispensable for calculating landed costs, preparing customs declarations, and ensuring that international shipments clear customs without delays.

HS Code Structure — How the 6 Digits Work

The HS Code has a hierarchical structure that narrows from broad product categories to specific items. Below is an example breakdown using code 6912.00 (ceramic tableware):

The first 2 digits identify the chapter (e.g., 69 = Ceramic products; 85 = Electrical machinery and equipment). Digits 3-4 form the heading, and digits 5-6 form the subheading. International standardisation ends at this 6-digit level — any additional digits are added by individual countries or customs unions (e.g., CN digits 7-8 in the EU, HTS digits 7-10 in the US).

HS vs HTS vs CN — Code Systems at a Glance

The 6-digit HS Code is the starting point for all national and regional tariff systems. Each country or customs union extends the HS with additional digits for its own regulatory needs. This is where confusion often arises for e-commerce sellers and importers who deal with multiple markets:

Regardless of how many digits a national system uses, the first 6 are always identical — that is the HS Code, the universal language of international trade. For Amazon FBA sellers sourcing from China, this means the 6-digit HS code on your supplier's invoice is valid globally, but you need the full national extension (HTS for US, CN/TARIC for EU) for your customs declaration.

HS Codes for E-Commerce Sellers and Amazon FBA

If you sell products online through Amazon FBA, eBay, Etsy, or your own Shopify store and source goods from overseas suppliers, HS codes directly impact your business in several critical ways:

• Landed cost calculation — the HS code determines the duty rate, which directly affects your product's landed cost and therefore your profit margins. A miscalculated duty rate of even 5% can eliminate your margin on competitive products.
• Customs clearance speed — an incorrect or missing HS code on your commercial invoice is the number one reason for customs delays. Your Amazon FBA shipment sitting in customs for an extra week means missed sales and potential stockouts.
• Multi-market compliance — if you sell on Amazon.com (US), Amazon.co.uk (UK), and Amazon.de (EU), you need the correct national extension for each market: HTS for the US, UK Commodity Code for the UK, and CN/TARIC for the EU.
• Supplier communication — sharing the correct HS code with your Chinese or other overseas supplier ensures they declare the right code on the export side, avoiding discrepancies that trigger customs scrutiny.

Celna24's AI-Powered Search is particularly useful for e-commerce sellers who may not be customs experts. Simply describe your product (e.g., “ceramic coffee mug with handle, dishwasher safe”) and our AI will suggest the most relevant HS/CN codes based on real BTI rulings.

How to Find Your HS Code

Finding the correct HS Code requires an accurate description of your product — its material composition, function, intended use, and physical form. On Celna24.com you can use several tools:

If you are uncertain about the correct classification, you can apply for a Binding Tariff Information (BTI) ruling from your national customs authority. A BTI decision is legally binding for 3 years across the EU, giving you certainty about the applicable code, duty rate, and regulatory requirements. For high-volume Amazon FBA sellers, a BTI can save thousands in potential reclassification costs.

HS Code Examples — Popular E-Commerce Products

Below are HS code examples for products commonly sold online, along with their approximate EU duty rates. These illustrate how duty rates can vary dramatically across product categories:

Note: actual duty rates may vary depending on the country of origin (preferential trade agreements, GSP, free trade agreements). Running shoes at 16.9% illustrate how non-tech consumer goods can carry significant duties that directly impact your pricing strategy. Check the latest rates in the Customs Tariff.

Common HS Code Mistakes to Avoid

Based on real customs practice and BTI decisions, these are the mistakes that e-commerce sellers and importers make most often when working with HS codes:

• Trusting the supplier's code blindly — Chinese suppliers frequently provide HS codes that minimise export duties in China rather than correctly classify the product for the destination country. Always verify independently.
• Using the US HTS code for EU imports — while the first 6 digits are the same globally, extensions differ. An HTS code is not valid for an EU customs declaration and vice versa.
• Classifying by product name instead of composition— “power bank” or “fitness tracker” are not HS headings. Classification depends on material, function, and intended use.
• Ignoring annual updates — the Combined Nomenclature changes every year. A code that was valid last year may have been split, merged, or deleted in the current edition.
