HS Code Finder: Find the Right Customs Code Before You Ship

An HS code is an internationally standardised number used to classify a product for customs purposes. The first six digits are the same in more than 200 countries; from there, individual countries and regions — including the EU with its TARIC code — add further digits for their own tariff and statistics needs.

Our HS Code Finder above suggests a starting code from a plain description of your product; the sections below explain how the code is structured, how to find it yourself using official databases, and where to go if you’d rather get a binding answer or estimate the import duty it triggers.

The Harmonized System (HS) is a standardised numerical method of classifying traded products, maintained by the World Customs Organization. Every product moving across a border — from a T-shirt to an industrial pump — has a corresponding HS code, and customs authorities use it for three things: calculating the import duty owed, checking whether the goods are subject to specific trade rules or restrictions, and assessing risk.

Get the code wrong, and the consequences follow directly: the wrong duty rate may be applied, the shipment can be delayed for reclassification, or — in the case of a deliberately incorrect code — you may face penalties. That makes the HS code one of the first things to get right, before duty, VAT or clearance costs are even calculated. For a full breakdown of the customs guide and how these pieces fit together, see our customs overview; the shipping glossary also has a short definition entry.

The terms are often used interchangeably, but they describe three different levels of precision.

The Harmonized System code is the globally uniform standard: six digits, defined and maintained by the World Customs Organization, and used in more than 200 countries. This is the level at which products are consistently classified worldwide.

Countries extend the six-digit HS code with additional digits for their own tariff and statistics purposes. In the EU, export declarations use an eight-digit code; import declarations use a ten- or eleven-digit code, known as the TARIC code. The extra digits determine the concrete duty rate, taxes and any specific regulations that apply.

The EU’s own ten-digit extension (the eight-digit code plus two further digits), which captures EU-specific measures such as anti-dumping duties, quotas or preferential rates. It’s the level of detail EU customs authorities actually check against when goods are imported — see the German customs tariff guidance for how this works in practice.

In short: the HS code is the worldwide foundation, the commodity code adds a country’s own detail, and the TARIC code is the EU’s specific ten-digit version of that detail. Getting the code right is only half the picture — who actually pays the duty and VAT it triggers, and who is responsible for customs formalities, is a separate question, settled by the Incoterms agreed for the shipment.

Take 6109.10 — cotton T-shirts — as an example:

Import duty on shipments to the USA has changed considerably across many product categories, in some cases sharply. And since Brexit, shipping to the UK brings its own customs requirements. An imprecise or incorrect code can mean:

• Describe the product precisely. Include what it’s made of, what it’s used for and how it’s presented (loose, packaged, as a set). A vague description is the most common reason an HS code ends up wrong — see the mistakes below.
• Try the HS Code Finder above. Type in your product description and get a suggested starting code in seconds — useful as a first orientation before checking the official databases.
• Confirm the code in an official tariff database. For the EU, the TARIC database lets you search by product description or browse by category and returns the applicable customs tariff number for your destination market — the authoritative source for any classification you’ll actually declare.
• Check your supplier’s documentation. The code is often already stated on the commercial invoice, sometimes labelled “customs code“. As the shipper, you remain responsible for the correct classification even if you’re relying on a supplier’s figure — always verify it independently.
• Save confirmed codes for repeat shipments. If you ship the same product line regularly, record the confirmed code once rather than reclassifying it from scratch every time — LetMeShip stores codes against your shipment history for exactly this reason.
• If in doubt, ask. For anything unclear, our support team can help you work through the classification, or you can apply for a Binding Tariff Information (BTI) ruling (see below) for full legal certainty.

• Vague product descriptions. “Plastic parts” or “electronic device” isn’t specific enough — the classification depends on exact material, function and composition.
• Outdated codes. HS codes are revised roughly every five years by the World Customs Organization; a code that was correct three revisions ago may no longer apply.
• Leaving the code out entirely. A missing HS code is one of the most common causes of delays at customs — the shipment is held until it can be classified manually.
• Deliberately misclassifying goods to reduce duty. Beyond the ethical issue, this can result in penalties, back payments and repeated customs scrutiny of future shipments.

If you need full legal certainty rather than a starting suggestion, you can apply for Binding Tariff Information (BTI) — an official, written ruling from a customs authority confirming the correct HS code for your specific product. A BTI is issued through the EU Customs Trader Portal, is valid across the entire EU, and typically holds for around three years. It’s a formal process best suited to products you ship repeatedly at volume or where the classification is genuinely ambiguous — not something needed for every shipment.

Once you have a confirmed HS code, the next question is usually what it will cost to bring the goods across the border. Our import duty calculator uses the same kind of plain-description input to estimate import duty, import VAT and likely customs clearance costs — the code you’ve just found is exactly what that estimate is based on. From there, you can compare shipping costs across carriers and book your shipment with the customs paperwork already in hand.

An HS code suggestion is a starting point, not a substitute for judgement on genuinely ambiguous products. If you’re unsure — or shipping something classification-sensitive at volume — our support team can talk it through with you directly. That’s consistent with how LetMeShip works more broadly: personal service throughout the shipping process, not just at the point of booking.
