HS (Harmonized System) code is an internationally standardized product classification system developed by the World Customs Organization (WCO), adopted by over 200 countries. It consists of 6 digits globally, with countries extending to 10 digits (e.g., US HTS 10-digit, UK Commodity Code 10-digit, China HS 10-digit).

How accurate is AI HS code classification?

HSBot is built on official customs policy and real customs data. For common products, classification accuracy exceeds 95%. AI results are for reference only—actual declarations should be verified with customs authorities. Combining product details (material, usage, composition) improves accuracy.

What countries does HSBot support?

HSBot currently supports US HTS codes and UK tariff codes (import classification) and China HS codes (export classification), covering the most common China-US and China-UK trade scenarios. More countries including EU, Japan, Vietnam, and Mexico are coming soon.

What is Section 232 tariff?

Section 232 tariff is an additional US import duty on steel, aluminum, and copper products based on national security grounds. HSBot automatically calculates applicable Section 232 rates based on HS code prefixes and exporting country.

What is Section 301 tariff?

Section 301 tariff is an additional US import duty on certain products from China, in response to trade practices. HSBot automatically identifies applicable Section 301 rates and checks for tariff exclusions.

How do I find the correct EU HS code?

The EU uses TARIC, its integrated tariff database. You search by product description or by the known 6-digit HS, then read the EU's 8- or 10-digit code and any applicable measures (duty, VAT, anti-dumping). The first 6 digits match the international HS; the EU adds digits and measures on top.

How is a Japan import tariff calculated?

Japan generally assesses customs duty on the CIF value (cost + insurance + freight to the Japanese port), unlike the U.S. which uses FOB. On top of duty, Japan adds a consumption tax on the duty-inclusive value. The rate itself is found in Japan's tariff schedule by the 9-digit statistical code derived from the HS.

Is the HS code the same in the EU, US, and Japan?

The first 6 digits are the same everywhere — that is the international HS coordinated through the WCO. The digits after that differ: the U.S. uses a 10-digit HTS, the EU uses an 8-/10-digit TARIC code, and Japan uses a 9-digit statistical code. Same product family, country-specific suffixes.

When will HSBot support the EU and Japan?

HSBot already covers China, the United States, and the United Kingdom, with the EU and Japan in active expansion. Because the 6-digit HS is shared internationally, HSBot's description-to-code engine already works from the common base; country-specific 10-digit (or 9-digit) suffixes follow as each schedule comes online. The current supported list and rollout status are published in the Data version & sources section of the Help Center (/en/help#data-version).

How to Look Up EU HS Codes and Calculate Japan Tariffs (Importer's Guide)

Short answer: The EU and Japan each run their own classification and duty system on top of the same international HS backbone. You find the EU code in TARIC and calculate a Japan tariff on a CIF base plus consumption tax. The good news: the first 6 digits of the HS code are identical worldwide, so once you know the international base, you only re-map the country-specific suffix for each market.

The one fact that saves you everywhere: HS is international

No matter the destination, the first 6 digits of an HS code are set by the WCO and shared by every country:

Market	Code structure	Base value for duty
United States	10-digit HTS	FOB
European Union	8-/10-digit TARIC	CIF (often)
Japan	9-digit statistical code	CIF
China / UK	national schedule	varies

So "what is my product" is answered once at the 6-digit level; "what digits and what rate does this country attach" is the per-market step.

Finding the EU HS code in TARIC

TARIC is the EU's integrated tariff. The practical path:

Start from the 6-digit HS if you already have it, or search TARIC by product description.
Read the EU's 8-/10-digit code — the EU adds digits for statistical tracking and measures.
Check the measures attached to the code — not just the duty rate, but VAT, suspensions, quotas, and any anti-dumping or countervailing duty. The measure, not the heading, is what changes your landed cost.
Confirm the code is current — like the U.S., EU codes are revised, so verify against the live TARIC before a shipment.

The EU also distinguishes duty methods (ad valorem, specific, compound), so the rate you see may not be a simple percentage.

Calculating a Japan import tariff

Japan's mechanics differ from the U.S. in two ways that catch new importers:

Base value is CIF, not FOB. Japan assesses customs duty on cost + insurance + freight to the Japanese port. If you are used to U.S. FOB-based math, your Japan number will look different even for the same goods.
Consumption tax stacks on top. After duty is computed, Japan adds a consumption tax on the duty-inclusive value. The "tariff" people quote is rarely the full landed-cost story.

The rate itself comes from Japan's tariff schedule, keyed to the 9-digit statistical code derived from the HS. As with the EU, verify the code against the current schedule — Japan revises its schedule too.

Why this matters before you expand

Expanding from the U.S. (or China/UK) into the EU and Japan is mostly a suffix-and-base problem, not a re-classification problem:

You keep the 6-digit HS you already know.
You re-map to the EU 8-/10-digit TARIC code and the Japan 9-digit code.
You switch the duty base (CIF for EU/Japan vs FOB for the U.S.) and add the local consumption tax / VAT.

That is far less work than starting cold — but only if your tooling resolves the country-specific suffix instead of handing you one global number.

Where HSBot fits

HSBot already covers China, the United States, and the United Kingdom, and is expanding into the EU and Japan. Because the engine resolves codes from a product description on the shared 6-digit HS base, the international part works everywhere; the country-specific 10-digit (or 9-digit) suffix follows as each schedule comes online. For the U.S. side of the same workflow, see the US HTS code lookup guide and the UK tariff calculation guide. Current supported markets and rollout status are always in the Help Center's Data version & sources.

Quick takeaways

6-digit HS = same worldwide; only the suffix and the duty base differ by country.
EU → TARIC, watch the attached measures (VAT, anti-dumping), not just the rate.
Japan → CIF base + consumption tax; the quoted "tariff" is not the full landed cost.
Verify each market's code against its live schedule before shipping.
