How to Find the Right HS Code for Products Imported from China

Every shipment you import from China is declared under a tariff classification code, and that code decides your duty rate, which trade measures apply, and sometimes whether you need a license. Getting it wrong can mean overpaying, underpaying and facing penalties, or having goods held at the border. This guide explains how the codes are built and walks through classifying a product with the official tools, so you can check what your supplier or forwarder puts on the paperwork.

What an HS code is#

An HS code is a product classification number from the Harmonized System, an international nomenclature maintained by the World Customs Organization (WCO). According to the WCO, more than 200 countries and economies use it, covering about 98% of world merchandise trade.

The system is organized from broad to specific:

The WCO updates the system every five to six years. The current edition is HS 2022, and the HS 2028 edition enters into force on 1 January 2028. The WCO says it contains 299 sets of amendments, resulting in 1,229 headings and 5,852 subheadings. If you import the same products for years, plan to re-check your codes when national tariffs switch over.

National extensions: HTS, CN, TARIC and the UK tariff#

Only the first six digits are the same everywhere. Each importing country adds its own digits, and duty rates live at that national level.

• United States: The Harmonized Tariff Schedule of the United States (HTSUS) is published by the US International Trade Commission (USITC) at hts.usitc.gov. The 8-digit line carries the duty rate; digits 9 and 10 are statistical suffixes, but the full 10-digit number is what you declare. US Customs and Border Protection (CBP) enforces classification and issues rulings.
• European Union: The Combined Nomenclature (CN) adds two digits to reach 8. TARIC, the EU's integrated tariff database, adds two more for 10 digits, covering measures such as anti-dumping duties and origin-specific rates.
• United Kingdom: GOV.UK explains that you classify goods to a 10-digit commodity code when importing and an 8-digit code when exporting, using the UK Trade Tariff service. Most duty rates are set at 8 digits, but digits 9 and 10 can change the duty or measures that apply.

This is why a supplier's "HS code" can be correct at six digits and still leave you with the wrong national line.

How to classify a product, step by step#

Classification is done by the importer against the legal text of the destination tariff, not by keyword guessing. Follow this order:

1. Describe the product precisely. Write down what it is made of (and the percentage of each material), what it does, how it works, who uses it, and how it is packed. Customs classifies what arrives, not the marketing name.
2. Find the likely chapter and heading. Use the search in your destination tariff: USITC HTS search for the US, the EU's TARIC consultation tool for the EU, or the UK Trade Tariff for Great Britain. Keyword results are only a lead.
3. Read the section and chapter notes. Notes often exclude goods from a chapter or define terms. Many classification errors come from skipping them.
4. Apply the General Rules of Interpretation (GRIs) to choose between competing headings (see the next section).
5. Work down to subheadings and national lines. Compare only lines at the same level (dash level) under the chosen heading, then go down to the full 8- or 10-digit code.
6. Check published rulings. Search CBP's Customs Rulings Online Search System (CROSS) at rulings.cbp.gov, or the EU's EBTI database, for decisions on similar products. They are strong evidence of how customs sees a product, although a ruling formally binds only for the goods it describes.
7. Record your reasoning and keep product specs, photos and the ruling references in your file. If customs questions the code later, this shows you took care.
8. Request a binding ruling if the product sits between two headings with different duty rates.

The General Rules of Interpretation, in plain terms#

The GRIs are six rules that form part of the Harmonized System itself and are reproduced in national tariffs, including the US HTS and the EU CN. They are applied in order:

• GRI 1: Classification is decided by the wording of the headings and the section and chapter notes. Section and chapter titles are for reference only. Most products are settled here.
• GRI 2: An incomplete, unfinished or unassembled article is classified as the finished article if it already has its essential character. References to a material also cover mixtures of that material with others.
• GRI 3: When two or more headings seem to fit, the most specific description wins (3a). If that does not decide it, mixtures, composite goods and retail sets are classified by the component that gives them their essential character (3b). If still tied, use the heading that comes last in numerical order (3c).
• GRI 4: Goods that fit no heading go under the heading for the goods they are most akin to.
• GRI 5: Fitted cases (camera bags, instrument cases) and normal packing are generally classified with the goods they hold.
• GRI 6: Subheadings are chosen by the same logic, comparing only subheadings at the same level.

Gift sets, multi-material products and "smart" versions of ordinary items are where GRI 3 matters most, and where importers and customs most often disagree.

Binding rulings: CBP, EU BTI and UK Advance Tariff Rulings#

A binding ruling is a written classification decision from customs that you can rely on for the goods described. It is the best protection when duty rates between candidate codes differ.

For the US, CBP's eRulings requirements list what to include: a full product description, materials, intended use, and photos or technical documents. Samples can be sent for requests that need them. Rulings are published in CROSS, which is why searching CROSS first is so useful.

EU guidance states that BTI decisions cannot be issued retroactively, and HMRC's guidance says applications cannot be made retrospectively, so apply before the imports you want covered.

Common mistakes, and why the supplier's code may be wrong#

Chinese suppliers often print a code on the commercial invoice. It may be accurate at six digits, but there are good reasons not to copy it:

• It is a Chinese export code. China, like every country, has its own national digits. The code on the supplier's paperwork was chosen for the Chinese export declaration, not for your country's tariff.
• It may be reused across products. A factory making many items may declare them under one familiar code, even when materials or functions differ.
• Classifying by name rather than by the rules. "Phone holder" or "organizer" is not a tariff description. Material, function and the chapter notes decide the heading.
• Ignoring essential character. A kit with a textile bag and metal tools is classified by the component that gives it its essential character, which may not be the one you think.
• Using out-of-date codes. Codes are split, merged and deleted when tariffs are revised, including at the HS 2028 changeover.
• Picking the lowest-duty code. Choosing a code because the rate is lower, without support in the rules, is misclassification and can lead to penalties.
• Forgetting extra duties. In the US and EU, the base rate can be only part of the story: country-specific duties or trade remedy measures may also apply to goods of Chinese origin. Check them in the official tariff for the date you import.

Where the HS code fits in your import planning#

The code feeds almost every other import calculation. Once you have it, you can estimate duty and import VAT for your landed cost calculation, check which product certifications such as CE, FCC, UKCA or CPC apply, and decide whether a DDP quote is plausible. An unusually low DDP price can be a sign that goods are being declared under a low-duty code.

If you ship to Amazon warehouses, the same code goes on your customs entry, so settle it before planning shipping to Amazon FBA. Also give your supplier the correct description for the packing list so the export and import documents describe the goods consistently.
