HS Code Lookup: How to Find the Right Tariff Code for Your China Import (2026)

An HS code (Harmonized System code) is a standardized numerical code used worldwide to classify traded products. Every product you import must be assigned an HS code, which determines the duty rate (tax) you pay at customs, the regulations that apply (safety, labeling, restrictions), and the trade statistics your import contributes to.

Getting the HS code wrong can be expensive:

• Overpaying duties: Classifying a product under a higher-duty code means paying more tax than necessary on every shipment
• Underpaying duties (worse): Customs can audit past imports, charge back duties owed plus penalties, and flag your account for enhanced inspection on future shipments
• Shipment delays: An incorrect HS code can trigger customs holds while they reclassify your goods
• Regulatory issues: Some HS codes require specific permits, certifications, or are subject to anti-dumping duties or trade restrictions

HS codes follow a hierarchical structure:

The first 6 digits are universal — they mean the same thing in every country. Digits 7-10 are country-specific. When your Chinese supplier gives you an HS code, the first 6 digits are directly usable; you need to look up the full 8-10 digit code for your importing country.

1. Ask Your Chinese Supplier

Chinese exporters deal with HS codes daily. Ask: "What HS code do you use when exporting this product?" They'll give you the Chinese 8-digit code (HS编码). The first 6 digits are your starting point — then look up the corresponding code in your country's tariff schedule.

Caution: Some suppliers intentionally suggest lower-duty HS codes to make their quote look cheaper. Always verify independently.

2. Use Your Country's Tariff Database

• US: USITC Harmonized Tariff Schedule (hts.usitc.gov) — search by keyword or browse by chapter
• EU: TARIC database (ec.europa.eu/taxation_customs/dds2/taric) — includes duty rates and regulations
• UK: UK Trade Tariff (trade-tariff.service.gov.uk)
• Canada: CBSA Customs Tariff (cbsa-asfc.gc.ca)

3. Use a Customs Broker

If you're importing regularly, your customs broker classifies products as part of their service. They have expertise in borderline cases where a product could fall under multiple codes. For first-time importers, this is the safest option — misclassification penalties far exceed the broker's fee.

4. Request a Binding Ruling

In the US, you can request a binding ruling from US Customs (CBP) that officially classifies your product. This takes 30-90 days but provides legal certainty. Useful for complex products or those subject to anti-dumping duties where classification has significant financial impact.

Mistake 1: Using the supplier's Chinese HS code directly. The first 6 digits transfer, but digits 7-10 differ between countries. A product classified as 8501.10.40 in China may be 8501.10.60 in the US. Always look up the full code in your country's tariff schedule.

Mistake 2: Classifying by intended use instead of material/construction. HS codes are based on what a product is (material, construction, function), not what it's used for. A stainless steel bottle is classified under stainless steel articles, regardless of whether it's used for water, coffee, or chemicals.

Mistake 3: Ignoring anti-dumping duties. Some product categories from China carry additional anti-dumping or countervailing duties on top of standard tariffs. Steel products, aluminum, solar panels, and certain chemicals are common examples. These can add 10-200%+ to your duty bill. Check the US ITC anti-dumping database before importing.

Mistake 4: Not checking for trade agreement benefits. Some products qualify for reduced or zero duties under trade agreements. While there's no US-China FTA, products that are substantially transformed in a third country before importing to the US may qualify under other agreements.

Before worrying about HS codes, make sure your supplier is legitimate. Use ExpoAlive to verify any Chinese manufacturer with government data. The most expensive import mistake isn't the wrong HS code — it's sending money to the wrong factory.
