HS codes for China imports: how to find and use them

What an HS code actually is

The Harmonized System is an international classification framework used by over 200 countries. Every tradeable product maps to a 6-digit HS code. Countries then extend that with additional digits for their national tariff schedules.

In the US, the full code is 10 digits and is called the HTS (Harmonized Tariff Schedule) number. The first 6 digits are the universal HS code shared across countries; the last 4 are US-specific and determine the exact duty rate and any additional tariff columns that apply, including Section 301 and executive-order tariffs on goods from China.

The duty rate is tied to the 10-digit HTS number, not to a product description. Two items that look similar can have different codes and very different duty rates.

How to find your HTS code

The authoritative source is the US International Trade Commission (USITC) tariff database at hts.usitc.gov. You can search by keyword or browse the schedule by section and chapter.

• Start with the product's material: goods are organized first by what they are made of (textiles, metals, plastics, electronics), then by function.
• Read the chapter notes and section notes, not just the heading descriptions. A product that looks like it fits one heading may be excluded by a note.
• Use the most specific applicable subheading. A vague high-level code is a misclassification flag.

If you are unsure between two codes, look at the duty rates for both and the tariff columns for China. The difference can be significant.

Common misclassification traps

Misclassification is the most common customs problem for small importers. It is almost always unintentional, but customs does not distinguish between innocent and deliberate errors.

• Using a supplier-suggested code without verifying it. Suppliers often give codes based on what left their country, not what enters yours.
• Using a 6-digit HS code instead of the full 10-digit HTS number. Truncated codes are not valid for US entry.
• Choosing a code based on the product name rather than its material, construction, or function.
• Using a code from a prior shipment without checking whether it changed. HTS codes are revised periodically.

Confirming your code before you ship

For a product you import regularly, a binding ruling from US Customs and Border Protection (CBP) gives you certainty. CBP will classify the product and that ruling is legally binding for future entries. The process takes several months, so it is better suited to ongoing programs than one-off shipments.

For a one-off or first shipment, a licensed customs broker can review your product and confirm the correct code. That is the faster and more common path for small importers.

Either way, confirm before the goods ship, not after they arrive. A hold at the port is far more expensive than getting the code right in advance.
