What is an HS code and how do I find the right one?

An HS code is a standard number that classifies a product for customs. The first six digits are the international Harmonized System, shared by most countries. For US imports the code is extended into a longer Harmonized Tariff Schedule (HTS) number, and that number decides your duty rate. To find yours, describe the product precisely, search the USITC tariff database, and check CBP's ruling database for similar goods.

Why the code matters

The code determines the duty rate, and whether extra tariffs, quotas or agency rules apply. It goes on customs paperwork, so a wrong code can mean overpaying, delays or penalties. CBP's duty-rate page notes that the HTS covers nearly every item and that CBP, not the importer, makes the final determination of the correct duty rate.

HS, HTS and Schedule B

• HS (Harmonized System). The international six-digit system.
• HTS (Harmonized Tariff Schedule). The US version used for imports, published by the US International Trade Commission. It starts with the six HS digits and adds more for US duty rates and statistics.
• Schedule B. The system used for exports, run by the Census Bureau.

For importing into the US, you want the HTS number. Suppliers often quote only the six-digit HS code, which is a start but not the full US code.

How to find the right code

1. Write down the product facts. Material, how it is made, what it does, how it is sold. A "backpack" and a "laptop bag" can fall under different headings.
2. Search the USITC HTS. Search by keyword and work down the chapters and headings. Read the notes at the start of each section, because they say what is included and excluded.
3. Ask your supplier what code they use, then verify it yourself. Treat it as a hint.
4. Search CBP's CROSS database. It holds published rulings, where CBP has classified real products. Similar goods are a good guide.
5. Ask a customs broker. Brokers classify goods every day and file the entry.
6. For a firm answer, request a binding ruling. CBP issues binding advance rulings on matters including tariff classification. It takes time, so use it for higher-value or repeat products.

Common mistakes

• Picking a code by name only. Product names are not headings.
• Using the supplier's code without checking it. A supplier's code may be for their own country's system, not the US one.
• Skipping the section notes. They control what fits where.
• Classifying a bundle as one item. Sets and kits have their own rules.
• Not reviewing codes when a product changes. Material or function changes can change classification.

How the code ties into cost

Once you have the HTS number, look up the duty rate and any additional duties for your country of origin, then put them in your landed cost. The USITC database gives an approximate rate, and CBP warns the actual rate may differ from what you expect, so confirm with a broker for large orders.

Where Shield fits

Shield doesn't classify goods, and a code is not something a payments provider decides. What Shield can do is the money side of importing: US accounts, business credit cards and supplier payments, including to China and Hong Kong, for importers, exporters and wholesalers. Keeping the invoice, the HTS number and the payment record together makes later reviews easier.

FAQ

Is an HS code the same as an HTS code? The first six digits are shared. The US HTS is longer and is the one that sets US duty rates.

Who decides the final code? CBP makes the final determination. If you are unsure, ask a customs broker or request a binding ruling.

Can two products with similar names have different codes? Yes. Materials and use often decide it.
