Having Trouble Searching for a Product?
There are several reasons that might explain why certain products are not found in the database:

Product Coverage—Currently, the database includes tariff and trade information for industrial products. Work is ongoing to add agricultural and textile products to future versions of the database. Industrial products are largely defined as products not covered under the WTO Agreement on Agriculture and the WTO Agreement on Textiles and Clothing.

Differing Tariff Nomenclature and HS Codes—The tariff information contained in this database includes the tariff nomenclature of the United States and its FTA partners at the time the individual agreements were negotiated. The tariff nomenclatures often contain technical descriptions of products rather than the more commonly known descriptions. For example, “cars” or “automobiles” are referred to as “motor vehicles” in the tariff schedules. Likewise, “computers” are referred to as “automatic data processing machines” in the tariff schedules. Furthermore, for some FTA partner countries, the nomenclature is in the official language of the partner country (French or Spanish).

Likewise, the tariff information contained in this database includes the Harmonized System (HS) codes (also referred to as tariff codes) of the United States and its FTA partners at the time the individual agreements were negotiated. Globally, countries harmonize their tariff schedules to the first six digits of the HS code. Beyond the first six digits, countries are permitted to assign codes in the manner they see fit. For this reason, often the code assigned by the United States for a particular product is not exactly the same as the code assigned by an FTA partner.

Please note, the database does not account for recent changes or updates to U.S. or FTA partner tariff nomenclatures. For the most up-to-date information on the U.S. Harmonized Tariff Schedule, consult the U.S. International Trade Commission. For up-to-date information on FTA partner’s tariff schedules, consult the customs authorities of the FTA partner.

Where to Find Proper HS Codes or Product Descriptions?
For exporters, Export.gov contains valuable information for determining the HS code for your product. If you are exporting, you will need to know the Schedule B number for your product. While these numbers are may not be identical to the HS code in the FTA partner country, exporters can use them to help approximate the HS code. The U.S. Census Bureau’s Schedule B Search Engine is a useful tool for determining where your product fits into the tariff nomenclature. However, please note, the ultimate classification of your good will be determined by the customs authority of the importing country.

For importers, the U.S. International Trade Commission’s HTS Online Reference Tool is a useful tool for helping to determine the U.S. tariff classification of your product. However, please note that the tariff classification for imports is ultimately determined by U.S. Customs and Border Protection.
