What is a Harmonized System number?
The Harmonized Tariff System (HTS) is a universal classification system that is used to provide duty rates for virtually every item that exists. Every item that is exported is assigned a unique 10-digit identification code. Every 10 digit item is part of a series of progressively broader product categories.

For example, the harmonized system number for concentrated frozen apple juice is: 2009.70.0010.

The concentrated frozen apple juice is assigned a 10-digit identifier that is aggregated into a broader category assigned a 6-digit identifier described as apple juice (2009.70.).

The 6-digit identifier described as apple juice is aggregated into a broader category assigned a 4-digit identifier (2009) described as fruit juices and vegetable juices, etc.

The 4-digit identifier is further aggregated into a broader category assigned a 2-digit identifier (20) described as Preparations of Vegetables, Fruit, Nuts etc.

The first 6-digits of the classification number are universal, the last four may vary from country to country.

What is the difference between the Schedule B codes (for exports) and the Harmonized Tariff Schedule (HTS) codes (for imports)?

All of the imports and export codes used by the United States are based on the Harmonized Tariff System (HTS). The HTS assigns 6-digid codes for general categories. Countries which use the HTS are allowed to define commodities at a more detailed level than 6-digits, but all definitions must be within that 6-digit framework.

The U.S. defines products using 10-digit HTS codes. Exports codes (which the U.S. calls Schedule B) are administered by the U.S. Census Bureau. Import codes are administered by the U.S. International Trade Commission (USITC).

Why do I need a Harmonized System/Schedule B Number?

In order to determine duty rates for each individual country you must first obtain the Schedule B/Harmonized System number. The Central and Eastern Europe Business Information Center (CEEBIC) can provide unofficial tariff rates for non-agricultural products for certain countries as well as contact information for foreign Customs authorities. Certain express carriers may also require you to list the Schedule B number on their airway bill or the commercial invoice.

How do I determine my HS or Schedule B Number?

To obtain your Schedule B number, visit the U.S. Census Bureau's web site at http://www.census.gov/foreign-trade/www. The Schedule B is published on this website, and ou can classify your own product through a keyword search.
