A Two-Pass Harmonized Tariff Schedule Classification system and method is disclosed using an integrated Trade Compliance System (TCS). A classification analyst may preliminarily classify each product by comparing information about each product with information concerning HTS codes. The analyst may store these classifications in a repository in the TCS database. Subsequently, the information in the repository input by the analyst may be reviewed during a second pass by other personnel. The other personnel can review the information in the database for accuracy, taking into account other bases for classification.
