What are the various factors used in classifying commodities for tariff purposes?

Commodities are classified for tariff purposes based on several factors, including their physical characteristics, intended use, and production methods. Additionally, the Harmonized System (HS) codes are utilized, which categorize goods according to specific criteria such as material composition and functionality. Tariff classification also considers the origin of the goods and any applicable trade agreements or regulations. Lastly, factors like market demand and historical trade patterns may influence classification decisions.
