Harmonized System Classification

Start with the system

The Harmonized System Classification page brings together resources on identifying goods, classification rules and tariff questions. Begin with the mind map titled Harmonized System for an overview of the system. It introduces the classification of goods through codes and provides a starting point before you look at individual chapters or questions.

Next, explore the map on the goods identification process. It suggests identifying the goods fully and reading the section and chapter notes. Use it to organize the steps you want to follow when approaching a classification question.

Explore chapters and product details

The page includes maps on raw hides, skins and leather. One highlights material excluded from the chapter, including parings and birdskins. Another sets the chapter within a wider section covering leather, furskins and related articles. Compare the maps to see how a chapter description and its exclusions can guide your reading.

A separate map looks at product details such as the product name, commercial name and presentation. These details offer a way to think about what you need to identify before working through a classification exercise.

Put the maps to work with quizzes

After studying the maps, try HTS practice questions. Its questions include comparisons between US and Canadian tariff schedules and a question about a general duty rate. Use the maps to revisit goods identification when a question is difficult, then return to the quiz.

The HTS quiz also introduces explanatory notes for the Harmonized Tariff Schedule. The flashcard deck General Rules of Interpretation offers another format for studying alongside the maps and quizzes.

Place the topic in context
