Structure

The HS is organized logically by economic activity or component material. For example, animals and animal products are found in one section of the HS, while machinery and mechanical appliances are found in another. The HS is organized into 21 Sections, which are subdivided into 96 Chapters (Chapters 1 to 97 with Chapter 77 reserved for potential future use by the HS). The 96 HS Chapters are further subdivided into 1,228 headings and 5,612 subheadings in the current 2022 edition of the HS.
Section and Chapter titles describe broad categories of goods, while headings and subheadings describe products in more detail. Generally, HS Sections and Chapters are arranged in order of a product's degree of manufacture or in terms of its technological complexity. Natural commodities, such as live animals and vegetables, for example, are described in the early Sections of the HS, whereas more evolved goods such as machinery and precision instruments are described in later Sections. Chapters within the individual Sections are also usually organized in order of complexity or degree of manufacture. For example, within Section X (''Pulp of wood or of other fibrous cellulosic material; Recovered (waste and scrap) paper or paperboard; Paper and paperboard and articles thereof''), Chapter 47 provides for ''pulp of wood or of other fibrous cellulosic materials'', whereas Chapter 49 covers ''printed books, newspapers, and other printed matter''. Finally, the headings within individual Chapters follow a similar order. For example, the first heading in Chapter 50 (''Silk'') provides for ''silk worm cocoons'' while articles made of silk are covered by the Chapter's later headings.
The HS code consists of 6-digits. The first two digits designate the Chapter wherein headings and subheadings appear. The second two digits designate the position of the heading in the Chapter. The last two digits designate the position of the subheading in the heading. HS code 1006.30, for example, indicates Chapter 10 (''Cereals''), heading 10.06 (''Rice''), and subheading 1006.30 (''Semi-milled or wholly milled rice, whether or not polished or glazed'').
In addition to the HS codes and commodity descriptions, each Section and Chapter of the HS is prefaced by Legal Notes, which are designed to clarify the proper classification of goods.

at the 8-digit "tariff code" level. Statistical suffixes are often added to the 8-digit tariff code for a total of 10 digits. If the number of digits are more than 6, additional digits are called as the national subdivision.
Chapter 77 is reserved for future use by the HS. Chapters 98 and 99 are reserved for domestic use for the Contracting Parties to the HS Convention.
Since its creation, the HS has undergone several revisions to reflect changes in trade. These revisions eliminate some headings and subheadings describing commodities with low volume of trade and create new headings and subheadings that address new needs, for example, to reflect technological advancements or monitor goods posing environmental concerns. The current edition of the HS became effective on 1 January 2022.
Classification
The process of assigning HS codes is known as "HS Classification". All

General Rules for the Interpretation of the Harmonized System ("GRI")'' that must be applied in strict order. HS codes can be determined by a variety of factors including a product's composition, its form and its function. An example of a product classified according to its form would be whole

es. The classification will also change depending on whether the potatoes are fresh or
frozen. Fresh potatoes are classified, under heading 07.01 (''Potatoes, fresh or chilled''), more specifically under subheading 0701.90 (''Other''), while frozen potatoes are classified, under heading 07.10 (''Vegetables (uncooked or cooked by steaming or boiling in water), frozen''), more specifically under subheading 0710.10 (''Potatoes'').

If the CO detector does not capture and display gas measurements, then it is properly classified under subheading 8531.10 (''Burglar or fire alarms and similar apparatus''), under heading 85.31 (''Electric sound or visual signaling apparatus (for example, bells, sirens, indicator panels, burglar or fire alarms), other than those of heading 85.12 or 85.30'').
Although every product and every part of every product is classifiable in the HS, very few are explicitly described in the HS Nomenclature. Any product for which there is no explicit description can be classified under a "residual" or "basket" heading or subheading, which provide for ''Other'' goods. Residual codes normally occur last in numerical order under their related headings and subheadings. An example of a product classified under a residual heading is a live

Challenges in classification for companies

automotive parts, for example, are not classified under heading 87.08, which provides for ''Parts and accessories of the

s of headings 87.01 to 87.05''. For example,
automotive seats are classified as articles of furniture under heading 94.01, which provides for ''Seats (other than those of heading 94.02), whether or not convertible into beds, and parts thereof'', and more specifically under subheading 9401.20, which provides for ''Seats of a kind used for motor vehicles''.
In many jurisdictions,
traders alone bear the
legal responsibility to accurately classify their goods. However, due to a lack of familiarity with the rules of HS classification traders may inadvertently determine erroneous HS codes for their commodities. Depending on the severity of the infraction, incorrect classification can result in the imposition of non-compliance penalties, border delays or seizures, or denial of import privileges.
There are multiple resources available to traders to assist in properly classifying their goods including the following.

HS code determination guidesand other references to classify their traded commodities. These could include local databases published by authorities in other countries. However, such databases are not valid globally.
Many Customs authorities around the world allow traders to apply for an advanced HS classification ruling. Such rulings are legally binding in the countries where they are issued and give certainty to the trader. Provided the information supplied in the request was truthful and valid, they may also provide legal protection to the trader following the ruling if there are future questions on the classification of the goods.
