&&Section 10 of the Customs Tariff directs that classification of imported goods shall be determined in accordance with the General Rules for the Interpretation of the Harmonized System and the Canadian Rules set out in the schedule. Section 11 of the Customs Tariff states that in interpreting the headings and subheadings, regard shall be had to the World Customs Organization's (WCO) Compendium of Classification Opinions and Explanatory Notes to the Harmonized Commodity Description and Coding System (HS).&&&&General Interpretative Rule 1 (GIR 1) directs that titles of Sections, Chapters and sub-Chapters are provided for ease of reference only. For legal purposes, classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. Similarly, General Interpretative Rule 6 (GIR 6) directs that classification shall be determined according to the terms of those subheadings and any related Subheading Notes.&&&&In your application for an advance ruling, you suggested tariff classification number 7307.02.00.00. This tariff classification is incorrect, as this tariff classification number does not exist in the Customs Tariff 2026.&&&&Following GIR 1, the goods are classified under heading 73.07, which covers tube or pipe fittings (for example, sleeves), of iron or steel.&&&&Explanatory Notes to heading 73.07 indicate that these fittings are primarily used for connecting the bores of two tubes, connecting a tube to another apparatus, or closing a tube aperture.&&&&Chapter Note 1(d) applies throughout the nomenclature. As the goods do not meet the definition of stainless steel and are not threaded, they are properly classified under tariff item 7307.99.00 as “Other.”
