Analysis and Justification

Part number MG-C7 meets the terms of heading 90.26, which provides for "instruments and apparatus for measuring or checking the flow, level, pressure or other variables of liquids or gases". The Explanatory Notes (EN) to heading 90.26 further elaborate that this heading covers instruments and apparatus for measuring or checking the flow, level, pressure, kinetic energy or other process variables of liquids or gases. Subheading 9020.00 covers "Other breathing appliances and gas masks, excluding protective masks having neither mechanical parts nor replaceable filters", which does not describe the goods at issue.


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. 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) Explanatory Notes to the Harmonized Commodity Description and Coding System.

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 heading and any relative Section and 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 accordance with General Interpretative Rule 1 and 6, and with regard to the WCO Explanatory Notes to the Harmonized Commodity Description and Coding System, part number MG-C7, an oxygen flow regulator gauge, is classified in 9026.20.00.90 by GIR 1 and 6.
