Chapter 73 covers articles of iron or steel, including tubes, hollow profiles, fittings, structural members, containers, cables, etc. This chapter ranges from 7301 to 7326 and involves iron or steel articles produced by casting, forging, welding, cold forming, and other processes. 7306 is the tube heading within this chapter, specifically for circular or non-circular hollow tubes made by welding or similar methods. Heading 7306 covers other tubes, pipes and hollow profiles of iron or steel, such as tubes closed by welding, riveting or similar methods, including circular and non-circular cross-sections. However, it excludes seamless tubes (7304), cast tubes (7303), and tube fittings made into specific articles (such as 7307 pipe fittings). 730630 is a subheading under this heading, specifically referring to galvanized welded tubes. First 2 digits 73: Chapter 73, articles of iron or steel. Digits 3-4, 06: Heading 7306, other tubes, pipes and hollow profiles of iron or steel (for example, closed by welding, riveting or similar methods), excluding seamless tubes and cast tubes. Digits 5-6, 30: Subheading 730630, other welded tubes of circular cross-section, galvanized or zinc-coated. Note: 730630 covers only galvanized welded tubes of circular cross-section; galvanized welded tubes of non-circular cross-section fall under other subheadings of 7306. The product is a galvanized welded tube, closed by welding, with a circular cross-section and a galvanized surface. It meets the description of heading 7306, and because it is galvanized and has a circular cross-section, it is classified under 730630. If it were seamless, it would be classified under 7304; if it had a non-circular cross-section, it would fall under other subheadings of 7306; if it were a pipe fitting, it would be classified under 7307.

🎯 Classification Logic
Core basis for classification: 1) Material is iron or steel; 2) The tube is made by welding; 3) Cross-section is circular; 4) Surface is galvanized. Meeting all the above conditions classifies it under 730630. If seamless, it is classified under 7304; if non-circular welded tube, it falls under other subheadings of 7306; if pipe fitting, it is classified under 7307. 7304 Seamless steel tubes: Seamless tubes are made by piercing and rolling processes without welds; welded tubes have welds and are classified under 7306. 7306.50 Other welded tubes of circular cross-section (not galvanized): 7306.50 is for non-galvanized circular welded tubes, while 730630 is for galvanized ones. 7306.90 Welded tubes of non-circular cross-section: 7306.90 covers square, rectangular, and other non-circular cross-sections, while 730630 is only circular. 7307 Pipe fittings: 7307 is for pipe joints, elbows, and other fittings, not the tubes themselves. Is it made of iron or steel? Is it made by welding? Is the cross-section circular? Is it galvanized? Is it not a seamless tube or cast tube?
