Products classified under HTS 7306.69.70
Alloy Steel Welded Rectangular Tubing
Welded rectangular tubes made from alloy steel, with wall thickness under 4 mm and noncircular cross-section, used in structural frameworks. Classified under HTS 7306.69.70 due to being welded, noncircular, thin-walled alloy steel profiles. Meets chapter definition for hollow profiles not exceeding specified dimensions in wire note context.
Stainless Alloy Steel Square Hollow Section
Welded square hollow profiles of stainless alloy steel (e.g., 304 grade), wall under 4 mm, for architectural and furniture framing. Fits HTS 7306.69.70 as welded, noncircular cross-section, thin-walled alloy steel tube. Excludes circular or thick-walled variants.
Alloy Steel Welded Oval Tubing
Welded oval cross-section tubes from chrome-moly alloy steel, thin wall <4 mm, used in automotive exhaust prototypes. HTS 7306.69.70 covers welded noncircular hollow profiles of alloy steel with specified thinness. Differentiates from circular or seamless ovals.
Thin-Wall Alloy Steel D-Shaped Tubing
Welded D-profile hollow tubes of nickel-alloy steel, wall thickness 3 mm max, for aerospace non-structural supports. Precisely matches 7306.69.70: alloy, welded, noncircular, sub-4mm wall. Excludes riveted or open-seamed closures.
Alloy Steel Welded Triangular Hollow Profile
Specialty welded triangular cross-section tubes from high-strength alloy steel, <4 mm walls, for machinery guards. HTS 7306.69.70 applies to such noncircular welded alloy hollow profiles. Wire note cross-section limit not restricting here.
Chrome-Moly Alloy Steel Flat-Oval Tube
Welded flat-oval profile tubes of 4130 chrome-moly alloy steel, 2.5 mm wall, for bicycle frame prototypes. Classed in 7306.69.70 for thin-walled, noncircular welded alloy steel. Distinguishes from sports equipment finished goods.
Alloy Steel Welded Hexagonal Tubing
Welded hexagonal hollow sections from maraging alloy steel, wall 3.2 mm, for defense equipment mounts. HTS 7306.69.70: precisely welded noncircular thin alloy profiles. Not for pressurized apps per statistical notes.
Thin-Wall Alloy Steel Elliptical Pipe
Welded elliptical cross-section pipes of low-alloy steel, 1.8 mm wall, for decorative railings. Falls under 7306.69.70 as noncircular welded alloy hollows under 4 mm thick. Excludes open-seamed or circular.
Alloy Steel Welded L-Shaped Hollow Profile
Welded L-profile tubes of structural alloy steel, wall <4 mm, for conveyor framing. HTS 7306.69.70 captures welded noncircular thin alloy steel hollows. Differentiates from solid L-bars.
Nickel Alloy Steel Noncircular Welded Tube
Welded noncircular (octagonal) tubes from Inconel nickel alloy steel, 3.5 mm wall, for chemical processing supports. Matches 7306.69.70 criteria exactly: alloy, welded, thin noncircular. Not keg-related per notes.
Alloy Steel Welded Semicircular Hollow
Welded semicircular (D-profile) hollows of heat-resistant alloy steel, sub-4 mm wall, for furnace components. HTS 7306.69.70 for such thin welded noncircular alloys. Excludes full circular.
Structural Alloy Steel Welded T-Profile Tube
Welded T-shaped hollow profiles from high-tensile alloy steel, 2.8 mm walls, for bridge models. Fits 7306.69.70: noncircular welded thin alloy hollows. Not solid T-bars.
Alloy Steel Welded Custom Nonround Tube
Custom welded nonround (trapezoidal) tubes of quenched alloy steel, <4 mm wall, for robotic arms. HTS 7306.69.70 covers diverse noncircular welded thin alloys. Allows 'for example' open-seamed but specifies welded here.
Manganese Alloy Steel Welded Profile
Welded rectangular profiles with manganese alloy steel, 3 mm wall, for wear-resistant chute linings. 7306.69.70: alloy steel, noncircular, welded, thin wall. Manganese qualifies as alloying element.
Alloy Steel Thin Welded Half-Round Tube
Welded half-round noncircular tubes of silicon-manganese alloy steel, 2 mm wall, for architectural accents. Precisely HTS 7306.69.70: thin-walled welded alloy noncircular hollow profile. Aesthetic but structural form.
