Subheadings
Products classified under HTS 7320.90.50
Steel Torsion Spring for Clamps
A torsion spring made of steel wire that provides rotational force, commonly used in binder clips and hose clamps. It is included in HTS 7320.90.50 for other iron or steel springs not elsewhere specified. The wire cross-section adheres to the chapter's 16 mm limit.
Volute Spring for Shock Absorbers
Conical spiral steel spring that compresses progressively, applied in shock absorbers and recoil systems. Included in HTS 7320.90.50 for other steel springs beyond basic helical types.
Clock Spring for Steering Columns
Flat spiral steel spring wound in a clock-like coil for storing rotational energy in turn signal mechanisms. Classified HTS 7320.90.50 as other steel springs for automotive and appliance uses.
Negator Spring Strip
Pre-coiled flat steel strip spring for constant tension retrieval in seat belts and lanyards. HTS 7320.90.50 for other steel springs including strip types meeting wire specs.
Hairpin Clip Spring
U-shaped steel wire spring for quick-release clips in electronics and automotive trim. Falls in HTS 7320.90.50 as other simple wire springs.
Cantilever Spring Arm
Single-arm steel spring deflecting under load for parking brakes and levers. HTS 7320.90.50 for non-leaf cantilever springs.
Snap Spring Ring
Circlip-type steel spring ring snapping into grooves for shaft retention. Classified 7320.90.50 as retaining spring.
Bowed V-Spring Washer
V-profile steel washer spring providing light axial force in assemblies. HTS 7320.90.50 other springs.
Stainless Steel Compression Spring
A helical spring made from stainless steel wire, designed to resist compression forces and return to its original shape. It falls under HTS 7320.90.50 as an 'other' spring of iron or steel, not specified elsewhere in the subheading. Commonly used in automotive suspensions and machinery.
Music Wire Extension Spring
An extension spring crafted from high-carbon music wire, featuring loops at both ends for attachment and providing force when stretched. Classified in HTS 7320.90.50 as other springs of steel, distinct from compression or torsion types. Ideal for trampolines and garage doors.
Constant Force Spring Reel
A pre-stressed steel strip wound into a reel that exerts uniform force over extension, used in retractable cords and tape measures. Falls under HTS 7320.90.50 as other springs of steel, where the strip qualifies under the wire definition by cross-section.
Die Spring for Presses
Heavy-duty rectangular or round steel spring used in die sets for stamping presses to cushion impact. Classified under HTS 7320.90.50 as other industrial springs of iron or steel. Meets wire dimension limits for high-load applications.
Wave Spring Washer
A flat steel spring washer with undulating waves providing axial load in tight spaces, used in bearings and valves. HTS 7320.90.50 covers such other spring forms of steel wire or strip.
Belleville Disc Spring
Conical disc-shaped steel spring that stacks for high load capacity, used in bolted joints and safety valves. HTS 7320.90.50 applies to these other iron or steel spring configurations.
Garolite Compression Spring
Cylindrical steel pin with axial slot that compresses for press-fit insertion, functioning as a spring pin in assemblies. Though pin-like, classified under HTS 7320.90.50 for its spring action per tariff structure.
