Products classified under HTS 7320.20.50.60
Stainless Steel Compression Helical Spring
A helical spring made of stainless steel designed to compress under load and return to its original shape, commonly used in automotive suspensions and machinery. It falls under HTS 7320.20.5060 as a helical spring of iron or steel, classified as 'other' within the 'other' subcategory for non-coil or specific use springs. This classification applies to finished helical springs not specified elsewhere in the subheading.
Carbon Steel Extension Helical Spring
A carbon steel helical spring that extends when pulled and contracts back, used in garage doors and trampolines. Classified under HTS 7320.20.5060 as 'other' helical springs of iron or steel, excluding those for specific vehicle or coil applications. Meets Chapter 73 definition for non-wire springs exceeding simple wire form.
Music Wire Torsion Helical Spring
High-carbon steel music wire helical spring that resists twisting forces, used in clothespins and mechanical timers. Falls under HTS 7320.20.5060 for other helical springs of iron or steel, as a finished torsion type not covered by prior subheadings. Precision-formed beyond raw wire per chapter notes.
Alloy Steel Die Spring for Presses
Heavy-duty rectangular-section helical spring from alloy steel for industrial stamping presses. HTS 7320.20.5060 covers this as other helical springs of iron or steel, distinct from standard round-wire types. Designed for high-load compression in manufacturing equipment.
Chrome Silicon Valve Spring
Helical compression spring made of chrome silicon steel for engine valves in motorcycles. Classified in HTS 7320.20.5060 as other helical springs, not specific to vehicle suspension. High-fatigue resistance suits high-RPM applications.
Steel Clock Mainspring Helical
Precision helical mainspring of hardened steel for mechanical clocks and watches. Under HTS 7320.20.5060 for other iron/steel helical springs, excluding specialized timepiece parts. Provides power storage via coiling mechanism.
Galvanized Steel Retractable Cord Spring
Galvanized helical spring for retractable extension cords and hoses. HTS 7320.20.5060 as other helical springs of iron or steel, for consumer and light industrial retraction. Corrosion-resistant coating for outdoor use.
High-Tensile Steel Battery Spring Contact
Helical spring contact of high-tensile steel for battery compartments in electronics. Falls under HTS 7320.20.5060 for other iron/steel helical springs used in small devices. Ensures reliable electrical connection under vibration.
Precision Ground Helical Spring
Ground finish helical spring from tool steel for medical devices and instruments. HTS 7320.20.5060 covers other finished helical springs of iron or steel with precision tolerances. Used in surgical tools for consistent performance.
Double Torsion Helical Spring
Steel helical spring with legs on both ends for counterbalancing in hinges. Classified HTS 7320.20.5060 as other helical torsion springs of iron or steel. Common in cabinet hardware and small mechanisms.
