HS Code for Screw making machine

The classification of a screw making machine under HS code 8463.20 is based on the specific metalworking process it employs. Heading 8463 encompasses machine-tools for working metal, sintered metal carbides, or cermets, without removing material. Screw production typically involves thread rolling, a cold-forming process where the metal is displaced by hardened steel dies to create threads. This is distinct from thread cutting or grinding, which removes material. According to the Harmonized System Explanatory Notes, heading 8463 includes machines that change the shape of metal through pressure or deformation. Subheading 8463.20 specifically identifies "thread rolling machines." If a machine is designed to produce screws by rolling threads onto a blank, it must be classified here. This applies to both manual and fully automated CNC thread rollers. The classification is determined by the primary function of the machine tool, which is the non-subtractive formation of threads rather than the removal of metal shavings.

Products Included

• Thread rolling machines
• Cold heading machines for screw blanks
• Automatic screw-making lathes (non-cutting)
• Flat die thread rollers
• Circular die thread rollers
• Planetary thread rolling machines

Common Misclassification

These machines are often misclassified under HS code 8459.70, which covers threading or tapping machines that remove material. The key distinction is whether the machine cuts the thread (8459) or rolls it (8463). Additionally, some importers mistakenly use 8462.90 for general forging or stamping machines, but 8463.20 is more specific for thread-forming equipment and thus takes precedence under the rules of specific description.

FAQ

What is the HS code for screw making machine?

The primary HS code for a screw making machine that utilizes thread rolling technology is 8463.20.

Does this code cover machines that cut threads?

No, machines that produce screws by cutting or removing metal are classified under heading 8459, specifically 8459.70 for threading machines.
