What is the HS code for Rail Clips?
A rail clip is a metal component used to securely fasten a train rail to a baseplate or sleeper below it, preventing movement and ensuring the integrity of the track. They work by applying pressure on the rail, which resists longitudinal and lateral shifts caused by temperature changes, vibration, and impact from trains. These clips are a critical part of a rail fastening system and are often made of forged spring steel for durability.

- Function: Rail clips hold the rail in place, maintain track gauge, and absorb impact and vibration. They transfer lateral forces from the rail to the supporting structure.
- Mechanism: They use bending and distortion to create a clamping force on the rail, which prevents it from moving.
- Material: Most are made from forged spring steel because the process creates a uniform microstructure that improves strength and durability.
- Durability: They are designed to withstand bending, torsion, fatigue, corrosion, and high impact loads from trains.
- Alternatives: While spikes and chairs are other methods of fastening rails, clips are considered a more reliable and modern solution.
The HS code for Rail Clips
The HS code for rail clips is 7302.90, which falls under the broader category of "Railway or tramway track construction material of iron or steel". Specific subcategories, such as 73029010 for elastic rail clips, may also be used for more detailed classification, with other classifications like 73029090 used for different types of rail clips.
- HS Code 7302.90: This is the primary HS code for "sleepers (cross-ties), check-rails, rack rails, chairs, chair wedges, rail clips, bedplates and ties and other specialised material for the jointing or fixing of railway or tramway track, of iron or steel".
- HS Code 73029010: Used for specific types, such as elastic rail clips.
- HS Code 73029090: Another sub-category used for other types of rail clips.
