Hiwin HGH20CA Linear Carriage Block
Hiwin HGH20CA is a heavy-load linear ball bearing block with equal load in all directions, used in semiconductor wafer polishing equipment for precise table motion. Falls under HTS 8482.10.5012 as a complete linear bearing unit.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If balls imported separately for bearing assembly
Individual bearing balls are classified apart from complete bearing assemblies.
If basic steel rail profiles without precision grinding
Unfinished rail stock may classify as other steel articles rather than bearing parts.
If complete wafer inspection stage assembly
Finished semiconductor testing machines incorporating linear bearings classify in 8479.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Classify based on complete unit (block + balls + retainer); loose balls classify differently under 8482.91
• Provide assembly drawings showing 4-row circular-arc contact ball path design
• For anti-creep versions, include performance test data distinguishing from standard blocks
