Unworked Soda-Lime Glass Balls
Spherical soda-lime glass balls, unworked except for annealing, used as precursors for manufacturing precision bearings and valves. They fall under HTS 7002.10.20.00 as 'other' glass balls not classified as microspheres of heading 7018, with no further processing beyond basic forming.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If average diameter not exceeding 6mm
Microspheres of heading 7018 apply to smaller glass balls used in fillers or abrasives, shifting from unworked balls in 7002.
If precision ground and used as bearing balls
Finished ceramic or glass balls for bearings are classified by end-use in Chapter 84, not as unworked glass.
If supplied as unworked glass rods instead of balls
Same unworked glass in rod form falls under 7003, differentiated by shape rather than composition.

Import Tips & Compliance
• Verify balls are unworked (no cutting, grinding, or polishing post-annealing) to avoid reclassification under heading 7007 as worked glass
• Provide mill test certificates confirming composition and dimensions to demonstrate compliance with 'balls other than microspheres' criteria
