Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If drawn and formed into laboratory spheres
Drawn glass labware in 7017 applies post-working, unlike unworked balls.
If in rod form under 5 mm diameter
Unworked rods under 5 mm classify separately from balls in 7002.20.
If sintered into ceramic articles
Glass frit sintered into crucibles shifts to porcelain/ceramic classifications.

Import Tips & Compliance
• Obtain FDA registration if for medical end-use, though classification remains unworked glass
• Use precise measurement certificates; tolerances over 6 mm trigger higher subheadings
• Document lack of lead content if marketed as crystal, avoiding 7013 confusion
