Glass in balls (other than microspheres of heading no. 7018), rods or tubes, unworked
In plain English
This category covers unworked glass shaped into balls, rods, or tubes, excluding microspheres. The items are separated into groups based on their specific form and material properties. One group includes glass balls and rods, while others distinguish tubes by whether they are made of fused quartz, fused silica, or glass with a very low expansion rate. Tubes made of other types of glass that do not meet the low expansion criteria fall into the final group.
