Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of ordinary soda-lime glass
Glass without the specified low thermal expansion coefficient goes to the residual laboratory glassware subheading.
If sold as a carafe or bottle for serving
Similar shaped glass bottles for table/kitchen use are bottles/jars in heading 7010, not lab ware.
If Pre-charged lab vessels with chemicals become laboratory reagents under heading 3822.
