Borosilicate Glass Beaker 500ml
A 500ml capacity laboratory beaker made from borosilicate glass, such as Pyrex, with a low linear coefficient of expansion not exceeding 5 x 10-6 per Kelvin (0-300°C), allowing it to withstand thermal shock. It is graduated for precise volume measurement and used in chemical experiments. Classified under HTS 7017.20.00.00 as laboratory glassware of specialized low-expansion glass.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of fused quartz or fused silica
Fused quartz glass has even lower expansion and falls under quartz-specific subheading in the same laboratory glassware heading.
If constructed primarily of ceramic materials
Laboratory porcelain or ceramic crucibles are classified in Chapter 69 for ceramic wares, not glass.
If in fibrous glass wool form for lab insulation
Fibrous glass forms like wool for thermal applications fall under heading 7019, per chapter notes on glass wool definition.

Import Tips & Compliance
• Verify borosilicate composition and thermal expansion certificate to confirm HTS 7017.20 classification over general glassware
• Include lab calibration certificates and ensure packaging prevents breakage during shipping
• Avoid misclassification as common glass; test coefficient if disputed by customs
