HS Code for Glass tubes

HS code 7002.39 covers glass tubes that are unworked and do not meet the specific thermal expansion or material composition requirements of other subheadings within 7002. This code is part of the 'Glass and Glassware' chapter and specifically addresses glass in its primary, semi-manufactured form. To qualify for this code, the glass must be in the form of a tube—a hollow cylinder of uniform thickness. The 'unworked' status is critical; it means the glass has not been subjected to further processing such as bending, sealing, or being converted into a specific finished product like a test tube or a neon sign component. Subheading 7002.39 is a residual category for tubes that are not made of fused quartz (7002.31) and do not have a low linear coefficient of expansion (7002.32). This classification is vital for manufacturers who import raw glass tubing for later fabrication into medical, industrial, or lighting products. The glass must not have been worked beyond simple cutting to length or surface treatment that does not change its fundamental shape as a tube.

Products Included

• Soda-lime glass tubing in bulk lengths
• Lead glass tubes for neon lighting (unworked)
• Standard glass tubes for industrial piping
• Unworked glass cylinders for gauge glasses
• Aluminosilicate glass tubes (not low expansion)

Common Misclassification

The most common misclassification occurs with HS code 7017, which covers laboratory, hygienic, or pharmaceutical glassware. If the tube has been worked (e.g., one end sealed to form a test tube or graduated markings added), it moves from 7002 to 7017. Additionally, tubes with a linear coefficient of expansion not exceeding 5 x 10^-6 per Kelvin must be classified under 7002.32, and fused silica tubes must be under 7002.31. Confusing these based on material composition is a frequent compliance error.

FAQ

What is the HS code for Glass tubes?

The HS code for unworked glass tubes (other than fused silica or low-expansion glass) is 7002.39.

Does this code include glass rods?

No, glass rods are classified under HS code 7002.20, as they are solid rather than hollow.
