Product classification
HS code for Glass tubes: 7002.39
Glass, unworked, in tubes, other than of glass having a linear coefficient of expansion not exceeding 5 x 10 (to the minus 6, (or 0.000005) ) per Kelvin within a temperature range of 0-300 degrees C, not fused quartz or other fused silica.
Classification of glass tubes under HS 7002.39
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.
- Covers
- 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)
- Also under 7002.39
- General lighting manufacturers (for raw tubes)
- specific art glass suppliers
- basic laboratory glassware producers
- packaging glass manufacturers
Codes often confused with 7002.39
Common mistake. 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.
Top exporters and importers of HS 700239 (the code used for glass tubes), 2025
In 2025, the largest exporter of HS 700239 (the code used for glass tubes) in UN Comtrade data was the Philippines, with 22% of world exports; the largest importer in UN Comtrade data was France, with 13% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about glass tubes
What is the HS code for Glass tubes?
The HS code for Glass tubes is 700239 (Glass; unworked, in tubes, other than of glass having a linear coefficient of expansion not exceeding 5 x 10 (to the minus 6, (or 0.000005) ) per Kelvin within a temperature range of 0-300 degrees C, not fused quartz or other fused silica). The HS code for unworked glass tubes (other than fused silica or low-expansion glass) is 7002.39.
How do I classify Glass tubes for customs?
Glass tubes is classified under HS code 700239 — Glass; unworked, in tubes, other than of glass having a linear coefficient of expansion not exceeding 5 x 10 (to the minus 6, (or 0.000005) ) per Kelvin within a temperature range of 0-300 degrees C, not fused quartz or other fused silica. This is a 6-digit subheading level code.
Does this code include glass rods?
No, glass rods are classified under HS code 7002.20, as they are solid rather than hollow.
Which countries are the top exporters of glass tubes (HS 700239)?
In 2025, the top exporters of HS 700239 (the code used for glass tubes) in UN Comtrade data were the Philippines ($53M, 22% of world exports), Malaysia ($41M) and Italy ($37M). World exports came to about $247M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
