HS Code for Dry ice

Dry ice is the solid form of carbon dioxide and is classified under HS code 2811.21. Chapter 28 of the Harmonized System covers inorganic chemicals, and heading 2811 is designated for "Other inorganic acids and other inorganic oxygen compounds of non-metals." Carbon dioxide (CO2) is specifically identified in subheading 2811.21. The classification remains the same regardless of whether the carbon dioxide is in a gaseous, liquid, or solid state. Dry ice is produced by compressing and cooling gaseous CO2 until it liquefies, then allowing it to expand rapidly to form a "snow" which is then compressed into blocks or pellets. Because it is a chemically defined compound (CO2), it must be classified in Chapter 28 according to Note 1 to that chapter, which states that the headings apply to separate chemical elements and separate chemically defined compounds. Its use as a refrigerant or for stage effects does not alter its classification as a basic inorganic chemical.

Products Included

• Solid carbon dioxide blocks
• Dry ice pellets for blast cleaning
• Dry ice slices for food transport refrigeration
• Compressed CO2 snow

Common Misclassification

Dry ice is often misclassified under HS code 2201.90, which covers "ice and snow." However, heading 2201 is strictly for water-based ice (H2O). Another common error is using HS code 3824.99, which is a catch-all for chemical products not elsewhere specified. Since carbon dioxide is specifically named in 2811.21, the rules of specificity (GRI 3a) dictate that the specific chemical code must be used. Additionally, it should not be confused with liquid nitrogen (2804.30), which is also used for cooling but has a different chemical identity.

FAQ

What is the HS code for Dry ice?

The HS code for dry ice (solid carbon dioxide) is 2811.21.

Does the packaging for transport change the HS code?

No, the HS code 2811.21 applies to the substance itself. While the insulated containers used to ship dry ice may have their own classification (e.g., Chapter 39 or 73), the dry ice remains 2811.21.
