HS-6 · Subheading
281121
Carbon dioxide
Heading 2811 — Inorganic acids and other inorganic oxygen compounds of non-metals; n.e.c. in heading no. 2806 to 2810
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 281121 when importing or exporting carbon dioxide, a colorless gas commonly used in beverages, refrigeration, and as a chemical feedstock. For example, if you're shipping carbon dioxide cylinders for carbonating drinks, this is the correct code.
This code specifically covers carbon dioxide, distinguishing it from other inorganic compounds like carbon monoxide or carbon disulfide, which fall under different HS codes. If you're dealing with a product that contains carbon dioxide but is mixed with other substances, you may need to look at other classifications.
Carbon dioxide is often found in various forms, such as liquid or gas, and is utilized in industries ranging from food and beverage to pharmaceuticals. Be sure to check if your shipment meets the criteria for this HS-6, especially if it’s in a compressed gas cylinder or as a refrigerant.
When classifying your goods, consider the specific use and form of carbon dioxide. For instance, if you are exporting dry ice (solid carbon dioxide), you would need to look at a different classification under the same chapter.
