Subheadings
Products classified under Tariff item 2811.21
Dry Ice Blocks for Shipping
Dry ice is the solid phase of carbon dioxide, a separate chemically defined compound of non-metal oxygen. It is classified under tariff item 2811.21.00 as carbon dioxide, regardless of physical state, and is not excluded by Chapter 28 notes.
2811.21.00Food-Grade CO2 for Beverage Carbonation
Food-grade carbon dioxide is a pure, chemically defined inorganic compound of carbon and oxygen, meeting Chapter 28 note 1 criteria. It falls under tariff item 2811.21.00 as carbon dioxide, even when used in beverages.
2811.21.00Industrial Carbon Dioxide Gas Cylinder
Industrial carbon dioxide gas in cylinders is a separate chemically defined compound, classifiable under tariff item 2811.21.00. The steel cylinder is packaging, not a separate good, and does not affect classification.
2811.21.00Laboratory Carbon Dioxide 99.999% Pure
Ultra-high purity laboratory carbon dioxide is a separate chemically defined compound, meeting Chapter 28 note 1(a). It is classifiable under tariff item 2811.21.00, with no exclusions for laboratory use.
2811.21.00Liquid Carbon Dioxide Bulk Tanker
Liquid carbon dioxide in bulk tankers is carbon dioxide in a liquid state, a separate chemically defined compound. It falls under tariff item 2811.21.00, as the heading covers all physical states of CO2.
2811.21.00Medical-Grade Carbon Dioxide USP
Medical-grade carbon dioxide USP is a pure, chemically defined compound of carbon and oxygen, classifiable under tariff item 2811.21.00. Chapter 28 notes do not exclude pharmaceutical-grade inorganic compounds unless put up as medicaments (Chapter 30).
2811.21.00pH Correction Carbon Dioxide
Carbon dioxide for pH correction is a separate chemically defined compound, classifiable under tariff item 2811.21.00. Its use to form carbonic acid in solution does not change its identity as CO2.
2811.21.00Welding Shielding Gas CO2
Welding shielding gas carbon dioxide is a pure, chemically defined compound, classifiable under tariff item 2811.21.00. The heading covers CO2 regardless of industrial application, and no Chapter 28 exclusion applies.
