Subheadings
Products classified under Tariff item 2910.10.00
99.5% Ethylene Oxide Technical Grade
Technical-grade ethylene oxide at 99.5% purity, used as a chemical intermediate in the production of surfactants and other industrial chemicals. It is a separate chemically defined organic compound with a three-membered epoxide ring, falling squarely within tariff item 2910.10.00.
Ethylene Oxide 99.9% Purity USP Grade
High-purity ethylene oxide (99.9%) meeting USP standards for pharmaceutical applications. It is a separate chemically defined epoxide with a three-membered ring, classified under tariff item 2910.10.00 based on its chemical structure.
Ethylene Oxide for Ethylene Glycol Production
Technical-grade ethylene oxide used as a feedstock for ethylene glycol production. As a separate chemically defined epoxide with a three-membered ring, it is classified under tariff item 2910.10.00 regardless of its intended industrial application.
Ethylene Oxide in DOT-39 Cylinders
Compressed ethylene oxide gas packaged in non-refillable DOT-39 cylinders for industrial transport. The packaging is a standard method for shipping this epoxide and does not alter its classification as oxirane under tariff item 2910.10.00.
Ethylene Oxide in ISO Tank Containers
Ethylene oxide transported in ISO tank containers for international chemical trade. The container type does not affect the product's classification as oxirane under tariff item 2910.10.00, as it remains a pure epoxide.
Ethylene Oxide (Pure)
Pure ethylene oxide (C2H4O), a colourless, flammable gas with a three-membered epoxide ring. It is a fundamental organic compound used in industrial chemical synthesis and is classified under tariff item 2910.10.00 as oxirane.
Ethylene Oxide Railcar Bulk Import
Bulk ethylene oxide shipped in rail tank cars for petrochemical manufacturing. The product is a pure epoxide with a three-membered ring, classified under tariff item 2910.10.00, with the packaging serving only for transport.
Ethylene Oxide with Color Indicator
Ethylene oxide with a colouring agent added for identification purposes, as permitted under Chapter 29 note 1(g). The colouring does not render the product suitable for a specific use, so it remains classified as oxirane under tariff item 2910.10.00.
Ethylene Oxide with Emetic Additive
Ethylene oxide with an added emetic for safety identification, as allowed under Chapter 29 note 1(g). The emetic is added to facilitate identification and does not make the product suitable for a specific use, so it remains classified under tariff item 2910.10.00.
High-Pressure Ethylene Oxide Solution 10% in Water
An aqueous solution of ethylene oxide at 10% concentration, diluted for safe handling and transport. Under Chapter 29 note 1(d), solutions of chemically defined compounds in water are classified in the same heading, so this falls under tariff item 2910.10.00.
Industrial Ethylene Oxide for Sterilization
Ethylene oxide designated for gas sterilization in medical device manufacturing. Despite its specific end-use, it remains a separate chemically defined compound with an epoxide ring, classified under tariff item 2910.10.00.
Pharma-Grade Ethylene Oxide with Anticaking Agent
Pharmaceutical-grade ethylene oxide with an added anti-caking agent for preservation, as permitted under Chapter 29 note 1(f). The stabilizer is necessary for preservation and does not alter the product's classification as oxirane under tariff item 2910.10.00.
Reagent-Grade Ethylene Oxide 99.99%
Ultra-high purity reagent-grade ethylene oxide (99.99%) for laboratory synthesis. As a separate chemically defined epoxide with a three-membered ring, it is classified under tariff item 2910.10.00.
Stabilized Ethylene Oxide with Inhibitor
Ethylene oxide with a stabilizer added for safe transport, as allowed under Chapter 29 note 1(f). The stabilizer is solely for preservation and does not change the product's classification as oxirane under tariff item 2910.10.00.
Sterile Ethylene Oxide for Medical Gas
Sterile-grade ethylene oxide gas for hospital sterilizers, a pure epoxide with a three-membered ring. Its sterile grade does not affect classification, and it falls under tariff item 2910.10.00 as oxirane.
