Ethylene for LDPE Autoclave Process
Specially purified ethylene for LDPE autoclave processes is a separate chemically defined organic compound. The low metal and sulfur content are impurities, not additives, so it remains classified under tariff item 2901.21.00.

Import Tips & Compliance
• Keep records of the ethylene's purity and impurity profile for CBSA verification
• Ensure the product is shipped in approved containers for hazardous gases
• Check if the end-use in polymer production requires any special permits
Related Products under Tariff item 2901.21.00
Cryogenic Liquid Ethylene
Cryogenic liquid ethylene is ethylene (C2H4) in a liquefied state at very low temperatures for bulk transport. It is a separate chemically defined organic compound, and its physical state does not affect its classification under tariff item 2901.21.00.
Ethylene Calibration Gas 1.0%
This product is a mixture of 1.0% ethylene in nitrogen, used as a calibration gas. It is not a separate chemically defined compound, and the nitrogen solvent is not for safety or transport but for a specific analytical use, so it does not meet Chapter 29 criteria. It is excluded from this heading.
Ethylene for Ethylbenzene Production
Ultra-high purity ethylene (99.99%) for ethylbenzene production is a separate chemically defined organic compound. Its intended use in styrene synthesis does not alter its classification as ethylene under tariff item 2901.21.00.
Ethylene for Fruit Ripening (Technical Grade)
Technical grade ethylene (98%+) for fruit ripening is a separate chemically defined organic compound, even with impurities. The impurities do not make it a mixture of isomers or a product of other headings, so it falls under tariff item 2901.21.00.
Medical Grade Ethylene for Anesthesia
Medical grade ethylene for anesthesia is a separate chemically defined organic compound. Its pharmaceutical grade and use do not change its classification under tariff item 2901.21.00, as Chapter 29 covers such compounds regardless of purity.
Polymer Grade Ethylene
Polymer grade ethylene (99.9%+) is a separate chemically defined organic compound used as a monomer. It is not a polymer itself, so it is correctly classified under tariff item 2901.21.00 as an unsaturated acyclic hydrocarbon.
