Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is oxygen gas, not a mixture of atmospheric gases
Separated individual gases are classified under their specific headings in Chapter 28.
If the product is a specific inorganic compound rather than a mixture
Other inorganic oxygen compounds are classified in heading 2811, not as liquid air.

Import Tips & Compliance
• Liquid air is classified as a dangerous good for transport; ensure your shipping documents comply with Transport Canada's regulations for cryogenic gases
• The CBSA may require a material safety data sheet and end-use declaration for industrial applications
• Verify that the product is not a mixture of separated gases, which could fall under other headings

2-inch Undoped Gallium Arsenide Test Wafer
A 2-inch undoped gallium arsenide test wafer is used for process control and calibration in semiconductor fabrication. Chapter Note 8 to Chapter 28 states that chemical elements doped for electronics are classified in this chapter only in unworked forms; however, gallium arsenide is a compound, not an element. Undoped wafers cut into discs or wafers fall under heading 3818, not this tariff item.
Aluminum Phosphide
> Aluminum phosphide is a chemically defined inorganic compound used primarily as a fumigant in agriculture to control pests in stored grains. As a phosphide of a metal other than iron, it is classified under heading 28.53, specifically this tariff item for other phosphides.
Aluminum Phosphide Tablets
Aluminum phosphide tablets are a chemically defined inorganic compound used for fumigation, generating phosphine gas upon exposure to moisture. As a phosphide other than ferrophosphorus, it falls under heading 2853. The tablets are presented in a form ready for use, but remain classified as the inorganic compound itself.
