Nitrosyl Chloride
Nitrosyl chloride (NOCl) is a yellow-red gas or liquid used as a nitrosating agent in pharmaceutical synthesis. It is classified under tariff item 2811.19.00 as an 'other inorganic oxygen compound of non-metals' because it is a separate chemically defined compound of nitrogen, oxygen and chlorine, not specifically named elsewhere in Chapter 28.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is a halide oxide of a non-metal other than carbon
Halide oxides of non-metals may be classified in heading 28.12, depending on their specific composition.
If the product is ammonium chloride rather than nitrosyl chloride
Ammonium chloride is specifically classified in heading 28.27.
If the product is a mixture containing nitrosyl chloride and other compounds
Mixtures not meeting the definition of a separate chemically defined compound are classified in Chapter 38.

Import Tips & Compliance
• Nitrosyl chloride is a reactive and corrosive gas; you must comply with Transport Canada dangerous goods regulations and provide the proper UN number (UN 1069)
• The CBSA may request a certificate of analysis to confirm the chemical identity
• Verify that the product is not a halide oxide of carbon, which would be classified in heading 28.12
