Phosphorus Oxychloride
Phosphorus oxychloride (POCl3), also known as phosphoryl chloride, is a colorless liquid used in organic synthesis and as a chlorinating agent. 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 phosphorus, oxygen and chlorine.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is phosphoric acid rather than phosphorus oxychloride
Phosphoric acids are specifically classified in heading 28.09.
If the product is a halide of phosphorus without oxygen
Halides of non-metals are classified in heading 28.12.
If the product is a mixture containing phosphorus oxychloride and other compounds
Mixtures not meeting the definition of a separate chemically defined compound are classified in Chapter 38.

Import Tips & Compliance
• Phosphorus oxychloride reacts violently with water, so it must be shipped in sealed, moisture-proof containers; include this in the shipping documentation
• The CBSA may require a certificate of analysis to confirm the product is POCl3 and not a mixture
• Verify whether the product is subject to import controls as a chemical precursor under Canadian regulations
