Import Tips
• Due to its volatility, ensure proper containment and declare the hazard class on shipping documents
• The CBSA may require a certificate of analysis to confirm the WCl4O formula
• If used for optical coatings, verify if it is classifiable as an optical element, which would fall under Chapter 90
