Import Tips & Compliance
• Confirm the inhibitor concentration (50 ppm) and its purpose as a stabilizer to CBSA, as permitted by Chapter note 1(f)
• Provide the inhibitor's chemical name (hydroquinone monomethyl ether) on the safety data sheet
• Ensure the product is labeled as 'stabilized propylene oxide' to avoid confusion with unstabilized grades
