Import Tips
• Ensure the sprayer is not classified as a machine of heading 84.86 (e.g
• for manufacturing semiconductors) — if it is solely for semiconductor fabrication, it may be excluded from 84.24
• Provide a detailed technical datasheet to the CBSA showing the projecting/dispersing function
• Verify if any provincial regulations apply to hydrofluoric acid handling equipment
