Import Tips & Compliance
• Ensure the hose's burst pressure is certified at 27.6 MPa, as CBSA may request this
• If the hose is used in chemical processing plants, it may be part of a larger system, but as a standalone hose, it stays in Chapter 39
• Check if the hose has metal end fittings, which may require separate classification
