Import Tips & Compliance
• Ensure the hose's burst pressure is certified at or above 27.6 MPa, as this is the key criterion for classification under 3917.31.00
• Provide technical datasheets to the CBSA officer upon request to verify the material composition and pressure rating
• Consider the end-use application; if the hose is part of a larger machine, it may be classified elsewhere in Section XVI
