Import Tips & Compliance
• Verify the blanket is not a part of the instrument itself but an accessory, as parts of Chapter 90 instruments may be classified elsewhere
• If the blanket is made of vulcanised rubber, check if it falls under heading 40.16, which is excluded from Chapter 90
• Provide evidence of its use with specific Chapter 90 instruments to support classification under 9033
