Import Tips & Compliance
• Verify the bearing type (ball or roller) and housing material via manufacturer specs to confirm classification under 8483.20.80
• Include detailed engineering drawings and test reports in documentation to avoid misclassification as parts of machines in Chapter 84
• Check for country-of-origin marking requirements, as these are often used in food processing where stainless steel housings are common
