Import Tips

Label units with bore diameter, speed rating, and load capacity; Customs often requests this for verifying 'housed bearing' status

Avoid common pitfall of classifying as 'parts of machines' (8479); prove it's a complete housed unit with assembly photos

For food-grade applications, ensure FDA-compliant grease and provide material safety data sheets (MSDS)
