Import Tips

• Verify material certification confirming sintered samarium-cobalt composition to avoid reclassification to neodymium magnets (8505.11.0070)

• Provide magnetization certificates if imported pre-magnetized, as 'articles intended to become permanent magnets' must be clearly documented

• Ensure RoHS compliance documentation, as rare-earth magnets may contain trace hazardous substances subject to EU REACH equivalents
