Rhenium Catalyst Waste from China
Spent rhenium-impregnated catalyst residues from petroleum refining processes, containing recoverable rhenium metal. Classified under HTS 8112.41.10.00 as waste and scrap of rhenium due to its primary rhenium content exceeding other metals and being unsuitable for direct use. This scrap is typically recycled to extract rhenium for reuse in high-performance alloys.

Import Tips
• Verify rhenium content via assay certificate to confirm classification under 8112; impurities below 99% still qualify if rhenium dominates
• Obtain EPA waste import permits if classified as hazardous due to petrochemical residues; provide recycling end-use documentation
• Avoid misclassification as Chapter 27 petroleum waste by emphasizing metallic rhenium recovery value
