Import Tips
• Provide NMR and structural analysis confirming aromatic organo-inorganic nature and metal-carbon bonding
• Include DEA documentation if used in pharmaceutical intermediates; ensure precious metal content declaration
• Prevent reclassification to Chapter 28 by emphasizing organic ligand-metal bonding over inorganic salt nature
