Pure Iridium Sponge from Mexico
Porous iridium sponge produced via chemical precipitation and reduction, serving as an intermediate form before consolidation into ingots. Falls under HTS 7110.41.00.10 as unwrought iridium, distinct from powder due to particle size exceeding subheading note's 0.5mm sieve threshold. Used in electronics and aerospace manufacturing.

Import Tips
• Conduct sieve analysis to confirm not 'powder form' per subheading note; provide chemical reduction process documentation
• Common pitfall: undervaluation based on sponge density—declare gross weight accurately
