Palladium Sponge from China
Porous palladium sponge produced by precipitation and reduction, a semimanufactured intermediate form before pressing into ingots. Classified under HTS 7110.29.00.00 as 'other' palladium, not qualifying as powder per subheading note (less than 90% through 0.5mm sieve). Commonly used in chemical catalysis and hydrogen purification.

Import Tips
• Provide particle size analysis to distinguish from powder form; sieve test required for compliance
• Declare intended end-use (e.g
• catalysis) but classify based on form, not use; EPA TSCA may apply for chemical imports
• Watch for alloy contamination; if ruthenium exceeds predominance, reclassify per alloy rules in chapter note 4
