Iridium, Osmium, and Ruthenium, Semimanufactured

Because platinum-group metal prices can fluctuate dramatically, CBP may scrutinize transaction value closely. Importers should retain contemporaneous purchase contracts, refinery certificates of analysis, and any spot-price reference benchmarks (such as London Platinum and Palladium Market fixings) used to establish the invoice price. A clear audit trail linking the declared value to a recognized market price on or near the date of export strengthens the valuation position.

Finished iridium crucibles are articles of a specific shape and function and would generally be classified as laboratory or industrial equipment rather than as semimanufactured precious metal. Semimanufactured iridium under 711049 covers intermediate forms — wire, rod, sheet, strip, tube — that still require further fabrication to become a finished article. The key test is whether the item retains the character of a semi-finished metal form or has already become a complete, identifiable end product.
