Platinum Sponge Nuggets
Porous nuggets formed from platinum sponge, a intermediate refining product consolidated into larger unwrought lumps for remelting. HTS 7110.11.00.10 covers these as grains/nuggets of platinum metal, provided not further processed into powder or sheet. Used in chemical catalysis and electronics manufacturing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If crumbled to powder form <0.5mm
Subheading note mandates powder classification based on sieve aperture; compaction into nuggets keeps unwrought grain status.
If supported on catalyst carrier
Platinum impregnated on alumina/ceramic becomes spent catalyst support, shifting to Chapter 38.
If pressed into semimanufactured pellets
Mechanical forming beyond nugget shape classifies as 'other' forms like anodes or gauze.

Import Tips & Compliance
• Specify 'sponge-derived nuggets' on invoice; loose sponge powder risks 7110.11.0050 if sieve test met
• Monitor LBMA good delivery standards for pricing; declare London Fix value basis

Platinum Investment Nuggets
Small, irregular nuggets of pure platinum metal, typically weighing between 1/10 oz and 1 oz, used primarily by investors for bullion purchases. These qualify under HTS 7110.11.00.10 as 'grain and nuggets of the metal platinum' because they are unwrought forms, not processed into bars, sheets, or other semimanufactured shapes. Purity is usually 99.95% or higher, certified by refiners like Johnson Matthey.
Platinum Grain for Jewelry Casting
Granular platinum grains (1-3mm irregular shapes) melted down by jewelers for custom casting of rings and settings. Classified in HTS 7110.11.00.10 as unwrought grains of platinum metal, distinct from powder due to larger particle size not meeting the 0.5mm sieve threshold. Sourced from refineries, hallmarked with serial numbers for traceability.
1 Gram Platinum Nugget Specimen
A single 1-gram natural-shaped platinum nugget sold to collectors and investors as a specimen of native platinum. Falls under HTS 7110.11.00.10 for unwrought grain/nuggets, unwrought meaning not manufactured into standard shapes like bars. Often encased in plastic for display, with purity stamped at 99.95%.
Platinum Placer Nuggets
Naturally occurring platinum nuggets extracted from alluvial deposits in the Ural Mountains or Alaska, minimally processed by washing. These raw grains/nuggets fall under HTS 7110.11.00.10 as unwrought platinum metal for refiners. Contain minor PGM impurities but classified by predominant platinum.
Recycled Platinum Melt Nuggets
Nuggets produced by remelting jewelry scrap and dental alloy into unwrought form for redistribution to fabricators. HTS 7110.11.00.10 applies to these pure platinum grains, treated identically to primary metal per tariff rules. Certified recycled content appeals to ESG-focused buyers.
10 Ounce Platinum Nugget
Large 10 troy ounce irregular platinum nugget marketed to high-net-worth investors and central banks as store of value. Pure unwrought platinum qualifies for HTS 7110.11.00.10 as nuggets, assayed and serialized by mints like PAMP Suisse. Larger size distinguishes from standard cast bars.
