A PGM product supplier turns refined platinum (Pt, atomic number 78, CAS 7440-06-4) and its group metals into a finished form, such as wire, a crucible or a chemical catalyst, rather than mining or refining the metal itself. This page groups those suppliers into categories, sets out what separates a product supplier from a refiner or a bullion dealer, and lists what to check before placing an order.
What Is a PGM Product Supplier?#
A PGM product supplier is a fabricator or distributor, not a refiner and not a bullion dealer: it buys refined platinum group metal and sells it back as a manufactured product, such as wire or foil, or as a lab-scale chemical compound. The refiner upstream of it produces sponge, bar or ingot to a purity standard; the product supplier then draws, rolls, sinters or synthesizes that raw metal into the form a laboratory, a manufacturer or a catalyst maker orders. Several of the platinum group metal refiners this site profiles, including Johnson Matthey, Umicore, Heraeus and Tanaka, also run fabrication divisions, so the same name can appear as both refiner and product supplier. A bullion dealer, by contrast, sells investment bars and coins to individual buyers and holds no fabrication role at all.
PGM Supplier Categories#
DailyPlatinum groups PGM product suppliers into three categories: wire and thermocouple wire, laboratory labware, and chemical catalysts. Wire suppliers draw platinum and platinum-rhodium alloy into fine gauges for thermocouples and resistance elements, the same platinum-rhodium pairing used in the Type R and Type S thermocouples this site covers elsewhere. Labware suppliers fabricate crucibles, dishes and gauze from pure platinum or platinum-gold alloy, chosen for its resistance to melting and to molten-flux attack. Catalyst suppliers manufacture and distribute industrial and laboratory PGM catalysts, from platinum and palladium on carbon to homogeneous complexes; sputtering targets, a thin-film coating form, fall under this same category rather than a dedicated directory.
| Category | What it covers | Example forms | Directory |
|---|---|---|---|
| Wire and thermocouple wire | Drawn platinum and platinum-rhodium alloy wire for temperature sensing and resistance elements | Thermocouple wire, resistance wire, fine wire | platinum wire and thermocouple wire suppliers |
| Laboratory labware | Fabricated platinum and platinum-alloy vessels for high-temperature analysis | Crucibles, dishes, gauze | platinum labware suppliers |
| Chemical catalysts | Manufactured and distributed PGM catalysts, industrial and laboratory grade | Supported metal catalysts, homogeneous complexes, sputtering targets | platinum and palladium catalyst suppliers |
Each category page below lists the checks specific to that product form; the checks common to all three follow here.
What to Check Before Ordering PGM Product#
Before ordering from a PGM product supplier, check the purity grade, the accreditation behind it, and how the price is set against the live spot price. A supplier's stated purity, such as 99.95% platinum or a named alloy composition, means only as much as its certificate of analysis, so ask which standard or lab issued that certificate before comparing quotes. Accreditation matters most for wire and labware bought for regulated testing, where a buyer may need traceability to a recognized reference standard rather than a supplier's own in-house assay.
- Purity grade: the stated fineness or alloy composition, backed by a certificate of analysis.
- Accreditation: ISO or an equivalent quality-management certification behind the supplier's own testing.
- Safety data: a current safety data sheet for any compound or catalyst, since several PGM compounds carry GHS hazard classifications.
- Lead time: fabricated product, especially custom wire gauges or vessel sizes, is made to order and rarely held in stock.
- Price basis: whether the quote is fixed at order time or floats with the live PGM spot price until shipment.
| Check item | Why it matters |
|---|---|
| Purity grade | Determines whether the product meets the tolerance a lab or process actually needs |
| Accreditation | Establishes whether the supplier's own testing is independently verifiable |
| Safety data | A current safety data sheet is required before handling most PGM compounds and catalysts |
| Lead time | Custom fabrication is made to order, not shipped from stock |
| Price basis | A quote fixed today can diverge sharply from a quote that floats with spot until shipment |
Price basis is the check most specific to PGMs: PGM products and platinum group metal compounds and catalysts both carry substantial contained-metal value, so a quote that floats with spot until shipment exposes an industrial buyer to the same price movement a bullion buyer sees.
Where This Page Stops: Refiners, Bullion Dealers and Scrap Buyers#
This page covers product suppliers and fabricators, not the refiners that produce the raw sponge or bar, and not the bullion dealers that sell investment coins and bars. The platinum group metal refiners page profiles the accredited refiners that turn ore concentrate or scrap into Good Delivery bar and sponge; this page starts one step downstream, where that refined metal becomes a finished product. Platinum bullion dealers sell coins and bars to individual investors, a retail transaction with no fabrication step, and scrap platinum group metals covers the opposite end of the loop, where used catalytic converters and industrial scrap go back to a refiner, not out to a product buyer.
