20g Argor-Heraeus Platinum Bar

Swiss-Refined Platinum at a Mid-Range Weight

The 20g Argor-Heraeus platinum bar comes from one of Switzerland's oldest and most respected precious metals refineries. Argor-Heraeus was founded in 1951 in Mendrisio, in the Italian-speaking canton of Ticino, and is now a subsidiary of the German Heraeus Group. The refinery processes approximately 400 tonnes of gold annually and holds LBMA accreditation, a status it shares with fewer than 70 refineries worldwide. It is one of only five refiners serving on the LBMA referee panel, a distinction reserved for the industry's most trusted assayers.

The 20g weight positions this bar in the metric mid-range, containing 0.643 troy ounces of platinum. This is roughly two-thirds of a troy ounce, placing the bar's value in the same bracket as a 1/2 oz product but with 29% more metal content. For buyers in metric markets (continental Europe, Asia, the Middle East), the 20g denomination is a natural choice. In troy-ounce markets, the weight is less conventional but available through dealers who stock Swiss refiner products.

Argor-Heraeus bars are known for clean minted finishes and consistent quality. The refinery also produces an optional Kinebar version of its gold bars, featuring a holographic security element, though platinum Kinebars are less commonly encountered. The standard minted platinum bar carries the Argor-Heraeus hallmark, weight, purity, and serial number in sealed assay packaging.

At the 20g weight, premiums sit between the elevated levels of very small bars (1g-5g at 15-40%+) and the tighter spreads of 1 oz bars (5-10%). Argor-Heraeus pricing is typically competitive with Valcambi and below PAMP Suisse, reflecting the refinery's focus on institutional-quality output rather than brand-premium positioning.

20g Argor-Heraeus Platinum Bar Specifications

The sealed assay packaging contains a certificate of authenticity matching the bar's serial number, and includes the refiner's hallmark and assayer's mark. The tamper-evident design makes any opening visible, preserving the chain of provenance from refinery to buyer. Bars removed from their packaging lose this provenance guarantee and may require independent verification for resale, adding cost and friction to the transaction.

Argor-Heraeus does not currently offer a public digital verification system for serial numbers, unlike PAMP's VeriScan. Authentication relies on physical markings, the sealed assay card, and the refinery's LBMA credentials. Platinum's high density (21.45 g/cm3) provides an inherent counterfeiting deterrent for bars large enough to weigh accurately on a precision scale. The refinery's status as one of only five LBMA referee panel members adds an additional layer of institutional credibility to its products.

Tax Treatment of 20g Argor-Heraeus Platinum Bars

Platinum bars are taxed differently from investment gold in most jurisdictions. The 999.5 purity meets all relevant exemption thresholds where platinum exemptions exist.

• United Kingdom: 20% VAT on purchase. CGT at 18-24% on disposal (GBP 3,000 annual exemption). No CGT exemption since bars lack legal tender status. SIPP-eligible when held by an approved custodian at the required purity.
• United States: Most states exempt investment-grade precious metals from sales tax. IRA-eligible at 99.95% purity from LBMA-accredited refiners. Capital gains taxed at the 28% collectibles rate.
• Canada: GST/HST exempt at 99.5% purity or above.
• Australia: GST-free at 99% purity or above for investment-grade platinum.
• New Zealand: GST-exempt at 99% purity. No capital gains tax.
• Singapore: GST-exempt as IPM at 99% purity from LBMA-accredited refiners. No capital gains tax.
• Hong Kong: No sales tax, no duties, no capital gains tax.
• South Africa: 15% VAT on platinum bullion.
• European Union: Standard VAT rates apply (19-27%). Switzerland applies 8.1% VAT on platinum. Argor-Heraeus bars purchased and stored in Swiss vaults avoid cross-border VAT but still carry Swiss domestic VAT.

Argor-Heraeus 20g vs Other Platinum Bars at This Weight

The 20g platinum bar segment has a handful of branded options, and Argor-Heraeus faces competition from both its Swiss neighbours and from buyers choosing to move up or down in weight.

The 20g Valcambi platinum bar is the most widely available bar at this weight, stocked by the same number of dealers as the generic alternative. Valcambi typically offers the lowest premium among branded Swiss options, and its bars share the same 999.5 purity. For pure cost efficiency, Valcambi is the default choice. Argor-Heraeus offers comparable quality and slightly different distribution channels; some European dealers carry Argor-Heraeus products that they do not stock from Valcambi, and vice versa.

The 20g PAMP Suisse Fortuna platinum bar carries the Lady Fortuna design and commands a brand premium above both Argor-Heraeus and Valcambi. For buyers who value the Fortuna motif and PAMP's VeriScan authentication, the premium is the cost of stronger secondary-market recognition. For those focused on acquiring platinum at the lowest cost per gram, the Argor-Heraeus or Valcambi bars are more practical.

Stepping up to 1 oz platinum bars provides a significant premium improvement. The 1 oz bar (31.1g) contains 55% more platinum than a 20g bar at a lower premium per gram. For buyers who can afford the higher absolute price, the 1 oz weight is more cost-efficient. The 20g bar's value is in its lower price point, giving access to a meaningful quantity of platinum without the commitment of a full troy ounce.
