400 oz PAMP Suisse Gold Bar

The Institutional Standard: A 400 oz LBMA Good Delivery Bar from PAMP Suisse

The 400 oz PAMP Suisse gold bar is an LBMA Good Delivery bar, the institutional standard used to settle trades on the London bullion market. At approximately 12.44 kilograms (400 troy ounces), this is the bar format held by central banks, sovereign wealth funds, and gold ETFs. It is not a typical retail product. Buyers at this level are institutional investors, wealth management clients, or high-net-worth individuals making substantial single allocations to physical gold.

PAMP Suisse (Produits Artistiques Metaux Precieux) was founded in 1977 in Ticino, Switzerland and is now part of the MKS PAMP Group. PAMP has held LBMA Good Delivery accreditation since the refinery's early years, and its 400 oz bars are accepted without further assay by LBMA member vaults, central banks, and commodity exchanges worldwide. The LBMA Good Delivery specification requires a minimum fineness of 995, though PAMP's bars are refined to 999.9 fine gold as standard.

At current gold prices, a single 400 oz bar represents a value exceeding $4 million. The premium above spot on bars of this size is minimal, typically well under 1%, reflecting the near-wholesale pricing available at the institutional level. This is as close to trading gold at spot price as a physical buyer can get. The trade-off is total indivisibility: selling means liquidating the entire bar at once, and the buyer pool is limited to institutions and refiners equipped to handle Good Delivery bars.

PAMP is best known in the retail market for its Lady Fortuna minted bars, but the 400 oz Good Delivery bar is a different product entirely. It is a cast bar with no decorative design, carrying only the PAMP name, weight, purity, serial number, and assay mark. The focus is on conforming precisely to LBMA specifications, not on visual appeal.

400 oz PAMP Suisse Good Delivery Bar Specifications

The LBMA Good Delivery standard specifies not just purity and weight but also physical dimensions, surface quality, and marking requirements. Each bar must bear the refiner's mark, a serial number, the fineness expressed to four significant figures, and the year of manufacture. The actual weight of an individual bar may fall anywhere in the 350-430 oz range; the bar is traded by its exact assayed weight, not a rounded nominal figure. This variable weight is a feature of the Good Delivery system rather than a manufacturing tolerance.

Good Delivery bars are the settlement mechanism for the London over-the-counter gold market and for COMEX futures contracts, which allow delivery in both 100 oz and 400 oz bar formats. When gold ETFs such as SPDR Gold Trust (GLD) report their holdings, those holdings typically consist of Good Delivery bars stored in LBMA-approved vaults. PAMP Suisse is one of the refiners whose bars are accepted into these systems without further assay, reflecting the strength of its LBMA accreditation.

Tax Treatment of the 400 oz PAMP Suisse Gold Bar

The tax treatment of a 400 oz Good Delivery bar is identical in principle to any other investment gold bar at 995+ fineness, though the practical context differs. Bars of this size are typically held in professional vault storage, purchased through institutional channels, and may be subject to different reporting thresholds.

Purchase Tax

• United Kingdom: VAT-free as investment gold at 995+ fineness.
• European Union: VAT-exempt under EU Directive 98/80/EC.
• United States: No federal sales tax. State-level varies. At this value level (over $4 million), all threshold-based state exemptions are comfortably exceeded.
• Switzerland: No VAT on investment gold. PAMP bars purchased and stored in Swiss vaults benefit from Switzerland's favourable storage and tax environment.
• Singapore: GST-exempt under the Investment Precious Metals scheme.
• Hong Kong: No sales tax or import duties.
• Canada: GST/HST exempt for gold at 99.5%+ purity.
• Australia: GST-free for investment gold at 99.5%+ purity.

Capital Gains and Reporting

• US: Taxed as a collectible at a maximum 28% long-term rate. At this transaction size, IRS reporting is mandatory. Form 1099-B applies to sales exceeding certain thresholds.
• UK: Subject to CGT. No legal tender exemption for bars. At this value, the £3,000 annual allowance is negligible relative to potential gains.
• Switzerland: No capital gains tax for individuals on personal property (including gold held privately). This makes Swiss vault storage attractive for substantial holdings.
• Hong Kong and Singapore: No capital gains tax in either jurisdiction.

400 oz PAMP Suisse vs Other Good Delivery Bars

At the 400 oz Good Delivery level, the comparison between refiners is less about brand prestige and more about liquidity, acceptance, and practical sourcing. All LBMA Good Delivery bars are, by definition, interchangeable within the LBMA vaulting and trading system. A 400 oz bar from PAMP, Metalor, Argor-Heraeus, or any other accredited refiner is accepted on identical terms.

The 400 oz Republic Metals Corporation bar is a notable comparison case. Republic Metals Corporation, a Miami-based refinery, filed for bankruptcy in 2018, and its refining assets were acquired by Asahi Refining in 2019. RMC bars that were produced before the bankruptcy remain in circulation and are valid LBMA Good Delivery bars. They trade at the same terms as any other Good Delivery bar, but the defunct status of the original refiner may give some buyers pause, even though the bar's intrinsic gold content and LBMA status are unaffected.

Swiss-refined 400 oz bars from PAMP, Argor-Heraeus, and Metalor carry the strongest brand recognition in institutional markets, partly due to Switzerland's centuries-long association with precious metals refining and banking. PAMP's position as part of the MKS PAMP Group, a vertically integrated precious metals company spanning mining, refining, and financial services, adds a dimension of supply-chain depth that standalone refiners cannot match.

For buyers considering a 400 oz bar as a long-term store of wealth, the refiner brand matters less than the LBMA accreditation itself. The Good Delivery system ensures that any accredited bar can be sold into the London market, delivered against a COMEX futures contract, or deposited into an ETF vault without friction. The choice between PAMP and another refiner at this level is primarily about availability and the specific dealer relationship.
