1 oz Ainslie Platinum Bar

The 1 oz Ainslie Platinum Bar in a Thin Market

The 1 oz Ainslie platinum bar contains 31.1035 grams of 999.5 fine platinum, the standard fineness for platinum bars worldwide. One troy ounce is the most commonly traded retail platinum bar size, and for good reason: it sits at the point where premiums become reasonable, typically 5-10% over spot for minted bars, after the very high percentages charged on gram-weight pieces, and before the thin secondary market that affects larger platinum bars.

Platinum is a much smaller bullion market than gold or silver. Fewer refiners produce bars, fewer dealers stock them, and buy-sell spreads run wider than on gold bars in both absolute and percentage terms. That makes the choice of size more consequential than it is for gold. The 1 oz format has the best resale liquidity of any platinum bar; 100g and larger bars may need to be sold to specialist dealers or refiners rather than on the retail market.

Against platinum coins, bars win on price. The premium gap between platinum bars and coins is wider than the equivalent gap in gold, so the saving from choosing a bar is more meaningful here. Coins answer back with sovereign mint branding and, for UK buyers, the CGT exemption on the Platinum Britannia, which no bar can offer. Within platinum bars, the 1 oz size is the practical default for a first position in the metal.

1 oz Ainslie Platinum Bar Specifications

The 999.5 fineness is the industry standard for platinum bars. Platinum is harder to fabricate than gold, with a melting point of 1,768C versus 1,064C, which is one reason platinum bar premiums sit above gold bar premiums at equivalent sizes; lower production volumes and a smaller pool of competing refiners account for the rest.

Authentication is one area where platinum buyers have an easier time than gold buyers. Platinum's density of 21.45 g/cm3 has no cheap look-alike: the only denser candidate metals, iridium and osmium, are rarer and more expensive than platinum itself, and tungsten would be detectably light in a bar of correct dimensions. Counterfeit platinum bars are accordingly rare. The metal also neither tarnishes nor corrodes, so no atmospheric precautions are needed in storage, and its hardness (Mohs 3.5 against gold's 2.5) makes it more resistant to handling scratches. Bars kept sealed in assay packaging from the refiner resell more readily than loose bars.

Tax on 1 oz Platinum Bars by Country

Platinum receives none of the special exemptions reserved for investment gold in Europe, but several countries exempt it alongside other investment-grade metals.

• Canada: 0% GST/HST for platinum at 99.5%+ purity, which this bar meets.
• Australia: 0% GST for investment-grade platinum at 99%+ purity.
• New Zealand: 0% GST for platinum at 99%+ purity.
• Singapore: 0% GST under the Investment Precious Metals scheme for platinum at 99%+ purity; no capital gains tax.
• Hong Kong: No sales tax, no import duty, no capital gains tax.
• UK: 20% VAT on new platinum, and bars are CGT-liable on sale. This double exposure makes bars the least tax-efficient platinum format for UK buyers; the pre-owned margin scheme, where available, reduces the effective VAT to the dealer's margin.
• EU: Full national VAT rates apply, 17-27% depending on the member state.
• US: No federal sales tax; most states exempt bullion. Long-term gains are taxed at the 28% collectibles rate. IRA-eligible platinum must be 99.95%+ purity from an accredited refiner held at an approved depository.
• South Africa: 15% VAT; no exemption for platinum.

The practical upshot: in zero-tax or exempt jurisdictions the bar's lower premium makes it the cheapest route into platinum, whereas UK and EU buyers should price the VAT into any comparison against vaulted or pre-owned alternatives.
