100 oz CPG Silver Bar

The 100 oz CPG Silver Bar

The 100 oz CPG Silver Bar contains 100 troy ounces of 999.5 fine silver, a total of 3,110.35 grams. That puts it in the largest standard retail size class for silver bars, a weight that exists for one reason: cost efficiency. The fixed costs of manufacturing, assaying and packaging a bar are spread across 100 ounces, which makes this size the cheapest standard retail route to accumulating physical silver by weight. Premiums on 100 oz bars typically run around 2-4% over spot per ounce, the lowest of any standard retail silver bar size; 1 oz bars often carry 5-10% and 10 oz bars run 3-5%.

The trade-off is divisibility. A 100 oz bar cannot be sold in parts, so realising any of its value means finding one buyer for the full amount, roughly 3.1 kg of silver in a single piece. Accumulators building larger silver positions accept that constraint in exchange for the premium savings; buyers who expect to sell incrementally are usually better served by 10oz silver bars or 1 oz products.

The 100 oz weight is a standard unit of trade in the North American silver market, where every major bullion dealer buys and sells bars of this size. It is less standard elsewhere: European and Asian retail markets prefer metric weights such as the kilo bar. At 999.5 fineness, the CPG bar slightly exceeds the .999 standard that most silver bars in this weight class carry, which matters for the purity thresholds some tax regimes set at 99.9%.

100 oz CPG Silver Bar Specifications

At 3,110.35 grams, the bar weighs about 3.11 kg (6.86 lbs). Exact dimensions vary by manufacturer in this weight class, but 100 oz silver bars typically measure roughly 140mm x 80mm x 25mm, a footprint comparable to a large smartphone but far heavier. The rectangular form stacks readily, and a single bar fits in a home safe or safe deposit box, though stacking multiples adds weight quickly.

The 999.5 fineness is a step above the .999 standard common across silver bars and clears the 99.9% silver purity thresholds used by several tax regimes, including Australia's GST exemption and New Zealand's GST exemption. There is no standard tube or roll packaging at this weight; 100 oz bars are sold individually, sometimes in protective plastic sleeves. As a bar rather than a coin, it carries no face value and no legal tender status, which has tax consequences in the UK covered under the Tax tab.

100 oz CPG Silver Bar Tax Treatment by Country

Silver bars do not benefit from the investment-gold exemptions that apply in the UK and EU, so tax treatment varies sharply by country. The 999.5 fineness matters here: several exemptions set their silver threshold at 99.9% purity, which this bar clears.

• UK: 20% VAT on new silver bullion. Bars are also subject to Capital Gains Tax on disposal (no legal tender status), making silver bars the least tax-efficient silver form for UK investors.
• EU: Full local VAT rate applies to new silver, ranging from 17% to 27% depending on the member state. Margin schemes in countries such as Germany and the Netherlands apply to pre-owned silver, not new bars from refiners.
• US: No federal sales tax; state rules vary, and most states exempt bullion bars. Long-term capital gains are taxed at the collectibles rate of up to 28%. IRA eligibility for silver requires 99.9%+ purity from accredited refiners.
• Canada: 0% GST/HST for silver refined to 99.9%+ purity in bar form, which this bar exceeds.
• Australia: GST-free as investment-grade silver (99.9%+ purity threshold met).
• New Zealand: GST-exempt as fine bullion (silver 99.9%+ purity). No formal capital gains tax.
• Singapore: 0% GST under the Investment Precious Metals scheme for silver of 99.9%+ purity in bar form. No capital gains tax.
• Hong Kong: No sales tax, no import duty, no capital gains tax.
• South Africa: Full 15% VAT on silver bullion; the zero-rating that covers gold Krugerrands does not extend to silver.

100 oz CPG Bar vs RCM, 10 oz Bars and Kilo Bars

The most direct alternative at this weight is the 100 oz Royal Canadian Mint silver bar. The RCM bar is .9999 fine, serialised, and produced by an LBMA Good Delivery listed government mint. Brand recognition matters most at resale: bars from LBMA-accredited refiners such as RCM and Asahi command tighter buyback spreads, while bars from lesser-known producers can face wider discounts and may sell closer to melt value. Most dealers will weigh, measure or assay a secondary-market 100 oz bar before buying it regardless of brand, an extra step that coins with known specifications avoid. On purity, the CPG bar's 999.5 fineness sits between the .999 standard and RCM's .9999, and all three clear the 99.9% thresholds that matter for GST exemptions in Australia, New Zealand and Singapore.

Down the weight scale, 10oz silver bars are the usual counterargument. They carry premiums of roughly 3-5% against 2-4% for 100 oz bars, so the marginal saving from stepping up is smaller than the jump from 1 oz to 10 oz. What the smaller bar buys is flexibility: ten 10 oz bars can be sold one at a time, while a 100 oz bar needs a single buyer for the whole amount.

The other alternative is the kilo bar at 32.15 oz, the international standard size for retail silver and the preferred format in Europe, Asia and Australia. Buyers in those markets may find kilo bars easier to resell locally, whereas the 100 oz format is the established standard in North America. For maximum silver weight per dollar in a single piece, the 100 oz size remains the most cost-efficient standard retail option.
