100 oz Heraeus Silver Bar

The 100 oz Heraeus Silver Bar

This bar pairs the lowest-premium silver bar format with one of the oldest names in precious metals refining. Heraeus was founded in Hanau, Germany in 1851, remains a privately held family company, and its German refinery holds LBMA Good Delivery accreditation for silver. Heraeus bars carry the company's coat of arms, a hand with roses, derived from a family crest dating back to Isaac Heraeus in the 17th century. That pedigree matters at this size: brand recognition is what keeps buyback spreads tight on large bars.

The 100 troy ounce weight, roughly 3.11 kilograms of 999 fine silver, exists to minimise cost per ounce. Premiums typically run 2 to 4 percent over spot, the lowest of any standard retail silver bar size, because the fixed costs of refining, assaying and packaging are spread across a hundred ounces. By comparison, 10 oz silver bars run 3 to 5 percent and 1 oz bars often 5 to 10 percent or more.

The format is most at home in North America, where the 100 oz bar is a standard unit of silver trade; European and Asian markets prefer metric kilo bars. The bar is also indivisible, so selling means finding one buyer for the whole position. For accumulators building large silver holdings who want a recognised LBMA refiner behind every ounce, this is one of the most efficient routes available.

100 oz Heraeus Silver Bar Specifications

999 fineness is the standard for the 100 oz weight class. Physically, bars of this size measure roughly 140mm by 80mm by 25mm and weigh about 6.86 pounds, a footprint comparable to a large smartphone but far denser. The rectangular form stacks cleanly, though multiples add weight to a safe quickly.

Heraeus has refined precious metals since the mid-19th century, with gold refining capacity of roughly 400 to 500 tonnes a year across its Hanau and Hong Kong facilities and four trading desks worldwide. For verification of a bar this size, standard silver checks apply: precise weight and dimensions, the magnet slide test and specific gravity. There is no tungsten-core risk with silver, as any substitute metal is light enough to fail a weight check.

Tax Treatment of the 100 oz Heraeus Silver Bar

Silver lacks gold's broad sales tax exemptions, so jurisdiction shapes the real cost of a bar this large.

• UK: 20% VAT on purchase, and bars carry CGT on disposal since they are not legal tender. On a 100 oz purchase the VAT alone is substantial, which is why this format suits UK buyers far less than American ones.
• EU: Full local VAT on new silver bars, 17 to 27 percent depending on the member state; Germany's margin scheme covers pre-owned silver only.
• US: No federal sales tax; around 35 states exempt bullion entirely, and the threshold states (New York and Massachusetts at $1,000, California at $2,000) are cleared at this bar's value. Long-term gains are taxed at the 28 percent collectibles rate. 100 oz bars from LBMA-accredited refiners meeting the .999 fineness requirement are accepted by IRA custodians.
• Canada: 0% GST/HST, as 99.9 percent purity clears the federal 99.9 percent threshold.
• Australia and New Zealand: 0% GST for silver at 99.9 percent purity or better.
• Singapore and Hong Kong: No GST or sales tax on qualifying investment silver and no capital gains tax in either jurisdiction.

Heraeus vs the Other 100 oz Names, and vs Smaller Bars

The 100 oz silver bar market splits into current production from LBMA-accredited refiners and a secondary market of discontinued names. The Royal Canadian Mint bar is the purity outlier at .9999 fine with serial numbers; Asahi Refining continues the line of business it acquired from Johnson Matthey in 2015; and the discontinued Johnson Matthey and Engelhard bars trade at a collector premium driven by brand nostalgia rather than metal content. Sunshine Minting, Republic Metals and Ohio Precious Metals occupy the generic tier. A Heraeus bar sits naturally alongside the accredited names: recognised by dealers globally, with buyback spreads from major dealers typically 1 to 3 percent below spot for established brands.

Against smaller formats, the case for the 100 oz bar is pure cost. The biggest premium drop on the silver size ladder happens between 1 oz and 10 oz, and the step from 10 oz to 100 oz adds a smaller but still real saving. The price of that efficiency is flexibility: a 10 oz Royal Canadian Mint bar stack can be sold piecemeal, a 100 oz bar cannot. Dealer guidance generally points buyers building 500 oz or larger positions towards the 100 oz format and occasional buyers towards smaller bars.

The kilo bar (32.15 oz) is the other large-format rival, with similar per-ounce premiums and better recognition in Europe, Asia and Australia. For a buyer in North America, the 100 oz Heraeus is the more conventional trade; elsewhere, kilo bars from the same refiner tier may exit more smoothly.
