1 Kilo UBS Silver Bar

The 1 Kilo UBS Silver Bar

One kilogram is the standard metric bullion weight: 1,000 grams, or 32.1507 troy ounces. This bar is branded by UBS and refined to 999 fine silver, the standard purity for silver bars. The kilo format is bought for one reason above all others: cost per gram. At around $900-$1,000 per bar at current spot prices, kilo silver bars carry premiums of roughly 3-6% over spot, among the lowest available for retail bullion alongside 100 oz bars. Switching from 1 oz units to a kilo bar saves approximately 6% on the silver value, which on a purchase near $1,000 amounts to $50-$70.

Kilo buyers are optimising for the lowest cost per gram rather than flexibility. The trade-off is that the bar is an all-or-nothing sale; partial liquidation is not possible, so an investor who may need to raise small sums is better served by a stack of 10 oz silver bars or 1 oz units. The format is recognised globally and is particularly prevalent in Asian markets such as Singapore and Hong Kong, while in North America the 100 oz bar remains the traditional large silver format.

Physically, a silver kilo bar measures roughly 114mm x 57mm x 13mm depending on the producer and weighs 2.2 lbs. Bars stack neatly in a home safe and are more space-efficient per ounce than the same weight in coins. Silver tarnishes in humid conditions, so storage below 50% relative humidity with desiccant packets is sensible for bare bars.

1 Kilo UBS Silver Bar Specifications

Kilo silver bars are produced in two styles across the market: cast bars, poured into moulds with a chunkier finish and usually lower premiums, and minted bars, which are polished, serialised, and often sealed in packaging. Counterfeit silver bars exist, particularly in larger sizes, though the economics make silver fakes less common than gold. Standard checks are precise weight and dimension measurement, the magnet slide test (silver is diamagnetic), and specific gravity. There is no tungsten-core risk with silver; tungsten is nearly twice as dense, so a substituted core would be obviously overweight. Sealed bars in original packaging resell better than loose ones.

Kilo Silver Bar Tax Treatment by Country

Silver does not enjoy the broad sales tax exemptions that investment gold receives, so country of purchase matters more for a kilo of silver than for the equivalent value of gold.

• UK: 20% VAT on purchase, and no Capital Gains Tax exemption since bars have no legal tender status. This double exposure makes bars the least tax-efficient silver format for UK buyers, though the kilo bar's low premium partly offsets the VAT hit relative to smaller silver.
• EU: Full standard VAT at national rates, from 17% in Luxembourg to 27% in Hungary. Margin scheme relief generally covers pre-owned items rather than new refiner bars.
• US: No federal sales tax; roughly 35 states exempt bullion. A kilo bar's value clears the threshold in partial-exemption states such as New York and Massachusetts ($1,000) and California ($2,000). Long-term gains are taxed at the collectibles rate of up to 28%.
• Canada: GST/HST exempt, as silver refined to 99.9% or higher in bar form qualifies.
• Australia and New Zealand: Investment-grade silver at 99.9% purity is GST-free in both countries, which 999 fine silver meets.
• Singapore and Hong Kong: Singapore exempts qualifying Investment Precious Metals from GST and levies no capital gains tax; Hong Kong has no sales tax of any kind.

Kilo Bar vs 100 oz, 10 oz, and Kilo Coins

The kilo bar's nearest rival is the 100 oz silver bar. A kilo is 32.15 oz, roughly one-third of a 100 oz bar, and premiums on the two formats are similar. The choice is largely regional: the 100 oz bar is the traditional large format in North America, while the kilo is the international standard, dominant in Europe and Asia. The kilo's smaller unit size also makes each sale a more manageable transaction.

Stepping down, the 10 oz bar gives up a little premium efficiency (the marginal saving from 10 oz to kilo is often under 1% per ounce) in exchange for much better divisibility. For most stackers the meaningful premium drop happens between 1 oz and 10 oz; beyond that, each step up saves less, and the kilo makes sense mainly for larger accumulations where small percentages compound.

Brand matters at this weight. The kilo silver market is led by LBMA-accredited refiners including PAMP Suisse, Valcambi, Umicore, Heraeus, Argor-Heraeus, Asahi, the Royal Canadian Mint, and the Perth Mint, whose bars enjoy ready dealer markets worldwide. Bars from names outside that circle trade primarily on metal content and may face wider spreads or assay requests on resale. Kilo silver coins also exist, from the Perth Mint's Lunar, Koala, and Kookaburra ranges and the Royal Mint, but they carry collector premiums above bar prices and suit design-driven buyers rather than cost-focused ones.
