The IRS minimum fineness for gold bars is .995. Valcambi’s standard bars are .9999, produced by an LBMA Good Delivery-accredited refiner recognized by NYMEX and COMEX. The CombiBar (50×1g format) meets the same fineness criteria but requires custodian confirmation before IRA purchase due to its separable design.
About Valcambi Suisse
Valcambi SA is a Swiss precious metals refiner based in Balerna, Canton Ticino, Switzerland, operating since 1961. The refinery is among the largest in the world by volume, processing gold, silver, platinum, and palladium with an annual capacity approaching 1,400 metric tonnes of precious metals.
Valcambi holds accreditation from the London Bullion Market Association (LBMA) as a Good Delivery refiner for both gold and silver, one of the most demanding quality benchmarks in the global bullion market. The LBMA Good Delivery standard is recognized by NYMEX and COMEX, the major US commodity exchanges, making Valcambi bars acceptable at accredited precious metals facilities worldwide, including US IRS-approved depositories.
The refinery is best known to retail investors for two things: the consistent quality of its minted bars across a full size range (1 gram through 1 kilogram), and the CombiBar, a format introduced in 2012 that bonds 50 individual 1-gram squares into a single sealed unit with perforations between each piece.
Valcambi operates under ISO 9001 (quality management) and ISO 14001 (environmental management) certifications, participates in the LBMA Responsible Gold Guidance, and holds accreditation from the Responsible Jewellery Council (RJC). The refinery is currently owned by Rajesh Exports Ltd, an Indian gold company that acquired it in 2015. This ownership change has not affected Valcambi’s LBMA Good Delivery status or operational standards.
Valcambi Gold Bar Specifications by Size
Valcambi produces minted gold bars across a broad weight range. All standard bars carry a fineness of .9999 (four nines, 24 karat), stamped directly on each bar along with the Valcambi logo, weight, and a unique serial number for authentication. Each bar is sealed in a tamper-evident assay card (certicard) confirming weight and fineness.

The CombiBar: Unique Format, IRA Caveats
Valcambi’s CombiBar is the refinery’s most distinctive product. Introduced in 2012, it consists of 50 individual 1-gram squares bonded together in a single sealed unit, with perforations between each square that allow pieces to be snapped apart like segments of a chocolate bar. The complete unit holds 50 grams of .9999 fine gold (approximately 1.608 troy ounces).
Each individual 1-gram square carries the Valcambi logo, the weight marking (1g), and the fineness (.9999). The full sealed unit includes a certicard confirming the total weight and fineness of the 50-gram block. Dimensions of the complete unit: approximately 79 × 45 × 3.5 mm, roughly the size of a large business card but about 3.5 mm thick.
The CombiBar meets the fineness requirement (.9999 fine) and the refiner requirement (LBMA Good Delivery). However, because it is specifically designed to be separated into individual pieces, some custodians and depositories have specific policies about whether they accept it in sealed form for IRA custody. The concern is practical: a bar designed to be broken into 50 pieces requires clear policies around segregated storage and custody verification when only the full 50-gram unit is the IRA holding.
Confirm CombiBar acceptance with your specific custodian before placing an order. Standard single-piece Valcambi bars (1 oz, 100 g, 1 kg) carry no such complication.
IRS Eligibility: IRC 408(m)(3) Explained
The legal basis for holding physical gold in an IRA comes from IRS Publication 590-B and, more specifically, Internal Revenue Code Section 408(m)(3). The statute permits IRAs to hold two categories of precious metals: certain named coins, and bullion meeting minimum fineness standards.
For bullion bars, IRC 408(m)(3)(B) applies. It allows IRA-held gold bullion that meets the minimum fineness required by NYMEX/COMEX for delivery on a regulated futures contract. For gold, that minimum is .995 fine. Valcambi’s standard bars are .9999 fine, which exceeds this threshold with substantial margin.
The statute also requires the bullion to be produced by a refiner approved by a recognized commodity exchange or accredited by the LBMA. Valcambi holds LBMA Good Delivery status, which satisfies this requirement and is recognized by NYMEX and COMEX.
Two additional IRS rules govern the physical holding of IRA metals:
- No home storage: IRA-held metals must remain in the physical possession of a qualified trustee at an IRS-approved depository. Taking personal possession, even briefly, constitutes a taxable distribution. The Tax Court confirmed this in McNulty v. Commissioner, 157 T.C. No. 10 (2021), striking down home storage arrangements including LLC-based “checkbook IRA” structures.
- Original sealed packaging recommended: Depositories typically require bars to arrive in original manufacturer-sealed assay packaging to facilitate weight and serial number verification. Valcambi’s certicard packaging satisfies this requirement.
Premiums and What They Mean for IRA Holders
The “spot price” of gold is the raw market price per troy ounce for immediate delivery of unallocated gold. When you purchase a minted gold bar, you pay spot plus a dealer premium that covers refinery manufacturing, distribution margin, and packaging. For IRA investors, the premium has a specific implication: it is a real upfront cost, but the IRS values your IRA holdings at spot price, not at what you paid including the premium.
Why the Premium Varies by Bar Size
A 1-gram bar requires nearly the same setup, stamping, and packaging work as a 1-ounce bar, but contains 31 times less gold. The fixed cost per unit is spread across a tiny amount of metal, which is why small fractional bars carry premiums of 20% or more. Conversely, a 1-kilogram bar contains 32 troy ounces of gold, so even a $15 per-unit handling cost translates to under 0.5% of the bar’s total value.
Practical Bar Selection for IRA Accounts
For most self-directed gold IRA accounts, the 1-troy-ounce Valcambi bar is the standard denomination. Premiums of 3 to 6% over spot are competitive with other LBMA-accredited refiners at this size. Investors with larger IRA balances may find 100-gram bars (1.5 to 4% premiums) or kilogram bars more cost-efficient per ounce of gold.
Fractional bars below 10 grams are rarely appropriate for IRA accounts. The premium percentage is high relative to the gold content, and for a tax-advantaged retirement account where the goal is efficient gold exposure, smaller fractional units do not serve that objective well. They are better suited for private physical possession outside an IRA context.
Premium ranges shown are estimates based on typical market conditions and vary by dealer, market volatility, and bar size. Premiums are not fixed and change with supply and demand. Past performance of any investment is not a guarantee of future results.
Where to Acquire Valcambi Bars for Your IRA
Under IRS rules, you cannot purchase gold bars independently and then deposit them into an existing IRA. The purchase must flow through your custodian: you direct funds within the IRA, the custodian authorizes a purchase from an approved dealer, and the dealer ships directly to the IRS-approved depository. You do not handle the bars at any point in the process.
The three companies below are covered by Goldiew user reviews and each offers access to IRS-eligible gold bars from LBMA-accredited refiners. Bar availability by specific refiner can vary by company and market conditions; confirm whether current Valcambi inventory is available during your initial consultation.

Pros and Cons of Valcambi Bars for IRA Holders
- Fully IRA-eligible: .9999 fine, LBMA Good Delivery, satisfies IRC 408(m)(3)(B) without question.
- Global recognition: Accepted at virtually every major depository worldwide, including all major US IRS-approved depositories.
- Wide size range: 1 g through 1 kg, accommodating different account sizes and purchase strategies.
- Sealed assay card: Each bar ships in tamper-evident certicard packaging, simplifying depository acceptance and chain-of-custody verification.
- Competitive premiums on standard sizes: 1-oz bars carry 3 to 6 percent premiums, in line with other top LBMA refiners.
- .9999 purity: Exceeds the IRS minimum of .995; among the highest commercially available gold fineness.
- CombiBar option: Investors who want fractional flexibility within a single custody item can use the CombiBar (subject to custodian confirmation).
- High fractional premiums: 1 g to 10 g bars carry 8 to 40 percent premiums over spot, a meaningful cost disadvantage for IRA investors seeking efficient gold exposure.
- CombiBar custodian step: Requires explicit custodian confirmation before purchase, adding a step compared to standard single-piece bars.
- Less name recognition than US Mint products: Some investors prefer American Gold Eagles or Buffalo coins for familiarity; dealer availability may vary.
- No annual design variation: Unlike national mint coins, Valcambi bars do not feature changing designs, which is irrelevant for pure IRA-holding purposes but noted for completeness.
- Premium not reflected in IRA valuation: Your custodian values holdings at spot; the premium paid represents an upfront cost not recognized in annual account statements.
How to Add Valcambi Bars to Your Existing IRA
The process for purchasing IRS-approved gold bars within a self-directed IRA follows a standard flow. All transactions go through your custodian and an approved dealer; metals ship directly to the depository. You do not handle the bars at any stage.
- Contact a gold IRA specialist to confirm inventory and pricing.
Reach out to one of the companies listed above. Ask specifically whether they carry Valcambi bars in your preferred sizes (1 oz and 100 g are most commonly stocked). Confirm current premiums and lead times. - Identify or open your self-directed IRA.
If you already have a self-directed IRA with an approved custodian, you can direct a purchase within that account. If not, the gold IRA company will assist with opening a new SDIRA. Paperwork typically takes 1 to 5 business days. - Fund the purchase.
Wire funds from your IRA account, or initiate a rollover from an existing 401(k), 403(b), traditional IRA, or other eligible plan. Direct trustee-to-trustee rollovers are not taxable events. Consult your tax advisor before initiating any rollover from a retirement plan. - Confirm CombiBar acceptance if applicable.
If you plan to purchase a CombiBar specifically, confirm in writing with your custodian and depository that they accept it in sealed, unbroken form before placing the order. Standard single-piece bars require no such confirmation step. - The dealer ships directly to the depository.
Once the purchase is authorized, the dealer packages bars in original sealed assay packaging and ships to the IRS-approved depository designated by your custodian. The depository issues a receipt; your IRA account is updated to reflect the new holdings. - Annual statements reflect spot valuation.
Your custodian issues annual statements showing holdings at current spot prices, independent of what you paid in premiums. Retain purchase documentation showing your original cost basis for future reference.
The full process from initial contact to metals arriving at the depository typically takes 4 to 8 weeks, depending primarily on rollover source and custodian paperwork speed.

Alternative IRA-Eligible Gold Bars Worth Comparing
Valcambi is one of several LBMA Good Delivery refiners whose bars satisfy IRC 408(m)(3)(B). Investors sometimes compare refiners based on premium levels at a given dealer, personal preference, or availability through their chosen gold IRA company.
- PAMP Suisse (Swiss, famous for the Lady Fortuna minted bar design): LBMA Good Delivery, .9999 fine, comparable premiums to Valcambi at the 1-oz and 100-g sizes. Widely available through US gold IRA dealers.
- Credit Suisse (historic Swiss bank-branded bars, now produced under license by PAMP): same fineness and LBMA status, strong secondary market recognition in the US market.
- Perth Mint (Australia’s government refinery): LBMA Good Delivery, .9999 fine, competitive premiums on larger sizes. Available through some US gold IRA companies.
- American Gold Buffalo coin (US Mint, .9999 fine, IRA-eligible): a national mint coin alternative for investors who prefer a government-issued product. Available through most US gold IRA companies. See our guide to the best gold IRA companies for providers who carry both bar and coin options.
- American Gold Eagle coin (.9167 fine, the most common IRA gold holding in the US): eligible by specific statutory designation in IRC 408(m)(3)(A) despite lower fineness. Carries higher premiums than .9999 bars of equivalent weight but offers unmatched secondary market liquidity and recognition in the US.
For investors focused solely on IRA-eligible gold exposure, any LBMA Good Delivery bar from a reputable refiner satisfies the IRS requirement equally. Refiner preference between Valcambi, PAMP, Credit Suisse, or Perth Mint is largely a matter of availability and current premium spread at your chosen dealer.

Frequently Asked Questions
Are Valcambi gold bars IRA-eligible?
Yes. All standard Valcambi gold bars are IRA-eligible under IRC 408(m)(3)(B). They are .9999 fine, which exceeds the IRS minimum of .995, and Valcambi is an LBMA Good Delivery-accredited refiner recognized by NYMEX and COMEX. The CombiBar (50×1g) also meets these criteria but requires explicit custodian confirmation before IRA purchase due to its separable format.
What is the minimum fineness for gold bars in an IRA?
Under IRC 408(m)(3)(B), gold bullion held in an IRA must have a fineness of at least .995, the NYMEX/COMEX minimum for regulated futures contract delivery. Valcambi bars at .9999 fine exceed this requirement. The only gold product eligible below .995 is the American Gold Eagle, which is .9167 fine but listed by specific statutory name in IRC 408(m)(3)(A).
Can I hold a Valcambi CombiBar in my gold IRA?
In most cases yes, but you must verify with your specific custodian before ordering. The CombiBar meets the fineness and refiner requirements. The complication is practical: a bar designed to be broken into 50 individual 1-gram pieces requires custodians to establish clear policies around segregated storage accounting for the full sealed unit. Most established custodians accept the CombiBar in original sealed form, but the confirmation step is necessary because policies vary. Standard single-piece Valcambi bars need no such verification.
What is LBMA Good Delivery and why does it matter for IRA eligibility?
The LBMA (London Bullion Market Association) Good Delivery List is the global benchmark for gold and silver refinery accreditation. Refiners on the list meet strict standards for fineness accuracy, bar consistency, chain of custody, and responsible sourcing. NYMEX and COMEX recognize LBMA Good Delivery bars as acceptable for regulated futures delivery, which is the standard IRC 408(m)(3)(B) references for IRA-eligible gold bullion. Valcambi has maintained LBMA Good Delivery status since the early decades of the list, and their bars are accepted at virtually all major US IRS-approved depositories.
Can I store Valcambi bars at home as part of a gold IRA?
No. IRS rules require all IRA-held precious metals to be in the physical possession of a qualified trustee, meaning an IRS-approved custodian using an IRS-approved depository. Storing IRA-held metals at home, in a personal safe, or in a bank safe deposit box in your name constitutes taking personal possession, which triggers a taxable distribution of the full account value. The Tax Court explicitly ruled against home storage IRA arrangements, including LLC-based checkbook IRA structures, in McNulty v. Commissioner, 157 T.C. No. 10 (2021).
Which Valcambi bar size is best for a gold IRA?
For most IRA investors, the 1-troy-ounce bar is the standard choice: it carries a competitive premium of 3 to 6 percent above spot, is widely stocked by US gold IRA dealers, and is accepted at all major depositories. Investors with larger accounts may consider 100-gram bars (premiums of 1.5 to 4 percent) for better cost efficiency per ounce. Fractional bars under 10 grams carry premiums of 8 to 40 percent, which is a significant upfront cost disadvantage for a retirement account focused on efficient gold exposure. Consult your financial advisor for guidance specific to your account size and objectives.
Where is Valcambi located and who owns it?
Valcambi SA is based in Balerna, Canton Ticino, Switzerland, and has been operating since 1961. Since 2015, it has been owned by Rajesh Exports Ltd, an Indian company focused on gold processing and distribution. This ownership change has not affected Valcambi’s LBMA Good Delivery status or product standards. The refinery processes gold, silver, platinum, and palladium, with annual capacity approaching 1,400 metric tonnes of precious metals.
Do Valcambi bars come with a serial number and assay certificate?
Yes. Standard Valcambi minted bars are sealed in an assay card (certicard) that includes the bar’s weight, fineness (.9999), a unique serial number, and Valcambi authentication. The sealed tamper-evident packaging helps IRS-approved depositories verify bar integrity upon receipt. Keeping bars in their original sealed certicard is recommended for IRA holdings and simplifies depository verification at intake. Bars removed from original packaging may face additional verification requirements at the depository.
