The IRS minimum fineness for gold bars is .995. Argor-Heraeus standard bars are .9999, produced by an LBMA Good Delivery-accredited Swiss refiner recognized by NYMEX and COMEX. The KineBar uses a Kinegram optical security feature that does not affect IRA eligibility, since the underlying bar still meets the fineness and refiner accreditation requirements.
About Argor-Heraeus
Argor-Heraeus SA is a Swiss precious metals refiner based in Mendrisio, Canton Ticino, Switzerland. The refinery traces its origins to 1951 with the founding of Argor SA, and adopted the Argor-Heraeus name following a long partnership with the German precious metals group Heraeus that culminated in the joint brand identity used today.
The refinery is among the four major Swiss gold refiners alongside PAMP, Valcambi, and Metalor. Argor-Heraeus holds accreditation from the London Bullion Market Association (LBMA) as a Good Delivery refiner for gold and silver, the most demanding standard in the global bullion market. The LBMA Good Delivery standard is recognized by NYMEX and COMEX, the major US commodity exchanges, which makes Argor-Heraeus bars acceptable at IRS-approved precious metals depositories used by US self-directed IRA custodians.
Argor-Heraeus operates under ISO 9001 (quality management) and ISO 14001 (environmental management) certifications, participates in the LBMA Responsible Gold Guidance, and adheres to the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas. The refinery processes gold, silver, platinum, and palladium for industrial, jewelry, and investment customers worldwide.
For retail investors, Argor-Heraeus is best known for two product lines: standard minted bars across a full size range (1 gram through 1 kilogram), and the KineBar, a line of investment bars that integrate an optical Kinegram security feature on the bar surface for counterfeit deterrence. Each bar carries the Argor-Heraeus hallmark, weight, fineness, and a unique serial number, and ships sealed in a tamper-evident assay card.
Argor-Heraeus Gold Bar Specifications by Size
Argor-Heraeus 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 Argor-Heraeus hallmark, weight, and a unique serial number for authentication. Each bar is sealed in a tamper-evident assay card confirming weight, fineness, and serial.

Dimensions shown are typical for minted Argor-Heraeus bars; small variations can occur between production batches. Cast bars in the 1 kg size are also produced and follow the same fineness and accreditation standards as the minted versions, with slightly different physical dimensions and a lower premium relative to minted bars.
The KineBar: Hologram Security Explained
Argor-Heraeus is among the small group of refiners that integrate an optical security feature on the surface of investment-grade gold bars. The KineBar uses a Kinegram, a diffractive optical variable image device originally developed by OVD Kinegram AG of Switzerland for use on banknotes, identity documents, and high-security goods. The Kinegram embedded on the KineBar surface shifts color and motion patterns when tilted under direct light, a property that is extremely difficult to replicate with conventional counterfeit techniques.
The hologram is bonded into the bar surface during manufacturing and remains visible on the front face along with the standard Argor-Heraeus hallmark, weight marking, fineness stamp, and serial number. KineBars are produced primarily in the 1 g, 5 g, 10 g, 20 g, 1 oz, 50 g, and 100 g sizes, with availability varying by dealer and market region.
KineBar vs Other Hologram-Protected Investment Bars
Argor-Heraeus is not the only refiner that uses optical security technology on investment bars. PAMP Suisse uses its proprietary Veriscan and CertiPAMP technology on Lady Fortuna minted bars, also produced in Switzerland. From an IRA eligibility standpoint, both manufacturers satisfy IRC 408(m)(3)(B) equally; the choice between them is typically determined by dealer availability, current premium spread, and aesthetic preference.
IRS Eligibility: IRC 408(m)(3) Explained
The legal basis for holding physical gold in an IRA comes from IRS Publication 590-B and 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. Argor-Heraeus standard bars are .9999 fine, exceeding this threshold with substantial margin.
The statute also requires the bullion to be produced by a refiner accredited by a recognized commodity exchange or by the LBMA. Argor-Heraeus holds LBMA Good Delivery status for gold, 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 at intake. Argor-Heraeus assay card 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, packaging, and any optical security features (KineBar carries a small additional premium). 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 percent or more. Conversely, a 1-kilogram bar contains 32 troy ounces of gold, so even a 15 dollar per-unit handling cost translates to under 0.5 percent of the bar’s total value.
Practical Bar Selection for IRA Accounts
For most self-directed gold IRA accounts, the 1-troy-ounce Argor-Heraeus bar is the standard denomination. Premiums of 3 to 6 percent over spot are competitive with other LBMA-accredited Swiss refiners at this size. Investors with larger IRA balances may find 100-gram bars (1.5 to 4 percent 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 Argor-Heraeus 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 Swiss refiners. Bar availability by specific refiner can vary by company and market conditions; confirm whether current Argor-Heraeus inventory (standard bars or KineBars) is available during your initial consultation.

Pros and Cons of Argor-Heraeus Bars for IRA Holders
- Fully IRA-eligible: .9999 fine, LBMA Good Delivery, satisfies IRC 408(m)(3)(B) without question.
- Global recognition: Accepted at all major US IRS-approved depositories and at LBMA depositories worldwide.
- Wide size range: 1 g through 1 kg, accommodating different account sizes and purchase strategies.
- KineBar hologram security: Optical Kinegram feature provides a strong counterfeit-deterrent layer that does not affect IRA eligibility.
- Sealed assay card: Each bar ships in tamper-evident assay packaging with weight, fineness, and unique serial, 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 Swiss refiners.
- .9999 purity: Exceeds the IRS minimum of .995; among the highest commercially available gold fineness.
- 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.
- KineBar premium: The Kinegram security feature adds roughly 1 to 3 percent to the bar premium versus the standard equivalent, an upfront cost not reflected in IRA spot valuation.
- Less name recognition than US Mint products: Some investors prefer American Gold Eagles or Buffalo coins for familiarity; dealer availability of Argor-Heraeus inventory may vary.
- No annual design variation: Unlike national mint coins, Argor-Heraeus 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 Argor-Heraeus 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 Argor-Heraeus bars in your preferred sizes (1 oz and 100 g are most commonly stocked). If you want a KineBar, confirm availability separately, since KineBar inventory rotates faster than standard bars. 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 KineBar acceptance if applicable.
KineBars are accepted at all major IRS-approved depositories because the underlying bar meets every standard requirement. Some custodians flag the Kinegram feature in their intake notes for visual verification. If you plan to purchase a KineBar specifically, the dealer or custodian can confirm acceptance during your initial consultation. - 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
Argor-Heraeus 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, security feature preference, or availability through their chosen gold IRA company.
- PAMP Suisse (Swiss, famous for the Lady Fortuna minted bar design with Veriscan security): LBMA Good Delivery, .9999 fine, comparable premiums to Argor-Heraeus at the 1-oz and 100-g sizes. The most widely available Swiss refiner brand at US gold IRA dealers.
- Valcambi Suisse (Swiss, also produces the unique CombiBar): LBMA Good Delivery, .9999 fine. Wide retail availability and a similar premium profile.
- Perth Mint (Australia’s government refinery): LBMA Good Delivery, .9999 fine, competitive premiums on larger sizes. Available through some US gold IRA companies.
- Royal Canadian Mint (Canadian government refinery): LBMA Good Delivery, .9999 fine. RCM bars carry the Maple Leaf hallmark and are widely available in the US dealer network.
- 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.
- 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 strong 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 Argor-Heraeus, PAMP, Valcambi, or Perth Mint is largely a matter of availability, security feature preference (Kinegram vs Veriscan), and current premium spread at your chosen dealer. For a broader comparison of gold IRA providers and the products they carry, see the Goldiew best gold IRA companies guide and the LBMA refiner list for IRA-eligible bars.
Frequently Asked Questions
Are Argor-Heraeus gold bars IRA-eligible?
Yes. All standard Argor-Heraeus gold bars are IRA-eligible under IRC 408(m)(3)(B). They are .9999 fine, exceeding the IRS minimum of .995, and Argor-Heraeus is an LBMA Good Delivery-accredited Swiss refiner recognized by NYMEX and COMEX. The KineBar variant (with Kinegram hologram security feature) is equally eligible because the underlying bar meets the same fineness and refiner accreditation standards.
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. Argor-Heraeus 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).
Is the KineBar IRA-eligible, and what does the hologram do?
Yes. The KineBar is .9999 fine and produced by Argor-Heraeus, which is LBMA Good Delivery accredited. That satisfies IRC 408(m)(3)(B). The Kinegram on the bar surface is a diffractive optical security feature originally developed by OVD Kinegram AG for use on banknotes and identity documents. It shifts color and motion under tilted light, which is difficult to counterfeit. It is a security feature, not an IRA eligibility criterion. KineBars typically carry a 1 to 3 percent premium over standard Argor-Heraeus bars of the same weight.
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. Argor-Heraeus holds LBMA Good Delivery accreditation, and their bars are accepted at all major US IRS-approved depositories.
Can I store Argor-Heraeus 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 Argor-Heraeus 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 Argor-Heraeus located and what is its history?
Argor-Heraeus SA is based in Mendrisio, Canton Ticino, Switzerland. The refinery traces its origins to 1951 with the founding of Argor SA in Switzerland, with the Argor-Heraeus brand reflecting a long-standing partnership with the German precious metals group Heraeus. It is one of the four major Swiss precious metals refiners alongside PAMP, Valcambi, and Metalor. The refinery processes gold, silver, platinum, and palladium for industrial, jewelry, and investment customers worldwide.
Do Argor-Heraeus bars come with a serial number and assay certificate?
Yes. Standard Argor-Heraeus minted bars are sealed in an assay card that includes the bar’s weight, fineness (.9999), a unique serial number, and Argor-Heraeus hallmark authentication. The sealed tamper-evident packaging helps IRS-approved depositories verify bar integrity upon receipt. Keeping bars in their original sealed assay card is recommended for IRA holdings and simplifies depository verification at intake. Bars removed from original packaging may face additional verification requirements at the depository.
How does Argor-Heraeus compare to PAMP Suisse for an IRA?
Both are LBMA Good Delivery-accredited Swiss refiners producing .9999 fine investment bars. Both satisfy IRC 408(m)(3)(B) and are accepted at all major US IRS-approved depositories. PAMP Suisse is more widely stocked at US dealers and is known for the Lady Fortuna design with Veriscan and CertiPAMP security technology. Argor-Heraeus is known for the KineBar with Kinegram hologram security. Premium pricing on 1-ounce bars is typically comparable between the two. The choice often comes down to current dealer availability and personal preference for the security feature design.
