Quick answer: PAMP Suisse platinum bars are IRA-eligible. They are refined at .9995 fine, which meets the IRS fineness minimum for platinum bullion in Internal Revenue Code section 408(m)(3)(B). PAMP is on the London Platinum and Palladium Market Good Delivery list, and its bars are accepted by the depositories most self-directed IRA custodians settle to.
Standard investment sizes run from 1 gram to 1 kilogram, with the 1 troy ounce cast bar the most common ticket size for a retirement account. The metal must ship directly from the dealer to an IRS-approved depository. Nothing on this page is financial or tax advice.
Short on time? The essentials
- PAMP Suisse platinum bars are refined at .9995 fine and satisfy the fineness route into an IRA under IRC section 408(m)(3)(B).
- PAMP is a Swiss refiner on the London Platinum and Palladium Market Good Delivery list, which is the delivery standard most custodians look for on a platinum order.
- Standard investment sizes are 1 g, 5 g, 10 g, 20 g, 1 oz, 50 g, 100 g, 10 oz, and 1 kg. The 1 troy ounce cast bar is the most common IRA order size.
- Minted bars ship in the CertiPAMP tamper-evident assay card. Cast bars carry the serial number and refiner stamp directly on the bar and a paper assay from the refiner.
- Premium over the platinum reference price varies by size. Fractional bars carry a wider premium per ounce than the 1 oz bar because manufacturing cost is spread over less metal.
- Compared with the Platinum American Eagle, a PAMP 1 oz bar often prices at a lower premium, though product depth on platinum bars is thinner than on coins.
- Delaware Depository, International Depository Services, and Brink's Global Services all recognize PAMP Suisse as an accepted refiner for IRA platinum.
- You never handle the bar personally while it sits inside an IRA. The custodian wires funds and the depository takes physical possession under the trustee arrangement.
Answer at a glance
This page answers a narrow question: are PAMP Suisse platinum bars eligible for a self-directed IRA, and in which sizes. The short answer is yes on eligibility, in every current investment size the refiner produces, from 1 gram through 1 kilogram. Everything below explains why the answer holds and where a buyer can still make a costly mistake on the intake call.
PAMP is a Swiss refiner accredited under the delivery standard the tax statute points to for platinum bullion. Its bars meet the fineness minimum, ship with third-party assay documentation, and are already on the accepted-refiner rosters at the major precious-metals depositories. Nothing on this page is a price forecast, and nothing here is personal financial or tax advice.
PAMP Suisse: refiner credentials that matter for an IRA
PAMP is short for Produits Artistiques Métaux Précieux, a refiner founded in 1977 and based in the Swiss canton of Ticino. The company operates as part of the MKS PAMP Group, which combines refining, minting, and physical trading. For a retirement account, three pieces of the refiner file matter more than the brand story: the accreditation, the fineness standard, and the assay documentation that ships with the bar.
PAMP is on the London Platinum and Palladium Market (LPPM) Good Delivery list, which is the physical-market benchmark for wholesale platinum bars. Its gold and silver production also sits on the London Bullion Market Association (LBMA) Good Delivery list. The LPPM list is the platinum equivalent of the LBMA list that the London and other bullion markets use to define wholesale bars (source: LBMA Good Delivery, checked June 2026).
Delivery-list membership is not the same as IRS eligibility, but it settles two questions custodians ask on every platinum order. First, whether the refiner meets a "commodity market" delivery standard, which is the phrase the tax statute uses in IRC section 408(m)(3)(B) (source: 26 U.S.C. section 408(m)). Second, whether the depository will accept the specific bar without a fresh assay when it arrives.
Refiner accreditation and coin-mint pedigree solve different problems. The Platinum American Eagle qualifies because the coin is issued under 31 U.S.C. section 5112 and admitted through the IRS carve-out at 408(m)(3)(A). A PAMP bar qualifies because it clears the fineness route at 408(m)(3)(B). Two different doors, same regulation.
Which IRS route admits a PAMP platinum bar
The tax statute lays out two routes for platinum to sit inside an IRA. A PAMP Suisse platinum bar walks through the second route, the fineness test.
- Route A: the coin carve-out. Section 408(m)(3)(A) admits coins issued under 31 U.S.C. section 5112. The Platinum American Eagle qualifies through this route. PAMP does not mint sovereign coins, so the coin route does not apply to its bars.
- Route B: the fineness test. Section 408(m)(3)(B) admits platinum bullion at a fineness "equal to or exceeding the minimum fineness that a contract market" requires for a regulated futures contract. For platinum, the referenced standard is .9995. PAMP Suisse platinum bars are refined at .9995 fine and pass this test.
Both routes still require the metal to be in "the physical possession of a trustee described under subsection (a)" (source: 26 U.S.C. section 408(m)). That trustee is a bank or an IRS-approved non-bank trustee. The IRS restates the same rule in its collectibles Issue Snapshot (source: IRS Investments in Collectibles Issue Snapshot). A PAMP bar sitting in your safe at home fails that possession test even though the bar itself is eligible bullion.

Sizes, weights, and formats
PAMP produces platinum in two main formats. Minted bars are pressed from cast blanks, carry the signature Lady Fortuna design on the obverse, and ship inside the tamper-evident CertiPAMP assay card. Cast bars are poured, carry the PAMP logo and serial number stamped directly on the bar, and ship with a separate paper assay certificate from the refiner. Both formats are eligible under section 408(m)(3)(B) at the same .9995 fineness.
The size range for platinum is narrower than for gold, and premiums per ounce fall as the bar gets larger. Most self-directed IRA orders sit in the 1 troy ounce or 10 troy ounce band, because those sizes balance premium per ounce against divisibility for a partial future sale.
| Nominal size | Weight (grams) | Typical format | IRA-eligible at .9995 |
|---|---|---|---|
| 1 g | 1 g | Minted, CertiPAMP card | Yes |
| 5 g | 5 g | Minted, CertiPAMP card | Yes |
| 10 g | 10 g | Minted, CertiPAMP card | Yes |
| 20 g | 20 g | Minted, CertiPAMP card | Yes |
| 1 troy oz | 31.10 g | Minted or cast | Yes |
| 50 g | 50 g | Minted or cast | Yes |
| 100 g | 100 g | Cast with paper assay | Yes |
| 10 troy oz | 311.03 g | Cast with paper assay | Yes |
| 1 kg | 1,000 g | Cast with paper assay | Yes |

Not every dealer stocks every size, and platinum bar availability tightens when refinery output shifts. Ask the dealer for the specific size, format, and refiner in writing before wiring funds. A custodian will settle only against the exact product on the confirmation, not a "similar" substitute delivered later.
Premium band: bars versus platinum coins
Premium is the gap between the dealer's ask price and the reference platinum spot price on the day. It funds refining, minting, packaging, dealer inventory, and the dealer margin. Premium is usually the single largest lifetime cost of a physical-metal IRA order, and it varies by product, by size, and by day.
Three structural points hold across most days on the market. Fractional bars, the 1 gram through 10 gram range, carry the widest premium per troy ounce because manufacturing cost is spread over less metal. The 1 troy ounce bar sits in the middle. Larger bars, 10 oz and 1 kg, carry the tightest premium per ounce but are less divisible when you eventually sell part of the position.
Against coins, a PAMP 1 oz platinum bar usually prices at a lower premium than the same weight in Platinum American Eagles or Canadian Platinum Maple Leafs. The premium gap swings with dealer inventory, coin-mint output, and platinum market volumes. Product depth is the other side of the coin. Sovereign coins move in higher daily volumes than any single refiner's platinum bar, which can mean a slightly tighter buy-back spread on the coin at sale time.
Ask for four numbers on the specific PAMP platinum bar you plan to buy: the dealer ask as a percentage over the reference spot price, the same-day buy-back bid the dealer would pay for that exact bar, the depository ship-to on the invoice, and the custodian on file. If any of the four is missing, the order is not ready to sign.
To compare against the alternative products a custodian will accept, see IRA-eligible platinum coins and bars. For a walkthrough of how the dealer, custodian, and depository split the work on a single order, see platinum IRA explained.
How the bar reaches the vault, and stays there
Three parties move a PAMP Suisse platinum bar from a dealer to your IRA. The custodian holds legal title, confirms available cash, wires funds, and books the bar to your account. The dealer sources the specific bar, quotes a locked price, and ships directly to the depository.
The depository is an IRS-approved facility. It takes physical possession under the trustee arrangement and reports the serial number and assay back to the custodian.
You never take personal possession of the bar during that chain. Doing so would trigger a deemed distribution under section 408(m), taxed at the metal's fair market value, plus the 10 percent additional tax if you are under 59.5 (source: IRS Publication 590-B). The United States Tax Court applied section 408(m) against the taxpayers in McNulty v. Commissioner, 157 T.C. 10 (2021), on a home-storage arrangement for IRA-owned bullion. That decision stands.
Widely used depositories in the sector include Delaware Depository in Wilmington, Delaware; International Depository Services in New Castle, Delaware and in Texas; and Brink's Global Services, with United States precious-metals vaults in New York, Salt Lake City, and Los Angeles. All three recognize PAMP Suisse as an accepted refiner for platinum. Confirm which vault your custodian settles to before you sign anything, because a mismatched ship-to on the dealer invoice is the most common cause of a delayed settlement.
| Party | Handles | Cannot do |
|---|---|---|
| Self-directed IRA custodian | Holds legal title, confirms cash, releases the wire, books the bar to your IRA, files Form 5498 | Cannot select the bar for you, cannot store the bar on its own premises unless it is also an approved depository |
| Precious-metals dealer | Sources the specific PAMP bar, quotes a locked price, issues the invoice, ships to the depository | Cannot hold your IRA cash, cannot store the bar for you, cannot deliver the bar to your home |
| IRS-approved depository | Takes physical possession, logs the serial number and assay, confirms receipt to the custodian | Cannot release the bar to you personally while it stays inside the IRA, cannot buy or sell on your behalf |

Storage inside an IRA runs in two allocated subtypes. Segregated returns your specific PAMP bar at distribution, matched by serial number. Commingled returns equivalent PAMP bars of the same size and fineness. Both are compliant under section 408(m)(3), and segregated typically costs more per year. See allocated vs unallocated metals and segregated vs commingled storage for the trade-offs.
Traps that can knock the bar out of eligibility
A PAMP Suisse platinum bar is IRA-eligible on its own, but several ways of handling the order can still push the account into a taxable event. Watch for each one on your intake call.
- Buying the bar in your own name, then trying to "contribute" it. An in-kind contribution of a bar you already own is not how the statute works. The IRA cash pays the dealer directly. If you already hold a PAMP bar in your personal safe, that bar cannot move into the IRA later.
- Taking delivery of the bar at home first. Even a short detour through personal possession voids the trustee-possession rule under 408(m). Ship-to on the invoice must be the depository, not your home or your dealer's holding area.
- Substituting a "PAMP-equivalent" bar at delivery. The custodian settles against the exact refiner and size on the purchase confirmation. If the dealer swaps in a different refiner because the PAMP stock ran short, the confirmation has to be reissued and signed again before settlement.
- Numismatic or "collector" upsells. PAMP produces themed and decorative platinum products alongside investment bars. A themed collector item outside the plain .9995 investment line raises collectibles questions under 408(m). Stick to the standard investment bar line for an IRA order.
- A dealer that will not name the depository. A refusal to state the ship-to depository in writing is a sign the order flow does not match the IRA compliance chain. Every compliant order names the vault before the wire.

Questions savers ask about PAMP platinum
Are PAMP Suisse platinum bars IRA-eligible?
Yes. PAMP Suisse platinum bars are refined at .9995 fine and pass the fineness test in IRC section 408(m)(3)(B). PAMP is on the London Platinum and Palladium Market Good Delivery list, and the refiner is accepted by the depositories most self-directed IRA custodians settle to. The metal still has to reach an IRS-approved depository directly to satisfy the trustee-possession rule.
What sizes of PAMP platinum bars can I hold in an IRA?
All standard PAMP investment sizes qualify at the same .9995 fineness. Sizes include 1 g, 5 g, 10 g, 20 g, 1 troy oz, 50 g, 100 g, 10 troy oz, and 1 kg. The 1 troy ounce bar is the most common ticket size for a retirement account because it balances premium per ounce against divisibility at future sale.
Does the CertiPAMP assay card matter for an IRA?
The CertiPAMP card on minted bars carries the serial number and assay of the specific bar, in a tamper-evident sleeve. The depository logs that serial when the bar arrives. Keeping the bar in the sealed card protects resale value later. Cast bars carry the serial and refiner stamp on the bar and ship with a separate paper assay certificate.
Is a PAMP platinum bar cheaper than a Platinum American Eagle?
Usually yes on premium per ounce, though the gap moves day to day. Sovereign coins carry mint premiums that bars do not. Coins carry higher volume and can offer a tighter buy-back spread at sale time. A dealer should quote both premium and same-day buy-back on the specific product before you commit.
Do custodians accept PAMP platinum bars across the board?
Most self-directed IRA custodians that handle physical metals accept PAMP Suisse platinum bars because the refiner sits on the LPPM Good Delivery list. Individual custodians can still restrict specific sizes or formats for operational reasons. Ask the custodian in writing which PAMP sizes it settles before placing the order.
Can I store a PAMP platinum bar at home if it is inside my IRA?
No. IRC section 408(m) requires an IRS-approved trustee to hold physical possession. Home storage of IRA metal fails that test. The Tax Court applied the same rule against the taxpayers in McNulty v. Commissioner, 157 T.C. 10 (2021). A home-stored bar can trigger a deemed distribution taxed at fair market value, plus the 10 percent early-withdrawal additional tax below age 59.5.
How does a PAMP bar compare with an Argor-Heraeus or Valcambi bar?
All three refiners are Swiss, all three appear on the London Platinum and Palladium Market Good Delivery list, and all three produce platinum at .9995 fine. A custodian will accept bars from any of the three for a fineness-route IRA order. Premium and availability shift by dealer and by day, so compare the specific size in writing before committing.
Can I combine PAMP bars with a Platinum American Eagle in the same IRA?
Yes. A single self-directed IRA can hold multiple eligible platinum products across both statutory routes. Some savers hold the 1 oz PAMP bar for tighter premium and a small stake in Platinum American Eagles for the coin premium. The custodian and depository track each item separately by serial number or by coin lot.
