LBMA Good Delivery is the credentialing framework that decides which gold bars a U.S. self-directed IRA can legally hold. The statute that governs the IRA carve-out for bullion bars points at it by reference, not by brand name.

IRC §408(m)(3)(A) requires a minimum .995 fineness and a refiner accredited by the London Bullion Market Association or approved by a recognized commodity exchange. Every gold bar that clears an IRS-approved depository for an IRA account flows through one of those two credentials.

The refiner short list is far smaller than the brand catalog the retail market sees. Roughly seventy refiners worldwide carry LBMA Good Delivery status for gold. A handful of those refiners produce the bars that account for the overwhelming majority of IRA-routed orders in 2026. The same handful sets the per-ounce premium floor that every honest dealer quote starts from.

This article explains what LBMA Good Delivery actually means and enumerates the refiners whose bars routinely clear U.S. depository intake. It walks the size catalog from 1 oz through 1 kilo retail, with the 400 oz institutional bar held for context. It also maps the premium gradient by refiner and size, and lists the five errors that erode value on an LBMA bar order inside an IRA.

For a first-time IRA buyer about to authorize a bar order, the dealer running the wire matters more than the LBMA stamp on the bar. See the 2026 OPRS dealer verdicts for the BBB record and complaint history behind each clear-or-warn decision before any LBMA bar order is wired.

What LBMA Good Delivery actually certifies

LBMA Good Delivery is a refiner accreditation administered by the London Bullion Market Association. The accreditation covers both the refiner’s technical capacity (assay precision, melt-and-cast tolerance, weight accuracy) and the financial capacity to produce institutional-grade bars at scale. The signature product on the institutional side is the Good Delivery 400 oz bar, the bar that London settles its physical gold trades against and that central banks hold on vault account.

The accreditation has three operational tests for a refiner. First, an annual minimum output of melted gold bars (around 10 metric tonnes of gold, or roughly $750 million worth at typical 2026 prices). Second, a pass on the LBMA’s Pro-Active Monitoring sample assay, where an independent referee refiner verifies the candidate’s metal at the certified fineness. Third, ongoing compliance with the LBMA Responsible Gold Guidance, which mirrors the OECD Due Diligence framework for conflict-affected and high-risk areas.

Refiners that hold the accreditation can sell directly into the London wholesale market and produce smaller retail bars (1 g up through 1 kilo) that inherit the same refiner credential. A 1 oz PAMP Suisse bar shares the refiner certification of the same producer’s 400 oz Good Delivery bar; the IRS does not distinguish between the two from a credentialing standpoint under IRS Publication 590-A.

Referee refiners are a smaller subset of the Good Delivery list. Referees are the refiners the LBMA itself uses to verify other refiners’ samples. PAMP Suisse has held referee status since 1987. The full referee list is short (five refiners as of 2026) and carries a small but real liquidity premium at resale because the referee credential signals an additional layer of process trust.

The two prong eligibility test for IRA gold bars

The statute reaches gold bars through two paired tests that must both be met. Failing either prong disqualifies the bar from an IRA.

Fineness floor of .995. Gold bars from LBMA-accredited refiners typically come at .9999 fineness (the four-nines convention), which is well above the floor. The fineness test is the easier of the two prongs and very rarely the failure point on a bar from a serious refiner.
Refiner credential. The refiner must hold LBMA Good Delivery accreditation, or be approved on a recognized commodity exchange delivery list (COMEX, TOCOM, or NYMEX). Most LBMA Good Delivery refiners also hold COMEX approval, so the two credentials overlap. A privately minted bar at .9999 from an unaccredited refiner is collector property, not IRA property, regardless of the metal quality.

The credential test catches first-time IRA buyers who shop on price alone. A retail bar from a small private mint can cost less than a Good Delivery refiner’s bar at the same advertised fineness. The cheaper bar is not depository-eligible. An IRA owner who buys one for the IRA account discovers the rejection at intake, when the depository ships it back to the dealer and the trade has to be unwound.

The LBMA refiners whose gold bars routinely clear U.S. IRA depositories

The Good Delivery list runs to roughly seventy refiners worldwide, but the working set of refiners whose bars regularly arrive at Delaware Depository, IDS of Delaware, Brink’s Salt Lake City, and the other custodian-recognized vaults is shorter. Eight refiners account for the bulk of IRA-routed gold bars in 2026.

Three patterns are worth noting in this enumeration. First, Swiss refiners (PAMP, Valcambi, Argor-Heraeus) dominate the retail end of the LBMA list for bars commonly seen in U.S. IRAs. Switzerland houses the highest concentration of LBMA referee refiners.

Second, two North American refiners (Royal Canadian Mint and Asahi Refining) are present. That matters for IRA buyers who prefer a domestically or near-shore-produced bar for chain-of-custody comfort. Third, the Credit Suisse brand is legacy only as of the 2023 UBS-Credit Suisse merger. Pre-merger Credit Suisse bars remain fully IRA-eligible if intact in original packaging, but no new production carries the brand stamp.

Sizes commonly ordered under LBMA Good Delivery

LBMA-accredited refiners produce gold bars across a wide weight range. The institutional Good Delivery 400 oz bar is the bar London settles wholesale trades against and that central banks hold; it is not used in U.S. retail IRAs. The retail sizes that account for the bulk of IRA-routed orders cluster around four weights, all at .9999 fineness.

1 oz (31.103 grams). The most common retail size in U.S. IRAs. Highest divisibility at eventual liquidation, highest per-ounce premium relative to larger bars. Available in both cast and minted formats from PAMP, Valcambi, Argor-Heraeus, and others. Typical 2026 premiums are 4 to 7 percent over the LBMA AM gold fix.
10 oz (311.03 grams). A common mid-size for IRA buyers who want a balance between divisibility and lower per-ounce cost. Typical 2026 premiums are 3 to 5 percent over spot.
1 kilo (32.151 oz, 1,000 grams). The retail-IRA cost leader on a per-ounce basis. Used for IRA allocations large enough to absorb the loss of divisibility at liquidation (most retirees hold long, so the divisibility loss rarely matters). Typical 2026 premiums are 2 to 4 percent over spot.
100 g (3.2151 oz). A mid-tier bar size common in European and Asian markets, less common in U.S. IRAs because the 1 oz and 10 oz dominate the size choice. When ordered, typical 2026 premiums are 4 to 6 percent over spot.

The 400 oz Good Delivery bar sits at the institutional end of the catalog. A single 400 oz bar holds gold worth roughly $1 million at typical 2026 prices, far above what a retail IRA buyer would order in one piece. The 400 oz bar is rarely vaulted into a self-directed IRA. Custodians that allow it require the IRA to fund the bar plus a refining fee if the bar later needs to be broken down for distribution.

The premium gradient across LBMA refiners at the 1 oz size

Within the eight refiners enumerated above, premium pricing varies by brand recognition, format (cast versus minted), and dealer positioning. The variation is modest but real, and it compounds across a five-figure IRA-funding order. The FINRA Investor Alert on precious metals documents the dealer-markup variability that produces this gradient. Industry-reported midpoints over the LBMA AM gold fix for cast 1 oz bars in 2026 cluster around the following ranges by refiner.

Horizontal bar chart of industry-reported dealer premium midpoints over the LBMA AM gold fix for 1 oz cast gold bars in 2026 across eight LBMA Good Delivery accredited refiners. PAMP Suisse at approximately five percent, Valcambi Suisse at approximately five percent, Royal Canadian Mint at approximately four and a half percent, Perth Mint at approximately five point five percent, Heraeus at approximately four point five percent, Argor Heraeus at approximately five percent, Credit Suisse legacy at approximately six percent, and Asahi Refining at approximately four percent. The variation across LBMA accredited refiners at the one ounce cast bar size sits within roughly three percentage points of band, with Asahi Refining at the low end and Credit Suisse legacy at the high end reflecting scarcity premium on out of production stock. — Figure 1. Industry-reported dealer premium midpoints over the LBMA AM gold fix on 1 oz cast gold bars from the eight LBMA Good Delivery accredited refiners that account for the bulk of IRA-routed orders in 2026. The band runs about three percentage points wide across the working set. Sources: FINRA Investor Alert on precious metals; major U.S. self-directed dealer published rate sheets for 1 oz cast bar product; LBMA Good Delivery refiner roster.

The premium gradient compresses at the 10 oz and 1 kilo sizes because the per-bar refining and assay overhead becomes a smaller fraction of total cost. At the 1 kilo bar size, premiums across the eight refiners typically cluster within a 1 percentage point band.

At the 1 oz size, the band is closer to 3 percentage points. For an IRA buyer placing a five-figure order, the brand choice at the 1 oz size affects total acquisition cost by a measurable but not enormous amount.

The minted-versus-cast format choice adds another 1 to 3 percentage points to the bar’s premium across all refiners. Minted bars (the PAMP Lady Fortuna line, Argor-Heraeus Kinegram-secured bars, and others) carry additional fabrication cost relative to plain cast bars. The trade-off is slightly tighter dealer buy-back spreads at eventual liquidation because the design features improve counterfeit resistance.

Acquisition flow for LBMA bars into a self-directed IRA

An IRA owner cannot take physical possession of LBMA bars owned inside the IRA. Direct possession triggers a deemed distribution under IRC §408(m). The full metal value is taxed as ordinary income in the year of receipt. If the owner is under age 59 1/2, a 10 percent early-distribution penalty applies. The bars must flow from the dealer directly to an IRS-approved depository titled in the name of the self-directed IRA custodian.

Five step procedural flowchart for acquiring an LBMA Good Delivery accredited gold bar inside a self-directed IRA. Step 1 open a self-directed IRA with a custodian authorized to hold precious metals under IRC Section 408. Step 2 fund the account via a direct trustee to trustee transfer or a 60 day indirect rollover from an existing IRA or employer plan. Step 3 issue a direct purchase order to the dealer specifying an LBMA accredited refiner, bar size, cast or minted format, and quantity at the LBMA AM fix or quoted spot plus stated premium. Step 4 the custodian wires settlement funds directly from the IRA cash position to the dealer under the trust title of the IRA, never to the account holder personally. Step 5 the dealer ships the bars in sealed original refiner packaging directly to the IRS approved depository which logs serial numbers and assigns segregated or commingled storage. — Figure 2. Five step procedural sequence for acquiring an LBMA Good Delivery accredited gold bar inside a self-directed IRA without triggering the IRC Section 4975 prohibited transaction rules. The bar must never touch the account holder’s possession; the chain runs custodian to dealer to depository, with original refiner packaging preserved end to end. Sources: IRC Section 408(m); IRC Section 4975; LBMA Good Delivery framework; IRS Publication 590-A.

The first step is opening the self-directed IRA. A standard brokerage IRA cannot hold physical metals. A self-directed custodian (Equity Trust, STRATA, Kingdom Trust, and others on the custodian-recognized list) is required. The second step is funding the account by rollover, transfer, or contribution. The third step is the purchase order itself, where the IRA owner directs the custodian to acquire a specific refiner, bar size, and format at the day’s price.

The fourth step is the cash wire. The custodian wires settlement funds to the dealer under the trust title of the IRA, never to the account holder personally. The custodian then instructs the dealer to ship the bars directly to the IRA’s depository of record.

The fifth step is depository intake. The depository receives the bars in their original sealed packaging, verifies serial numbers and weight against the dealer’s manifest, and books the bars into the IRA’s account under either segregated or commingled storage.

Dealer selection at the third step is where the IRA buyer’s largest variable cost concentrates. The dealer’s markup over spot, the spread on buy-backs, the complaint history with state attorneys general, and the CFTC enforcement record all attach to the trade. Check the chosen dealer against the 2026 OPRS verdicts before authorizing the custodian to wire payment. The operators that concentrate state-AG and CFTC enforcement actions also concentrate the wide-markup behavior that an LBMA refiner’s published premium range frames against.

Storage at the depository: segregated versus commingled for LBMA bars

IRS-approved depositories hold IRA metals under one of two arrangements. Segregated storage places the specific bars purchased for the account in a separately-tagged compartment under the IRA’s name, with the bar serial numbers logged to the account. Commingled storage pools the bars with other clients’ bars of the same specification, and the IRA holds a claim on an equivalent weight at the same refiner and fineness.

For LBMA bars, segregated storage is more common than for fungible bullion coins. The bar’s serial number is the trace identifier. A specific PAMP, Valcambi, or Royal Canadian Mint kilo bar bearing a recorded serial number is the asset on the account. A commingled-storage swap-out at distribution would deliver a different LBMA bar of the same refiner, weight, and fineness, which is functionally equivalent but loses the original serial-number trace.

Industry-reported segregated storage fees for LBMA bars typically run 0.5 to 1.0 percent of asset value per year, or a flat $150 to $250 on smaller accounts. Commingled fees typically sit 25 to 40 percent lower. The serial-number preference is set at the time of order and rarely changes during the account’s life.

Five mistakes that erode value on an LBMA bar IRA order

Buying a bar from an unaccredited refiner because the price was lower. A privately-minted bar at advertised .9999 from a refiner not on the LBMA Good Delivery list (and not approved on a recognized commodity exchange) is not depository-eligible. The bar will be rejected at intake. Correction: confirm the refiner against the published LBMA Good Delivery list before authorizing the order. The eight refiners enumerated above cover the working set.
Ordering sub-ounce bars (1 g to 10 g) for a retirement-allocation order. The per-ounce premium on gram bars routinely runs 8 to 18 percent over spot, versus 2 to 4 percent on a kilo. For an IRA holding gold as a long-term position, the gold content is what matters, not the divisibility. Correction: order the largest LBMA bar size that fits the funding amount. A $30,000 order is one 10 oz bar plus a top-up; a $60,000 order is one 1 kilo bar.
Asking the dealer to ship bars to the IRA owner’s home first. Any physical receipt by the IRA owner is a deemed distribution under IRC §408(m), with full ordinary-income tax on the value plus a 10 percent penalty under age 59 1/2. Correction: the custodian directs the dealer to ship directly to the IRA’s depository of record. The IRA owner never touches the bars.
Removing the refiner’s assay card or seal before depository receipt. Depositories reject LBMA bars that arrive outside the refiner’s original sealed packaging (CertiPAMP card for PAMP, sealed envelope for Valcambi, plastic sleeve for RCM and others). The seal is the verification chain that protects the IRA against substitution disputes at eventual liquidation. Correction: confirm with the dealer at order time that the bars ship sealed in original refiner packaging, never opened.
Paying a “rare bar” or “collector edition” premium for a retirement account. LBMA-accredited refiners do not strike numismatic gold. The Lady Fortuna, Kinegram, and other minted lines are bullion products with a small minted-bar premium, not collectibles with appreciation potential. Correction: pay no more than the published industry-reported premium band for the size and format ordered. See the 2026 OPRS dealer list for the operators that concentrate the rare-bar sales pattern.

Do all LBMA Good Delivery refiners produce IRA-eligible bars?

In principle, yes. Any refiner on the LBMA Good Delivery list satisfies the refiner credential prong of IRC §408(m)(3)(A). In practice, U.S. self-directed IRA depositories maintain their own accepted-refiner lists that overlap with but do not perfectly match the full LBMA list.

A small refiner whose bars rarely appear in U.S. supply may not be on every depository’s intake list, even though the bar satisfies the statute. The eight refiners enumerated in this article cover virtually every U.S. depository’s accepted list.

A bar from a less common LBMA-accredited refiner can still be IRA-eligible; the buyer should confirm with the IRA’s custodian and depository before placing the order. Confirmation typically takes a phone call to the depository compliance desk and an emailed bar specification sheet. The dealer placing the order should be able to facilitate that confirmation.

How does the LBMA framework differ from COMEX-approved refiners?

IRC §408(m)(3)(A) accepts either an LBMA-accredited refiner or a refiner approved on a recognized commodity exchange. The COMEX gold contract published by CME Group maintains its own approved-refiner list for physical delivery against the contract. The overlap between the LBMA Good Delivery list and the COMEX-approved list is large but not perfect.

Most major refiners (PAMP, Valcambi, RCM, Perth, Heraeus, Argor-Heraeus) hold both credentials. A bar from a refiner approved on COMEX but not on the LBMA list still satisfies the statute. A bar from a refiner on the LBMA list but not on COMEX also satisfies the statute. The IRS does not require both.

The practical implication for an IRA buyer is that the refiner credential test is broader than just LBMA. The SEC investor education page on precious metals reflects this dual-credential reality in its general guidance on bullion eligibility.

For a first-time IRA buyer about to authorize an LBMA bar order, four elements need to be settled before the custodian’s settlement wire.

The refiner choice from the working LBMA Good Delivery short list. PAMP, Valcambi, RCM, Perth, Heraeus, Argor-Heraeus, and Asahi Refining cover virtually every U.S. depository’s intake list.
The bar size mix. Default to the largest LBMA bar that fits the funding amount, with smaller bars added only if a specific reason exists.
The cast-versus-minted format decision. Cast for cost efficiency; minted for slightly tighter resale spreads.
The dealer’s BBB record, complaint history with state attorneys general, and CFTC enforcement history.
