LBMA Good Delivery: The Global Gold Standard for Bar Quality

The London Bullion Market Association (LBMA) Good Delivery standard is the most important quality benchmark in the global gold market. A 400-troy-ounce bar that meets LBMA Good Delivery specifications can be traded in the London OTC market — the world's largest and most liquid gold trading venue, processing roughly $18 trillion in turnover annually. Understanding what Good Delivery means, why it matters, and how it connects to the gold bars available in IRA accounts helps investors evaluate the quality and provenance of the gold they hold.

The Good Delivery Specifications

LBMA Good Delivery gold bars must meet precise specifications. The weight must be between 350 and 430 troy ounces (the standard is 400 troy ounces, approximately 27.4 pounds). The fineness (purity) must be a minimum of .995 (99.5% pure gold), though most modern refinery bars are .9999 (.999.9). Each bar must carry the refiner's stamp, a serial number, the year of manufacture, and the fineness. The bar's surface must be smooth, free of shrinkage cavities, and suitable for counting and stacking in vault conditions.

The bars are assayed and tested against these specifications by the accredited refiner. The LBMA maintains a Good Delivery List of approved refiners — currently approximately 75 refiners worldwide — and periodically conducts proactive monitoring to ensure continued compliance. Bars from non-listed refiners are not acceptable in the London market without additional testing.

The Good Delivery List

Accreditation to the LBMA Good Delivery List requires refiners to meet strict criteria: demonstrated financial viability, technical capability, documented quality management systems, and successful testing of sample bars. The list includes the major Swiss refiners (Valcambi, PAMP, Argor-Heraeus), major national refineries (Royal Canadian Mint, Perth Mint, U.S. Assay Office products), and large industrial refiners from South Africa, China, Russia, and elsewhere.

Good Delivery accreditation is not permanent — the LBMA reviews listed refiners and has suspended or delisted refiners for quality or compliance issues. The Russian refiner issue post-2022 sanctions is the most prominent recent example: the LBMA suspended several Russian refiners from the Good Delivery List, meaning Russian-origin gold produced after March 2022 is not acceptable in the London market regardless of its technical purity.

Relevance for IRA Investors

IRA investors typically hold 1 oz, 10 oz, or 100 oz gold bars rather than 400 oz institutional bars. But the Good Delivery framework matters indirectly in two ways:

First, the SDIRA custodian's approved product lists generally correspond to products from LBMA Good Delivery-listed refiners or COMEX-approved assayers and refiners (the two lists largely overlap). Sticking to products from these refiners ensures maximum portability and acceptance across custodians, depositories, and dealers.

Second, when IRA gold is eventually liquidated — through in-kind distribution, sale, or estate transfer — bars from Good Delivery-accredited refiners sell at full market value without question. Non-accredited bars or those from obscure sources may require assaying (an additional cost and time delay) before a dealer will buy at full spot price.

The LBMA Good Delivery standard, while invisible to most retail investors, is the bedrock of international gold market integrity. For IRA investors, awareness of it translates into one simple rule: buy gold from refiners on the Good Delivery List, and every future transaction will be straightforward.
