When you buy gold — whether it’s a bar, a coin, or any other form — one of the most important things you can check is where that gold came from. Specifically, who refined it? The answer matters more than most new buyers realize. The London Bullion Market Association, known as the LBMA, maintains a list of approved gold refiners whose products meet strict global standards. Understanding what that list means, and why it should influence your buying decisions, is one of the smartest first steps you can take as a precious metals investor.
What Is the LBMA?
The London Bullion Market Association is an international trade association that represents the global over-the-counter market for gold and silver. It sets the benchmark standards that banks, central banks, and institutional traders use when they buy and sell bullion. While it is based in London, its influence reaches every corner of the global gold market — including the United States.
The LBMA publishes what it calls the Good Delivery List. This is a roster of refiners whose gold bars have been tested and certified to meet strict criteria for purity, weight, dimensions, and quality. A gold bar produced by an LBMA-accredited refiner is widely accepted by banks, vaults, and exchanges around the world without question. That acceptance is the core of what makes LBMA accreditation valuable.
Getting on the Good Delivery List is not easy. Refiners must pass a rigorous proactive monitoring program. They submit bar samples for independent chemical testing, and they must demonstrate consistent production quality over time. The LBMA also evaluates a refiner’s compliance with responsible sourcing standards, which we’ll discuss further below.
What Does LBMA Accreditation Actually Require?
For gold, an LBMA Good Delivery bar must meet specific technical standards. The gold content must be at least 995 parts per thousand fine — in other words, at least 99.5% pure gold. The bar must weigh between roughly 350 and 430 troy ounces, which is the standard large bar format used in institutional trading. Each bar must also carry specific markings: the serial number, the assay stamp, the year of manufacture, and the refiner’s hallmark.
These requirements ensure uniformity. When a central bank in Tokyo sells gold to a dealer in London, both parties know exactly what they are getting. That predictability reduces risk and eliminates the need for repeated assaying at every point of transfer. It is the foundation of a liquid, trustworthy global market.
Beyond the physical standards, the LBMA also requires accredited refiners to comply with its Responsible Gold Guidance. This means refiners must have systems in place to prevent the processing of gold linked to conflict, human rights abuses, or money laundering. They must conduct due diligence on their supply chain and report on their practices. This responsible sourcing component has become increasingly important to institutional buyers and ethical investors alike.
Why Does This Matter to Individual Investors?
You might be thinking: I’m not a central bank. I’m buying a one-ounce gold bar or a few coins. Why does the LBMA list matter to me? The answer comes down to resale value and liquidity. When you eventually want to sell your gold, a buyer — whether it is a dealer, a refiner, or another private party — will look at where your gold came from. Gold produced by LBMA-accredited refiners is recognized and accepted globally with minimal friction.
Gold bars or coins from unknown or unaccredited sources may require additional assaying before a dealer will accept them. Some dealers will simply discount them or refuse them entirely. That discount comes directly out of your pocket. Buying from recognized, accredited refiners protects the resale value of your holdings from day one.
It also protects you against counterfeits. LBMA-accredited refiners use sophisticated anti-counterfeiting measures, and their products are well documented. Fakes are far more likely to be passed off as bars from obscure or unverifiable sources. Sticking to LBMA-recognized products is one of the most practical ways to protect yourself as a buyer.
Well-Known LBMA-Accredited Refiners
The Good Delivery List includes refiners from across the world. Some names you will encounter frequently in the retail precious metals market include PAMP Suisse, Valcambi, Argor-Heraeus, and Perth Mint (for gold), as well as the Royal Canadian Mint and several major refiners based in the United States. These names appear on bars and coins sold through reputable dealers and are instantly recognizable to buyers worldwide.
Each of these refiners marks their products clearly. When you hold a PAMP Suisse bar or a Valcambi bar, you will see the refiner’s hallmark, the purity stamp, and the serial number right on the bar. Many also come with an assay card or certificate that verifies the specific bar’s weight and purity. That documentation is worth keeping.
It is worth noting that coins minted by government mints — such as the American Gold Eagle, the Canadian Gold Maple Leaf, or the South African Krugerrand — carry their own sovereign guarantee of purity and weight. While these coins may not always carry a traditional LBMA refiner hallmark, they are universally accepted because the governments behind them provide the same level of assurance that LBMA accreditation provides for bars.
How to Use This Information When You Buy
Before purchasing any gold product, it is worth taking a few simple steps to verify its origin and quality:
- Check the refiner’s name. Look up whether the refiner appears on the LBMA Good Delivery List, which is publicly available on the LBMA’s official website.
- Look for proper markings. A legitimate bar should display the refiner’s stamp, a purity marking, a serial number, and the year of manufacture.
- Ask for an assay card. Many reputable bars come packaged in an assay card or sealed blister pack that certifies the bar’s specifications.
- Buy from a reputable dealer. A trusted dealer will only carry products from recognized refiners and will stand behind what they sell.
- Verify with the manufacturer. Some refiners offer online serial number verification tools so you can confirm your specific bar is authentic.

Responsible Sourcing and Why It Is Growing in Importance
The LBMA’s responsible sourcing standards reflect a broader shift in how institutional buyers and individual investors think about gold. Conflict gold — gold mined in war zones and used to finance armed groups — has been a real problem in parts of Africa and other regions. By requiring refiners to trace and verify their supply chains, the LBMA helps ensure that the gold reaching the market has not funded violence or exploitation.
For investors who care about the ethical dimensions of their purchases, buying from LBMA-accredited refiners provides meaningful assurance. It is not a guarantee that every gram of gold in a bar was extracted under perfect conditions, but it is a credible, audited system designed to minimize the risk of conflict gold entering the global market.
Understanding the LBMA Good Delivery List gives you a real advantage as a gold buyer. It helps you choose products that are recognized worldwide, easier to resell, and backed by rigorous quality standards. Whether you are buying your first ounce or adding to an existing portfolio, sticking to products from accredited refiners and reputable government mints is one of the most straightforward ways to protect your investment.
