LBMA Good Delivery

Definition

The London Bullion Market Association (LBMA) Good Delivery standard is the global benchmark for gold and silver bar quality, defining the weight, dimensions, fineness, and appearance requirements that bars must meet to be eligible for settlement in the London bullion market and, by extension, in most major global gold trading venues. A gold bar meeting Good Delivery specifications weighs between 350 and 430 troy ounces (approximately 10.9 to 13.4 kilograms), with a minimum fineness of 995 parts per thousand of pure gold. The standard is maintained by the LBMA through an accreditation process that qualifies refiners to produce bars bearing the Good Delivery mark.

In the UAE’s gold tokenization ecosystem, LBMA Good Delivery is the foundational quality standard. Both Tether Gold (XAUT) and Paxos Gold (PAXG) — the two largest gold tokens with combined market capitalization exceeding $5.3 billion — are backed exclusively by LBMA Good Delivery bars. The standard’s role in gold tokenization extends beyond quality assurance; it provides the verifiable, standardized unit of gold that makes credible 1:1 token backing possible.

Technical Specifications

LBMA Good Delivery bars must meet precise physical requirements:

Weight. Gold bars must weigh between 350 and 430 troy ounces. The exact weight is stamped on each bar and recorded on the bar’s assay certificate. This weight range, while standardized, means each bar is unique — a fact that carries implications for tokenization, since token-to-bar mapping must account for varying bar weights.

Fineness. Minimum fineness is 995.0 parts per thousand of pure gold. Most modern Good Delivery bars achieve 999.9 fineness (four nines fine), exceeding the minimum requirement. The fineness is stamped on the bar and confirmed through assay testing.

Dimensions. While exact dimensions vary by refiner and weight, bars are typically approximately 255mm x 81mm x 37mm. The bar must be rectangular with no cavities, have a flat base, and be suitable for secure stacking in vault storage.

Markings. Each Good Delivery bar must bear the refiner’s hallmark, the year of manufacture, a unique serial number, the fineness, and the weight in troy ounces. These markings provide the identity chain that connects physical bars to digital gold token records.

LBMA Accreditation

The LBMA maintains a Good Delivery List of accredited refiners that have demonstrated the capability to consistently produce bars meeting the standard. Accreditation involves:

Application and Assessment. Prospective refiners submit an application accompanied by sample bars for independent assay testing. The LBMA’s referees evaluate the bars against the Good Delivery specifications and assess the refiner’s quality control systems.

Proactive Monitoring. Accredited refiners are subject to ongoing monitoring, including unannounced sample testing and periodic inspections. Refiners that fail to maintain standards are suspended or removed from the Good Delivery List.

Responsible Gold Guidance. Since 2012, LBMA Good Delivery accreditation has included compliance with the LBMA Responsible Gold Guidance, which requires refiners to implement supply chain due diligence to prevent the processing of gold from conflict-affected areas, money laundering, or terrorist financing.

Several UAE-based refiners hold LBMA Good Delivery accreditation, including Emirates Gold and Al Etihad Gold Refinery, both operating within the DMCC free zone. This local refining capacity means that gold bars produced in Dubai can enter the Good Delivery ecosystem directly, without requiring international transport for accreditation testing.

Role in Gold Tokenization

LBMA Good Delivery provides the trust infrastructure that makes gold tokenization credible at institutional scale. The standard’s role in the tokenization chain includes:

Backing Verification. Token issuers like Tether and Paxos reference specific Good Delivery bars by serial number, refiner, and weight in their reserve attestations. This specificity allows auditors and token holders to verify that each token corresponds to identifiable physical gold meeting a recognized quality standard.

Redemption Mechanics. Token holders who redeem their tokens for physical gold receive Good Delivery bars (or, for smaller redemptions, smaller bars or coins sourced from the liquidation of Good Delivery inventory). The standardized bar format ensures redemption fungibility — a holder redeeming 400 troy ounces of XAUT receives a Good Delivery bar regardless of which specific bars originally backed their tokens.

Custody Standards. Vault operators custodying gold for tokenization programs must maintain LBMA Good Delivery segregation and inventory management practices. Bars allocated to token backing must be identifiable and auditable separately from unallocated or allocated-to-other-purposes gold held in the same vault.

Price Reference. The LBMA Gold Price, set twice daily through an electronic auction among accredited market makers, serves as the primary reference price for gold tokens. Token premiums and discounts are measured against this benchmark, and the gold token premium/discount analysis tracks these deviations across XAUT, PAXG, and other gold tokens.

UAE Gold Market Connection

The UAE’s gold market infrastructure — centered on DMCC, the Dubai Gold and Commodities Exchange (DGCX), and the physical gold souk — operates within the LBMA ecosystem. DMCC’s role as a global hub for gold trading and refining means that significant quantities of Good Delivery bars are produced, stored, and traded within the UAE.

This physical proximity creates opportunities for UAE-based gold tokenization programs to reduce the geographic distance between the physical gold backing and the token issuer’s operations. While current market leaders (XAUT and PAXG) custody their gold in Switzerland and London respectively, the UAE gold trade tokenization gap analysis examines the potential for UAE-vaulted, UAE-regulated gold token programs.

The physical gold vs tokenized gold comparison examines how LBMA Good Delivery bars traded through traditional channels differ from tokenized representations of the same underlying gold.

Islamic Finance Considerations

Under AAOIFI Shariah Standard No. 57 on gold, the quality and provenance of the underlying gold affects its permissibility in Islamic finance transactions. LBMA Good Delivery’s responsible sourcing requirements and quality standards provide a baseline of assurance that is relevant to Shariah governance boards evaluating gold-backed tokens for compliance with Islamic commercial law principles.

The Islamic Finance Portal references AAOIFI’s gold standard in the context of gold-based banking and finance products, which extends to tokenized gold instruments.
