400 oz Gold Bars

The 400 oz gold bar is a large-format bullion standard used in higher-value physical gold transactions, vault placement structures, and selected delivery routes.

This format carries a different execution profile than 1 kg bars because allocation, storage, transport, and transaction structuring are more closely tied to wholesale bullion practice and LBMA-linked bar categories.

Frequently asked questions

What is a 400 oz gold bar?
A 400 oz gold bar is a large-format bullion bar used in higher-value physical gold transactions. This format is commonly associated with wholesale bullion practice, vault-based execution, and larger-value allocation structures.
Yes. The 400 oz format is commonly used where transaction size, bar efficiency, and vault-based handling are central to the execution structure. It is typically requested in professional or larger-value transaction settings rather than smaller-format purchase scenarios.
A 400 oz bar carries substantially higher bullion value per bar and is more closely tied to wholesale bullion handling, vault placement, and larger-value execution routes. A 1 kg bar is more flexible as a transaction format and is commonly used across a wider range of purchase sizes.
The 400 oz format is commonly associated with LBMA-linked wholesale bullion categories. Final classification depends on the manufacturer, refinery-origin reference, and the bar specifications confirmed for the transaction.
Pricing is fixed by reference to the prevailing spot gold price together with the applicable product format, requested quantity, and execution terms. Final commercial confirmation reflects the selected bar, transaction structure, and agreed premium basis.

The documentation set may include commercial confirmation, payment confirmation reference, allocation record, product-identification details, and ownership-related transaction records. Where vault placement is selected, operator records may also include written receipts and deposit or withdrawal confirmations with account balances.
Yes. Following allocation, a 400 oz bar may remain in third-party vault placement where that route is selected for the transaction. Storage jurisdiction, operator route, and supporting records form part of the execution structure.
Yes. A 400 oz bar may be released for physical delivery under documented delivery instructions and the selected execution route. Delivery proceeds after transaction approval, payment confirmation, and the applicable release and transport coordination steps.
The transaction evidence set may include commercial confirmation, payment confirmation reference, allocation reference, transaction identifier, and delivery or storage records where applicable. Bar-level identifiers may also support the allocation record where relevant.
Execution is available to qualified investors and corporate counterparties subject to onboarding and transaction approval. Approval includes risk-based AML/KYC review, screening, and payment-route verification before the transaction proceeds.
Minimum transaction scope depends on the requested format, execution route, and commercial structure confirmed for the transaction. Final parameters are established during commercial review and onboarding.
