How to Verify LBMA Compliance When Sourcing Silver Bars from Hong Kong
Published: 2026-07-29
Category: How-To Guide / Tutorial
Sourcing high-purity silver bars from Hong Kong offers industrial buyers access to one of the world’s most liquid precious metals markets. However, with the rise of counterfeit and non-compliant product, verifying LBMA Good Delivery status has become a critical step for any serious buyer. This guide provides a clear, actionable process for confirming that your silver bars meet the London Bullion Market Association (LBMA) standards — from checking refiner accreditation to validating assay certificates.
Whether you are a manufacturer in the United States, a trader in Japan, or a wholesaler evaluating suppliers, these steps will help you avoid costly mistakes and ensure your supply chain is built on verified quality.
Why LBMA Compliance Matters for Industrial Silver Buyers
LBMA compliance is the global benchmark for silver bar quality and integrity. Bars that meet the Good Delivery standard are guaranteed to be at least 99.99% pure silver, produced by accredited refiners, and backed by a strict chain of custody. For industrial buyers, this means:
- Assured purity for manufacturing processes (electronics, photovoltaics, medical devices).
- Ease of trade — LBMA bars are accepted by major exchanges and refiners worldwide.
- Lower counterparty risk when dealing with Hong Kong silver exporters.
- Compliance with international regulations for export to the US, Japan, and other markets.
Without LBMA verification, buyers risk receiving silver that is underweight, impure, or even fraudulent — a problem that has increased as global demand for premium silver trading in Hong Kong has grown.
Understanding the LBMA Good Delivery Standard for Silver
The LBMA Good Delivery List is the official register of refiners whose silver bars meet the association’s strict criteria. For silver, the standard requires:
- Minimum fineness of 999.0 parts per thousand (99.9% purity) — though most bars are 99.99%.
- Weight range of 500 to 1,250 troy ounces (approximately 15.5 kg to 38.9 kg).
- Specific dimensions, markings, and serialisation.
- Annual re-auditing by LBMA-approved inspectors.
Importantly, LBMA compliance is refiner-specific, not product-specific. A bar is only LBMA Good Delivery if it was produced by a refiner currently on the Good Delivery List. This distinction is crucial when sourcing from Hong Kong, where some traders may sell bars from non-accredited refiners.
Step 1: Check the Official LBMA Good Delivery List of Accredited Refiners
The first and most reliable step is to consult the LBMA’s official Good Delivery List. The LBMA publishes a current PDF on its website listing all accredited refiners for gold and silver. Here’s how to use it:
- Visit the LBMA website and navigate to the Good Delivery section.
- Download the latest Silver Good Delivery List (updated quarterly).
- Search for the refiner name that appears on the bar you intend to purchase.
- Confirm that the refiner’s status is “Current” — not “Suspended” or “Removed”.
Pro tip: Many Hong Kong silver exporters source from refiners based in mainland China, Australia, or Europe. Always verify the refiner’s name exactly as it appears on the LBMA list. Some fraudulent bars use names that are very similar to accredited refiners (e.g., “Metalor Technologies” vs. “Metalor Tech”).
Step 2: Verify Serial Numbers and Hallmarks on Silver Bars
Every LBMA Good Delivery silver bar is stamped with a unique serial number, the refiner’s hallmark, the year of manufacture, and the weight and fineness. When inspecting a bar — either in person or via high-resolution images from your supplier — check for:
- Refiner’s mark — a logo or abbreviation that matches the LBMA-accredited entity.
- Serial number — should be clearly engraved and not appear tampered with.
- Weight and fineness — e.g., “1000 oz 999.9”.
- Year of production — usually a two- or four-digit year.
If you are buying 99.99% silver bars for sale from a Hong Kong exporter, ask for a photograph of the bar’s markings. Cross-reference the serial number with the refiner’s database if possible. Some major refiners (e.g., Johnson Matthey, Metalor, PAMP) offer online verification tools.
Step 3: Request and Validate Supplier Documentation (Assay Certificates, SGS Reports)
Reputable Hong Kong silver exporters provide comprehensive documentation with every shipment. The key documents to request are:
| Document | What It Confirms | How to Validate |
|---|---|---|
| Assay Certificate | Purity (e.g., 99.99% silver) and weight of each bar or lot. | Check that the certificate is issued by an LBMA-accredited assayer or a recognised laboratory (e.g., SGS, Inspectorate). |
| SGS Report | Independent third-party verification of weight, dimensions, and purity. | Verify the report number with SGS directly. Ensure the seal and signature are authentic. |
| Certificate of Origin | Country where the silver was refined. | Cross-reference with the refiner’s location on the LBMA list. |
| Commercial Invoice | Description of goods, including LBMA compliance statement. | Ensure the invoice explicitly states “LBMA Good Delivery” or “LBMA Compliant”. |
Important: Some exporters may provide a “certificate of analysis” from their own lab. While useful, this is not a substitute for an independent assay. Always request an SGS or equivalent third-party report, especially for large wholesale orders.
Step 4: Confirm the Chain of Custody from Refinery to Export
LBMA compliance extends beyond the bar itself — it also requires a transparent chain of custody. When sourcing from a Hong Kong silver exporter, ask for:
- Refinery dispatch notes showing the bar numbers and destination.
- Shipping documents (airway bill or bill of lading) that match the bar numbers.
- Insurance certificates covering the shipment.
- Customs declarations for export from Hong Kong.
For buyers in the US or Japan, a clear chain of custody also helps with import clearance. Customs authorities may request proof that the silver originated from an LBMA-accredited refiner. If the chain is broken, your shipment could be delayed or subject to additional duties.
Common Red Flags and How to Avoid Non-Compliant Silver
Even experienced buyers can be misled. Watch for these warning signs when evaluating a Hong Kong silver exporter:
- Refiner not on the LBMA list — the most obvious red flag. If the refiner is not accredited, the bar is not LBMA compliant, regardless of what the seller claims.
- Missing or illegible hallmarks — bars with worn or altered markings may be counterfeit.
- Unusually low premiums — if a deal seems too good to be true, it probably is. LBMA bars command a premium over spot price.
- Reluctance to provide documentation — a reputable exporter will share assay certificates and SGS reports without hesitation.
- Pressure to pay via untraceable methods — always use bank transfers or escrow services for large transactions.
To protect yourself, always request a pre-shipment inspection by an independent third party. Many Hong Kong exporters allow inspection by SGS or similar agencies before payment is released.

Frequently Asked Questions
What does LBMA compliant mean for silver bars?
LBMA compliant means the silver bar meets the London Bullion Market Association’s Good Delivery standard: minimum 99.9% purity, produced by an LBMA-accredited refiner, and properly marked with a serial number and hallmark.
How can I check if a Hong Kong silver exporter is reliable?
Start by verifying their refiner sources against the LBMA Good Delivery List. Request independent assay reports (e.g., SGS), check for transparent documentation, and ask for client references. A reliable exporter will also provide full chain-of-custody records.
Is LBMA compliance the same for silver bars sold in Asia vs London?
Yes — the LBMA Good Delivery standard is global. A bar that is LBMA compliant in Hong Kong is also compliant in London, New York, or Tokyo. However, some Asian markets also accept bars from non-LBMA refiners, so always confirm the standard before purchasing.
What is the current premium on silver bars in Hong Kong?
Premiums vary based on bar size, purity, and market conditions. For LBMA Good Delivery bars (1000 oz), premiums typically range from $0.10 to $0.50 per ounce over the spot price. Smaller bars (100 oz) may carry higher premiums. Check live prices on exchanges like the Hong Kong Mercantile Exchange or LBMA for current rates.
Can I buy LBMA silver bars from Hong Kong for delivery to the US?
Yes. Many Hong Kong exporters, including HK Changjiang, ship LBMA-compliant silver bars directly to the United States. Ensure the exporter handles customs documentation and uses insured shipping. Import duties on silver bullion into the US are generally 0% for investment-grade bars.
How do I verify a silver bar’s serial number?
Contact the refiner directly or use their online verification tool (if available). For bars from major refiners like Metalor, PAMP, or Johnson Matthey, you can often check the serial number on their website. For other refiners, request a letter of authenticity from the supplier.
