Where can I download the CME Group 'service providers' XLS that lists COMEX Silver (SI) brands?
Executive summary
The COMEX “service providers” spreadsheet—an XLS that includes a “Silver (SI) Brands” tab listing eligible COMEX silver brands—is published directly on CME Group’s website and can be downloaded from the service-providers.xls URL on the CME rulebook/files area [1]. CME’s recent market notice also explicitly points traders to the “Silver (SI) Brands” tab in that service providers table at the end of Chapter 7 of the COMEX Rulebook [2].
1. Where to download the XLS: the direct CME link
The primary, publicly accessible download for the COMEX service providers spreadsheet is hosted by CME Group at the service-providers.xls address in their rulebook files directory; that file is the spreadsheet cited by market commentators and by CME itself as containing the “Silver (SI) Brands” tab [1]. For related delivery and stocks spreadsheets CME also publishes specific XLS files (for example, a Silver_stocks.xls delivery report hosted under CME’s delivery_reports path), but the brand list is in the service-providers.xls file noted above [3] [1].
2. What the file contains and where the Silver brands are located
CME’s market notice describing a change to silver brands makes clear the brands list is in the “Silver (SI) Brands” tab within the service providers table placed at the end of Chapter 7 of the COMEX Rulebook, and that the change was effective immediately upon the notice [2]. That same structure—the multi-tab spreadsheet with “Gold (GC) Brands” and “Silver (SI) Brands” tabs—has been referenced by third-party analysts who extract and report on the expanded lists from the spreadsheet itself [4], confirming that the XLS contains the brand-level eligibility data traders seek.
3. How CME references and updates the list (formal provenance)
CME’s market regulation notice explicitly links the brand-change language to the service providers table in the COMEX Rulebook and describes the regulatory notification process to the CFTC for brand changes, indicating the spreadsheet is the formal, exchange-published source for eligible delivery brands [2]. CME also maintains separate sections for delivery notices and warehouse/depository stock reporting, underscoring that the service providers XLS is the official rules-oriented dataset rather than a daily inventory report [5] [6].
4. How the spreadsheet has been used and interpreted by market commentators
Independent precious-metals analysts and trade press have relied on the service-providers XLS to document large additions or changes to eligible silver and gold brands, and some commentators frame those expansions as significant for market mechanics or delivery flexibility—interpretations logged in outlets that examined the spreadsheet after CME updates [4]. Those interpretations represent an analytical layer built on the raw XLS; the file itself lists brands and service-provider metadata, while arguments about market impact are conclusions drawn by external observers [1] [4].
5. Practical verification and caveats for researchers
The fastest way to verify current eligible SI brands is to download CME’s service-providers.xls from the CME rulebook files page and inspect the “Silver (SI) Brands” tab, and to cross-check any recent market notices that announce immediate effective changes [1] [2]. For complementary data—such as physical stocks or delivery notices—CME publishes separate Excel reports and delivery/stock pages that analysts often use alongside the brands XLS to understand operational implications [3] [5]. If further provenance or historical brand-change tracking is required, CME’s historical notices and registrar/clearing pages are the next authoritative sources to consult [6].
