Use NAVSUP 1364 to modify the Item Cataloging Reference List (ICRL) in Navy logistics.

The Navy’s logistics world runs on clean data. If you’ve ever tried to locate a part, track a repack date, or verify a catalog entry, you know that a single incorrect field can ripple through the supply chain. That’s why the Item Cataloging Reference List (ICRL) matters—and why the form you use to modify it matters just as much. In short: when you need to adjust what’s in the ICRL, NAVSUP 1364 is the form that makes it official.

What exactly is the ICRL, and why do we need it?

Think of the ICRL as the authoritative directory for cataloging items in the Navy’s logistics system. It’s the backbone that keeps inventory, requisitions, and cataloging aligned across ships, supply depots, and procurement offices. When an item’s description, unit of issue, or catalog number changes, those updates have to flow through the right channels so everyone speaks the same language. That’s where form NAVSUP 1364 comes into play—it’s designed specifically to document and process those modifications.

NAVSUP forms at a glance: what each one does

To keep this clear, here’s a quick map of the forms you’re likely to encounter and why they aren’t interchangeable for ICRL edits.

• NAVSUP 1364: The modification form for the ICRL. This is the one you use when you’ve got to add, correct, or remove catalog data. It captures the fields that matter for catalog updates and routes the request to the proper authorities so the changes take effect in the data system.

• NAVSUP 1345: This form is the go-to for supply support requests and related actions. It’s not the right tool for editing catalog entries. Think of it as a way to request services or support rather than to alter catalog data.

• NAVSUP 1363: A versatile form that covers cataloging and requisitioning in some contexts. While it touches catalog data, it isn’t the designated instrument for straightforward ICRL modifications. Its scope can overlap with other processes, which means using it for ICRL edits can create ambiguities.

• NAVSUP 1390: This one’s tied to logistics analysis—evaluation, performance, and more. It’s valuable for programmatic review, but not intended for routine catalog changes.

The core reason NAVSUP 1364 is the star for ICRL edits is simple: it’s purpose-built to capture the exact information needed to modify the catalog data, document why the change is necessary, and route the request through the correct approval chain. Using the right form helps guarantee consistency, traceability, and timely updates across the Navy supply system.

Why NAVSUP 1364 is the right tool for ICRL modifications

Let’s break down what makes 1364 the best choice, in practical terms.

• Precision of data fields: NAVSUP 1364 provides targeted fields for item description, unit of issue, packaging, catalog numbers, and other cataloging attributes. When you’re updating an ICRL entry, you want precision, not a long list of extra fields that can confuse the process.

• Clear justification: Catalog updates aren’t just administrative; they affect how repairs are stocked, how parts are ordered, and how items are identified in storerooms. The form includes space to explain the reason for the change, which helps reviewers understand the impact and avoid back-and-forth clarifications.

• Proper routing and approvals: The Navy’s logistics network relies on a well-defined routing path. The 1364 flow is designed to move through the right offices—cataloging, item data control, and the appropriate supply channels—without getting bogged down in unrelated workflows.

• Auditability: Edits to the ICRL must be traceable. A properly completed 1364 creates an auditable record: who requested the change, what was changed, when, and why. That kind of trail matters when ships or depots rely on consistent data in real time.

A practical example: what a NAVSUP 1364 entry might look like

Imagine you’re updating an item that moved from one catalog number to another because of a packaging change. The 1364 form would capture:

• The current catalog reference and the proposed modification

• New item description(s) and any updated unit of issue

• Rationale for the change (e.g., updated manufacturer data, revised packaging, or corrected dimensions)

• Supporting documentation (supplier bulletins, technical data, or inspection reports)

• The owner or approving authority responsible for the change

With those details, the modification request travels through the channels designed to interpret catalog data and apply the update across the Navy’s logistics systems. The result is a single, coherent change reflected in the ICRL that all users can rely on—hence fewer mismatches at the point of requisition or issue.

Why not use the other forms for ICRL edits?

Here’s the practical angle. You wouldn’t use a hammer to tighten a bolt; you’d pick the right tool for the job. In the same spirit:

• NAVSUP 1345 is great for requesting support or reporting issues, but it lacks the cataloging-focused fields and routing that an ICRL modification requires. It’s a broader container for supply actions, not a precise instrument for catalog changes.

• NAVSUP 1363 covers cataloging and requisitioning in a broader sense. While it touches catalog data, using it for direct ICRL edits can blur accountability paths and complicate data integrity.

• NAVSUP 1390 is a logistics analysis instrument. It’s excellent for performance evaluations and program insights, but it’s not designed to carry the exact catalog modification payload you need for the ICRL.

When you stick to NAVSUP 1364 for ICRL edits, you’re aligning with the Navy’s data governance. That alignment matters. If you’re managing parts for a ship, a squadron, or a maintenance depot, consistent catalog data accelerates ordering, reduces wait times, and minimizes the risk of wrong items being issued.

Best practices for clean, effective ICRL updates

A few practical tips to keep your ICRL edits smooth and verifiable:

• Gather solid supporting data: Before you submit 1364, collect the evidence that justifies the change. That might be a supplier bulletin, a tech data sheet, or an inspection report. Attach it so reviewers don’t have to hunting for references.

• Be explicit about the impact: Describe exactly how the modification affects the item’s description, unit of issue, packaging, or catalog numbers. Clear impact statements reduce back-and-forth and speed processing.

• Check for cross-references: Catalog changes can ripple into related entries. Verify there aren’t conflicting edits in parallel requests and ensure related lines stay in sync.

• Maintain a tidy record: Keep a copy of the submitted form and all attachments. In the Navy’s data ecosystem, traceability isn’t optional—it’s essential for audits and future updates.

• Confirm approval and implementation: After submission, monitor the workflow to confirm the modification is approved and implemented in the ICRL. If there’s a delay, follow up with the respective data control authority, but with a courteous, concise message—people are busy, and a clear note helps move things along.

Connecting the dots: why this matters in daily Navy logistics

The ICRL isn’t a flashy dashboard feature; it’s the quiet backbone you rely on when you’re stocking a warehouse, provisioning a ship, or restoring a damaged system. When a catalog entry is accurate, requisitions flow smoothly, maintenance teams don’t wait on backorders, and supply lines stay predictable. It’s the difference between a well-oiled machine and a bottleneck that slows a crew down mid-deployment. And in a context where every item has a specific part number, unit of issue, and packaging instruction, accuracy isn’t a luxury—it’s a lifeline.

A quick mental model you can carry

Think of the ICRL like a city map for goods. If a street name changes or a block is re-zoned, you’ve got to update the map so everyone can navigate without detours. NAVSUP 1364 is the official map-editing tool for those changes. It keeps the city coherent, traffic flowing, and emergency services able to reach the right location without confusion. The other forms are useful for their own purposes—think of them as alternative maps for different journeys. But for ICRL edits, 1364 is the one that preserves accuracy across the system.

Key takeaways to remember

• ICRL modifications should be done with NAVSUP 1364. It’s the form designed for catalog changes and data integrity.

• NAVSUP 1345, NAVSUP 1363, and NAVSUP 1390 serve other purposes and aren’t replacements for ICRL edits.

• Clear justification, complete supporting documentation, and proper routing speed up processing and ensure accurate updates.

• A well-maintained ICRL helps keep inventory aligned, requisitions timely, and maintenance operations uninterrupted.

A final thought: data you can trust

In the end, the value of a single form isn’t in its paper weight or the numbers it contains. It’s in the confidence it gives the entire supply chain: confidence that what’s listed in the ICRL matches what’s on the shelf, what’s in the warehouse, and what’s required for ongoing operations. When you choose NAVSUP 1364 for ICRL changes, you’re choosing clarity, accountability, and efficiency. It’s a small step with a big payoff—the kind of step that keeps ships ready, crews fed, and systems humming.

If you’re ever unsure which form to pull, remember the same rule of thumb: use the tool that speaks directly to the data you need to edit, and keep the process lean, transparent, and well-documented. In Navy logistics, that’s how accuracy turns into readiness.
