Duplicate and near-duplicate SKUs are hiding in your system—costing you warehouse space, customer clarity, and real dollars.
Overlapping SKUs are among the most common hidden inefficiencies in Glass, Ceramics, and Refractories distribution. They confuse internal teams, muddle customer orders, and inflate inventory without adding value. And they often go unnoticed until a product audit reveals just how many “different” SKUs are actually serving the same function.
Let’s define overlapping SKUs: These are item codes that, while technically distinct, fulfill the same customer need. In glass, this might mean two laminated panels with the same safety rating and thickness, but different code names due to vendor or tint variation. In ceramics, it could be three alumina crucibles with only minor dimensional differences. In refractories, it’s common to find several low-cement castables with nearly identical thermal profiles but different labels.
So how do you flag them?
1. Run Attribute-Based Audits
Most ERPs can export SKU-level detail by key attributes. Run reports filtered by product family, then sort by dimensions, material composition, temperature rating, and origin. Any groupings with ≥90% similarity are red flags.
2. Cross-Check Customer Orders
Overlay order data with customer profiles. If multiple SKUs are being used interchangeably by the same buyer—or across similar use cases—that indicates unnecessary differentiation.
3. Use the ‘Choice Without Difference’ Test
Have product specialists or sales reps evaluate side-by-side SKUs and ask: “Would the average customer care if we substituted this?” If the answer is no, consolidation is in order.
4. Flag Vendor-Induced Duplication
Many overlaps stem from multi-sourcing. If you carry two 2″ firebricks from different suppliers that perform identically but sit under different SKUs, consider unifying them with a supplier-neutral code. Track vendor at the PO level, not SKU level.
5. Filter by Pick Rate
Overlapping SKUs often dilute pick efficiency. Analyze warehouse pick data—if two items are often picked in place of each other or generate mis-picks, that’s a signal your staff sees them as interchangeable even if the system doesn’t.
6. Create a SKU Rationalization Protocol
Once overlaps are identified, assign each one a retirement plan: consolidate under one code, move to made-to-order, or phase out. Communicate the change clearly to your sales team and update all customer-facing materials.
Addressing overlaps isn’t just about cleaning house—it’s about protecting margin. Every redundant SKU adds cost: in replenishment, in warehousing, in training, and in customer confusion. Left unchecked, they erode the scalability of your operation.

SKU overlap is like digital plaque—it builds slowly, invisibly, and can be costly if ignored. With structured audits and smart consolidation, Glass, Ceramics, and Refractories distributors can improve efficiency, sharpen catalog focus, and avoid inventory redundancies that eat into profitability. Don’t wait for chaos to force your hand. Audit now, consolidate smart, and let every SKU earn its place.
