SKU Overlap Between Brands: A Hidden Margin Killer

By Glazix | May 29, 2025

When two brands serve the same function, you’re not offering choice—you’re undermining your pricing power.

In the fragmented world of glass, ceramic, and refractory materials, distributors often pride themselves on carrying multiple brands. More choice equals better customer service—or so the thinking goes. But when that choice results in brand duplication for nearly identical SKUs, it’s not a value-add. It’s a margin leak.

Let’s say you carry ceramic tiles from both Brand A and Brand B. They offer the same size, glaze, and PEI rating—essentially interchangeable products. What happens? Your inside sales team starts offering both. Customers price-shop within your catalog. And suddenly, your margins erode as you’re forced to undercut… yourself.

The issue is compounded in technical ceramics and refractories. High-alumina crucibles from different OEMs often meet the same ASTM specs, as do insulating firebricks rated at 2600°F. If your team isn’t trained to lead with the higher-margin brand—or worse, if your pricing matrix doesn’t enforce consistency—overlap becomes a margin killer.

Overlap also creates logistical drag. You split purchasing volume across vendors, lose out on bulk pricing, and carry redundant safety stock. It inflates your catalog, increases pick errors, and clutters your ERP system with duplicate entries.

So how do you fix it?

Conduct a Redundancy Audit

List all items with functional equivalents across brands. Group by use case—e.g., kiln shelves, mullite tubes, zirconia liners—and compare SKUs spec-by-spec.

Measure Margin Differential

For each overlapping SKU, calculate your landed cost, average selling price, and GP%. If Brand A yields 38% and Brand B only 24%, your path is clear.

Pick a Champion Brand

Choose one primary brand per SKU category to lead with—ideally the one with the best combo of margin, availability, and vendor terms. The secondary brand can be offered as a back-up or phased out.

Train Your Sales Team

Sales needs scripts and pricing logic to defend the chosen SKU. Make margin preservation part of performance KPIs.

Monitor Customer Response

Some accounts may prefer Brand B for legacy or approval reasons. Offer it with pre-approval or custom quote logic—just don’t stock it broadly.

This strategy applies equally to refractory mortars, ceramic coatings, and even glass sheets. If multiple brands sit on your shelf doing the same job, they’re not serving the customer—they’re competing for your margin.

SKU overlap is the silent margin killer in distributor catalogs. For glass, ceramic, and refractory suppliers, trimming duplication between brands isn’t a cut in service—it’s a boost in profitability. The goal isn’t to limit choice—it’s to create smart, strategic choices that strengthen both customer trust and gross profit. In a world where pennies matter, don’t compete against yourself.
