Not every product deserves a permanent shelf spot—here’s how top distributors draw the line between essentials and value drivers.
In the world of refractory, glass, and ceramics distribution, the weight of a bloated SKU list can drag down operations fast. Every product you carry—whether it’s a dense firebrick, a borosilicate pane, or a high-purity alumina tube—demands storage, forecasting, procurement, and attention. Yet not every product contributes equally to growth or profitability. That’s where portfolio segmentation comes in—specifically, the divide between core SKUs and strategic SKUs.
Core SKUs are the backbone of your business. They’re the materials you consistently sell across multiple customers and markets, and which typically have stable, predictable demand. Think 230x114x64mm firebricks for steel mill linings, standard soda-lime float glass sheets, or basic glazed ceramic tiles for retail contractors. They turn fast, carry reliable margins, and form the bulk of your day-to-day shipments.
Strategic SKUs, by contrast, are not about volume—they’re about value. These are products that may sell less frequently but play a critical role in client acquisition, retention, or differentiation. For example:
High-alumina monolithics used for petrochemical reformers
IR-reflective coatings on laminated architectural glass
Silicon carbide kiln furniture for high-performance thermal processes
They’re often the reason a customer chooses you over a competitor. They can open the door to long-term contracts or lock in custom work where you become a preferred supplier.
The problem arises when everything in the catalog is treated the same. Without segmentation, distributors often tie up capital in SKUs that are neither core nor strategic—products ordered once for a project five years ago, or niche materials added during a one-off client request. These “orphan SKUs” add cost but no strategic value.
So how should you segment?
Start with Velocity and Breadth
Use sales data to identify high-turn, multi-customer SKUs. These become your core. Don’t just look at sales dollars—look at order frequency and customer spread.
Map Strategic Fit
Identify SKUs that serve as market differentiators or are linked to long-term contracts. These should be flagged as strategic, even if their sales volume is low.
Evaluate Holding Costs
Any SKU not falling into either category should face scrutiny. What’s the carrying cost? Could it be fulfilled via special order instead of stocking?
Create Tiers and Treat Them Differently
Core SKUs should get priority for bulk purchasing, vendor consolidation, and inventory optimization. Strategic SKUs may need flexible sourcing models, drop-shipping, or supplier co-investment.
Review Annually—Not Just During ERP Upgrades
As projects evolve, SKUs shift tiers. Strategic SKUs can become core as demand spreads. Orphan SKUs can be sunsetted with client notice.

The key to profitability in materials distribution isn’t having the biggest catalog—it’s having the right one. When you define your core and strategic SKUs with intent, you not only serve customers better—you free up resources to invest in what moves the needle. Don’t let your warehouse become a museum of one-off projects. Segment, prioritize, and stay lean.
