Shrinking your catalog could be the smartest financial move you make this year.
Inventory ties up more capital than nearly any other line item for glass, ceramic, and refractory distributors. But many firms still treat SKU count as a growth metric instead of a risk factor. Whether you carry 2,000 or 20,000 SKUs, odds are that 25% of them generate less than 5% of your revenue—and that discrepancy is costing you.
SKU streamlining—the process of pruning your product catalog to reduce redundancy, dead stock, and customer confusion—is one of the fastest ways to improve your inventory ROI. Yet most distributors hesitate, fearing lost sales or customer dissatisfaction.
But consider the reality: over 70% of working capital in industrial distribution is locked in inventory. For companies distributing items like float glass, low-iron panels, high-purity ceramics, or refractory bricks, every SKU takes up floor space, requires counting, and dilutes purchasing leverage. The more SKU sprawl you have, the more fragmented your spend—and the harder it is to stock what actually sells.
Start With the SKU Value Pyramid
Sort your SKUs into four tiers:
A-tier: High-turn, high-margin items (your bread and butter)
B-tier: Moderate-turn, consistent sellers
C-tier: Low-turn, customer-specific or rarely requested items
D-tier: No sales in 12+ months
Run profitability and velocity reports across all tiers. If you’re like most distributors, 60% of your SKUs will fall in the C and D tiers. That’s where your streamlining starts.
Consolidate by Specification
Distributors often carry nearly identical products: 1.1mm vs. 1.2mm sheet glass, 9” vs. 10” kiln furniture, or two grades of high-alumina castables with minimal performance differences. Survey your customers and inside sales team. Would one variant suffice? If yes, consolidate and redirect purchasing volume to fewer suppliers for better pricing.
Leverage MOQ-Based Rationalization
For slow-moving SKUs that customers still occasionally request, adopt a MOQ (minimum order quantity) or lead-time buffer strategy. This allows you to preserve availability without holding on-hand inventory.
Implement a Streamlined Stock Policy
Move toward a stock vs. non-stock model, where only Tier A and B SKUs are kept in inventory. Non-stock items are ordered only with customer commitment. Many leading distributors have adopted this for specialty refractories or niche glass laminates.
Use Dead Stock as Leverage
That pile of aging borosilicate sheets or unused ceramic foam filters? Package them into clearance lots or use them as upsell incentives. Reinvest the recovered capital into high-velocity SKUs or tech upgrades.

Streamlining isn’t about limiting customer choice—it’s about eliminating operational drag. For glass and ceramics distributors, SKU discipline translates directly into margin, capital efficiency, and better fill rates. In today’s freight-sensitive, cash-tight environment, fewer SKUs may just be your fastest route to stronger ROI.
