Not all products earn their shelf space—how to use margin visibility to drive smarter SKU decisions.
In glass, ceramics, and refractories distribution, top-line revenue is meaningless without margin integrity. Yet many distributors build out SKUs based on customer requests or competitor offerings, not on actual profitability. The result? A sprawling catalog where high-volume, low-margin products subsidize niche lines that barely break even.
Enter margin tiers: a method for evaluating, categorizing, and managing your SKUs based on real contribution—not just sales price.
Tiering by Margin: A Practical Framework
Start by calculating the net margin per SKU after factoring in:
Landed cost (freight, import duties, handling fees)
Storage costs (especially relevant for large-format glass or heavy refractory blocks)
Picking and packing complexity
Return rates (more common with fragile or precision ceramics)
Then, assign SKUs to three buckets:
Tier 1: High-margin SKUs (>35% margin), often customized, low-touch, or tied to service contracts.
Tier 2: Mid-margin SKUs (20–35%), typically standard items with predictable volume and low friction.
Tier 3: Low-margin SKUs (<20%), often commoditized, price-sensitive, or costly to fulfill.
1. Prioritize Tier 1 SKUs for Stocking and Promotion
These are your catalog heroes—whether it’s high-purity fused silica plates, custom-laminated safety glass, or engineered refractory anchors. Promote them, train your sales teams on their value propositions, and ensure robust stock levels.
2. Watch Tier 2 Items for Margin Erosion
These often start strong but decline under price pressure or rising input costs. Review them quarterly. Can vendor terms improve? Is pricing outdated? Can a more efficient supplier reduce freight costs?
3. Manage Tier 3 SKUs with Caution
Some low-margin SKUs may be necessary to retain key clients (e.g., low-cost castables bundled in a refractory package). But many are legacy holdovers that no longer make sense. Identify where to:
Increase price with minimal churn
Move to special-order status
Sunset altogether with customer notice
4. Cross-Reference with Volume and Strategic Value
Not every low-margin SKU should be cut. Some serve as gateways into accounts. But margin tiers help you justify which ones stay and which ones go. For example, a high-volume low-margin ceramic gasket might stay if it supports a broader package sale, while a one-off oversized float glass panel with <10% margin is likely a net drain.
5. Train Your Teams on Margin Awareness
Sales reps often chase volume. Equip them with margin tier data so they can pitch Tier 1 products and avoid discounting items that are already margin-thin. In one North Carolina glass operation, this shift led to a 4.2% margin lift in just one quarter.

SKU planning without margin visibility is like flying blind. In today’s glass, ceramics, and refractories market—where freight, energy, and raw material costs can swing 20% in a quarter—profit protection begins with product mix management. Margin tiers offer a practical, actionable tool for aligning your catalog with your bottom line. Use them. Your P&L will thank you.
