Why too many “lookalike” SKUs are quietly draining your margin, space, and service efficiency.
In ceramic distribution, redundancy rarely looks like a problem at first glance. Distributors pride themselves on breadth of offering—whether it’s 99.8% alumina tubes, cordierite kiln furniture, or sintered mullite tiles. But when two, three, or even five SKUs serve the same customer use case, you’re not offering variety—you’re cannibalizing your own profitability.
SKU duplication is one of the most underestimated forms of operational waste in ceramic supply. It tends to emerge over time through customer-specific customizations, supplier over-accommodation, or rapid-fire onboarding of new product lines without rationalization. Before long, your catalog becomes an unwieldy maze—filled with “same-but-different” items that bloat your ERP, slow down order picking, and fragment purchasing power.
Let’s take a practical example. One U.S. ceramics distributor audited its technical ceramics line and found seven different SKUs for 2″ x 8″ alumina rods—varying by tiny differences in wall thickness, packaging unit, or legacy client codes. Only two of those SKUs accounted for 90% of orders. The rest had been created to appease one-off requests or marginal customizations. But all seven had to be inventoried, cycle-counted, stored, and managed.
This duplication caused:
Redundant stockholding (costing ~$18,000/year in working capital)
Inconsistent vendor MOQ fulfillment
Mispicks and slower order turns in the warehouse
Erosion of pricing leverage due to diluted volume per SKU
The corrective action wasn’t drastic. They merged the redundant SKUs, worked with clients to move toward standard specs, and offered engineered-to-order terms for outliers with longer lead times. Within 6 months, they eliminated over $70K in obsolete inventory and improved OTIF rates by 11%.
SKU duplication also impacts sales clarity. When your catalog contains three nearly identical zirconia tubes, even seasoned account managers spend extra time cross-referencing spec sheets. Worse, customers may get confused or choose suboptimal products simply because too many options cloud the value proposition.
What’s the fix? Start with these steps:
Run a product similarity matrix. Use dimensional, material, and application parameters to cluster SKUs that are functionally identical.
Overlay sales and client usage. Which duplicates are moving? Which are dormant? Which are legacy?
Work with your top clients. A SKU you created for a single job in 2019 might no longer be needed. Ask before you restock.
Engage procurement. Many duplicates arise from vendor-specific codes. Harmonize specs where possible to reduce duplication across suppliers.
Set guardrails. New SKU creation should require a business case—not just a customer request form.

SKU duplication is more than an annoyance—it’s a slow bleed on profit, warehouse efficiency, and vendor leverage. In ceramic distribution, where carrying costs are high and technical complexity adds to service demands, cleaning up duplicate SKUs can free up capital and improve order accuracy overnight. Trim the fat, and your catalog becomes a competitive weapon—not a liability.
