The majority of supply chain disruptions originate below Tier 1, yet many OEMs have little or no visibility below their direct suppliers. Z2 traces every BOM component to its raw material source, surfacing single-source nodes, geographic concentrations, and cross-program dependencies before they cascade to your production floor.
How It Works
Upload your BOM and Z2 immediately begins tracing every component through its complete supplier chain (Tier 1 distributors, Tier 2 manufacturers, Tier 3 fabricators, and raw material sources) using an extensive proprietary database of supply chain relationships.
Upload a BOM or sync live from your ERP or PDM. Z2 resolves every part number against our 1B+ component database on the spot. No manual mapping. No supplier outreach. Instant coverage.
Z2's knowledge graph traces each component from manufacturer to fab to substrate source to raw material supplier, building a complete, layered supply chain tree for every line item in your BOM.
Single-source nodes, geographic concentration hotspots, and cross-program dependencies are prioritized by severity, so your team focuses on what matters before a sub-tier failure reaches Tier 1.
Supply Chain Visibility
Most OEMs screen their direct suppliers and call it done. Z2 goes further, automatically building the complete supplier graph from your BOM, revealing the sub-tier nodes where real concentration risk lives. Single-source dependencies surface before they trigger a shortage.
Capabilities
Trace every BOM line item from Tier 1 to raw material source with each node scored for disruption risk, starting on day one rather than after months of manual data collection.
Flag every component, substrate, and raw material routing through a single supplier, including dual-sourced Tier 1s that secretly converge on the same Tier 2 or Tier 3 node.
Map sub-tier exposure by country, region, and geopolitical risk zone, ranked by revenue at risk across every active program before your CFO asks.
When a sub-tier node is disrupted, Z2 instantly calculates the blast radius across affected programs, exposed BOMs, and revenue at risk before it ever reaches your Tier 1 suppliers.
Surface every sub-tier node shared across programs so you can see where one failure cascades company-wide and prioritize mitigation where overlap is greatest.
Native connectors for SAP, Oracle, Arena, and Agile PLM push sub-tier risk scores and supplier graph data straight into the workflows your procurement and engineering teams already use.
Use Cases
Your two Tier 1 suppliers look like protection on paper. But if both buy substrates from the same Tier 3 fab in Hsinchu, you are single-sourced. You just don't know it yet. Z2 finds the node where your real concentration lives.
When trade policy changes or a regional event fires, Z2 immediately shows which programs are exposed, ranked by revenue at risk, mapped to the specific sub-tier node. Stop building these reports manually after the fact.
Sub-tier exposure scores roll up to program and business unit level automatically. Eliminate the manual supplier tree exercises before your quarterly S&OP or board risk review. Walk in with data, not estimates.
Acquisition targets routinely carry sub-tier concentration risks that standard diligence never surfaces. Z2 maps the full supplier graph of any BOM portfolio in days, not months, giving you leverage before you sign.
Common Questions
Z2 Sub-Tier Intelligence resolves every BOM line item against a 1B+ component database and an internal relationship graph, tracing each part from manufacturer to fab to substrate and raw material source. It builds the full supplier tree from your BOM alone, with no supplier outreach required to start.
Yes. Two Tier 1 suppliers can look like protection on paper while both buy substrates from the same Tier 2 or Tier 3 fab. Z2 flags every component, substrate, and raw material routing through a single node, exposing the point where your real concentration risk lives.
Yes. Z2 infers sub-tier relationships from its internal database, so you do not need to know who your suppliers’ suppliers are, then screens those entities against the UFLPA Entity List and 30 other sanctions lists. Exposed Tier 2 and Tier 3 suppliers are flagged automatically with the BOMs they affect.
Z2 maps sub-tier exposure by country, region, and geopolitical risk zone, then ranks it by BOM value at risk across every active program. When trade policy shifts or a regional event fires, you see which programs are exposed and where, instead of rebuilding supplier trees by hand.
Yes. Native connectors push sub-tier risk scores and supplier graph data into systems your teams already use, including SAP, Oracle, Arena, and Agile PLM. You can sync a BOM live or upload it directly, and Z2 resolves every part number against its component database on the spot.
"There are many pitfalls in supply chains now; you can run into a discontinued component and regularly see delays. Z2 fills a critical gap for our purchasing, helping us build a more robust supply chain model on the inflow side, so we don't end up with stoppages."
