Buyer-desk playbook · EN

Diagnose, qualify, model, act.
Four steps, one snapshot.

The full buyer-desk playbook in four moves: diagnose concentration against the snapshot, qualify the backup supplier against the reorder-point trigger, model landed-cost ROI on the next PO, and act on tariff shifts inside the first 48 hours. Every guide below ships the math, the worked example, and what shows up on your desk.

1. 01

   Diagnose concentration

   Run the four-line ROI calculator against your top-vendor share and turn single-mill exposure into an annual dollars-at-risk number the CFO can defend.

2. 02

   Qualify backup supplier

   Compute the metal reorder point the desk trusts — lead time, safety stock, daily burn, and the hidden fifth variable, single-mill concentration.

3. 03

   Model landed-cost ROI

   Price the next PO at landed cost — unit + freight + insurance, × tariff + brokerage, with a worked per-ton delta against the Section 301 line item.

4. 04

   Act on tariff shifts

   Run the first-48h playbook on every Section 232 / 301 line item — re-quote, origin-audit, model the delta — and follow the 30–60-day ripple into the next bid cycle.
