The backup supplier strategy (or: why single-sourcing cores fails)
Single-sourcing paper cores is a silent line-down risk. How converters build a second-source program, what to qualify, and how a local reserve turns risk into uptime.
Cores are 2% of your BOM and 100% of your output: when the core bin is empty, the line is down, no matter whose fault the freight was. Yet most converters single-source them from one distant plant because the unit price looked right in 2019.
The failure modes are boring and regular: a snowstorm on I-80, a mill allocation, a truck that misses a dock window, a price increase you cannot refuse mid-contract. None are dramatic; all stop lines.
A real second-source program: qualify a second supplier on your top three core SKUs (samples, then one production order); keep them at 10–20% of volume so the relationship is warm; document the spec so either plant can run it; and locate the backup close enough that recovery is measured in days, not weeks.
The local upgrade: NHPT offers named-account core reserves — your SKUs, wound and shelved in Raymond, released on a phone call. It is insurance priced in tubes, and it makes proximity a contract term instead of a hope.

FAQ
Why should converters dual-source cores?
Because cores stop lines out of all proportion to their cost, and every distant single source carries freight, weather, and allocation risk you cannot control.
How much volume should a second source get?
Enough to stay qualified and warm — typically 10–20%, concentrated on your highest-risk SKUs.
What is a core reserve agreement?
A standing arrangement where NHPT winds and shelves your specific core SKUs in Raymond, guaranteed releasable on short notice.
