Capacity Constraints

When Your Packaging Supplier Can't Keep Up

Supplier capacity limits threaten fill rate and launches; buyers need overflow/second-source options.

Direct answer

When a packaging supplier hits capacity, options include qualifying an overflow/second source, adjusting order cadence, and buffering with stock; qualifying the backup before the crunch avoids allocation and line-down risk. Actions depend on the program's volumes and timing.

Why this matters

Supplier capacity limits threaten fill rate and launches; buyers need overflow/second-source options.

Turn capacity into quantities and dates

State the affected SKUs, inventory, consumption, firm need dates, open orders, and the production or promotion that cannot move. Ask what quantity is constrained, for how long, and which actions could change the answer.

  • Partial production or revised releases.
  • Approved substitution review.
  • SKU prioritization and allocation.
  • Qualified alternate manufacturing path.

Choose the response by risk

A schedule change may be enough for one item; another may justify accelerated qualification. Preserve the approval path and document temporary deviations.

Boundary: Capacity changes. Confirm it with the responsible supplier before making a customer or production commitment.
