Just-in-Time Replenishment vs International Lead-Time Risk
Design lead-time buffers around customs clearance and sanctions-screening variability so JIT replenishment plans account for mandatory regulatory dwell time.

Regulations
Business Context
Just-in-time replenishment reduces inventory and working-capital requirements by synchronizing supply closely with consumption. International sourcing introduces long transit times, customs processes, variable transportation schedules, and disruption exposure that can make precise synchronization difficult. Large protective inventories solve the uncertainty but undermine the economic objective of just-in-time operations.
Import Export TRIZ Resolution
Organizations can apply just-in-time principles selectively according to replenishment reliability. Stable flows can operate with short inventory horizons, while vulnerable products use targeted buffers, alternative sources, flexible transportation, or intermediate inventory positions designed specifically around identified lead-time risks.
Applicable TRIZ Principles
Principle 1 – Segmentation differentiates replenishment strategies according to lead-time reliability.
Principle 11 – Beforehand Cushioning maintains targeted protection against identified international variability.
Principle 15 – Dynamics adjusts replenishment parameters as supply conditions change.
Expected Outcome
Lower inventory
Greater replenishment reliability
Better working-capital efficiency
Reduced shortage exposure
Decision Indicators
Early indicators that this contradiction is limiting supply performance include:
Small transportation delays create immediate shortages.
International products use inventory targets designed for domestic lead times.
Just-in-time initiatives depend on perfect carrier performance.
Emergency freight increases after inventory reductions.
Lead-time variability is not incorporated into replenishment design.
Monitoring these indicators helps organizations capture just-in-time benefits without assuming international replenishment conditions are perfectly stable.
