Understanding Free Time Intervals

Free time intervals in Portmasters work on a progressive pricing model.

Day count calculation

• Counting begins from the container availability date at the terminal.
• Each day within an interval is charged at that interval’s rate.
• Intervals are consecutive and should not overlap.

Pricing strategy

• Initial days are typically free (e.g., 0–10 days at $0).
• Charges increase progressively to encourage timely pickup.
• Higher pricing in later intervals discourages extended storage.
• 40’ containers typically cost more than 20’ containers due to space usage.

Common interval structures

• Short free time – 3–5 days free, then daily charges.
• Standard free time – 7–10 days free, then tiered charges.
• Extended free time – 14+ days free, then premium charges.
