Set the deferral benefit against the cost of the payment environment on the same shipment.
An FMCG importer on 60-day contractual terms, paid at 100 days, is financing SR 1,207,500 for 40 days beyond terms. At a 7% cost of capital that is SR 9,263 — none of it recoverable.

Across the thirteen profiles, the ratio of late payment cost to bonded zone benefit has a median of 9.3:1 and a mean of 11.5:1. Aggregated across every shipment modelled, the total late payment cost is about 10.4 times the total deferral benefit. No profile at 60 days' dwell comes close to parity.
Read this correctly
These are not alternatives, and the comparison is not a net loss calculation. Using a bonded zone does not cost an importer SR 8,235. It leaves them SR 1,028 better off than they would otherwise be, while a separate and much larger exposure — one the bonded zone was never designed to address — continues to run.
The point of the comparison is scale, not substitution. A business that treats bonded zone deferral as its cash flow strategy is optimising a fraction of a percent while an exposure ten times larger runs untouched in accounts receivable. Both should be managed. Only one of them is usually being sold.
The break-even
There is a clean way to express how far apart the two sit. For the 60-day deferral benefit to match the 40-day late payment cost on this shipment, the duty rate would need to exceed roughly 80% of CIF value.
| Category | Duty or excise | Multiple below break-even |
| --- | --- | --- |
| Most imports | 5% | 16.1× |
| Trucks (built up) | 12% | 6.7× |
| Protected electrical | 15% | 5.4× |
| Seasonal vegetables | 25% | 3.2× |
| Dates, wheat flour | 40% | 2.0× |
| Tobacco | 100% excise | Clears the threshold |
|~ Break-even measured against the ~80% of CIF required to match the 40-day late payment cost at 60 days' dwell.
Saudi Arabia would need to tariff most imports at roughly sixteen times the current rate before bonded zone deferral matched the cost of getting paid late.
