Last week I went through a Saudi seller's 2026 3PL invoices with him. One line item — "minimum monthly volume shortfall" — had cost him SAR 110,000 across the year. He never knew it was in the contract.
The most expensive part of a Gulf 3PL contract is not the unit rate. It is the commitment. The usual wording: minimum XX pallets handled per month, with the shortfall billed at 40% of the difference. Exceed it in peak and nobody credits you. Miss it in the slow months and you pay. My rule: sign at 70% of your lowest month in the past 12, or push for a quarterly true-up so the gap carries forward.
Second trap is how storage is measured. Pallet, cubic metre or bin position — the three can differ by 30%. Riyadh standard warehousing in 2026 quotes SAR 28-35 per sqm per month, up roughly 20% year on year. Pin down the measurement date in writing: taken at inbound, or at monthly stock count. Stack higher and your invoice climbs with it.
Inbound surcharges get overlooked. Off-slot arrival, unloading overtime, no ASN, non-compliant carton labels — each one has a price, SAR 5-15 a carton. In a full warehouse during peak, these can be 10% or more of the total bill.
Check destruction and return clauses too. Disposal of dead stock runs SAR 0.5-2 per unit plus environmental fees. Who pays the ocean freight on returns to China? If it is not written, it is you.
One more: liability. Most contracts cap loss at a fixed amount per kg or per unit, with a deductible attached. Read that line before you sign, not after a pallet goes missing.
Honestly, for 2027 contracts I would insist on two things: a cap on annual rate increases, 8% is reasonable, and 90 days' notice. Gulf rents are still climbing. Without a cap, next year's invoice will be a shock.
So what is in your 3PL contract — a monthly minimum, or a quarterly true-up?
