If you searched for american air cargo, you need specifics, not brochures. Here they are — and Masar turns them into a working shipment.
Start from the framework: Air cargo lands at Riyadh (RUH), Jeddah (JED) and Dammam (DMM) in 2–5 days door-to-door: China $2–6/kg, Europe $2.5–5, India $1.5–4. Billing uses chargeable weight — the greater of actual and volumetric (cm³ ÷ 6000). Airport customs clears in hours to one working day with certificates ready.
On the the USA lane specifically: sea freight to Saudi ports takes 25–40 days and air 3–7 days; typical cargo includes industrial equipment, medical devices, vehicles and spare parts, specialty foods. Main routings: New York, Savannah or Houston to Jeddah; West Coast cargo routes via transshipment. US–Saudi shipments are document-heavy: medical devices and vehicles carry extra conformity steps, and transit is the longest of the main corridors. Air freight at 3–7 days is the standard choice for urgent industrial spares.
For american air cargo, the difference between a smooth shipment and an expensive one is preparation before arrival.
Leave your number — a specialist replies within 30 minutes during Saudi working hours.
