Metal detectors for food in Saudi Arabia are the conveyor, gravity and pipeline inspection systems that Saudi plants use as the metal contamination CCP in the HACCP certificate SFDA licensing relies on. This page explains which type suits dates, bakery, dairy, poultry and grain lines, how to specify sensitivity and fail-safe rejects, what applies on import as of 2026, and what moves cost and delivery, above the supplier listings.

Choose the detector by how the product travels: packs on a belt, free-falling bulk, or pumped product in a pipe. Each format belongs within food safety and quality equipment in Saudi Arabia, and each finds ferrous, non-ferrous and stainless steel with a balanced coil and an automatic reject.
| Format | Saudi applications | Specify |
|---|---|---|
| Conveyor detector | Packed dates and date paste, bread and pastries, frozen poultry portions, cartons of laban and cheese | Aperture, belt and reject type, washdown rating, product temperature range |
| Gravity detector | Rice, flour, sugar, spices, coffee and cardamom ahead of filling | Throat diameter, throughput, reject flap speed, dust-tight housing |
| Pipeline detector | Minced meat, sauces, tahini, liquid dairy and fruit preparations | Pipe size, pressure, product temperature, hygienic connections |
| Detector on a VFFS bagger | Snacks, nuts and sweets weighed on a multihead weigher | Throat aperture, signal interface with the bagger |
| Metal detector and checkweigher combination | Retail packs for supermarket chains | One frame, shared data, see checkweighers for Saudi food lines |
Upstream, the detector depends on the fillers and baggers listed under food packaging equipment in Saudi Arabia; on dairy lines it follows the filling stage of dairy processing equipment.
Specify sensitivity as test sphere sizes for ferrous, non-ferrous and stainless steel 316 detected in your product at your line speed, and specify a reject system that cannot let a contaminated pack through unnoticed. Ferrous is easiest to detect and 316 stainless usually hardest; a smaller aperture improves all three.
Saudi plants supplying retail chains or export customers are often audited against retailer codes of practice. A 2019 Thermo Fisher summary of the Marks and Spencer code sets targets by aperture height, for example 1.0 mm ferrous, 1.2 mm non-ferrous and 1.5 mm stainless 316 for apertures of 25 to 75 mm, and up to 1.5 mm, 2.0 mm and 2.0 mm for 125 to 175 mm. Larger figures are acceptable only with documented product effect or metallised packaging. Use these as a benchmark, not a Saudi rule.
Moist dates, fresh and marinated poultry, white cheese in brine and fresh bread all carry product effect that a single frequency head mistakes for metal. Multi-frequency detectors reduce this. Packs in aluminium foil or metallised film are better inspected before packing or with X-ray inspection machines in Saudi Arabia.
Saudi conditions mainly affect metal detectors through product temperature, condensation and dust. Inland plants in Riyadh, Al Kharj and Al Qassim see dry heat and fine dust; coastal plants in Jeddah, Dammam and Jubail see humidity and salt air.
As of 2026, Saudi rules do not set a sensitivity figure for food metal detectors. The requirement comes through the HACCP certificate that the SFDA licensing guide asks manufacturers to hold: if metal is a significant hazard, the detector is controlled, monitored and recorded as part of that certified system.
| Item | What it means for the detector | Authority |
|---|---|---|
| Accredited HACCP certificate for the operating licence | Detector documented as a CCP or control measure with critical limits and verification | SFDA |
| Accreditation of certification bodies and laboratories | Who audits your HACCP or FSSC 22000 system and who calibrates reference equipment | Saudi Accreditation Center (SAAC) |
| Import conformity for regulated products | Whether a detector needs product and shipment certificates on SABER depends on the technical regulation covering it | SASO, SABER platform |
| Retailer and scheme audits | Fail-safe features, test frequency and documented sensitivity | Customer codes; FSSC 22000 and other GFSI schemes |
Ask the supplier to confirm the SABER classification before shipping; our guide to SASO and SABER certificates for industrial equipment lists what to request. A HACCP consultant in Saudi Arabia can set the critical limits and test routine.

Cost follows detection technology, aperture and the reject package; lead time follows whether the unit is a standard model or built to your line, plus import clearance.
