Testing for Saudi exporters

A destination buyer’s technical reviewer reads a certificate of analysis the way an auditor reads a record: what was tested, by what method, against what limit, and who stands behind the number. A certificate that reports “complies” without naming the limit and its source gets queried, and a queried certificate holds the consignment. Every determination on a Nexus certificate is tied to the sample, the lot, the method and the limit you asked us to assess against.

Tell us at booking that the report is for export. We issue in English, name the limit source on the face of the certificate, and mark each determination as accredited or non-accredited, so the claim is precise rather than implied.

Sample identity

Your product already meets a home baseline — microbiological criteria under GSO 1016:2015, contaminants and toxins under SFDA.FD CAC 193, veterinary drug residues under GSO 2481. None of that guarantees the destination draws the same line for the same analyte. The commonest export failure is a batch tested against the home limit and shipped into a market that sets a different figure — the result was right, the comparison was wrong.

We do not keep a register of every destination rule, and we will not invent one. You name the destination limit and the document it comes from; the laboratory confirms in writing what it will test and report against before work starts. The determination is usually identical — it is the reporting line that moves.

Nutrition panels are where exporters pay twice without noticing. The analytical work behind a panel is the same whatever the market; what changes is presentation — units, rounding, reference quantities, the order of the table. GSO 2750:2024 fixes the home format. For everything else, the economical route is one determination set, presented in each format a destination requires, rather than a fresh analysis per market.

Commission the determinations once, at the depth your widest market needs, and hold the raw results. Each new market then costs a presentation exercise, not a laboratory campaign.

Serious buyers check accreditation claims against the published scope. Nexus testing is accredited by the Saudi Accreditation Center (SAAC) to ISO/IEC 17025:2017 for food and agricultural microbiology, certificate N-T-00607; calibration is accredited in the mass, mechanical, temperature and chemical fields under N-C-00592. Determinations outside those scopes are reported as non-accredited, and the certificate says so. That precision reads as weakness to a marketer and as competence to a reviewer.

If a buyer asks what the accreditation means, point them to the scope, not a slogan: an accredited result is one produced under a system a national accreditation body has assessed against ISO/IEC 17025:2017. What it does not say matters as much — see the guide in the rail below.

Accredited testing

Food and agricultural microbiology — N-T-00607

Accredited calibration

Mass, mechanical, temperature, chemical — N-C-00592

Non-accredited in-house

Dimensional and electrical calibration

Everything else

Reported and marked as non-accredited

When a consignment is rejected weeks after it left your dock, the argument is between the buyer’s laboratory and yours — and yours only counts if the sample it tested is defensibly the same product. A retained sample from the shipped lot, held under stated conditions with the chain of custody written down, is the cheapest insurance in exporting. It sits untested until there is a dispute; then it is the evidence.

Shelf life carries the same logic. SFDA.FD 150-1 and SFDA.FD/GSO 150-2 govern expiry dating at home, but a longer chain consumes the claim in transit — weeks at sea and in clearance come off the same clock as weeks on a shelf. A shelf-life study designed for export builds the voyage into the timeline instead of hoping the product ignores it. Where the destination expects a different dating convention, the laboratory confirms in writing what the study will support.

A consignment dispute is decided by the sample you kept, not the one that sailed.
