Quick Answer
Quick Answer
Every GCC country requires a third-party Conformity Certificate (SABER SCoC for Saudi Arabia, ECAS for UAE, QGOSM certificate for Qatar, etc.) alongside the mill MTC. Without the conformity certificate referencing the correct standard and grade, steel will be held or rejected at the port regardless of how complete the MTC is. Prepare the document package before the vessel loads.
Exporting structural steel or rebar to the Middle East requires more than a clean mill test certificate. Every GCC country operates a mandatory conformity marking scheme, and each has its own registration platform, recognized Conformity Assessment Bodies (CABs), and customs clearance workflow. Understanding the country-by-country requirements — and the most common reasons for port rejection — saves substantial cost and delay.
This guide covers the practical compliance requirements for exporters targeting Saudi Arabia, UAE, Qatar, Kuwait, Bahrain, and Oman. It focuses on the documents needed, not the product standards themselves. For full technical specification data, see the related pages below.
Why Port Rejections Happen
Steel shipments to GCC ports are rejected or held at customs for a predictable set of reasons. In 2024–2025, the most common causes reported by freight forwarders and importers were:
- Missing or expired conformity certificate: The Shipment Certificate of Conformity was not issued, was expired, or referenced a different product type than what was shipped.
- Grade mismatch: The MTC states a grade not covered by the Product Certificate of Conformity (e.g., MTC says S355J2 but the ECAS certificate only covers S355JR).
- Heat numbers not on the SCoC: The SCoC references generic product types but the specific heat numbers in the shipment were not listed.
- Standard reference missing from MTC: The MTC does not cite the applicable national or GSO standard — it cites only the mill's internal specification or a foreign national standard not recognized by the destination country.
- Discrepancy between invoice and MTC: Commercial invoice states Grade 60 rebar; MTC says B420B — same product, different naming convention, but customs systems flag the mismatch.
- Language of documents: Some GCC customs desks require English-language MTCs. Documents in Chinese, Korean, Spanish, or other languages without certified translation cause clearance delays.
- No country of origin certificate: Required for customs duty calculation and preferential tariff determination. Missing or mismatched origin certificates cause independent delays.
- Digital registration not completed: Saudi Arabia (SABER), UAE (ESMA portal), and Qatar now verify conformity certificates against national databases in real time. An otherwise valid paper certificate fails if the online registration was not completed.
Country-by-Country MTC and Conformity Requirements
Saudi Arabia
Governing body: SASO (Saudi Standards, Metrology and Quality Organization) Conformity platform: SABER (saber.sa) Key standards: SASO 203 (rebar), SASO 2178 (structural sections), GSO 1618 (rebar — GCC channel)
Required documents:
- Mill Test Certificate citing SASO 203 or GSO 1618 standard number and edition
- Product Certificate of Conformity issued by SASO-recognized CAB (valid 2 years)
- Shipment Certificate of Conformity (SCoC) registered in SABER platform — customs verify this number online
- Pre-shipment inspection report (for first-time consignments or at CAB's discretion)
MTC must include: SASO/GSO standard reference, grade designation, heat number, bar diameter (for rebar), chemical analysis (ladle), tensile test results, bend test result, mill name/location, authorized signatory.
Arabic language: Not required for MTC. English is accepted. SABER SCoC is generated in English and Arabic through the portal.
Notes: Saudi Aramco projects require additional TWI stamp on MTC, impact test results, and full heat-traceability documentation. See SASO Steel Overview.
UAE (United Arab Emirates)
Governing body: ESMA (Emirates Authority for Standardization and Metrology) Conformity scheme: ECAS (Emirates Conformity Assessment Scheme) Key standards: UAE.S GSO 1618 (rebar), UAE.S EN 10025 (structural steel)
Required documents:
- Mill Test Certificate citing UAE.S GSO 1618 or UAE.S EN 10025-2 standard number
- ECAS Product Certificate of Conformity (valid 2 years) — from ESMA-recognized CAB
- ECAS Shipment Certificate of Conformity — verified online at esma.ae
- For Dubai projects: additional DM material approval submittal and arrival testing at DM-registered lab
MTC must include: UAE.S standard reference, grade (e.g., B500B or S355JR), heat number, chemical analysis, tensile results (ReH, Rm, Rm/ReH, Agt for rebar), bend test result, mill stamp.
Arabic language: English MTCs are accepted. ECAS certificates are bilingual Arabic/English.
Notes: CE marking is not equivalent to ECAS. Post-arrival certification is possible but expensive and time-consuming. ADNOC projects require additional third-party mill inspection. See ESMA UAE Steel Certification.
Qatar
Governing body: QGOSM (Qatar General Organization for Standards and Metrology) Key standards: GSO 1618 (rebar), GSO 2437 (structural steel) as adopted by Qatar Sustainability overlay: QSAS (Qatar Sustainability Assessment System) for government projects
Required documents:
- Mill Test Certificate citing GSO 1618 or GSO 2437
- Certificate of Conformity from QGOSM-recognized CAB
- For Qatar Foundation, Ashghal, or QRAIL projects: third-party inspection report from project-specified inspection agency, plus any QSAS documentation requirements
MTC must include: GSO standard reference, grade designation, heat number, chemical analysis, full tensile and bend test data, mill identification.
Arabic language: English MTCs accepted. Translation may be requested for government project submittals on a case-by-case basis.
Notes: Qatar operates a more project-level compliance regime than a purely port-of-entry system for large government projects. Ashghal (Public Works Authority) maintains its own approved materials register — mills must be pre-approved before supply to Ashghal-governed infrastructure.
Kuwait
Governing bodies: Public Authority for Industry (PAI); Kuwait Authority for Partnership Environment (KAPE) Key standards: GSO 1618 (rebar) as adopted by Kuwait; Ministry of Public Works project specifications Conformity mark: KOWSMD conformity stamp
Required documents:
- Mill Test Certificate citing GSO standard
- Certificate of Conformity from PAI-recognized CAB
- For Ministry of Public Works projects: approved material submittal, third-party inspection report
MTC must include: GSO standard reference, grade, heat number, chemical analysis, mechanical test results, mill stamp.
Notes: Kuwait's port-of-entry enforcement has historically been less digitized than Saudi Arabia or UAE. However, the Ministry of Public Works applies rigorous project-level review for government infrastructure contracts. Ensuring CAB recognition by PAI before shipment is critical — not all internationally accredited CABs are recognized in Kuwait.
Bahrain
Governing body: Bahrain Standards and Metrology Directorate (BSMD) under the Ministry of Industry, Commerce and Tourism Key standards: GSO 1618 and GSO 2437 as adopted by Bahrain
Required documents:
- Mill Test Certificate citing applicable GSO standard
- Certificate of Conformity from BSMD-recognized or Gulf-recognized CAB
- For EPC/construction projects: project-specific material approval through the consultant
MTC must include: GSO standard reference, grade, heat number, chemical and mechanical test data, mill identification.
Notes: Bahrain is a smaller market with strong reliance on consultants for material approval rather than centralized port enforcement. The main conformity risk is at the project level — consultant rejection of non-compliant MTCs — rather than customs detention.
Oman
Governing body: Oman Standards and Metrology Authority (OSMA) Key standards: GSO 1618 (rebar) and GSO 2437 (structural), with Oman Building Code references Conformity mark: OSMA mark
Required documents:
- Mill Test Certificate citing GSO standard
- Certificate of Conformity from OSMA-recognized CAB
- For Ministry of Housing and Urban Planning or Oman Road Authority projects: third-party inspection report, project-level submittal approval
MTC must include: GSO standard reference, grade, heat number, chemical analysis, tensile and bend data, mill details.
Notes: Oman Building Code (2021 edition) references GSO 1618 for rebar and requires B420B as minimum grade for reinforced concrete. B500B is increasingly specified on commercial and industrial projects. OSMA has strengthened market surveillance in recent years; non-conforming products found on-site are subject to mandatory removal orders.
The 8-Document GCC Export Cert Package
For any steel shipment to a GCC country, prepare these eight documents before the vessel loads:
| # | Document | Issued By | Notes |
|---|---|---|---|
| 1 | Mill Test Certificate (MTC) | Steel mill | One per heat or per lot; must cite applicable GSO/national standard |
| 2 | Product Certificate of Conformity | Accredited CAB | Covers product type, grade, mill; valid 2 years; must match MTC |
| 3 | Shipment Certificate of Conformity (SCoC) | Accredited CAB | Per consignment; references Product CoC; registered in national database |
| 4 | Third-Party Pre-Shipment Inspection Report | Inspection agency | Confirms product marking, quantities, sampling, condition at origin |
| 5 | Commercial Invoice | Exporter | Must state: standard reference (e.g., GSO 1618 B500B), grade, origin |
| 6 | Packing List | Exporter/shipper | Bundle-level breakdown: heat numbers, bar diameters, lengths, weights |
| 7 | Country of Origin Certificate | Chamber of commerce | Authenticated; required for customs duty and preferential tariff |
| 8 | Bill of Lading / Airway Bill | Carrier | Standard shipping document |
Supplementary documents for specific situations:
- ADNOC/Aramco projects: Third-party witness inspection report, PMI report, heat traceability map
- Seismic zone projects (Class C rebar): Extended mechanical test report showing Rm/ReH ratio within both bounds
- Impact-tested structural steel: Charpy test certificates at project-specified temperature
- Galvanized or coated bar: Coating test certificates per applicable standard
Arabic Translation Requirements
| Country | Arabic Translation of MTC Required? |
|---|---|
| Saudi Arabia | Not required for customs. English MTC accepted. Government projects may request Arabic translation of test data. |
| UAE | Not required. English-language MTCs universally accepted. ECAS certificates are bilingual. |
| Qatar | Not required for standard commercial projects. Government mega-project submittals may require Arabic. |
| Kuwait | English accepted. Ministry projects: English technical documents with Arabic cover letter/submittal. |
| Bahrain | English accepted throughout. |
| Oman | English accepted. Oman Building Code compliance submissions may require Arabic forms but technical data in English is standard. |
Practical guidance: always provide English MTCs as primary documents. Where Arabic versions are needed, have a certified technical translator (not a general translator) handle the chemical and mechanical data — mistranslation of limit values is a common error that delays approvals.
Common MTC Deficiencies That Cause Rejection
Beyond missing conformity certificates, these MTC content gaps cause project-level rejection even when customs clearance succeeds:
- No standard reference: MTC states only internal mill grade (e.g., "Grade 60" or "HRB500") without referencing the applicable GSO or national standard. The consultant cannot verify compliance without the standard citation.
- Chemical analysis missing elements: MTC shows C, Mn, Si but omits P, S, or CEV. GCC standards require all elements listed in the applicable table.
- Agt (uniform elongation) not reported: For GSO 1618 rebar, Agt is a mandatory property. MTCs from mills following ASTM A615 convention (which does not require Agt) may omit it, causing rejection on GCC projects specifying GSO 1618.
- Rm/ReH ratio not stated: Required for Class B and Class C rebar under GSO 1618. If not pre-calculated on the MTC, buyers must verify it manually — and many do not.
- Multiple heats on one MTC: GCC project specifications typically require one MTC per heat per diameter. A combined MTC covering multiple heats is often rejected by site consultants.
- Tensile test specimen size not stated: EN 10025 and GSO 2437 require elongation to be reported on a gauge length of Lo = 5.65√So. If the gauge length is not stated, the elongation value cannot be verified as specification-compliant.
- Mill not identified: Some MTCs carry only a logo or partial name. GCC projects require the full mill name, location (country and city), and ideally the mill's accreditation number for the relevant standard.
Frequently Asked Questions
How far in advance should I start the conformity certification process before my first GCC shipment?
Allow 10–16 weeks for the full process if your mill is not yet certified for the destination market. This covers CAB selection (2 weeks), product registration (2–3 weeks), laboratory testing (2–4 weeks), factory audit (schedule-dependent, typically 2–4 weeks), and certificate issuance. If you need to ship within 8 weeks, engage a CAB immediately — some can expedite the process for established mills with existing ISO or EN certifications.
Can one CAB handle conformity certification for all six GCC countries simultaneously?
Yes. Major international CABs (Bureau Veritas, SGS, Intertek, TÜV Rheinland, RINA) hold recognition across multiple GCC national authorities. A single product assessment can support parallel applications to SABER, ESMA, QGOSM, and others. Confirm the CAB's recognized scope for each country before engaging, as recognition does not automatically apply to all product categories in all countries.
Our mill already has ISO 17025 accredited test reports. Does that satisfy GCC conformity requirements?
ISO 17025 accreditation of your internal lab covers the testing quality aspect. It does not replace the third-party product certification requirement. GCC conformity schemes require an independent, accredited CAB to issue the Certificate of Conformity — the CAB may use your ISO 17025 test data as supporting evidence, but they must independently verify and certify the product.
What is the shelf life of a Product Certificate of Conformity, and what triggers renewal?
Product Certificates of Conformity for GCC markets are typically valid for 2 years from issuance, subject to satisfactory surveillance audits. Renewal requires a new factory assessment and may require repeat product testing. Changes to the production process (new raw material source, different rolling mill, modified chemistry) must be notified to the CAB and may require interim testing before the certificate can continue to be used.
Do we need a new Shipment Certificate of Conformity for every truck or container, or just each vessel?
A Shipment CoC is issued per consignment, which is typically one vessel/container load or one purchase order shipment. If one vessel carries multiple purchase orders, separate SCoCs per order are best practice. The SCoC must reference the specific heat numbers and quantities in that consignment — a generic SCoC not tied to specific heat numbers is frequently rejected.
