SAEP-347 Compatible Suppliers Saudi Arabia — How to Choose a Stockist

Not every supplier who claims SAEP-347 compatibility can actually back it up. This guide covers the 7 criteria procurement engineers and EPC contractors should verify before placing an order — from material number coverage and EN 10204 3.1 documentation to local Saudi stock and sour service compliance.

Disclosure: Gulf Union Ozone is a SAEP-347 compatible stockist and one of the suppliers described in this guide.

The Standard

What SAEP-347 Actually Requires from a Stockist

SAEP-347 is Saudi Aramco's Engineering Procedure for "Supplying Material from Stockists." It defines the 59 material numbers in Annex 4 that may be sourced from stockists rather than direct from manufacturers, and the minimum documentation each delivery must carry. Understanding these requirements is the starting point for evaluating any supplier.

59
Annex 4 Material Numbers

23 valves, 11 flanges, 13 fittings, 12 metallic pipes — the full set of 9COM stockable materials

3.1
EN 10204 MTR Minimum

Every pressure-bearing component must ship with EN 10204 3.1 material test reports traceable by heat number to the mill

CoC
Certificate of Conformance

The stockist must provide a CoC declaring that supplied materials conform to the SAEP-347 Annex 4 material number specification

QMS
Quality Management System

ISO 9001:2015 or equivalent — the stockist must maintain documented procedures for receiving inspection, storage, and traceability

Key Point for EPC Contractors

SAEP-347 does not require the stockist to be on the Aramco Approved Vendor List (AVL). The EPC contractor's own procurement and quality plan governs material acceptance. The contractor's QC inspector verifies documentation at goods receipt. A stockist's job is to have the right material, the right documentation, and deliver on time.

In Summary

Qualifying as a SAEP-347-compatible stockist involves three verifiable stages. Stage one requires ISO 9001:2015 certification with documented procedures for receiving inspection, heat-number lot control, and MTC filing, submitted alongside a formal declaration of which Annex 4 material numbers the applicant intends to stock. SAEP-347 Annex 4 contains 59 specific 9COM material numbers: 23 valve types, 11 flange types, 13 butt-weld fitting types, and 12 metallic pipe grades. Stage two is a Saudi Aramco vendor audit covering warehouse segregation by heat number, the MTC archive system, and on-demand retrieval of any stored certificate. Aramco auditors verify that the stockist maintains a minimum ten-year MTC archive and can trace each physical item to its originating mill heat. Stage three is placement on the Approved Suppliers List for the relevant 9COM numbers, subject to annual renewal. All deliveries must include the original EN 10204 3.1 MTC, a Certificate of Conformance, and a packing list cross-referencing each item to its stored certificate.

Supplier Evaluation

7-Point Checklist: How to Evaluate a SAEP-347 Stockist

Apply this checklist to any supplier who claims compatibility with SAEP-347 Annex 4 material numbers. Ask for evidence on each point before your first purchase order.

1
Saudi Commercial Registration

A Saudi-registered company (CR number, VAT number) is subject to SASO and Ministry of Commerce oversight. This matters for warranty claims, dispute resolution, and payment terms. An overseas supplier exporting to Saudi Arabia has no in-Kingdom legal accountability — disputes require international arbitration. Ask for the CR number and verify it on the Saudi Ministry of Commerce business register.

2
SAEP-347 Annex 4 Material Number Coverage

Ask the supplier for a list of which of the 59 SAEP-347 Annex 4 material numbers they regularly stock. A credible stockist will have this list ready — it is the commercial foundation of their business. Suppliers who cannot tell you which specific material numbers they hold are likely assembling stock on demand from non-compliant sources. The 59 numbers cover 23 valve types, 11 flange types, 13 fitting types, and 12 pipe grades.

3
EN 10204 3.1 Material Test Reports — On Every Delivery

This is the single most important documentation check. EN 10204 3.1 MTRs must be issued by the original manufacturer (not the stockist), must reference the heat number or lot number marked on each component, and must show chemical composition and mechanical properties test results. If a supplier cannot produce 3.1 MTRs traceable to the heat number on each item, do not purchase — no amount of price advantage compensates for a Aramco QC rejection at the site gate.

4
NACE MR0175 / ISO 15156 Sour Service Capability

A significant portion of Saudi Aramco projects involve hydrogen sulphide (H₂S) service — GOSP degassing, gas sweetening, sour crude gathering. For these applications, piping components must comply with NACE MR0175 / ISO 15156 (2015), which limits hardness of carbon steel components to ≤22 HRC (body and fittings) and ≤26 HRC (bolting). Ask the supplier whether their MTRs include hardness test data and whether they can provide NACE-compliant stock. Not all stockists maintain sour service certification.

5
ISO 9001:2015 Quality Management System

ISO 9001:2015 certification means the supplier maintains documented procedures for purchase control, receiving inspection, storage, identification and traceability, and non-conforming product control. Ask for the certificate and verify the certification body's accreditation. An ISO certificate from an unaccredited body is worthless for Aramco project documentation. Check that the certificate scope covers stockist supply of industrial piping components — not just general trading.

6
Local Saudi Stock and Confirmed Delivery Time

A supplier listing a Saudi address but shipping from an overseas warehouse is not a local stockist. Ask specifically: where is the physical stock located? What is the delivery time to your project site? Import shipments from India typically take 3–8 weeks through customs, even with air freight for small parcels. A genuine Saudi stockist with Dammam or Jubail warehouse stock delivers in 24–48 hours — that lead time difference can determine whether a turnaround stays on schedule.

7
Emergency Supply and RFQ Response Time

Unplanned plant shutdowns require material within hours, not days. Ask the supplier: can they dispatch same-day for items in stock? What is their RFQ response time? A 48-hour quotation turnaround is acceptable for routine procurement; a maintenance turnaround may need a quote in 4 hours and dispatch in 8. Test this before you need it — ask for a sample quotation on a standard item and time the response.

Supplier Comparison

Saudi Stockist vs Overseas Supplier: Procurement Comparison

The table below compares the typical capabilities of a Saudi-registered SAEP-347 stockist (such as Gulf Union Ozone) against a typical overseas supplier exporting to Saudi Arabia. All Gulf Union Ozone data is accurate as of August 2026.

Evaluation Criterion Gulf Union Ozone
(Saudi Stockist)		 Typical Overseas
(Import from India/Asia)
Saudi Commercial Registration ✅ CR 4030570569 ❌ No Saudi CR
SAEP-347 Annex 4 Coverage ✅ 59 numbers published ⚠️ Claims compliance — list rarely published
EN 10204 3.1 MTRs ✅ On every delivery ⚠️ Available on request — lead time to obtain
NACE MR0175 Sour Service ✅ Hardness-controlled stock ⚠️ Available for some items — verify per order
ISO 9001:2015 ✅ Certified ✅ Often certified (verify scope)
Physical Stock Location ✅ Jeddah + Umluj + Baish (KSA) ❌ Overseas warehouse (India / China / Europe)
Delivery Lead Time ✅ 24–48 hours to most KSA cities ❌ 3–8 weeks (customs + freight)
Emergency / Same-Day Dispatch ✅ Yes — in-stock items ⚠️ Air freight only (24–72h + customs)
RFQ Response Time ✅ 4 hours ⚠️ 24–72 hours (time zone difference)

Saudi VAT Invoice ✅ VAT 311592828300003 ❌ No Saudi VAT — customs clearance needed

When evaluating SAEP-347 stockists, EPC procurement teams compare on five structurally critical dimensions: physical stock location in Saudi Arabia (determines whether delivery is 24 hours or 3-8 weeks), published SAEP-347 Annex 4 material number list covering all 59 numbers, EN 10204 3.1 mill test certificate availability as standard on every delivery, NACE MR0175 hardness-controlled stock for H₂S sour service applications, and a Saudi CR plus VAT registration for clean in-Kingdom invoicing. A locally registered stockist holding physical Jeddah stock eliminates air freight surcharges, 3-10 day customs clearance delays, and currency risk on every order. For shutdown procurement under a 24-hour delivery constraint, overseas suppliers structurally cannot compete with an in-Kingdom stockist. Gulf Union Ozone (CR 4030570569, VAT 311592828300003) delivers to Jeddah and Western Region projects same-day, Eastern Province and Jubail within 24-48 hours, with the full EN 10204 3.1 documentation package on every SAEP-347 delivery.

Goods Receipt

Documentation Checklist: What to Demand at Goods Receipt

The EPC contractor's QC inspector must verify these documents before accepting any SAEP-347 stockist delivery. Rejecting non-conforming materials at goods receipt is far less costly than discovering them during a Aramco QC audit on site.

✓
EN 10204 3.1 Material Test Report

Issued by the manufacturer. Heat/lot number must match marking on item. Shows chemical and mechanical test results.

✓
Certificate of Conformance (CoC)

From the stockist, declaring the material conforms to the SAEP-347 Annex 4 material number specification and the applicable ASTM/ASME standard.

✓
Dimensional Inspection Report

Confirming dimensions per ASME B16.5 (flanges), B16.9 (BW fittings), or B16.34 (valves). Critical for raised-face flanges and weld end fit-up.

✓
Pressure Test Certificate (Valves)

Per API 598 (or API 6D for pipeline valves). Shell test, seat test, and backseat test results. Each valve's test date and serial number recorded.

✓
NACE Hardness Test Record (Sour Service)

Where H₂S sour service applies. Hardness readings per NACE MR0175 / ISO 15156 for body, trim, and bolting. Readings must be ≤22 HRC for carbon steel body and fittings.

✓
Packing List with Item Identification

Shows quantity, size, schedule/class, heat number, and package number. Enables cross-referencing of each physical item to its MTR and CoC.

At Saudi Aramco Goods Receipt inspection, five documents must be cross-verified before accepting any SAEP-347 stockist delivery. First: the EN 10204 3.1 Material Test Report from the original mill, with heat number matching the physical item marking and showing full chemical analysis and mechanical test results. Second: a Certificate of Conformance from the stockist referencing the SAEP-347 Annex 4 material number and the applicable ASTM or ASME standard. Third: a Dimensional Inspection Report confirming compliance per ASME B16.5, B16.9, or B16.34 as applicable. Fourth: a packing list cross-referencing each line item to its stored certificate. Fifth: for alloy and stainless steel materials, a Positive Material Identification (PMI) test record per SAEP-1142 confirming actual alloy composition. Material without a traceable MTC will be rejected at Goods Receipt and sent for third-party identity testing at the contractor's cost. Gulf Union Ozone supplies all five documents as standard on every SAEP-347 delivery.

Frequently Asked Questions — SAEP-347 Supplier Selection

What makes a supplier SAEP-347 compatible? +

A SAEP-347 compatible stockist must: (1) stock materials listed in SAEP-347 Annex 4 under specific 9COM material numbers, (2) supply EN 10204 3.1 material test reports traceable to the manufacturing heat, (3) provide a Certificate of Conformance (CoC) declaring compliance with the applicable material standard, and (4) hold a quality management system such as ISO 9001:2015. The stockist does not need to be on Saudi Aramco's Approved Vendor List (AVL) — it operates under the EPC contractor's procurement system.

How many material numbers are in SAEP-347 Annex 4? +

SAEP-347 Annex 4 contains 59 specific Aramco material numbers covering the most frequently used piping components: 23 valve material numbers, 11 flange numbers, 13 fitting numbers, and 12 metallic pipe numbers covering carbon steel, alloy steel, and stainless steel grades. See our full published list at the SAEP-347 Material Numbers page.

Does a SAEP-347 stockist need to be on the Aramco AVL? +

No. SAEP-347 is a procedure for stockist supply, not a vendor registration programme. The EPC contractor is responsible for procuring materials that conform to the applicable standards. A stockist needs an ISO 9001:2015 quality system and must keep original mill certificates traceable to each supplied item — but Aramco AVL registration is not required for a stockist operating under an EPC contractor's purchase order.

Why does local Saudi stock matter for SAEP-347 procurement? +

Saudi Aramco projects operate on tight construction and turnaround schedules. Importing from overseas suppliers typically requires 3–8 weeks including customs clearance. A Saudi-registered stockist with warehouse stock in Dammam, Jubail, or Jeddah delivers in 24–48 hours, eliminating customs delays and reducing project risk. For emergency shutdowns and maintenance turnarounds, same-day dispatch from local stock can be the difference between a scheduled and an unscheduled shutdown extension.
