ExxonMobil's Asia Pacific headquarters sits in Singapore. That's not a regional sales office — it's the operational center for one of the world's largest integrated refining and petrochemical complexes, spread across Jurong Island. The site produces fuels, lubricants, and specialty chemicals for markets across Asia. That scale drives serious procurement activity, and a meaningful share of it flows to Singapore-based suppliers.
This guide covers how to get registered, what categories they buy, and how WEConnect International certification fits into the picture.
What ExxonMobil buys in Singapore and APAC
The Jurong Island complex is ExxonMobil's largest integrated manufacturing site outside the United States. It includes refineries, chemical plants, and specialty product facilities operating around the clock. Keeping that infrastructure running requires continuous procurement across several categories:
- Engineering and technical services: Inspection, mechanical, instrumentation, and civil engineering work tied to planned and unplanned maintenance turnarounds
- Maintenance, repair, and operations (MRO): Spare parts, tools, safety equipment, consumables
- IT and digital services: Software, infrastructure support, cybersecurity, data analytics
- Logistics and transportation: Intra-island materials movement, port logistics, customs brokerage
- Professional services: Legal, finance, HR, training, environmental consulting
- Chemicals and industrial supplies: Feedstocks, specialty chemicals, lab reagents
The engineering and maintenance category is the highest-volume local procurement category. Singapore-based contractors with valid WSH (Workplace Safety and Health) certification and relevant technical credentials have the clearest path to active contracts.
ExxonMobil's supplier diversity commitment
ExxonMobil is a founding corporate member of WEConnect International, the organization that certifies women-owned businesses for corporate supplier diversity programs globally. That founding membership is meaningful. It means ExxonMobil helped shape the WEConnect certification standard and has committed at the senior procurement level to including WEConnect-certified suppliers in their sourcing pipeline.
ExxonMobil's supplier diversity program is managed through their Global Procurement organization. In the APAC region, supplier diversity efforts are coordinated through the Singapore procurement team alongside the global program structure. The company's stated goal is to provide opportunities to businesses owned by women, minorities, veterans, people with disabilities, and LGBTQ+ individuals where local regulations and company policy permit.
Singapore's legal environment is different from the United States. There is no equivalent of the U.S. federal set-aside framework, and ExxonMobil cannot mandate percentage targets for diverse spend in Singapore the way U.S. corporations sometimes do domestically. What they can do, and do do, is track diverse supplier spend, include WEConnect-certified and other diverse suppliers in RFQ processes, and give procurement managers goals for diverse supplier engagement.
How to register: the Ariba Supplier Network
ExxonMobil uses SAP Ariba as its procurement platform globally. To become a registered ExxonMobil supplier, you need to be in their Ariba system.
The starting point is the ExxonMobil Supplier Registration Portal, accessible through the SAP Ariba Supplier Network (ariba.com). If ExxonMobil initiates contact with you after an RFQ or introduction, they will send you a specific registration invitation. If you're approaching them proactively, you register on the SAP Ariba Network as a supplier, then indicate your interest in ExxonMobil as a buying organization.
Registration requires: - Company legal name and registration number (for Singapore companies, your ACRA-registered UEN) - Business address and contact details - Primary NAICS or UNSPSC commodity codes for your services or products - Tax identification information - Banking details for payment setup (required for active supplier status) - Certificates: relevant industry licenses, ISO certifications if applicable, WSH certification for on-site contractors
The registration itself takes 30 to 60 minutes if you have all documents ready. Ariba network accounts are free at the basic tier. Once registered, your profile sits in ExxonMobil's supplier database, but registration alone does not guarantee you get contacted for bids.
WEConnect International certification and ExxonMobil specifically
WEConnect International certifies businesses that are at least 51% owned, managed, and controlled by one or more women. In Singapore, WEConnect's Asia Pacific team handles certification. The process involves a document review, business verification, and an annual renewal fee (approximately USD 350 for companies under USD 1 million in revenue, scaling up for larger businesses).
Because ExxonMobil is a WEConnect founding member, WEConnect-certified suppliers gain a direct channel that most suppliers don't have. WEConnect runs supplier-buyer matchmaking events in Singapore and across APAC — ExxonMobil procurement staff regularly attend these. A WEConnect certification also signals to ExxonMobil's procurement system that your company has been vetted under a recognized third-party standard.
Practically, this matters most at the shortlisting stage. When an ExxonMobil category manager is building a bid list for an engineering services contract, having a WEConnect certification moves you from "unknown vendor" to "diverse supplier with verified credentials." That doesn't guarantee selection, but it removes a friction point.
If you are a women-owned business, pursuing WEConnect certification before approaching ExxonMobil is the highest-leverage first step. If you're not women-owned, focus on the Ariba registration and direct outreach to procurement contacts through LinkedIn or industry events.
Singapore-specific considerations
Singapore suppliers need several baseline credentials before ExxonMobil's procurement team will seriously evaluate them for Jurong Island work:
bizSAFE Level 3 or higher: Required for contractors performing on-site work at petrochemical facilities. Managed through the Singapore Workplace Safety and Health Council. Level 3 takes approximately three to four months to complete if you don't already hold it.
ISO 9001 certification: Not always mandatory, but expected for technical service providers. Several Singapore-based certification bodies (Bureau Veritas, SGS, TÜV SÜD) offer ISO 9001 audits, typically taking two to three months from initial assessment to certification.
ACRA registration with relevant SSIC codes: Your Singapore Standard Industrial Classification code should match the services you're offering. This comes up in Ariba commodity code matching.
Goods and Services Tax (GST) registration: If your annual turnover exceeds SGD 1 million, you are legally required to be GST-registered. ExxonMobil will verify this during supplier onboarding.
Companies without these credentials in place should plan for a three to six month preparation window before active supplier outreach.
Practical first steps and realistic timeline
Here is what a credible path to a first purchase order looks like, assuming you're starting from a qualified baseline:
Month 1: - Confirm all Singapore regulatory credentials are current (bizSAFE, ACRA, GST) - Register on the SAP Ariba Network and complete your supplier profile fully - Apply for WEConnect International certification if you qualify (women-owned)
Month 2–3: - Attend at least one WEConnect APAC event where ExxonMobil procurement staff are present — check WEConnect's Singapore event calendar - Identify the specific ExxonMobil category your services map to (engineering, IT, logistics, etc.) and research recent public procurement notices or news about Jurong Island expansion projects - Connect with ExxonMobil procurement contacts on LinkedIn; reference your Ariba registration in any outreach
Month 4–6: - Follow up with ExxonMobil procurement contacts after events; request a capabilities presentation call - Prepare a capabilities brief: one to two pages covering your technical scope, key personnel credentials, safety record (TRIR if applicable), reference clients in the petrochemical or heavy industry sector - If you receive an RFI or RFQ, treat response time as a credibility signal. ExxonMobil procurement teams track which suppliers respond promptly and completely
Month 6–18: - Realistically, first purchase orders for new suppliers are small-scope or spot contracts: a specific inspection task, a short-duration IT project, a one-time logistics coordination assignment. These are how ExxonMobil vets new suppliers before awarding standing contracts - Performance on a small first contract is the fastest path to inclusion in the next competitive bid for larger scope work
The full cycle from initial registration to a standing maintenance contract is typically 12 to 24 months for companies without prior relationships at the site. Spot contracts can come faster, sometimes within six months of registration, if your capabilities match an active need.
What to avoid
Do not submit generic brochures. ExxonMobil's procurement team at Jurong Island deals with specialized technical requirements; a generic marketing document signals you don't understand their operating environment.
Do not approach without safety credentials if you're offering on-site services. Petrochemical facilities operate under strict contractor management systems, and a supplier without visible WSH credentials will not advance past initial screening.
Do not register and wait. Ariba registration is passive. The suppliers who win contracts combine a complete Ariba profile with active relationship-building through industry events, WEConnect connections, or direct outreach.
The honest bottom line
Getting onto ExxonMobil's supplier list in Singapore is achievable for qualified local businesses. The Jurong Island complex is large enough that procurement happens continuously, not in one annual cycle. The WEConnect founding membership gives women-owned businesses a genuine edge, not just a checkbox. And the Ariba registration process is straightforward compared to many large corporate portals.
The path is slow if you're waiting for ExxonMobil to find you. It moves faster when you show up where their procurement staff are, with credentials that match what they need on Jurong Island.
