Why Supply Origin Matters More Than Price for RPO, TDAE and Base Oil Buyers in 2026

The Two Straits: Why Geography Now Defines Supply Risk

There are two straits that matter for Asian petroleum supply chains. Understanding the difference between them has become commercially critical.

The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman. For decades it has served as one of the world's most important energy corridors, handling a significant share of global crude oil and petroleum product exports.

The Strait of Malacca connects the Indian Ocean to the South China Sea and runs between Malaysia, Singapore and Indonesia. It remains one of the world's busiest and most strategically important shipping routes.

For procurement teams, the lesson is straightforward: supply security is not determined solely by supplier reputation or pricing. It is also determined by geography. When major shipping corridors face disruption, supply chains become vulnerable regardless of contractual commitments.

What Has Happened to Major Supply Origins

Gulf-origin suppliers: Recent disruptions have highlighted the vulnerability of supply chains heavily dependent on Gulf-origin petroleum products. Challenges include shipping uncertainty, increased insurance costs, supply interruptions and longer procurement lead times. For buyers relying on a single origin, these disruptions have exposed significant concentration risk.

Korean-origin suppliers: South Korea remains a major producer of Group II and Group III base oils. However, export controls and domestic supply prioritisation have periodically tightened availability into Southeast Asia and South Asia. For lubricant blenders and distributors, this has reinforced the importance of maintaining alternative sourcing options.

Indian-origin suppliers: India continues to play a major role in supplying process oils and base oils into regional markets. However, rising feedstock costs and changing crude supply dynamics have affected pricing competitiveness across several product categories. For price-sensitive buyers, landed cost advantages have narrowed considerably.

Malaysia-origin supply: Malaysia remains strategically positioned along the Strait of Malacca and continues to offer reliable export connectivity into Southeast Asia and South Asia.

• Established refining infrastructure
• Strong regional logistics connectivity
• Access to ASEAN markets
• Multiple export routes through major ports

Malaysia-Origin Alternatives Available

Malaysia remains capable of supplying a broad range of industrial petroleum products. Availability, lead times and pricing vary by grade and volume, but the key takeaway remains the same: supply continuity has become just as important as price competitiveness.

• Aromatic Rubber Process Oils (RPO)
• Treated Distillate Aromatic Extract (TDAE)
• Group I Base Oils
• Group II Base Oils
• Naphthenic Base Oils
• White Oils

Why TDAE Demand Continues to Increase

While conventional aromatic RPO remains widely used across Asia, TDAE continues to gain importance among tyre manufacturers serving export markets. The primary driver is not simply regulation — it is customer requirements.

Many tyre manufacturers supplying Europe and developed markets are increasingly evaluating lower-PAH process oils to support product compliance requirements and evolving tyre formulations. As a result, procurement teams are balancing three critical considerations: supply continuity, cost competitiveness and product compliance.

In many applications, TDAE is no longer viewed as a niche alternative. It is becoming a strategic procurement category.

Why Base Oil Buyers Should Pay Attention

Group I, Group II and Group III base oil markets are facing many of the same supply chain pressures affecting process oils. Historically, buyers across Southeast Asia relied heavily on supply originating from a limited number of producing regions. Recent disruptions have highlighted the risks of concentrating procurement within a small number of supply origins.

For lubricant blenders, distributors and industrial users, the challenge is no longer limited to obtaining competitive pricing. The challenge is ensuring continuity of supply for key grades such as SN150, SN500, 150N, 500N and Group III grades.

As market conditions evolve, procurement teams are increasingly evaluating alternative supply origins that offer both logistical reliability and consistent export availability.

A Simple Supply Risk Assessment Framework

When evaluating suppliers in the current environment, procurement teams should assess more than price. Price remains important — however, supply interruptions often cost significantly more than a modest difference in purchase price.

• Origin risk — can the supplier continue shipping if market conditions worsen?
• Logistics risk — are freight routes stable and operational?
• Supply flexibility — can the supplier support required packaging and shipment options?
• Regulatory compliance — is the product suitable for current and future customer requirements?
• Inventory position — does the supplier have reliable production and storage capability?

A Note on ATIGA and Import Duty

Procurement teams in Vietnam and Indonesia should also evaluate the potential benefits available under the ASEAN Trade in Goods Agreement (ATIGA). Malaysian-origin aromatic RPO may qualify for preferential duty treatment when supported by the appropriate Certificate of Origin documentation.

For buyers within ASEAN markets, this can create meaningful landed cost advantages compared to non-ASEAN supply origins. Import regulations vary by product classification and destination country, and buyers should verify current requirements before shipment.

What Procurement Teams Should Be Doing Right Now

The companies navigating today's market most effectively are not necessarily those buying at the lowest price. They are the ones managing supply risk correctly.

The biggest mistake in today's market is assuming supply disruptions will be resolved as quickly as financial markets react.

• Review country-of-origin exposure across all petroleum and process oil purchases.
• Confirm alternative supply origins outside existing sourcing regions.
• Secure sufficient inventory coverage where possible.
• Evaluate regional sourcing options and applicable trade benefits.
• Maintain active communication with logistics providers regarding freight availability and lead times.

Final Thoughts

The current market environment has reminded procurement teams of a reality often overlooked during stable periods: supply origin matters.

For buyers across Vietnam, Bangladesh, Indonesia and India, procurement decisions can no longer be based solely on price. Reliability of origin, freight accessibility and supply continuity have become equally important considerations. Companies that diversify supply sources early are generally better positioned than those relying on a single origin or shipping corridor.

Frequently asked questions

Why does supply origin matter more than price for RPO, TDAE and base oil in 2026?

Recent disruptions across Middle East shipping corridors have shown that contractual commitments do not guarantee delivery if the cargo cannot transit. A small price advantage is quickly erased by a single missed shipment, idle blending plant or stalled tyre line. Origin determines whether supply can actually reach the buyer.

Why is Malaysia a strategic alternative supply origin for Asian buyers?

Malaysia sits on the Strait of Malacca with established refining and petrochemical infrastructure, multiple export ports and strong logistics connectivity across ASEAN and South Asia. It provides a credible diversification option for buyers reducing concentration on Gulf, Korean or Indian origins.

Can Malaysian-origin aromatic RPO qualify for ATIGA preferential duty?

Malaysian-origin aromatic RPO may qualify for preferential duty treatment under the ASEAN Trade in Goods Agreement when supported by the appropriate Certificate of Origin. Buyers in Vietnam and Indonesia should confirm tariff classification and documentation requirements with their import broker before shipment.

Which base oil grades are most exposed to supply origin risk?

Group II and Group III grades such as SN150, SN500, 150N and 500N are concentrated in a small number of producing regions, which makes them the most exposed to origin risk. Procurement teams should secure alternative supply origins for these grades before shortage windows.

Does Sanyang Petroleum supply RPO, TDAE and base oils from Malaysia?

Yes. Sanyang Petroleum is a Malaysia-based supplier and trader of aromatic RPO, TDAE, Group I and Group II base oils, naphthenic base oils and white oils, serving lubricant blenders, rubber compounders and industrial buyers across Asia-Pacific.
