Used Cooking Oil Price Trend in Vietnam: Q3 2026 Prices, Market Forecast, Price Chart and Index

The Used Cooking Oil Price Trend in Vietnam moved downward during the third quarter of 2026, with export prices falling by around 11% compared with the previous quarter. The decline was mainly driven by reduced buying activity after the strong gains recorded earlier, as buyers became more cautious and prices corrected from their previous high levels. Comfortable regional supply also added pressure to the market, allowing export prices on a Free on Board (FOB) Haiphong basis to ease during the quarter. However, the market showed signs of recovery in September, when Used Cooking Oil Prices in Vietnam increased by nearly 3% as biodiesel producers returned to the market to purchase feedstock. This late-quarter improvement indicated that buying interest was gradually strengthening again.

Used cooking oil, commonly known as UCO, is a valuable recycled material collected from restaurants, food processing facilities, commercial kitchens, and other sources. Instead of being discarded after use, it can be processed and converted into feedstock for biodiesel and other industrial applications. Its value depends on several factors, including collection volumes, quality, processing requirements, export demand, and competition from alternative feedstocks.

Vietnam participates in the international used cooking oil trade, and export prices can change as overseas buyers adjust their purchasing plans. For exporters, collectors, biodiesel producers, and traders, understanding these movements is important for planning inventory, negotiating contracts, and managing business costs.

This article explains the Used Cooking Oil Price Trend in Vietnam during Q3 2026, the reasons behind the quarterly decline, the September recovery, and the possible direction of prices in the coming months.

Used Cooking Oil Price Trend in Vietnam During Q3 2026

The Vietnamese used cooking oil market experienced a clear correction during the third quarter of 2026. Export prices for material with a free fatty acid (FFA) level of 5%, assessed on an FOB Haiphong basis, declined by approximately 11% compared with the previous quarter.

FOB, or Free on Board, is a shipping term that generally means the seller's responsibility for delivery costs ends when the goods are loaded onto the vessel at the agreed port. The buyer usually takes responsibility for the main sea freight and subsequent costs. This makes FOB pricing useful for evaluating the export market before overseas shipping expenses are added.

The decline during Q3 followed stronger prices in the previous quarter. After prices reached elevated levels, some buyers reduced procurement and became more selective about new orders. This reduced immediate demand and placed pressure on export valuations.

Regional supply conditions also contributed to the downturn. When sufficient material is available from collectors and suppliers, buyers have less reason to compete aggressively for shipments. Suppliers may then need to adjust their offers to attract purchasing interest.

Despite the overall quarterly decline, September brought a positive change. Used cooking oil prices increased by nearly 3% during the month as biodiesel producers returned to the market for feedstock. Collectors also maintained firmer offers, helping support the recovery.

The combination of a substantial quarterly decline and a modest September increase shows that the market was moving through two different phases: an earlier correction followed by a late-quarter improvement.

Key Factors Influencing Used Cooking Oil Prices in Vietnam

1. Reduced Buying Activity After Earlier Price Gains

One of the main reasons behind the Q3 2026 decline was the reduction in purchasing activity after the gains recorded in the previous quarter.

When a commodity becomes more expensive over a short period, buyers may decide to delay purchases rather than accept higher prices immediately. They may use existing inventory, negotiate with suppliers, or wait for the market to become more affordable.

This type of behavior is common in commodity markets. Buyers do not always increase their purchases simply because a product is available. They also consider current prices, expected future costs, and the amount of material they already hold.

In Vietnam, cautious procurement contributed to the decline in used cooking oil export prices during Q3 2026. As purchasing interest weakened, sellers faced greater pressure to offer competitive prices.

For collectors and exporters, this situation can make inventory planning more difficult. Holding too much material during a period of weak demand can increase storage and handling expenses, while selling too quickly may reduce potential returns if prices later recover.

2. Comfortable Regional Supply

Supply availability was another important factor affecting the Used Cooking Oil Price Trend in Vietnam.

Used cooking oil comes from many sources, including restaurants, hotels, food manufacturers, and commercial kitchens. The amount collected can change according to consumption patterns, collection networks, and local operating conditions.

When regional supply is comfortable, buyers have more options when negotiating prices. They can compare different offers and avoid paying higher prices simply to secure immediate availability.

During Q3 2026, sufficient regional supply added pressure to export valuations. With buyers becoming more cautious at the same time, the market faced pressure from both sides.

This combination helps explain why FOB Haiphong prices eased through the quarter.

However, available supply does not always mean that every shipment is equally suitable for every buyer. Moisture content, impurities, FFA levels, and other quality requirements can influence whether material meets a particular buyer's specifications.

For this reason, exporters should focus on both competitive pricing and consistent product quality.

3. Demand from Biodiesel Producers

Biodiesel production is an important source of demand for used cooking oil. UCO can be processed into feedstock for biofuel production, depending on its quality and the processing technology used.

Biodiesel producers evaluate several factors before purchasing feedstock. These include the price of used cooking oil, the availability of alternative raw materials, processing expenses, product specifications, and expected returns from finished fuel.

When feedstock costs are high, producers may reduce purchases or delay new orders. When prices become more attractive, they may return to the market to secure material for future production.

This pattern was visible in Vietnam during Q3 2026. Buyers reduced procurement after earlier price gains, but biodiesel producers returned to the market in September.

Their renewed buying interest contributed to the nearly 3% monthly price increase and improved market sentiment toward the end of the quarter.

Future demand from biodiesel producers will remain an important factor to watch when evaluating Used Cooking Oil Prices.

4. Collector Offers and Procurement Costs

Collectors play an important role in the used cooking oil supply chain. They gather material from food businesses and other collection points before it is sold to processors, traders, or exporters.

Their offers depend on collection costs, handling expenses, material quality, local competition, and the prices available in the export market.

When export prices fall, collectors may face pressure to lower their selling offers. However, they may not always adjust prices immediately, especially if their own collection and operating expenses remain unchanged.

In September 2026, collectors held their offers firmer as buyers returned to the market. This helped support the price recovery.

The relationship between collectors and exporters is important because the export price must account for costs across the supply chain. A change in overseas demand can therefore influence purchasing decisions at earlier stages of collection.

5. Product Quality and FFA Levels

Quality is an important consideration when comparing used cooking oil prices. The market assessment discussed here covers material with an FFA level of 5%.

FFA stands for free fatty acids, which are naturally present in oils and fats and can increase during use, storage, or handling. The FFA level is one of the specifications buyers may use when evaluating UCO for industrial processing.

Different buyers may have different quality requirements depending on their processing equipment and intended use. Other characteristics, such as moisture, impurities, and consistency, can also affect the suitability of a shipment.

This means that two offers for used cooking oil may not be directly comparable if the material has different specifications.

For exporters and traders, maintaining clear quality documentation and consistent handling practices can help build buyer confidence and reduce disagreements during shipment inspections.

Monthly Market Review: July, August and September 2026

July 2026: The Market Faced Downward Pressure

July formed part of a quarter in which used cooking oil export prices moved lower after the earlier gains.

Buyers became more cautious about procurement, while comfortable regional supply reduced the urgency to secure additional material. This combination contributed to weaker market sentiment.

For exporters, the main challenge during such a period is balancing inventory levels with the risk of further price declines. Buyers, meanwhile, may prefer smaller purchases until they gain a clearer understanding of market direction.

The available data does not provide an exact July price or a separate monthly percentage change, so a specific numerical movement cannot be assigned to the month.

August 2026: Cautious Buying Continued

August remained within the broader downward market trend described for Q3 2026.

After prices had risen in the previous quarter, buyers continued to adjust their purchasing plans. With regional supply readily available, they had more flexibility to negotiate offers and manage their inventory.

When demand slows while supply remains comfortable, sellers may find it more difficult to maintain earlier price levels.

This type of market environment can encourage traders to review stock levels, shipment schedules, and customer commitments more carefully.

Although the overall quarter recorded an 11% decline, the exact monthly movement for August was not provided in the available information.

September 2026: Prices Recovered by Nearly 3%

September brought a change in market direction. Used cooking oil export prices in Vietnam increased by nearly 3% compared with August as biodiesel producers returned to the market to purchase feedstock.

The renewed buying interest helped improve market sentiment. Collectors also maintained firmer offers, providing additional support to export valuations.

This recovery suggests that lower prices may have encouraged some buyers to return after reducing their procurement earlier in the quarter.

However, the monthly increase should not be interpreted as a complete reversal of the quarterly decline. An 11% decrease across the quarter and a nearly 3% increase in September measure different movements and periods.

The September recovery indicates that downward pressure had eased, but further market direction would depend on the strength of feedstock demand and the availability of supply.

Used Cooking Oil Price Chart: Q3 2026 Market Overview

A Used Cooking Oil Price Chart helps exporters, traders, and biodiesel producers understand the market's direction across different periods.

Based on the available information, the Q3 2026 trend can be summarized as follows.

The table shows the reported market direction rather than exact prices. Since monthly FOB Haiphong prices in USD per metric ton were not provided, it would be misleading to invent numerical values for a price chart.

For a more detailed chart, businesses could track monthly FOB Haiphong export prices for UCO with an FFA level of 5%. It would also be useful to monitor collection volumes, export shipment data, supplier offers, and demand from biodiesel producers.

Using consistent product specifications and pricing terms would make it easier to identify genuine market changes and compare prices across quarters.

Understanding the Used Cooking Oil Price Index

The Used Cooking Oil Price Index is a way to measure price changes over time against a selected reference period. It can help businesses understand whether prices are rising, falling, or remaining stable without focusing only on individual quotations.

For example, if the Q2 2026 average price index is set at 100, an 11% decline would correspond to an illustrative Q3 index of 89, assuming the same product specifications, pricing basis, and averaging method are used.

This is an illustrative calculation based on the reported quarterly percentage change, not an independently published market index.

The September increase of nearly 3% should be considered separately. A monthly price movement compares September with August, while the quarterly average compares Q3 with Q2. The two measures can show different directions at the same time.

A reliable Used Cooking Oil Price Index should use consistent product quality, a clearly defined pricing basis, and a transparent calculation method.

For the Vietnamese market, tracking material with an FFA level of 5% on an FOB Haiphong basis would provide a consistent reference for exporters and buyers.

Used Cooking Oil Price Forecast for Vietnam

The Used Cooking Oil Price Forecast for Vietnam will depend on feedstock demand, regional supply availability, collector offers, and purchasing decisions by biodiesel producers.

The 11% quarterly decline suggests that the market experienced a significant correction during Q3 2026. However, the nearly 3% increase in September indicates that buying interest began to recover toward the end of the quarter.

If biodiesel producers continue returning to the market and purchasing activity strengthens, prices may receive further support. Firmer collector offers could also contribute to higher export valuations.

On the other hand, if buyers reduce procurement again or regional supply remains comfortable, prices may face renewed downward pressure.

Three possible scenarios are worth considering:

• Stable-price scenario: Biodiesel demand remains consistent and supply is sufficient to meet requirements. Prices may move within a relatively narrow range.
• Upward-price scenario: Feedstock demand strengthens, buyers compete for suitable material, and collectors maintain firmer offers. Export prices may increase.
• Downward-price scenario: Buyers delay procurement, supply remains comfortable, and sellers compete more actively for orders. Prices may face additional pressure.

These are possible scenarios rather than confirmed predictions. The available Q3 2026 information does not establish an exact future price or percentage change.

Businesses should monitor export quotations, biodiesel purchasing activity, regional supply, and quality specifications before making major procurement decisions.

Practical Tips for UCO Collectors, Exporters, and Buyers

Businesses involved in the used cooking oil market can take several practical steps to manage price changes.

Monitor buyer demand regularly. Changes in biodiesel producers' purchasing activity can influence export prices. Regular communication with customers can help suppliers understand current requirements.

Manage inventory carefully. Holding large quantities during a falling market can expose sellers to lower future prices. Inventory planning should reflect collection volumes, storage capacity, and confirmed customer demand.

Maintain consistent product quality. Clear documentation of FFA levels, moisture, impurities, and other relevant specifications can help avoid disputes and improve buyer confidence.

Compare export offers on the same basis. Make sure quotations use comparable FOB terms, quality specifications, and shipment conditions before evaluating price differences.

Watch monthly and quarterly trends together. The 11% quarterly decline and nearly 3% September recovery show why both longer-term movements and recent changes matter.

Build reliable supply relationships. Consistent collection networks and communication with buyers can help businesses respond more effectively when market conditions change.

Conclusion

The Used Cooking Oil Price Trend in Vietnam experienced a significant downward movement during Q3 2026, with export prices falling by around 11% compared with the previous quarter. Reduced procurement after earlier price gains and comfortable regional supply contributed to the decline, while cautious buying kept FOB Haiphong export valuations under pressure.

September brought a modest recovery, with prices increasing by nearly 3% as biodiesel producers returned to the market for feedstock and collectors maintained firmer offers. This improvement showed that demand was beginning to strengthen, although it did not establish a complete reversal of the quarterly decline.

Looking ahead, Used Cooking Oil Prices in Vietnam will depend on biodiesel demand, collection volumes, product quality, and the balance between regional supply and buyer requirements. A consistent Used Cooking Oil Price Chart and a clearly defined Used Cooking Oil Price Index can help businesses follow these developments and compare market movements over time.
