Used cooking oil from Vietnam: collection, semi-processing and export checks

A small, export-oriented collection chain

Vietnam is not a volume player in used cooking oil in the way China or Malaysia are, and that matters when you set procurement expectations. According to USDA’s 2026 Vietnam Biofuels report, UCO collection in the country is low. Local industry describes small-scale collection—often from restaurants, street-food vendors and canteens—followed by semi-processing before export.

That structure produces irregular monthly volumes. One processor may load two flexitanks this month and nothing next month because collection did not keep pace. A buyer should therefore ask whether an offer comes from the processor’s own collection network or from oil purchased on the open market, and how many distinct sources feed the lot you are being asked to buy.

Geography adds another layer. Collection tends to cluster around major cities where food service is dense; rural oil is harder to aggregate economically. If a seller quotes large, perfectly steady volumes without explaining how they collect, treat that as a qualification issue, not a pricing opportunity.

What semi-processing actually does—and does not do

In Vietnam, “semi-processing” usually means settling, filtering, maybe heating and skimming, and storing until there is enough tonnage to fill an export container. It can materially improve moisture and impurities on a certificate of analysis, which helps the cargo meet a refinery’s basic intake spec.

It does not, by itself, prove that the oil is genuinely used cooking oil from the declared points of origin. Semi-processing is a handling step, not a traceability system. Request a written description of the process: equipment, batch sizes, how long oil sits before export, and whether different collectors’ oil is co-mingled in the same tank.

Ask for collection records that tie the export lot to dated receipts from named food businesses or collectors. For EU biofuel buyers, the collecting point or aggregator will typically need ISCC EU certification and self-declarations from its sources; verify any certificate in the ISCC certificate database rather than trusting a PDF alone.

Policy: SAF ambitions and waste law

Vietnam’s government is thinking ahead about sustainable aviation fuel even though production has not started. In August 2025 the Ministry of Industry and Trade issued Directive 13 on SAF development, which lists UCO among domestic feedstocks to assess. The directive is a planning signal: UCO is on the policy map, not yet locked into a mandate or a domestic offtake programme.

Today, export remains the main commercial outlet because Vietnam does not produce SAF yet. That could change over the next few years if domestic projects move from assessment to investment. Long-term buyers should watch whether collection networks sign exclusive deals with future SAF or biodiesel plants.

The revised Law on Environmental Protection (2020) provides the framework for waste management, including used cooking oil as a waste stream that must be handled by licensed operators. Ask exporters for their environmental and waste-handling permits, and check that transport from collector to processor is covered. A missing waste licence is not something you can fix at the loading port.

Destination rules: EU, aviation and the United States

Most Vietnamese UCO that leaves the country still heads toward EU and Asian renewable fuel buyers, who will ask for a full evidence file: lot-specific certificate of analysis, independent inspection at loading, sustainability declarations where applicable, and Union Database entries for EU RED markets.

From 19 November 2027, Regulation (EU) 2025/2181 adds animal-health import conditions for UCO: each consignment must originate from an approved or registered establishment in Vietnam, be filtered or separated to at most 10% combined moisture and solids before shipment, travel with the model importer declaration, and move under official monitoring to an eligible EU receiving plant. A small semi-processor may not have started the approval process; check early if your contract runs past that date.

For aviation fuel chains, buyers may require ISCC CORSIA evidence in addition to ISCC EU. US buyers should note separately that fuel produced after 31 December 2025 no longer earns the 45Z credit when the feedstock comes from outside the United States, Canada or Mexico—Vietnamese UCO is not a shortcut to US tax credits regardless of quality.

What to verify before you contract

Treat Vietnamese UCO like any origin where the collection base is fragmented: spend time on documents before you argue about price. Confirm the processor’s business registration, export experience and waste permits, then walk the chain from collection receipt to the tank that will feed the flexitank or bulk parcel.

Appoint an independent inspector at loading, or agree jointly on one, and tie the certificate of analysis to the inspected tank and seal numbers. Payment should follow documentary security—a letter of credit or equivalent—not a large prepayment against scanned papers. Trade associations have warned repeatedly about forged bills of lading and certificates in the wider UCO market; Vietnam’s smaller players are not exempt from that risk.

If you need recurring supply, build redundancy. Two qualified processors with overlapping collection zones beat a single “exclusive” seller who may miss a month without warning.

• Processor licence and environmental permits
• Description of the semi-processing step
• Collection records and number of sources per lot
• Independent inspection and COA at loading
• ISCC certificate where the buyer requires it
• EU establishment approval or registration for cargoes from November 2027

Logistics and how deals are usually structured

Export volumes from Vietnam typically move in flexitanks inside 20-foot containers rather than in large bulk tankers. That suits smaller lots but adds handling steps: iso tank preparation, heating if needed, and port storage while documentation clears. Fix the Incoterm, the loading inspection and who pays for demurrage before you book freight.

Contracts often run on a shipment-by-shipment basis with an option to repeat, rather than on a fixed monthly programme, because collection is uneven. Build lead time for permit checks, tank preparation and laboratory results; rushing a load tends to produce gaps in the file that an EU or SAF buyer will reject at destination.

Turco & Co reviews documented UCO offers from Vietnam when sellers can provide collection records, lot analyses and permit status. That review is qualification work, not a substitute for your own inspection and certificate checks.
