UCO feedstock for HVO renewable diesel producers
HVO is renewable diesel made by hydrotreating fats and oils. Used cooking oil sits alongside tallow, palm fatty acid distillate, and other waste lipids as a feedstock European and Asian refineries run every day. On the desk, HVO enquiries sound like biodiesel enquiries until you read the spec sheet: the same tank of UCO can be on offer for UCOME and for HVO, but the refinery questions are not interchangeable. Price matters, yet a parcel that wins on cents per tonne can still fail on phosphorus, on a gap in the Union Database, or on a delivery date that misses the pretreatment campaign. Buyers also distinguish material that will enter a standalone HVO train from oil destined for co-processing at a conventional refinery—pretreatment capacity and scheme rules differ. This page walks through how HVO plants read UCO, what documents must travel with the cargo, and what to send when you need feedstock for a hydrotreater rather than an esterification line.
HVO is not biodiesel (FAME)
Biodiesel, including UCOME from used cooking oil, is produced by transesterification. The product remains a fatty-acid ester with oxygen in the molecule, and fuel standards treat FAME as a blending component with its own storage and stability habits. HVO is produced by hydrotreating: hydrogen reacts with the triglycerides and free fatty acids, oxygen leaves as water, and the refinery obtains paraffinic hydrocarbons in the gasoil range—marketed as renewable diesel or co-processed renewable diesel depending on the site and the jurisdiction. Coproducts can include renewable naphtha, LPG, and off-gas used in the hydrogen plant; economics follow gasoil spreads as much as feedstock cost. Because the chemistry differs, a buyer asking for “UCO for biofuels” might mean two incompatible processes. UCOME plants worry about FFA, water, and soap formation in the reactor; HVO units worry about catalyst life and metallo-organic poisons after pretreatment. You may see the same origin offered into both markets in the same week; each offer should cite the spec that plant sent, not a generic “max FFA 5%” line copied from a biodiesel template.
What an HVO refinery checks in UCO
Laboratory panels for HVO feedstock start where most UCO trades start: free fatty acids, moisture, impurities and volatiles (MIU), sulphur, and often iodine value as a hint on double bonds and oxidative history. HVO buyers then add limits that reflect their pretreatment and hydrotreating catalyst sensitivity. Phosphorus—from lecithin in vegetable oils—is a common reject reason when pretreatment cannot strip it reliably. Metals such as iron, copper, and nickel trace back to fryers, utensils, or storage; sodium and potassium can appear from cleaning chemicals. Chlorine and nitrogen may be capped when the refinery tracks catalyst deactivation. Some units screen for polyethylene or packaging fragments after incidents with solid carry-over. Winterised or long-haul parcels may specify cloud point or filtration time. None of these numbers are universal: Neste, TotalEnergies, Eni, and standalone pretreatment-plus-HVO projects each publish different maxima. The trading conversation is therefore a line-by-line comparison between your certificate of analysis and their issued specification, not a debate about whether “export grade UCO” exists as a single grade.
Pretreatment and why one CoA does not fit every plant
Before UCO touches the hydrotreater, it passes through degumming, deacidification, filtration, adsorption, or a combination tailored to the feed. A refinery with deep pretreatment can occasionally accept a slightly dirtier truck load because its front end is sized for it; a unit that feeds relatively clean oil straight to the reactor will reject the same analysis. That is why two HVO buyers respond differently to identical lab results. Aggregators blend streams to hit FFA targets; blending can dilute a contaminant or hide a spike that still fails on a strict phosphorus cap. If you collect from many small generators, ask how homogenisation works, whether tanks are nitrogen-blanketed, and whether retention samples represent the export parcel. For spot cargoes, refineries sometimes request a pre-shipment sample sent to their lab or a trial drum before they repeat the origin. Flexitank loadings need attention to heating pads, filter socks, and line flushing—water picked up at loading shows up in MIU and can upset pretreatment balances. Traders who only rerun FFA after a long storage stay can get surprised at discharge. When we match supply to an HVO requirement, we treat pretreatment fit as seriously as the headline FFA.
Evidence that follows the oil
European HVO sold with Renewable Energy Directive credit needs proof that the feedstock qualifies as waste and that mass balance is intact. In practice, many producers work through ISCC EU: collecting points, aggregators, traders, and the refinery each hold scopes that must chain without breaks. The Union Database for Biofuels (UDB) increasingly carries the transactional record auditors expect. Regulation (EU) 2025/2181 adds another layer for imports: from 19 November 2027, UCO imported into the EU must come from an approved or registered establishment in the country of origin and move to an approved plant. Exporters who only held informal self-declarations from restaurants need to plan registration timelines now, not when a vessel is already fixed. Outside the EU, buyers may rely on ISCC PLUS, national schemes, or internal due diligence. Turco & Co trades documented lots; we are a Sharjah-licensed trading house, not a substitute for a refinery’s certification audit. Your file should show origin, collection dates, aggregation steps, transport, and the sustainability declaration that matches the shipment quantity. A quality CoA without chain-of-custody does not unlock RED value, no matter how good the FFA looks on paper.
Delivery basis, packaging, and timing
HVO refineries buy on the same commercial bases as other bulk oils, but operational reality favours predictable arrivals. CIF ARA remains the reference language for northwest European units comparing offers against published CIF ARA assessments from price reporting agencies such as Fastmarkets or Quantum Commodity Intelligence—always as benchmarks, not as a substitute for quoting your lot. FOB origin suits export tank farms in Malaysia, China, or the Americas when the refinery charters freight. DAP or delivered-to-plant terms appear when the seller or trader manages inland legs into pretreatment. Flexitanks in twenty-foot containers dominate containerised UCO; larger HVO sites may prefer bulk vessel parcels with heating capability. Demurrage and laytime bite when a refinery slot is missed, so contracts spell out notice periods, acceptable ports, and whether discharge samples govern final quality. Seasonality matters: cold ports raise viscosity and pumping issues; summer can increase FFA if storage is warm. When you request supply, state incoterms, port or plant, packing, laycan, and whether the buyer’s surveyor must attend loading—we use that to filter origins that cannot execute on those terms.
Requesting UCO for an HVO unit
Send the refinery’s feed specification (or a link to the issued PDF), monthly or spot tonnes, delivery basis, sustainability scheme, and target laycan. Attach a recent representative CoA and, if available, a summary of your supply chain: certified collecting points, storage capacity, and loading port details. Mention any prior shipments to hydrotreaters and retention-sample policy. If phosphorus or metals are not on the CoA, say so—we will ask for the test or price the risk. We respond with questions where the file is thin: common gaps are incomplete ISCC scope, a port that cannot load flexitanks with heating, or self-declarations that do not cover new collection routes. When terms align, we propose a documented lot, agree inspection (often independent survey at loading), and draft contract language on sampling, claims, and documents. We do not auto-send cargo; each parcel is negotiated against live plant demand. Refinery buyers should treat this like any feed tender: clear spec, realistic window, surveyor rules stated upfront. Suppliers should treat HVO as a separate lane from UCOME even when the oil shares a tank—the rejection list is longer and the file work is heavier, but repeat offtake rewards origins that stay consistent.
Frequently asked questions
Can UCO be used to make HVO?
Yes. UCO is one of the standard waste feedstocks for hydrotreated renewable diesel once pretreatment removes water, solids, and catalyst poisons. Not every UCO tank qualifies for every HVO plant: phosphorus from lecithin, metals from frying equipment, chlorine from cleaning chemistry, and occasional polymer residues can tighten limits beyond the usual FFA and MIU screen. Refineries publish their own maxima and may trial a parcel before repeating origin. Send your full spec sheet response, not only FFA, when you ask an HVO buyer for acceptance.
What is the difference between HVO and UCOME?
UCOME is fatty-acid methyl ester biodiesel made by transesterification; it carries oxygen and ester chemistry that blending rules treat differently from fossil diesel. HVO is paraffinic renewable diesel from hydrotreating: oxygen is removed and the product behaves like a high-cetane gasoil cut in many markets. Both can start from UCO, but the conversion unit, coproducts (including renewable naphtha or LPG on HVO), and compliance paperwork differ. A lot rejected for HVO on metals might still work for UCOME, and the reverse happens on FFA or gum content—always ask against the actual process, not the feedstock name alone.
Does UCO for HVO need ISCC certification?
For EU renewable diesel sold with RED credit, the producer must prove sustainable waste origin, usually via ISCC EU and Union Database entries linking each tonne. The certificate sits on collecting and trading steps in the chain, not on Turco & Co as a trading house unless a specific scope applies to our activity. Non-EU HVO plants may use ISCC PLUS, national schemes, or buyer-specific rules. Missing or broken chain-of-custody blocks the sale even when lab quality is fine, so share scheme type, certificate numbers, and whether the lot is already declared in UDB before you fix a freight rate.
How do HVO buyers prefer UCO to be delivered?
Large European refineries often buy CIF ARA or DAP to their pretreatment inlet, with duty and RED status clarified in the contract. Asian and US units more often work FOB origin or CIF to their coast, sometimes in bulk vessel rather than flexitank. HVO plants run continuously, so delivery windows and demurrage matter: a delayed parcel can miss a campaign slot. Specify incoterms, port, acceptable packaging, heating need for winter loadings, and whether the refinery sends its own surveyor. We align documented lots to that basis and arrange independent inspection at loading when the contract calls for it.
