D2, EN 590 and Gasoil: Decoding Diesel Nomenclature for Trade

Buyers still asking for D2 are usually looking for EN 590 diesel but using a label that died with the Soviet standard GOST 305-82. That grade capped sulfur at 2,000 ppm, two hundred times the 10 ppm limit now mandatory across Europe and most OECD markets. The term survives in broker slang and spam offers because 1990s telex templates cemented the code before ultra-low-sulfur mandates rewrote global specifications. Legitimate sellers never lead with D2; they quote EN 590 10 ppm ULSD with the applicable CFPP class and FAME content. This guide decodes the nomenclature, maps legacy parameters to current EN 590 climate classes, and explains the fiscal, quality, and documentary checks that prevent off-spec deliveries and customs penalties.

You will learn how to translate a legacy D2 inquiry into an actionable EN 590 purchase order, which test methods verify each critical parameter on a Certificate of Quality, and why climate class nomination must match the discharge port and window rather than the load port. The article covers the distinction between duty-paid DERV and rebated marked gas oil, the penalties for cross-contamination, and the exact sulfur, cetane, density, FAME, cold flow, and lubricity limits that trigger claim procedures and demurrage costs in the ARA region.

What Is D2? Separating Legacy GOST Grade from Modern Trade Myth

D2 fuel is the commercial shorthand for the obsolete Soviet-era gasoil grade defined by GOST 305-82 which allowed sulfur content up to 0.2 percent by mass. The designation persists in broker slang and spam offers because legacy telex templates and early internet forums cemented the code before ultra-low-sulfur mandates rewrote global specifications. Buyers requesting D2 today usually need EN 590 compliant diesel but use the outdated label out of habit. According to the U.S. EIA, U.S. distillate fuel oil exports in 2025 decreased by 28,000 b/d (2%) compared with 2024, reflecting tighter global sulfur standards that make high-sulfur gasoil increasingly unmarketable in OECD regions.

GOST 305-82 D2 technical parameters and sulfur ceiling

GOST 305-82 D2 technical parameters and sulfur ceiling set the maximum sulfur at 0.2 percent mass equivalent to 2,000 ppm which is two hundred times higher than the EN 590 limit of 10 ppm. The standard also permitted a cetane number minimum of 45 compared with 51 under EN 590 and density between 820 and 860 kg/m3 at 15°C. These figures render the grade illegal for road use in the European Union and most major economies since 2009. Any offer quoting D2 without referencing a current EN 590 climate class signals either ignorance or an attempt to move off-spec material.

Why 'D2' persists in broker slang and spam offers

Why 'D2' persists in broker slang and spam offers traces back to the 1990s when Russian export allocations used the GOST code in telex communications and early email threads. The term survived because it is short memorable and carried an aura of "Russian origin" that some traders equated with volume availability. Modern spam blasts still lead with "D2 GOST 305-82" to harvest inquiries from buyers who have not updated their specification sheets. Legitimate sellers never lead with D2; they quote EN 590 10 ppm ULSD with the applicable CFPP class and FAME content.

Direct mapping of legacy D2 to nearest EN 590 climate class

Direct mapping of legacy D2 to nearest EN 590 climate class shows that the old summer grade aligns loosely with EN 590 Class A (CFPP +5°C) while the winter variant approaches Class F (CFPP -20°C) but fails on sulfur cetane and lubricity. The table below contrasts the key parameters so buyers can translate legacy inquiries into actionable EN 590 purchase orders.

Parameter	GOST 305-82 D2 (Summer)	GOST 305-82 D2 (Winter)	EN 590:2022 Class A	EN 590:2022 Class F
Sulfur (ppm)	2,000 max	2,000 max	10 max	10 max
Cetane Number	45 min	45 min	51 min	51 min
Density at 15°C (kg/m³)	820, 860	820, 860	820, 845	800, 845
CFPP (°C)	+5 max	-20 max	+5 max	-20 max
Lubricity (HFRR µm)	Not specified	Not specified	460 max	460 max

The table demonstrates that sulfur and cetane gaps are structural not seasonal. A buyer asking for D2 winter grade actually requires EN 590 Class F or Arctic Class 2 with 10 ppm sulfur and 51 cetane minimum. Any contract referencing D2 should be amended to cite the exact EN 590 climate class and test methods to avoid delivery disputes.

EN 590:2022, The Actual Specification Governing European Diesel Trade

EN 590:2022 is the mandatory European standard for automotive diesel fuel limiting sulfur to 10 mg/kg maximum and setting a cetane number floor of 51.0. The specification replaces all prior national grades and is the reference for physical cargo trading in the ARA zone and Mediterranean hubs. Buyers writing purchase orders must cite the exact climate class and FAME tolerance to avoid receiving off-spec parcels that fail customs or OEM warranty requirements. U.S. exports of total petroleum products rose to a record 6.6 million barrels per day in 2024 according to U.S. EIA https://www.eia.gov/todayinenergy/detail.php?id=65084.

Full specification table with test methods (ISO 3104, EN ISO 20846, EN 116)

Full specification table with test methods (ISO 3104, EN ISO 20846, EN 116) provides the analytical backbone for every certificate of quality issued at load port. Sulfur is measured by EN ISO 20846 or EN ISO 20884 delivering 10 mg/kg precision. Cetane number follows EN ISO 5165 while cetane index uses EN ISO 4264. Density at 15°C relies on EN ISO 3675 or EN ISO 12185. Viscosity at 40°C is tested per EN ISO 3104 within the 2.0 to 4.5 mm²/s band. Flash point uses EN ISO 2719 with a 55°C minimum. Cold filter plugging point follows EN 116 for each climate class. FAME content is quantified by EN 14078. Oxidation stability after FAME blending is verified via EN 15751 requiring 20 hours minimum. Lubricity wear scar diameter uses EN ISO 12156-1 limited to 460 µm.

Seasonal CFPP classes and Arctic grade availability

Seasonal CFPP classes and Arctic grade availability define the cold flow performance that determines whether a cargo can be sold in Scandinavia in January or Southern Spain in July. EN 590:2022 lists Classes A through F with CFPP steps from +5°C down to -20°C. Arctic grades extend to Class 0 (-20°C), Class 1 (-26°C), Class 2 (-32°C), Class 3 (-38°C) and Class 4 (-44°C) using the same EN 116 test method. Refiners typically switch production in September for winter grades and April for summer grades. Traders lifting from Rotterdam in December must confirm the cargo carries a Class F or Arctic certificate otherwise the parcel may be rejected at Swedish or Finnish discharge terminals.

FAME blending rules B7 max and oxidation stability EN 15751

FAME blending rules B7 max and oxidation stability EN 15751 cap fatty acid methyl ester content to protect modern high-pressure common rail injection systems. The blend must meet EN 15751 oxidation stability of 20 hours minimum at 110°C to prevent polymer formation during storage. Some national regulations such as Germany’s 10. BImSchV allow up to B7 but require seasonal FAME reductions in winter. Buyers importing into India or West Africa should verify local FAME mandates because B0 or B5 may be required by national standards overriding the EN 590 maximum. For deeper technical context on 10 ppm diesel specifications see EN 590 10 ppm diesel specifications and global uses.

Parameter	Unit	Limit	Test Method	Climate Class Range
Sulfur	mg/kg	10 max	EN ISO 20846	All classes
Cetane Number	,	51.0 min	EN ISO 5165	All classes
Density at 15°C	kg/m³	820, 845	EN ISO 12185	Class A, F
Viscosity at 40°C	mm²/s	2.0, 4.5	EN ISO 3104	All classes
Flash Point	°C	55 min	EN ISO 2719	All classes
CFPP	°C	+5 to -44	EN 116	Class A to Class 4
FAME Content	% vol	7.0 max	EN 14078	All classes
Oxidation Stability	hours	20 min	EN 15751	All classes
Lubricity (HFRR)	µm	460 max	EN ISO 12156-1	All classes

The table consolidates every mandatory limit a buyer must verify on the certificate of quality before authorizing payment under a letter of credit. Note that density and CFPP ranges shift with climate class while sulfur cetane FAME and lubricity remain constant across all grades. Any deviation on the CoQ triggers a claim procedure that can demurrage a vessel for days at $25,000 to $40,000 per day in the ARA region.

Road Diesel (DERV) vs. Non-Road Gas Oil: Same Spec, Different Tax & Dye Status

Both road diesel (DERV) and non-road gas oil meet the EN 590 specification but diverge on fiscal marking, dye, and permitted end-use to prevent costly mis-delivery. The chemical composition is virtually identical with sulfur capped at 10 mg/kg. The distinction exists solely for tax administration and regulatory control. A buyer receiving a barge or truckload must verify the marking status on the certificate of quality and the accompanying customs documentation before discharge because off-spec delivery triggers immediate customs liability and potential environmental fines.

White diesel (DERV) duty-paid supply chain

White diesel (DERV) duty-paid supply chain moves through terminals with full excise duty settled before the product leaves the rack. In the United Kingdom the duty rate stands at 52.95 pence per litre and the fuel carries no solvent dye or chemical marker. Hauliers and forecourt retailers receive a delivery ticket showing the duty point and volume corrected to 15 degrees Celsius. Any diversion of this duty-paid product into non-road machinery constitutes tax evasion and exposes the end-user to back-duty assessments plus penalties. Terminal operators in the ARA region load DERV into dedicated compartments to avoid cross-contamination with marked gas oil.

Marked gas oil (red diesel) rebated supply chain and permitted sectors

Marked gas oil (red diesel) rebated supply chain and permitted sectors operate under a reduced excise rate because the fuel is dyed with Solvent Red 24 and marked with a chemical tracer such as Solvent Yellow 124. In the UK the rebated rate is 11.14 pence per litre. Permitted uses include agriculture, horticulture, forestry, rail traction, non-commercial heating and certain marine craft. Construction and road haulage were removed from the rebated list in April 2022. Suppliers must be registered with HMRC as Registered Dealers in Controlled Oil and maintain audit trails for every litre sold. U.S. distillate fuel oil exports reached about 1.30 million b/d in 2024 according to U.S. EIA reflecting strong global demand for both duty-paid and rebated grades.

Penalties for misuse and cross-contamination risks

Penalties for misuse and cross-contamination risks are severe across European jurisdictions. In the UK HMRC can seize vehicles and impose fines up to the full duty differential plus 100 percent penalty. A single litre of red diesel found in a road-going truck tank triggers a minimum 250 pound fixed penalty plus full duty recovery. Cross-contamination at multi-product terminals occurs when shared lines or tanks are not properly flushed. Buyers should request a line flush certificate and an independent dip test on the CoQ to prove the cargo meets the correct fiscal specification before the vessel sails.

Critical Parameter Deep-Dive: Sulfur, Cetane, Density, FAME, Cold Flow, Lubricity

Each key quality parameter on an EN 590 Certificate of Quality has a defined test standard and direct operational impact so buyers can evaluate cargo suitability with confidence. The specification locks sulfur at 10 mg/kg maximum, cetane number at 51.0 minimum, density between 820 and 845 kg/m3 at 15 degrees Celsius, FAME at a maximum by volume, cold filter plugging point varying by climate class, and lubricity HFRR at 460 micrometres maximum. A deviation on any single parameter triggers a claim procedure that can demurrage a vessel for days at significant daily cost in the ARA region.

Sulfur evolution timeline from 2000 ppm to 10 ppm ULSD

Sulfur evolution timeline from 2000 ppm to 10 ppm ULSD tracks the regulatory pathway that reshaped global refining. Euro 3 in 2000 capped sulfur at 350 mg/kg. Euro 4 in 2005 dropped it to 50 mg/kg. Euro 5 in 2009 mandated 10 mg/kg ultra-low sulfur diesel (ULSD) enabling particulate filters and selective catalytic reduction. The 10 mg/kg limit is now the global benchmark for road transport. Refineries achieve this through deep hydrotreating which also reduces aromatics and improves cetane. Buyers verifying a CoQ must confirm the test method EN ISO 20846 or EN ISO 20884 is cited because older methods lack the precision required at the 10 mg/kg level.

Cetane number 51 minimum and ignition quality

Cetane number 51 minimum and ignition quality define how readily the fuel auto-ignites under compression. A higher cetane shortens ignition delay reducing combustion noise and cold-start smoke. EN 590 sets the floor at 51.0 measured by EN ISO 5165 using a CFR engine. Derived cetane number (DCN) via EN 15195 (IQT) or EN 17155 (FIT) is accepted as an alternative. Premium diesel grades often exceed 55 but the spec minimum ensures baseline performance across all European climate classes. Buyers should note that cetane improvers (2-ethylhexyl nitrate) can raise the number by 3 to 5 points but over-treatment degrades thermal stability.

Density range 820-845 kg/m3 and mass-volume conversion

Density range 820-845 kg/m3 and mass-volume conversion governs the commercial quantity on the bill of lading. Custody transfer uses volume corrected to 15 degrees Celsius per ASTM D1250 or API MPMS Chapter 11.1. A cargo loaded at 840 kg/m3 delivers 1.1905 tonnes per cubic metre while one at 820 kg/m3 delivers 1.2195 tonnes per cubic metre. The 2.5 percent density spread translates directly into revenue variance on a 30,000 tonne cargo. Terminals measure density with an oscillating U-tube densitometer (EN ISO 12185) on a composite sample. Buyers must verify the observed temperature and the correction method applied on the inspection certificate.

Cold filter plugging point seasonal management

Cold filter plugging point seasonal management aligns fuel operability with ambient temperature. EN 590 defines climate classes A through F and classes 0 through 4 with CFPP limits ranging from +5 degrees Celsius down to -44 degrees Celsius measured by EN 116. Class F (-20 max) is typical for Central European winter while Class 2 (-32 max) covers Scandinavia. Refiners adjust CFPP by varying the kerosene cut or adding flow improvers. A cargo nominated for Class F but testing at -15 degrees Celsius is off-spec for a January delivery to Warsaw. Buyers must match the nominated climate class to the discharge port and discharge window not just the load port.

Lubricity HFRR 460 µm max and biodiesel contribution

Lubricity HFRR 460 µm max and biodiesel contribution protect high-pressure fuel injection systems. The High Frequency Reciprocating Rig (HFRR) test per EN ISO 12156-1 measures wear scar diameter at 60 degrees Celsius. Hydrotreating to 10 ppm sulfur strips natural lubricity compounds so refiners dose lubricity additives or rely on FAME which inherently provides excellent lubricity. At 7 percent FAME the wear scar typically falls well below 400 µm. Buyers should verify the lubricity result on the CoQ because a reading near 460 µm signals marginal additive dosing or potential FAME under-dose which accelerates pump wear in modern common-rail engines.

From GOST to EN: Mapping 'D2' Properties to EN 590 Grades (Arctic/Climate Classes)

GOST 305-82 D2 vs EN 590:2022 property comparison table

GOST 305-82 D2 is not the same as EN 590 because the Soviet-era specification allows significantly higher sulfur and lower cetane than modern European road diesel requires. The table below aligns the critical parameters so buyers can see exactly where a cargo sold as "D2" fails EN 590 compliance. Refiners still producing to GOST typically target 2000 ppm sulfur and a minimum cetane number of 45 whereas EN 590 demands 10 ppm sulfur and 51 cetane. Density ranges also differ with GOST permitting up to 860 kg/m3 at 15°C while EN 590 caps at 845 kg/m3. Cold flow under GOST is defined by pour point rather than CFPP making direct winter operability comparisons unreliable without retesting.

Parameter	Unit	GOST 305-82 D2 (Typical)	EN 590:2022 (Grade F)	EN 590:2022 (Class 2 Arctic)
Sulfur	mg/kg (ppm)	2000	10 max	10 max
Cetane Number	-	45 min	51 min	51 min
Density @ 15°C	kg/m³	825, 860	820, 845	800, 845
Flash Point (PMCC)	°C	62 min	55 min	55 min
Cold Flow Metric	-	Pour Point	CFPP -20°C max	CFPP -32°C max
FAME Content	% V/V	0	7.0 max (B7)	7.0 max (B7)
Lubricity (HFRR @ 60°C)	µm	Not specified	460 max	460 max

Reading the table confirms that any cargo documented only to GOST 305-82 cannot legally enter the European road fuel pool without blending or upgrading. The sulfur gap of 1990 ppm is the single largest barrier because desulfurization capacity at the load port is rarely available. Buyers requiring EN 590 compliance must insist on a Certificate of Quality issued against the EN 590 standard not a GOST test report.

Climate class selection guide (A through F, Class 0-4)

Climate class selection depends on the lowest expected ambient temperature at the discharge port during the discharge window not the load port location. EN 590 defines temperate grades A through F with CFPP limits stepping down by 5°C from +5°C (Grade A) to -20°C (Grade F). For regions experiencing temperatures below -20°C the standard switches to Arctic classes numbered 0 through 4 where Class 0 requires CFPP -20°C max and Class 4 requires CFPP -44°C max. A cargo nominated as Grade F is adequate for Central European winters such as Warsaw or Vienna in January but would wax up in Stockholm or Helsinki where Class 2 (CFPP -32°C max) or Class 3 (CFPP -38°C max) is the minimum safe nomination. Refiners achieve the tighter CFPP by increasing the kerosene cut or dosing cold flow improvers which raises the FOB price so buyers should not over-specify the class.

Arctic grade EN 590 Class 2/3 specs for extreme cold

Arctic grade EN 590 Class 2 and Class 3 are distinct climate classes within the standard not separate fuel grades. Density is relaxed to 800, 845 kg/m³ to accommodate the higher kerosene fraction required for cold flow. Cloud point is not mandated in EN 590 but reputable suppliers report it because wax appearance precedes filter plugging. For operations above the Arctic Circle such as Murmansk or Tromsø buyers should nominate Class 3 or Class 4 and request cloud point data on the CoQ. Vessel segregation is critical because a single compartment of off-spec temperate diesel contaminates an entire Arctic parcel.

Trade Documentation Pack: CoQ, CoO, SDS, Inspection Certs, REACH, Sanctions Screening

Certificate of Quality from refinery or independent inspector (Saybolt, Intertek, SGS)

The Certificate of Quality is the primary proof that the cargo meets the contracted specification. It must be issued by the loading refinery laboratory or an independent inspector such as Saybolt Intertek or SGS appointed by the seller. The CoQ lists every EN 590 parameter with the test method (for example EN ISO 20846 for sulfur EN ISO 5165 for cetane) the result and the pass/fail status against the nominated climate class. Buyers should verify that the CoQ date matches the bill of lading date within 24 hours and that the inspector stamp includes the unique report number traceable to the inspector’s online portal. A CoQ issued by a trader without inspector countersignature carries no weight under a letter of credit.

Certificate of Origin and REACH registration number

The Certificate of Origin certifies the country where the diesel was refined which determines tariff treatment and sanctions exposure. Chambers of commerce in the load port country issue the CoO and it must match the vessel loading port. For entry into the EU the supplier or importer must hold a valid REACH registration number for the substance "fuels diesel" (EC 270-676-1) and include it on the SDS. Without a REACH number the cargo cannot be legally placed on the European market. Non-EU buyers should still request the REACH number because it confirms the producer has filed a chemical safety report covering the full lifecycle of the product.

Safety Data Sheet (SDS) compliance with CLP Regulation

The Safety Data Sheet must comply with Regulation (EC) No 1907/2006 (REACH) and the Classification Labelling and Packaging (CLP) Regulation (EC) No 1272/2008. It contains 16 mandatory sections covering hazard identification first aid measures firefighting accidental release handling storage exposure controls physical chemical properties stability reactivity toxicological information ecological information disposal transport regulatory and other information. The SDS must be in the language of the destination country and dated within the last three years. Section 14 (transport information) must show UN 1202 Class 3 Packing Group III and the correct marine pollutant notation. Terminals will reject discharge if the SDS is missing outdated or in the wrong language.

Sanctions screening workflow for vessel, counterparty, and origin

Sanctions screening is a mandatory pre-trade step not a post-trade cleanup. The workflow covers three layers: the vessel (IMO number checked against OFAC SDN EU consolidated list and UK sanctions list), the counterparty (seller buyer bank and beneficial owners screened for ownership or control by designated persons), and the origin (crude source and refining location verified against sectoral sanctions on Russian petroleum products under EU Regulation 833/2014 as amended). Screening must be repeated at loading at bill of lading issuance and at payment release. Many banks now require a sanctions compliance certificate from a recognized provider such as Dow Jones Risk & Compliance or Refinitiv World-Check before negotiating an LC. A single positive hit at any stage freezes the transaction until legal clearance is obtained.

Conclusion

The nomenclature gap between legacy GOST "D2" and modern EN 590:2022 creates avoidable risk in every trade cycle. Buyers who specify D2 on a contract invite delivery disputes, quality rejections, and sanctions compliance failures because the term has no legal standing in European or international regulation. The only defensible specification for European-origin road diesel is EN 590:2022 with the appropriate climate class and FAME content declared on the Certificate of Quality. Documentation rigor, CoQ, CoO, SDS, REACH registration, and independent inspection certificates, separates legitimate supply chains from the phantom cargoes and advance-fee scams that proliferate on open messaging platforms. Regional import regimes in India, Ghana, and Nigeria impose additional layer of BIS, NPA, and NMDPRA compliance that cannot be satisfied by a generic "D2" assay. Pricing must reference transparent Platts or Argus benchmarks with clearly defined premiums, Worldscale freight, and demurrage terms. Contractual safeguards require Incoterms 2020 precision, UCP 600 or ISP98 compliant payment instruments, and explicit sanctions carve-outs referencing OFAC, EU, and UK designation lists. Traders who master these elements trade physical molecules; those who cling to "D2" trade rumors.

Frequently Asked Questions

what is d2 fuel?

D2 fuel is the commercial shorthand for the obsolete Soviet-era gasoil grade GOST 305-82 which allowed sulfur content up to 0.2 percent by mass. The designation persists in broker slang and spam offers because legacy telex templates cemented the code before ultra-low-sulfur mandates rewrote global specifications. Buyers requesting D2 today usually need EN 590 compliant diesel but use the outdated label out of habit.

what is d2 gas oil?

D2 gas oil refers to the same defunct GOST 305-82 grade with a 2,000 ppm sulfur ceiling and a minimum cetane number of 45. It is not a current commercial specification in any OECD market and cannot be legally supplied as road fuel in Europe. Any offer quoting D2 gas oil without referencing an EN 590 climate class signals either ignorance or an attempt to move off-spec material.

d2, EN 590 and Gasoil: Decoding Diesel Nomenclature for Trade used for?

Historically D2 oil was used for heating, marine bunkers, and older industrial engines across the former Soviet bloc. Today the term appears almost exclusively in broker inquiries that actually require EN 590 10 ppm ULSD for road transport, non-road machinery, or power generation. Legitimate sellers translate the request into the applicable EN 590 climate class and FAME tolerance before quoting.

d2, EN 590 and Gasoil: Decoding Diesel Nomenclature for Trade requirements in europe?

There are no European requirements for D2 oil because the grade is prohibited for road and non-road use under the Fuel Quality Directive. The mandatory standard is EN 590:2022 which caps sulfur at 10 mg/kg, sets cetane minimum at 51.0, and defines climate classes by CFPP from +5°C down to -44°C. Any cargo documented only to GOST 305-82 cannot legally enter the European fuel pool without blending or upgrading.

d2, EN 590 and Gasoil: Decoding Diesel Nomenclature for Trade documents required?

No legitimate trade uses D2 documentation; a compliant transaction requires a Certificate of Quality issued at load port showing EN 590 test results for sulfur (EN ISO 20846), cetane (EN ISO 5165), density (EN ISO 12185), CFPP (EN 116), FAME content (EN 14078), oxidation stability (EN 15751), and lubricity (EN ISO 12156-1). The CoQ must state the exact climate class and be accompanied by a bill of lading, commercial invoice, and, for EU entry, a Proof of Status (T2/T2F) or customs declaration.

d2, EN 590 and Gasoil: Decoding Diesel Nomenclature for Trade cost in india?

India does not price or import D2 oil; the market trades BS VI diesel (10 ppm sulfur) linked to the Platts Arab Gulf Gasoil 0.001%S benchmark plus freight, duties, and marketing margins. Retail pump prices are revised daily by state oil companies and vary by state VAT and dealer commission. Any quote referencing D2 for India indicates a broker using obsolete terminology.

d2, EN 590 and Gasoil: Decoding Diesel Nomenclature for Trade cost in ghana?

Ghana does not have a D2 price; the National Petroleum Authority sets ex-refinery and pump prices for 10 ppm gasoil based on the Platts FOB Mediterranean benchmark plus the Unified Petroleum Price Fund margin, BOST margin, and applicable taxes. The term D2 appears only in spam offers targeting buyers unfamiliar with the current EN 590 or AFRI specifications.

d2, EN 590 and Gasoil: Decoding Diesel Nomenclature for Trade cost in nigeria?

Nigeria does not quote D2; the market prices automotive gas oil (AGO) at 50 ppm sulfur transitioning to 10 ppm, referenced to Platts FOB Mediterranean or CIF Lagos benchmarks plus NMDPRA regulatory margins and freight. The Nigerian Midstream and Downstream Petroleum Regulatory Authority publishes monthly price caps. Offers citing D2 for Nigeria are using a legacy label that does not match local specifications.

is d2 diesel the same as en 590?

No. D2 diesel under GOST 305-82 permits 2,000 ppm sulfur and 45 cetane while EN 590 mandates 10 ppm sulfur maximum and 51 cetane minimum. The sulfur gap of 1,990 ppm makes D2 structurally incompatible with European law and modern engine warranties. Contracts must cite the exact EN 590 climate class to be enforceable.

what is the sulfur content of d2 diesel?

The sulfur content of D2 diesel under GOST 305-82 is capped at 0.2 percent by mass which equals 2,000 ppm. This is two hundred times higher than the EN 590 limit of 10 mg/kg and exceeds the 15 ppm cap for U.S. ULSD and the 50 ppm limit common in many developing economies. Cargoes testing to this level cannot be sold as road fuel in any major regulated market.

how to verify a diesel cargo certificate of quality?

Verify the Certificate of Quality by confirming the laboratory is ISO 17025 accredited for each test method listed, checking that every EN 590 parameter (sulfur, cetane, density, viscosity, flash point, CFPP, FAME, oxidation stability, lubricity) has a result and a pass/fail against the nominated climate class, and ensuring the sample identity matches the bill of lading description and vessel ullage report. Cross-reference the CoQ date with the load port surveyor’s time stamp and request the full lab report if only a summary page is presented.

platts fob rotterdam ulsd 10ppm benchmark explained

The Platts FOB Rotterdam ULSD 10ppm benchmark (ticker PGAAV00) is the daily assessed price for ultra-low-sulfur diesel loading at the Amsterdam-Rotterdam-Antwerp hub with sulfur max 10 mg/kg, FAME max 7 percent, and CFPP meeting the current seasonal class. It is published in Platts European Marketscan and used as the pricing reference for term contracts, spot deals, and swap settlements across Northwest Europe. Traders must confirm the applicable climate class and any FAME tolerances because the assessment reflects a standard EN 590 parcel not a specific winter or Arctic grade.
