Latest reviewed evidence
Codex CXS 210-1999, revised in 2024, defines palm oil as oil from the fleshy mesocarp of Elaeis guineensis fruit and separately defines palm olein and palm stearin as fractions. Its appendix gives palm-oil identity ranges including iodine value 50.0–55.0, saponification value 190–209 milligrams KOH per gram and unsaponifiable matter no more than 12 grams per kilogram. For refined oils generally, Codex lists acid value up to 0.6 milligrams KOH per gram, peroxide value up to 10 milliequivalents per kilogram, insoluble impurities up to 0.05 percent and volatile matter up to 0.2 percent. MPOB's current register identifies MS 814:2025 as Malaysia's third-revision palm-oil specification; the full purchased standard and the buyer's contract govern a Malaysian lot. These are identity and reference limits, not test results, proof of destination compliance or a live physical price.

Mesocarp oil and palm-kernel oil are separate commodities
Codex defines palm oil from the fleshy mesocarp of Elaeis guineensis fruit, while palm-kernel oil comes from the kernel. Their fatty-acid composition, refining behavior, identity tests, fractions and commercial uses differ. Atlas records the source material and applicable named-oil standard and never transfers a palm-kernel specification, laboratory result or price to RBD palm oil.
CPO and RBD palm oil have different processing states
Crude palm oil is the mill product and refining feedstock. MPOB describes RBD palm oil as oil obtained from crude or semi-refined palm oil by bleaching, deodorizing and physical de-acidification; chemically neutralized and deodorized routes are separately identified in Malaysian terminology. Atlas retains the crude feedstock, refinery, route, processing dates, bleaching earth and filtration controls, deodorization record, mass balance, tank and lot rather than treating every light-coloured palm oil as the same RBD product.
Whole RBD palm oil, olein and stearin stay separate
Palm olein is the liquid fraction and palm stearin the high-melting fraction obtained by fractionating palm oil. Codex assigns separate identity characteristics to those fractions, including an iodine value of at least 56 for palm olein and no more than 48 for palm stearin, while palm oil itself is listed at 50.0–55.0. Atlas requires whole-oil or named-fraction status and does not transfer cloud point, melting behavior, application claim or price across them without a documented fractionation and mass-balance basis.
Quality limits require a representative lot test
Acid value or free fatty acids, peroxide value, moisture and volatile matter, insoluble impurities, soap, colour and sensory condition answer different quality questions. A standard ceiling is not a certificate. Atlas keeps the sampling plan, laboratory, method, result, uncertainty, test date, tank and lot attached and checks whether the contract uses Codex, MS 814:2025, a PORAM term or another destination-specific specification.
Identity and processing-contaminant evidence are different controls
Iodine value, fatty-acid profile, sterol profile, refractive index, density, saponification value and unsaponifiable matter support named-oil identity; they do not establish process safety. Refined-oil diligence also needs destination-specific evidence for glycidyl esters, 3-MCPD and its esters, mineral-oil hydrocarbons, pesticide residues and other applicable contaminants. EU rules illustrate why the exact food category, use and effective date must accompany a result rather than being inferred from an RBD label.
Custody and sustainability claims need their own provenance
Mill and plantation origin, legal-harvest evidence, certification scheme, supply-chain model, certificate number and status, mass-balance or segregated claim, refinery, tanks, previous cargoes, transport and documents remain explicit. A country name, marketplace badge or refinery statement does not by itself prove certified, deforestation-free, segregated or traceable product.
A quality limit does not establish a delivered RBD palm-oil price
Named-oil identity and refined-oil limits do not establish current availability, lot conformity, transaction value or delivered cost. A physical estimate still needs permitted current observations for the exact whole RBD palm-oil specification, origin and refinery, quality and contaminant evidence, sustainability scope, package or tank, lot and quantity, currency, Incoterm, load and destination points, delivery window, freight, duties and information vintage. Atlas withholds a physical estimate when those observations or usage rights are missing.
