Natural rubber is not one interchangeable product and is not the same as synthetic rubber or a finished rubber article. A comparable record identifies the biological source and country and plot of production; separates field latex, preserved latex concentrate, cup lump, sheet, crepe and technically specified rubber; names the applicable national or buyer grade; and preserves coagulation and processing route, bale or container, dirt, ash, volatile matter, nitrogen, plasticity and other agreed test methods, sampling, laboratory, lot, quantity, currency, Incoterm, destination, delivery window and information vintage. ISO 2000:2020 provides procurement guidance for technically specified raw natural rubber, while ISO 2004:2024 covers ammonia-preserved natural-rubber latex concentrate produced by centrifuging or creaming. Neither standard certifies an offered lot or establishes a current delivered price.
ISO lists ISO 2000:2020 as the current eighth edition, confirmed in 2025, and describes a TSR grading system based on natural-rubber origin and exhibited properties, with criteria to be agreed by the parties. ISO 2004:2024 is the current seventh edition for centrifuged or creamed ammonia-preserved latex concentrate. ISO 249:2016 specifies a raw-natural-rubber dirt test but excludes surface contamination, and ISO 248-1:2021 warns that its two volatile-matter methods do not necessarily give identical results. These are bounded specification and method records, not results for an offered lot, sustainability proof, current availability or price.
Natural rubber begins with biological latex, commonly from Hevea brasiliensis, whereas synthetic rubbers are manufactured polymers and finished tyres, gloves, hoses or other articles add compounding and fabrication. Their HS codes, properties and evidence differ. Atlas retains source material, species, product form and processing stage rather than transferring a grade or observation across these boundaries.
Field latex and preserved concentrate remain liquid systems; cup lump is coagulated field material; ribbed smoked sheet, air-dried sheet, crepe and technically specified rubber follow different preparation, appearance and analytical controls. ISO 2004:2024 is specific to centrifuged or creamed ammonia-preserved latex concentrate. ISO 2000:2020 provides TSR procurement guidance. Atlas names the form and process before comparing lots.
ISO 2000:2020 proposes a grading system based on the origin of the natural-rubber content and exhibited properties, but it also leaves criteria for the parties to agree for the particular procurement. A label such as TSR, block rubber or a national grade is therefore not a complete certificate. Atlas retains the issuing scheme, grade, limits, methods, sample, laboratory, result, uncertainty and lot.
Dirt, ash, volatile matter, nitrogen, plasticity, colour and other properties answer different questions. ISO 249:2016 excludes surface contamination from its dirt method, and ISO 248-1:2021 notes that its volatile-matter procedures do not necessarily produce identical results. Atlas stores the exact method edition, preparation, basis, sample date, laboratory, result, uncertainty and tested lot rather than comparing method-free numbers.
European Commission guidance treats rubber as an EUDR relevant commodity and requires information gathering, risk assessment and, where needed, risk mitigation before covered products are placed on or exported from the EU market. Country and plot geolocation, producer, quantity, product description, legality and due-diligence-statement references remain attached to the shipment. A supplier declaration alone does not prove every lot compliant or deforestation-free.
Water, dirt, oxidation, mould, ammonia loss, foreign material, mixing, re-baling and uncontrolled storage can change evidence or comparability. Atlas retains production and packing dates, bale or tank identification, preservation system, package, seal, storage and transport conditions, blending or reprocessing history, retained sample, chain of custody and re-test date.
An ISO reference, a national TSR grade or a due-diligence statement does not establish current availability, conformity, transaction value or delivered cost. A physical estimate still needs permitted current observations for the exact natural-rubber form, grade, origin, process and compliance evidence, package and lot, 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.
No. Natural rubber comes from biological latex, while synthetic rubber is manufactured from chemical feedstocks. Their identity, specifications and evidence are separate.
No. Latex concentrate is a preserved liquid product; TSR is coagulated, processed and baled raw natural rubber graded under a technical specification.
No. It defines guidance, specifications or test methods. Conformity still needs an identified sample, method, laboratory, results and linkage to the offered lot.
No. It addresses regulatory due diligence for covered market activity. It does not establish physical grade, test conformity, availability or delivered price.
Species and origin, country and plot where required, latex or coagulated form, process and grade, test methods and results, bale or tank and lot, traceability and custody, quantity, currency, Incoterm, destination, delivery window and evidence date.
