Propylene

Commercial profile

Product characteristics and commercial applications

Propylene is evaluated by its declared grade, physical form, intended commercial use and the buyer’s transaction-specific requirements. The points below are due-diligence and quotation criteria, not a representation of stock or a guaranteed specification.

• Aromatic, olefin, alcohol, glycol or additive stream defined primarily by purity and component composition.
• Water, colour, acidity, distillation range and inhibitor content may affect downstream processing.
• Hazard class, temperature sensitivity and polymerisation risk vary materially between products.
• The named chemical, grade and test method must be unambiguous in the contract.
• Chemical synthesis, polymer, resin, fibre, solvent, coating or additive manufacture, depending on product.
• Fuel blending or oxygenate applications where lawful and technically approved.
• Heat-transfer, antifreeze or other industrial formulations for compatible glycols and alcohols.

Buyer input

Parameters normally specified by buyers

• Purity and component composition
• Water content
• Distillation range
• Colour and acidity
• Inhibitor content where applicable

Document control

Applicable specification frameworks

• ASTM, ISO or contractual chemical grade
• Certificate of analysis
• Safety data sheet
• REACH and transport documentation where applicable

Execution planning

Packaging and bulk-delivery alternatives

• Bulk chemical vessel, rail tank car or road tanker with compatible construction and previous-cargo controls.
• ISO tank, drum or IBC where permitted by the product safety and transport classification.
• Flexitank only for products expressly approved by the manufacturer, carrier and buyer.
• Seals, nitrogen blanketing, inhibitors or temperature control must be specified where required.

Execution planning

Storage and handling considerations

• Use compatible tanks and transfer systems with grounding, bonding and vapour controls.
• Control heat, ignition sources, moisture and exposure to incompatible chemicals.
• Maintain inhibitor, nitrogen-blanket or temperature conditions where the product requires them.
• Retain batch, tank, seal, sampling and safety records throughout custody.

Document control

Certificate of analysis and inspection requirements

• Seller or producer certificate of analysis identifying the batch, lot or cargo and reporting agreed parameters with units and test methods.
• Certificate dates, laboratory identity and sample basis must be consistent with the offered product and loading programme.
• Independent quality and quantity inspection by SGS, Bureau Veritas, Intertek or another mutually accepted inspector where contractually agreed.
• Sampling, sealed-retention samples and quantity determination by draft survey, calibrated meter, weighbridge or another agreed method.

Document control

Origin and chain-of-custody documentation

• Certificate of origin or equivalent producer, refinery, plant or mine documentation appropriate to the commodity.
• Evidence of the seller’s authority and a traceable document chain linking producer, authorised seller and transaction counterparties.
• Transport, warehouse, terminal, export and customs documents appropriate to the agreed delivery route.
• Sanctions, export-control, responsible-sourcing and destination requirements must be cleared before contract and shipment.

Execution planning

Typical logistics and Incoterm considerations

• State the applicable Incoterms® 2020 rule and the precise named port, terminal, warehouse or place.
• Confirm loading and delivery windows, nominated transport mode, capacity, route and receiving-facility compatibility.
• Allocate freight, insurance, export/import clearance, title transfer and risk transfer explicitly in the contract.
• For vessels, agree nomination, laycan, notices, loading/discharge rate, laytime and demurrage provisions.
• For land movements, confirm axle, wagon, terminal, border, dangerous-goods and appointment requirements.

Buyer input

Information required in a quotation request

• Exact product name, grade, standard, composition and acceptable tolerances.
• Required quantity, unit, shipment size, delivery schedule and contract duration.
• Destination, named place or port and requested Incoterms® 2020 rule.
• Preferred packaging, transport mode, loading window and receiving constraints.
• Required inspection company, certificates, origin evidence and regulatory documents.
• Buyer legal entity, authorised contact, intended use, KYC information and proposed payment instrument or commercial terms.

Availability and contractual basis

Specifications, documents, quantities, delivery arrangements and availability remain subject to the verified seller’s written offer and the definitive contract. Helianthus acts solely as an independent facilitator, does not hold inventory or take title to the commodity, and does not warrant availability, ownership or performance by any counterparty.
