Industrial-grade toluene diisocyanate sourcing candidate listed with TDI 80/20, TDI 65 and TDI 100 options. Buyer review should prioritize CAS and isomer-ratio confirmation, current COA matching the shipped lot, hydrolyzable chlorine, acidity, APHA color, drum packing, dangerous goods documentation, and destination-country import acceptability. This is not a toluene solvent listing and should be screened carefully for buyers searching specifically for toluene in Vietnam.

Package and route
Packing notes
Listed packing: 250 kg net in new steel drum
Listed transport package: 250 kg iron drum, drum with pallet
Ask whether drums are UN-rated and suitable for the quoted DG classification and shipping mode
Confirm pallet type, drum count per pallet, net/gross weight, container loading plan, and whether nitrogen blanketing or sealed-head drum details are included in the offer
Request photos or specifications for drum markings, batch labels, seal numbers, and export packaging condition before shipment
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Procurement evaluation for TDI 80/20 used in flexible polyurethane foam production
Sourcing review for TDI 65 used in high-resilience soft foam applications
Sourcing review for TDI 100 used in cast elastomers and coatings applications
Distributor RFQ preparation where lot COA, DG paperwork, and export packing need to be confirmed
Supplier comparison for industrial-grade aromatic diisocyanate imports
How we compare
Sourcing options
Request separate quotations for TDI 80/20, TDI 65, and TDI 100 rather than accepting a mixed product title
Ask for firm offer based on 250 kg new steel drums with palletized export packing
Request lot-specific COA and SDS before proforma invoice approval
Use third-party pre-shipment inspection for drum condition, labeling, seal numbers, and batch match
Compare supplier offer against established origin brands and confirm whether product is producer-direct or traded stock
For Vietnam, screen as a TDI import candidate only; use separate sourcing for toluene solvent if that is the actual requirement
Human review
Compliance notes
TDI is a hazardous industrial chemical and should be reviewed under destination-country chemical inventory, import licensing, workplace chemical, and dangerous goods transport requirements before ordering
Supplier should provide current SDS, COA, commercial invoice, packing list, certificate of origin if needed, transport DG declaration, and any destination-specific documents requested by the buyer or forwarder
Verify the correct CAS number, UN number, hazard class, packing group, HS code, and regulatory identifiers against the exact TDI grade and isomer ratio being supplied
Listed HS code: 292910; buyer should confirm with customs broker for the importing country
Do not rely on marketplace text as a regulatory determination; confirm all DG and import requirements with qualified logistics and compliance parties
For Vietnam inquiries, confirm whether the buyer needs TDI as a polyurethane raw material or toluene solvent, since the search keyword and listed product do not match exactly
