Azodicarbonamide ADC/AC Blowing Agent CAS 123-77-3 for Plastics and Rubber Export Sourcing
Buyer-facing sourcing profile for azodicarbonamide ADC/AC blowing agent supplied as yellow powder, CAS 123-77-3, typically offered at 98%-99% purity for plastic and rubber foaming applications. Overseas buyers should verify grade selection, particle size, decomposition temperature range, gas evolution, UN 3242 Class 4.1 transport classification, export documents, and destination-market restrictions before RFQ confirmation.

Package and route
Packing notes
Confirm whether export packing is 25 kg carton, bag-in-carton, fiber drum, or palletized carton before order placement.
Request pallet dimensions, net/gross weight, container loading estimate, and moisture-protection details for sea or air freight planning.
Confirm DG-compliant marks, labels, and packaging certificates where required for UN 3242 Class 4.1 shipment.
Ask whether sample packing differs from commercial export packing and whether courier acceptance is available for the destination country.
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
Industrial foaming additive sourcing for plastics and rubber formulations
Grade comparison for PE, PS, EVA, PVC, TPR, NBR, or SBR foam production lines
RFQ preparation for ADC blowing agent with verified CAS, purity, particle size, and DG export status
Supplier qualification for repeat import of chemical auxiliary additives
Document-readiness check before dangerous-goods international shipment
How we compare
Sourcing options
Request quotation by exact grade code and target application rather than generic ADC description.
Compare high-temperature, low-temperature, EVA-focused, PVC/artificial leather, and injection-foaming grade options by decomposition profile and particle size.
Ask for a small pre-shipment sample only after confirming DG courier feasibility and import acceptance.
For India export sourcing, request CIF/CFR/FOB options with DG freight confirmation and destination port feasibility.
Evaluate suppliers by batch COA consistency, document readiness, export history, and ability to provide compliant DG packaging.
Human review
Compliance notes
CAS, EINECS, purity, grade code, and SDS must be checked against the buyer's destination-market requirements before procurement.
UN 3242 and Class 4.1 status indicate dangerous-goods export awareness is required; freight route and carrier acceptance should be confirmed early.
Request current SDS, TDS, COA, commercial invoice, packing list, certificate of origin, and DG transport documents where applicable.
For India-bound inquiries, confirm HS code, import documentation expectations, port restrictions, and buyer-side approvals with a licensed customs or compliance professional.
Do not rely on marketplace listing text as a regulatory determination; verify the exact product grade and intended industrial use with documents from the manufacturer or exporter.
Food-contact, consumer-product, medical, or other sensitive end uses may require additional destination-specific review.

Questions to confirm
Which exact ADC/AC grade code is being quoted, and what are its decomposition temperature range, gas evolution value, and average particle size?
Can the supplier provide recent COA batches showing purity, moisture, ash or residue, particle size distribution, and any relevant impurity limits?
Is the quoted material CAS 123-77-3 azodicarbonamide only, or is it a modified/masterbatch/activated blowing agent blend?
What is the confirmed UN number, hazard class, packing group if applicable, and export packing certificate availability?
Are SDS and TDS available in English, and do they match the quoted grade and latest production batch?
What is the MOQ, lead time, monthly export capacity, and sample availability for the requested grade?
Can the supplier support shipment to India, including DG booking, certificate of origin, invoice, packing list, and any requested inspection documents?
What packing formats are available besides 25 kg/carton, and can palletization or container loading be customized?
