Azo-Bis-Iso-Butyronitrile, often called AIBN, turns up time and again in the world of polymer science. Out in the lab, it’s valued as a radical initiator. Chemically known by its formula C8H12N4, this white, crystalline powder drives the creation of PVC, ABS, and many copolymers. Its structure packs twin cyano (–CN) groups, with azo bonds in the middle – that’s where the magic of radical generation happens. With a molecular weight of 164.21 and density hovering near 1.1 g/cm³, AIBN has carved out its space in the chemical supply chain. The HS Code, often used to track and clear customs, usually lands at 2927.00 for nitrile organic compounds like AIBN.
I walk the halls at chemical trade shows and see China leading AIBN production. Competitive factory price makes a difference. In global chemical-buy cycles, purchasing directly from a certified Chinese supplier cuts out the middle layer. Production lines run under ISO and SGS audited standards. Most plants comply with REACH and offer product MSDS, TDS, and certifications like Halal and Kosher. These steps matter; buyers want more than just a good quote. They’re hunting for a partner who understands shipment risks, paperwork, and hazard control during ocean or air transit.
Anyone who’s handled raw AIBN knows: label it, store it, treat it with respect. The material kicks off free radicals at about 65°C, so warmth turns this powder into a safety concern quickly. Factories stick to UN packing regulations for harmful substances. Proper containers, SDS on hand, and trained shippers cut down accidents. Labs keep AIBN far from spark and flame sources. Most factories send liter bottles for lab work, drums for plants. Shipping departments recommend FOB or CIF terms for bulk international orders, always with safety paperwork attached, and usually a sample goes in the box for test runs before full purchase.
Industry likes predictability, so China’s supply chain usually handles MOQs that start at 25 kilograms – a drum or two – though dedicated buyers sometimes lock in higher volumes for price breaks. From my own network, purchasing managers ask for custom quotes based on trade policy shifts, changes in VAT, or updates from the US and EU on customs tariffs. Prompt response to inquiry builds loyalty. Buyers check certification: REACH, SDS, Halal, Kosher, ISO, OEM options for private labeling. Some request batch-specific COAs tested by third-party SGS labs. These aren’t just hoops to jump; they turn up differences that help buyers avoid disruption.
AIBN’s reach stretches far. Makers of adhesives, plastics, pharmaceuticals, and even some specialty lab reagents demand tight product specifications. From structure tracing to final item on a shelf, the material faces regular scrutiny for safety – not just by user labs, but by customs, safety boards, and internal QA officers. News from 2024 points to continued tightening on chemical handling and traceability law. Factories pivot to carry full documentation, aiming for longer-term partnerships with buyers who need compliance for Halal, Kosher, ISO, and market registration worldwide. An engaged supplier doesn’t wait for problems – the best factories already adapt safety and trade rules into every batch before shipping.
