Market · Monopropylene glycol
Monopropylene glycol suppliers: producers, distributors and importers
Search for "propylene glycol suppliers" and you get distributors selling drums and IBCs. That's useful for 200 litres. For bulk industrial MPG the real question is different: which of those names are independent supply, and which resell the same constrained upstream material?
Identity: one product, several grades
| Name | Propylene glycol, monopropylene glycol (MPG), propane-1,2-diol |
|---|---|
| CAS | 57-55-6 |
| Customs | HS 2905 32; CN 2905 32 00 |
| Grades | Industrial / technical; USP/EP (pharmacopoeia) and food grades; bio-based grades made from glycerine |
Grade is a specification, not a different product. The same producer may sell industrial and USP/EP material through different channels and at different prices, and a buyer of antifreeze-grade MPG does not need pharmacopoeia testing.
Producer, distributor, importer: why the difference decides everything
| Role | What it is | What to check |
|---|---|---|
| Producer | A plant making MPG, most commonly from propylene oxide, or from glycerine in bio-based routes | Whether it sells bulk to traders at all, or only through contracts and appointed distributors |
| Distributor | Sells packed and bulk material from producers | Whose material it is; minimum lot; storage location |
| Importer / stock point | Brings in material from outside the region, often by ISO tank, flexitank or drums | Origin, packaging, where the stock sits, incoterm |
| Web reseller | Small-pack online sellers | Usually not incremental bulk supply |
In a regional market, dozens of resellers can depend on the same one or two upstream sources. When that source is short, adding more resellers to a sourcing list adds no volume. The useful unit is the production pool, not the web listing.
Three questions before an RFQ
- Production pool: does an actual plant stand behind this offer, and is it independent of the supply you already have?
- Commercial access: is there an entity that will sell to a trader of your size, with a route to contact it?
- RFQ-ready: is there enough, such as grade, packaging, loading point and a named desk, to send a serious enquiry?
OxyLens grades MPG supply along exactly these lines, and records unknowns instead of filling them in.
What public data can and cannot tell you
- REACH registration identifies manufacturers and importers, and sometimes an "only representative" for a non-EU producer. It confirms legal identity, not willingness to sell to you.
- Safety data sheets sometimes name the real manufacturer behind a reseller. Often they are silent or masked. Silence is itself a finding.
- Official trade statistics under CN 2905 32 00 show country-level imports, origins and average unit values. That is a solid benchmark for how much comes from where. They never say which company imported it, so they can't be turned into a supplier list.
- Company product pages give grades, packaging and loading points. The best ones name a sales desk.
Landed economics matter as much as price
For bulk industrial MPG, what you compare is delivered cost and reliability, not the headline price. Origin, transport mode (road tanker, ISO tank, flexitank or drums), loading point, lead time, documentation and regulatory status all move the landed figure. A cheaper origin can lose to a nearer plant once route and lot size are included. That's why OxyLens records the loading or stock location and packaging as evidence alongside the company.
What OxyLens looks for in this market
- Plants and the entities that can actually sell their output in bulk.
- Distributors and stock points with named desks and stated origin.
- Links between resellers and upstream producers, stated as fact where documents show it and as inference otherwise.
- Bio-based routes connected to the glycerine market.
