Locked to a single producer, or chasing a hard-to-find chemical? Send us the product you run. We identify the chemistry, find another maker or a comparable grade, vet it, and supply it in bulk.
A second source is a second qualified supplier for a chemistry you already buy — insurance against a single producer's price move, allocation, discontinuation, or plant outage. RawSource works from the product you run: we identify what it actually is (INCI, CAS, or functional chemistry), find another manufacturer of the same material or a comparable grade, vet the source, and supply it in bulk. We are independent of any single producer and own no plant, so we match a requirement across suppliers and geographies instead of steering you to one line. You keep your formulation; you gain a backup.
Start with what you have: a product name, a brand, a spec sheet, or a sample. We resolve it to a generic chemistry — the CAS number, INCI name, or the functional description a producer would recognize — then match it against makers we can source from. Where an exact match is not available, we return the closest comparable grade with the differences named, not hidden.
Often, yes. Most branded specialty grades are a specific chemistry sold under a trade name; a comparable grade from another producer will meet the same specification for many applications, and we say plainly where it will not. We reference a competitor grade only as a truthful comparison ("comparable to") — never as a claim that our material is that brand or that we are affiliated with it.
Single-supplier dependence is the quiet risk in a bill of materials. One producer's allocation, a REACH or TSCA restriction, a force-majeure, or a 30% price move can stop a line that has no qualified alternative. A pre-qualified second source turns that from a crisis into a purchase order. It also gives you leverage the next time a sole supplier quotes a renewal.
Illustrative examples of generic-to-branded equivalence. Send the product you run and we return the identity and the comparable grades we can source. Trade names are shown only as truthful nominative references.
| A grade you might run | The generic chemistry | What we source |
|---|---|---|
| Fumed silica (e.g. comparable to Aerosil / Cab-O-Sil / HDK) | Synthetic amorphous fumed silica | A comparable fumed-silica grade at your surface-area and treatment |
| Xanthan gum (e.g. comparable to Kelzan / Rhodopol) | Xanthan gum, CAS 11138-66-2 | A food- or industrial-grade xanthan at your mesh and viscosity |
| PVP (e.g. comparable to Kollidon / Plasdone / Luvitec) | Polyvinylpyrrolidone, CAS 9003-39-8 | A K-value-matched PVP grade |
A second-source supplier is a second qualified manufacturer for a chemistry you already buy, held ready so a single producer's outage, allocation, price move, or discontinuation does not stop your line.
Both are trade names for synthetic amorphous fumed silica — AEROSIL from one producer, Cab-O-Sil from another. Grades differ by surface area and surface treatment, so a comparable grade is matched on those parameters, not on the brand. We can source a comparable fumed silica to your spec.
Often, yes. We help get the chemistry identified from a sample or a spec sheet, then source a comparable grade you can buy in bulk. See reverse-engineering and product matching.
No. We are a sourcing house, independent of any single producer. That independence is what lets us match a requirement across suppliers and geographies rather than steer you to one line.
A mutual NDA is available before any brief is shared. Your bill of materials and the products you run stay yours.
RawSource is a raw-material sourcing house. Guidance here is advisory; candidate materials, grades, and regulatory notes are for reference, and suitability, performance, and regulatory compliance in your finished application remain the buyer's responsibility. Always consult the current Safety Data Sheet (SDS) before handling.
