Capture the brief
Write the intended application, grade, concentration, quantity unit and whether the lot is a sample, trial or firm order.
Independent sourcing partner
Fine chemicals for measured US procurement briefs
Fine Chemicals Sourcing is an independent desk that collects chemical name, CAS number when known, grade, purity or concentration, quantity, packaging and US destination, then requests factory wholesale quotations. This site does not operate a plant, hold inventory or certify a product.
Specification brief
| Brief field | What to record | If still unknown |
|---|---|---|
| Identity and assay | Record assay, impurity profile and moisture questions before comparing unit price. | Leave the cell open instead of filling a family-typical value. |
| Documents | Ask for the current SDS, TDS and certificate of analysis on the exact quoted lot format. | A related-grade file is not evidence for this request. |
| Pack and transport | Keep transport class, UN number and package type as open supplier answers. | Do not infer UN class from a catalog family name. |
19 identity and assay checks collected before two factory lines are compared
6 document kinds requested: SDS, TDS, CoA, TSCA, REACH and transport notes
10 specification questions used for grade, moisture, residual solvents and pack net
7 packaging and destination checks kept beside any unit price
5 open review items returned instead of filling blanks from a family page
Same-basis quotation steps
A comparable quote starts with one chemical basis. Similar trade names can hide different assay windows, residual solvent limits or package net contents.
Lock document asks
List SDS, TDS, CoA format, TSCA status for US supply and any REACH or GMP questions that the buyer still needs answered.
Align delivered scope
Ask each factory to state packaging, Incoterm, freight, duties and exclusions before any unit-price comparison.
Keep alternatives separate
If a factory offers another grade or package, place it on its own line and obtain buyer approval.
Use-case pairs that change the RFQ
Application context does not prove suitability. It only changes which specification and document fields belong on the first request.
Formulation trial
Buyers usually need a small pack, appearance notes, assay and a sample decision method before a recurring forecast.
Process intermediate
Record impurity profile, residual solvents and batch-size questions that affect later synthesis steps.
Distribution restock
State palletization, labeling language, shelf-life statement and US destination constraints.
Regulated review
Ask the named supplier for TSCA, REACH or GMP evidence that belongs to the quoted product, not this desk.
Packaging and transport questions
Which package fields belong on the first quote?
Ask for package material, net content, inner liner, pallet pattern and whether the quoted weight is net or gross. Flash point, density and UN number stay as supplier answers for the exact concentration.
Can this page decide hazardous transport class?
No. Final classification follows the exact SDS, destination rules and the carrier. This desk only records the buyer destination and open transport questions.
How should optional budget be written?
State currency and whether the figure is per kilogram, per drum or for the whole order. High-end, mid-range or budget is a preference, not a rating of any factory.
