Sourcing process
Coagulant liquids, dry flocculants and inhibitor concentrates are easy to mis-compare when active content, charge type, residual notes and drum liner are left off the RFQ. This service page lists the fields we keep on one worksheet so factory replies from water treatment chemical distributors can be read side by side. Water Treatment Chemical Sourcing does not blend reagents and does not certify jar-test results.
Same-basis steps
Record coagulant versus flocculant versus biocide versus inhibitor preference, requested active content, charge type, molecular weight and pH if known, and whether powder, emulsion or solution is expected. Leave the field blank when the buyer wants suppliers to propose.
Ask for bag material, net kilograms, pallet pattern, and whether the liquid ships in drums or IBCs. A 25 kg bag and a 1,000 kg tote are not the same landed unit until the quote says so.
Product subtotal, bagging, samples, testing, freight, duties, and destination charges stay in separate cells. Unit price is not compared until currency, quantity, Incoterm, and exclusions match.
ISO 9001, REACH status, TSCA statements, and lead time remain supplier answers for this SKU. Alternatives go on a second line pending buyer approval.
Typical intake notes include CAS number where known, assay or solids content, viscosity method, density, pH, moisture, particle size for powders, flash point where listed, UN number, and package net content. Those fields are copied into the RFQ so two factories answer the same question. They are not published here as a catalog of products we warehouse.
When a mill proposes a substitute charge type or a different emulsion solids range, park it on a second row. Do not blend unit prices across unmatched configurations. Residual monomer, trace metals, and UN number still come from the exact SDS after the product is named. Handling, storage and mixing stay with qualified reviewers at the destination.
Optional budget should identify currency and whether it applies per kilogram, drum, IBC or complete order. High-end, mid-range, budget or undecided is a buyer preference for documentation depth, not a verified rating of water treatment chemical distributors.
Document questions
Ask for the method behind solids or assay numbers. A brochure active-content range is not a CoA for the lot that will ship.
If the receiving specification names anionic, cationic or nonionic polymer, request the method and the lot statement that will travel with the CoA, not a generic family claim.
Define whether the sample checks identity, appearance, viscosity, charge response or packaging. Pass/fail stays with the buyer lab. This desk does not run plant trials.
UN number, packing group, and whether the liquid is classified for carriage are SDS-driven. Final freight follows carrier rules, not this page.
Include grade, charge type, quantity, packaging, US destination, and delivery timing. Optional budget and supplier preference can be added without changing the original requirement text.
