Identity locked or marked open
Chemical name, CAS number if known, charge type, and internal code. If CAS is unknown, write that fact instead of guessing a neighboring flocculant.

Polyacrylamide manufacturer questions to close before the inquiry
Use this page as a pre-RFQ gate. It restates specification, document, sample, and approval items that should be decided or explicitly left open. It is not a sustainability statement and it does not certify any mill.

GATE ITEMS
Checklist items that change quote comparability
Form and process window
Powder, emulsion, or solution; active content; molecular weight; pH. A cationic emulsion is not interchangeable with an anionic powder on the same make-down skid.
Quantity and packaging
Kilograms or drums, sample versus production, bag or IBC, net content, and pallet notes. MOQ answers are unusable if the package is undefined.
Documents requested
Current SDS, TDS, CoA field list, and any TSCA, REACH, ISO, GMP, or transport statement tied to the quoted SKU. Related-grade files stay out of the comparison.
Selection considerations that remain unresolved on purpose
Buyers often argue whether a cheaper anionic powder can replace a cationic emulsion, or whether a mid-molecular-weight grade can replace a high-molecular-weight grade after a plant trial. Those are process decisions. This checklist only forces the two options onto separate quote lines with their own viscosity, residual-acrylamide, and document packs.
Another recurring dispute is whether a family SDS plus a verbal “same chemistry” claim is enough to receive material. The conservative path used here is to treat handling, storage, residual monomer, and UN number as unknown until the exact-product SDS arrives. That path is slower; the faster path accepts more residual risk. This desk does not choose the risk appetite.
BEFORE YOU SEND
Approvals that this site cannot give
- Fitness for a named clarifier, belt press, or centrifuge is a buyer trial outcome.
- Potable-program, residual-acrylamide, or NSF-style letters are supplier or buyer documents, not ours.
- Transport and storage follow the SDS, DOT or IMDG class, and the carrier, not this checklist.
- Budget figures and high-end/mid-range/budget labels are preferences, not audited factory tiers.
- No lowest-price or savings percentage is attached to a completed checklist.
Submit the closed polyacrylamide brief
When identity, residual-acrylamide questions, bag or tote size, destination, and SDS/TDS/CoA requests are ready, send them. If they are not, list the blanks so mills do not fill them with a family flocculant default.
