Water Decoloring Agent DCA Liquid CAS 55295-98-2 for Textile and Dye Wastewater Applications
Sourcing candidate for a liquid water decoloring agent identified as DCA / quaternary amine organic polymer flocculant, offered for textile, dyestuff, paper, and industrial wastewater color-removal applications. Buyers should confirm CAS 55295-98-2, active/solid content, pH, viscosity, impurity limits, packing format, SDS/COA readiness, HS code, and export transport classification before RFQ or sampling.

CAS number, grade, assay, and impurity profile
SDS, COA, TDS, HS code, and transport classification
Destination-market import documents before supplier matching
Package and route
Packing notes
Listed packing options: 30 kg pail, 250 kg plastic drum, and 1250 kg IBC tank
Confirm net weight, gross weight, palletization, container loading quantity, and whether IBCs/drums are export-grade
Request photos/specifications for drum, pail, IBC, seal type, and labeling before shipment
Confirm shelf life, batch traceability, production date format, and storage range stated on COA or label
For samples, confirm sample quantity, sample concentration, courier eligibility, and whether sample matches commercial batch specification
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Specification comparison for liquid DCA water decoloring agent supply
RFQ preparation for textile and dyestuff wastewater chemical procurement
Distributor product-line screening for water-treatment chemicals
Sample evaluation against buyer-defined wastewater color and COD test protocols
Bulk packing comparison between pails, drums, and IBC tanks
Document-readiness review before import or customs filing
How we compare
Sourcing options
Request bulk quotation for 250 kg drums or 1250 kg IBCs with COA and SDS attached
Ask for a paid or free representative sample tied to the same specification as commercial shipment
Source under buyer-defined active content, pH, viscosity, density, and impurity limits
Arrange third-party inspection and pre-shipment sample retention for first order
Compare suppliers by CAS verification, batch consistency, DG status, export documentation, and loading quantity rather than headline price only
Human review
Compliance notes
Request current SDS in GHS format, COA, TDS, product label, and transport classification before purchase
Do not rely on marketplace certification badges as regulatory approval; verify REACH, SGS, ISO, or other claims with document copies and scope
Confirm whether the product is regulated as dangerous goods for sea, air, or road transport under the applicable export route
Confirm destination-country import requirements, chemical inventory status, and customs documentation before ordering
CAS, formula, EINECS, and concentration information should be cross-checked because the listing contains limited and potentially inconsistent identity data
Performance claims such as greater than 95% decolorization or COD removal should be treated as supplier application data and validated by buyer-side testing
