20 Inch Wire-Wound Cylindrical Filter Element for Industrial Liquid Filtration
Industrial wire-wound filter element candidate for buyers sourcing replacement or custom filtration cartridges. Key checks should focus on cartridge length, OD/ID, micron rating, yarn and core material, operating temperature limits, liquid compatibility, packing dimensions, export documents, and HS code confirmation. This is a filtration component rather than a chemical substance, so CAS-based chemical identity checks are generally not applicable unless filter media additives, binders, or wetted-material declarations are required by the buyer.

Human review
Compliance notes
This listing appears to be an industrial filter element, not a chemical substance; CAS number, purity, assay, and chemical-grade claims are not applicable unless specific filter media materials require declaration
Request wetted-material declaration for polypropylene, cotton, glass fiber, stainless steel, gaskets, end caps, adhesives, and any additives
Confirm whether the product contains activated carbon or other functional media, as the page includes inconsistent activated carbon fields marked 'up to you'
Confirm destination-market requirements such as RoHS, REACH SVHC declaration, food-contact compliance, pharmaceutical contact suitability, or potable-water approvals only where relevant to the intended use
No dangerous goods classification is expected for standard filter cartridges, but confirm DG status if media is impregnated, treated, contaminated, or shipped with chemical additives
Request HS code confirmation and export documentation before order placement
ISO9001 is a quality-management certificate, not a product-performance or regulatory approval; request current certificate copy and product test reports where needed
Avoid relying on marketplace badges as compliance evidence; obtain supplier-issued documents and, when necessary, third-party test reports
