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
Outdoor-grade PP and PE additive packages where HALS performance is required
Polyolefin film, tape, fiber, rotational molding and injection molding formulations
Masterbatch production requiring polymeric low-volatility light stabilizer input
Plastic compounding projects that combine HALS with antioxidants or UV absorbers after formulation validation
Distributor stock item for UV stabilizer and plastic auxiliary additive portfolios
How we compare
Sourcing options
25 kg carton trial order for specification confirmation
Palletized carton shipment for distributor or plant stock
FOB Shanghai quotation for buyer-controlled freight
CIF or CFR quotation for destination port comparison
Sample request with COA and SDS review before commercial order
Pre-shipment inspection or third-party lab test for larger lots
Customized labeling and packing subject to supplier confirmation
Human review
Compliance notes
Request current COA, SDS, TDS, specification sheet and product label draft before purchase
Confirm CAS 65447-77-0 identity and any polymeric composition details needed for customs or inventory review
Supplier page lists REACH certification; buyer should request supporting documentation and verify coverage for the intended importer, tonnage band and use
Confirm HS code, country of origin certificate availability, and export invoice/packing list format
Check dangerous goods classification with the supplier’s SDS and freight forwarder before shipment; do not assume non-DG status from marketplace text
Confirm whether product contains restricted impurities, residual monomers, heavy metals, SVHCs or other declarable substances relevant to destination market
For food-contact, medical, toy, automotive or electrical applications, request application-specific declarations rather than relying on general additive claims
No regulatory guarantee is implied; importer remains responsible for destination-country chemical registration, customs clearance and end-use compliance
