Review Compliance Records
Operational standards

Technical resin supply governance

XIANTONG pairs verified Chinese polymer compounding facilities with international compliance auditing. We eliminate procurement friction by qualifying resin grades against verifiable processing parameters and formal laboratory data sheets.

Supply infrastructure

Tianjin logistics coordination

Operating from the Tianjin Port Free Trade Zone, our materials desk coordinates resin procurement across accredited chemical manufacturing clusters. We oversee application-specific compounding for converters running blown film, thermoforming, and injection tooling.

Our technical coordinators review raw melt flow index specs, moisture limits, and additive dispersion metrics prior to dispatch. Material consignments ship with lot-specific certificates of analysis and retained production samples.

Regulatory policy

Physical laboratory testing supersedes marketing assertions.

Every compostability metric, bio-based percentage, and barrier specification we quote corresponds to accredited standard documentation under EN 13432, ASTM D6400, or ISO 17088. Unverified commercial claims are barred from our material catalogs.
