Packaging Of Howo Differential

All Genuine Howo Differentials adopt standardized layered protective packaging tailored to the product structure and mechanical component characteristics.
Each finished differential assembly is individually wrapped with shockproof foam, anti-rust paper and waterproof plastic film, effectively protecting the differential housing, gear sets, cross shaft and locking mechanism from extrusion deformation, surface abrasion, rust and moisture damage.
All products are neatly packaged in thickened high-strength export cartons or fumigated wooden cases, preventing collision, gear displacement and structural damage during long-distance ocean transportation and prolonged warehouse storage.
Supporting accessories such as adjusting shims, fixing bolts and sealing gaskets are independently sealed and packaged to ensure complete sets and zero loss during delivery.
Each outer package is clearly printed with OEM part numbers, applicable axle models, product specifications, quantities and standard shipping marks, supporting fast cargo inspection and smooth customs clearance for global shipments.
