Key Points for Export Packaging

Products must be systematically stacked, utilizing interlayer protective materials to avert paint scratching and deformation.
The base should be secured on a fumigated solid wood pallet, while the exterior requires encasement in waterproof stretch film to ensure a sealed and damp-proof environment.
Detached accessories need individual tagging prior to collective packaging. We facilitate both containerized maritime shipping and transnational land carriage.
External packaging must distinctly indicate specifications, weight, and origin, and enclose a certificate of conformity, quality test report, and packing list, adhering to global trade shipping regulations.
