Bathroom cabinets are bulky and fragile. To optimize costs, choose RTA (Ready-to-Assemble) packaging, which can reduce shipping volume by up to 60% compared to pre-assembled units. However, for luxury markets, fully assembled units are preferred to save on local labor. Ensure the packaging meets ISTA 3A or 6-Amazon.com standards, utilizing 5-layer corrugated cartons, high-density foam corner protectors, and honeycomb board padding. For ceramic basins, wooden crates or palletization is highly recommended to prevent cracking during sea freight.
