Cargo Worthy(CW)与Wind & Water Tight(WWT)集装箱对比:结构标准、认证、状态以及哪种等级适合存储、出口或转售用途的完整选择参考。
Compare Cargo Worthy and Wind & Watertight shipping containers — inspection criteria, transport eligibility, storage suitability and US pricing.
Cargo Worthy (CW)
Structurally sound, watertight, valid CSC plate. Eligible for ocean export, intermodal rail and SOC one-way leasing. The grade exporters and freight forwarders buy.
Wind & Watertight (WWT)
Weatherproof and dry, but typically without a valid CSC plate. Restricted to over-the-road moves and on-site storage. Costs $400–$1,200 less per unit than CW.
How to Choose
CW for any unit that will ship by sea, cross borders or be resold. WWT for stationary US storage where the CSC plate has no operational value.
