How do you ensure moisture protection during sea freight?

An aluminum foil moisture barrier or PE inner liner can be added. Desiccants are placed inside the container. A fumigation certificate is provided if wooden pallets are used.

What if there is poor sealing or bag breakage?

100% factory testing is conducted. We offer free replacement or concession acceptance for quality issues, along with video guidance.
