Import Tips
• Include fired ceramic composition analysis showing clay/silica content to distinguish from Chapter 68 millstones
• Document void percentage in brick structure as key evidence for hollow insulating classification
• Avoid bulk packaging over pallets as loose loading risks damage claims during ocean freight
