Glass is a high-density, fragile cargo. Ensure the supplier uses heavy-duty containers and proper internal bracing to prevent the crates from shifting. For shipping to countries with strict environmental or wood packaging regulations (like the US, AU, or EU), ensure all wooden crates are ISPM 15 certified (heat-treated). It is highly recommended to purchase All-Risk Marine Insurance, which typically costs only 0.1% - 0.3% of the invoice value but provides essential protection against maritime accidents.
