A shipment can have perfect stone and still arrive damaged if the packaging was wrong. In 18 years of exporting marble, granite, sandstone, limestone, slate and quartzite from Udaipur, the claims we’ve had to deal with almost always trace back to packaging, not the stone itself — crates that weren’t waterproof, foam that wasn’t thick enough, or documentation that didn’t match what customs expected. This is the packaging and loading process we follow on every container, and what you should verify before yours ships.
Natural stone slabs are heavy but brittle along their edges and corners, which is where most transit damage happens. Crates need to hold slabs rigidly in place through weeks of sea transit, ocean humidity, and handling at multiple ports. Foam-lined, waterproof wooden crates are the industry standard for a reason — they absorb vibration and protect against moisture ingress, which untreated cardboard or thin plywood packaging cannot do. If a supplier quotes a noticeably lower price, ask specifically what packaging is included, since this is a common place costs get cut.
ISPM15 is the international standard requiring wood packaging material to be heat-treated or fumigated to prevent the spread of pests across borders. Most countries, including the US, EU members, Australia and the UK, will hold or reject shipments with non-compliant wooden crates at customs. Every crate should carry the ISPM15 stamp, and your supplier should be able to provide treatment certification on request. This is a simple thing to verify before shipment and an expensive thing to discover is missing after your container has already left port.
Slabs are packed upright in custom-built wooden crates, separated by foam padding to prevent surface-to-surface contact, and braced internally so they can’t shift during transit. Tiles are boxed and palletised, with corner protection on pallet edges. Each crate or pallet is labelled with stone name, quantity, dimensions and weight, matching the packing list exactly — mismatches here are one of the most common causes of customs delays, since inspectors flag any discrepancy between the physical label and the paperwork.
Since the standard minimum order is 20 metric tonnes, roughly one 20ft container, buyers who don’t need a full container of one variety often combine multiple stones — for example marble slabs from our Indian marble exporter range alongside granite tiles — to reach that minimum. Loading order matters here too: heavier crates go at the base and centre of the container, with weight distributed evenly to avoid shifting at sea.
Ask for photos of the container loading itself, not just the finished crates — this confirms bracing and weight distribution were done correctly. Confirm the ISPM15 stamp is visible in the photos. Check that the packing list quantities match what you ordered before the container is sealed, since corrections after sealing mean re-opening the container at port, which costs time and money on both sides.

Yes, combining stone types is common when a buyer doesn’t need a full container of one variety, and it’s the standard way to meet the 20 metric tonne minimum order.
Ask for loading photos showing bracing, weight distribution and the ISPM15 stamp, and confirm the packing list matches your order exactly before sealing.
Most claims trace back to inadequate packaging — thin or non-waterproof crates, insufficient foam padding, or poor bracing — rather than defects in the stone itself.
