International shipment of sintered stone is a controlled chain of packing, container loading, sea freight, customs handoff, inland delivery and safe unloading. The material can perform well after installation yet still be vulnerable to edge impact, flexing or uncontrolled movement while it is handled as a large slab.

Quick Answer

Full sintered stone slabs are normally transported vertically on a suitable A-frame or in an engineered slab crate. The faces are separated, exposed edges are protected, the load is strapped to the frame, and the frame is blocked and restrained inside the vehicle or container against sliding and tipping.

Before dispatch, the buyer should approve the packing method, verified packed weight, container plan, document set, Incoterm responsibilities, route milestones and destination unloading equipment.

The Shipping Method Depends on What You Are Buying

Shipment Typical packing logic Main buyer concern
Full slabs Vertical A-frame or slab-specific export rack/crate Frame fit, balance, restraint, weight and unloading capacity
Cut-to-size worktops Purpose-built reinforced crate with each component supported Protection around cutouts, mitres, finished edges and labels
Samples Small parcel or sample box Product identification and courier/customs information

Do not use the same packing assumption for all three. A full slab can be supported continuously against a rack; a fabricated countertop may include large openings and finished mitres that require a different crate design.

1. Confirm the Packing System Before Booking Freight

The supplier should design the frame or crate around the slab dimensions, thickness, quantity and mass. The support surface must be large enough for the slabs; large slabs should not bear against smaller pieces or an undersized rack. Load both sides of an A-frame in a balanced sequence where the system requires it.

Ask for a packing drawing or clear packing photos. Confirm frame dimensions, slab count per frame, estimated and then verified gross weight, lifting points, edge protection, interlayers, straps and any export-wood compliance that applies to the destination.

2. Protect Faces, Edges and Corners

Surface protection prevents abrasion between slab faces, while pads or buffers at the base and uprights keep brittle edges away from direct metal contact. Corner and edge guards should sit beneath straps where necessary. Protective wrapping can keep the packed unit clean and reduce exposure during handling, but wrapping does not replace structural restraint.

Straps should secure the slabs to the frame without creating damaging point loads. The exact materials and tension belong to the packer's approved method and the product handling instructions.

3. Verify Packed Weight and Container Feasibility

Container planning is controlled by weight, balance, frame dimensions, equipment access, carrier acceptance, road limits and destination rules—not only by empty floor space. Calculate net slab weight for early planning, then use the verified packed weight for the final shipping documents and loading decision.

Do not promise a fixed number of slabs per container without reviewing thickness, frame tare weight, mixed sizes and the specific route. Our slab and packed-weight calculator is an early planning tool; the supplier and freight parties must approve the final load.

4. Block and Restrain the Frame Inside the Container or Truck

A frame that is strong enough in the warehouse can still move in transport if it is not restrained. The loading plan must prevent lateral, longitudinal, vertical and tipping movement. Blocking, shoring, airbags, friction materials and lashings are selected for the actual cargo mass and route.

The dispatch record should also include the container number, seal, package positions, verified gross weights and photos of the final blocking and restraint.

5. Separate Physical Shipping From the Incoterm

Packing describes how the slabs are protected. The Incoterm and quotation define who arranges and pays for each commercial leg and where risk transfers. These are different questions.

Confirm the commercial handoffs

  • Named origin and destination place or port
  • Export clearance responsibility
  • Ocean freight booking and surcharges
  • Cargo insurance scope and insured value
  • Destination handling, customs broker, duties and taxes
  • Container delivery, unloading, detention and return
  • Final inland transport to warehouse or site

6. Prepare the Shipping Documents and Milestones

The exact document set depends on the product, origin, destination and trade term. Common commercial documents include a commercial invoice, packing list and transport document. Wood packing, certificates, origin documents, insurance or import permits may also apply.

Track dates that can be evidenced: packing completion, verified weight, booking confirmation, cargo cutoff, loaded-on-board status, transshipment if any, arrival notice, customs release and inland delivery appointment. A vague “shipped” message is not enough to manage a project.

7. Plan Unloading Before the Container Arrives

Large slabs are heavy and can cause fatal crushing injuries if a frame or bundle shifts. The receiving site needs trained personnel, an exclusion zone, suitable lifting equipment with adequate capacity and forks or attachments that match the frame. The frame should be checked for movement and restraint before supports are removed.

Confirm access height, turning space, ground condition, equipment availability, storage racks and the person responsible for unloading. If the destination cannot receive full slabs safely, reconsider the shipment form before the order is packed.

8. Inspect and Document the Shipment on Arrival

Photograph the sealed container or vehicle, seal number where applicable, external frame condition and restraint before unloading. Record any leaning, broken straps, moisture exposure, frame damage or visible slab damage before changing the load. Follow the insurance and carrier notice procedure within the required time.

After safe unloading, verify package labels, slab count, product codes and visible condition against the packing list. Keep photos and written records even when the shipment appears sound.

How Shipping Was Planned for the Lombok Villa Kitchen Project

The real project required six full 3200 × 1600 × 12 mm slabs for two villa kitchens in Lombok. Full slabs were selected for shipment to Indonesia, with local fabrication after arrival.

The project team therefore had to treat the packing frame, full-slab dimensions, verified packed mass, route and local unloading/fabrication capability as one plan. Shipping full slabs preserved local control of final templating and cutting, but it also made destination handling readiness essential.

This is one application of the workflow above, not a universal packing or route specification. Each shipment still requires its own frame allocation, freight quotation and receiving plan.

Pre-Shipment Approval Checklist

Do not release the shipment if the supplier cannot provide the packed frame dimensions, verified gross weight, package labels, container/restraint evidence and a named destination receiver with suitable unloading equipment.
  • Final product, size, thickness, quantity and package labels
  • Frame/crate drawing or clear packing photos
  • Interlayers, edge guards, base/upright buffers and wrapping
  • Net slab weight, frame tare and verified gross weight
  • Container and restraint plan approved for the route
  • Incoterm with named place and written scope
  • Document list, insurance and customs responsibilities
  • Destination equipment, crew, access and storage ready
  • Arrival inspection and damage-notice procedure assigned

The Bottom Line

Do not release full slabs until the packed dimensions and gross weight, frame protection, container restraint, shipping scope, document owners and destination unloading equipment are confirmed.

Confirm Packing and Unloading Before Dispatch

Share the slab size, thickness, quantity, destination and required trade term. We can review the A-frame allocation, packed weight, freight scope and destination handoff.

International Sintered Stone Shipping

01

Why are full sintered stone slabs shipped on A-frames?

A suitable A-frame supports large slabs vertically and provides a structure for balanced loading, lifting and restraint. The frame must still be secured against movement inside the vehicle or container.

02

Is it better to ship full slabs or fabricated countertops?

Ship full slabs when qualified local fabrication and handling are available. Fabricated components need shop-drawing approval and purpose-built crates that protect openings, mitres and finished edges.

03

What should I confirm before the shipment leaves?

Confirm the frame or crate, slab and package labels, verified gross weight, container and restraint plan, Incoterm scope, document list, route milestones and destination unloading plan.

04

How should full slabs be received safely?

Use trained personnel, a controlled exclusion zone, level ground and mechanical equipment rated for the packed frame. Inspect the restraints and load condition before removing any support.

05

What should I record if slabs arrive damaged?

Photograph the sealed container or vehicle, restraints, frame, labels and damage before changing the load. Notify the carrier, insurer and supplier within the required claim period.
