Shipping Container House Company: Buyer Questions Answered | DECHEN PACKAGING · 3

What should I confirm before requesting a quotation?

Define the project use, occupancy, floor plan, destination climate, local utility standard, transport limits, and installation scope. Provide these inputs to the supplier so the quotation is based on the same requirements. Ask the supplier to list what is included and excluded, such as foundation, unloading, and utility connections.

How do I compare quotations from different suppliers?

Normalize the scope of supply. Ask each supplier to break down the unit price, packing, delivery, and installation support. Confirm the Incoterms, currency, and whether drawings and documents are included. Use a checklist that covers structure, panels, insulation, doors, windows, electrical, plumbing, finish, and transport. Do not compare a complete unit with a shell-only offer.

What does sample approval involve?

Sample approval means confirming the exact materials and components that will be used in bulk production. This can be a physical sample room, material samples, or a pre-production unit inspection. Document the approved sample with photos, specifications, and a signed checklist. For folding container houses, ask for a demonstration of the folding and unfolding process and the sealing details at the hinges.

Which quality control documents should I request?

Request the inspection plan covering incoming materials, frame welding, panel assembly, insulation, waterproofing, door and window installation, utility testing, and packing. Ask for inspection checklists and photos. If third-party inspection is required, clarify who arranges it and who bears the cost. A written corrective action procedure is more useful than verbal assurances.

How do I confirm insulation and climate suitability?

Ask for the insulation material, density, thickness, and placement for walls, roof, and floor. Confirm how thermal bridging at frame connections is treated. For hot or humid climates, discuss ventilation and moisture control. For cold climates, confirm heating provisions and door and window performance. These details should appear in the drawings and specifications.

What should I check in the electrical and plumbing configuration?

Confirm voltage, frequency, outlet types, wiring standard, lighting, and distribution board. For plumbing, confirm water supply, drainage, fixture types, pipe materials, and venting. Match these to local utility standards. If the supplier provides fixtures, confirm their specifications and local spare parts availability.

How are shipping and loading handled?

Ask for the packing method, loading plan, and packing list with dimensions and weights. Confirm the delivery point and who handles unloading. For flat-packed or folding units, verify that packing protects panels, frames, and finishes. Check site access for the delivery vehicle and lifting equipment before shipment.

What installation support is typically available?

Installation support can range from an instruction manual to remote guidance or on-site supervision. Clarify what is included and what the buyer must provide, such as labor, tools, power, water, and foundation. Foundation design and utility connections are typically confirmed by local professionals. Ask the supplier for foundation interface drawings and an installation manual before production.
