How importers and project buyers can turn a concept plan into a controlled quotation and production release

| Meta description | Work with a custom expandable container house manufacturer in China using a controlled process for requirements, drawings, quotation, changes, production and inspection. |
| Evidence status | The process aligns with Xutuo’s public OEM/ODM and service pages but avoids promising a universal lead time, deposit, approval or customization range. |
Customization Needs a Controlled Baseline
A custom expandable container house project can change bedroom count, openings, interior finishes, wet areas, services and external appearance. Each change can affect structure, weatherproofing, transport, cost and approval evidence. The buyer should therefore create one approved baseline before production rather than relying on chat messages, annotated photos or an undated floor plan.
Xutuo House lists the XT-EH007 as an OEM/ODM Customized Expandable Container House Mobile Home. Its service page describes a sequence of requirements, quotation, order terms, confirmation of customization, production, delivery and installation. Exact commercial terms, schedule and technical deliverables should be confirmed in the signed order.
1. Requirements Brief
- Country, site and intended use
- Occupancy and room schedule
- Target external dimensions and transport constraints
- Climate and project design criteria supplied by the responsible team
- Kitchen, bathroom, electrical, plumbing and HVAC scope
- Interior and exterior finish level
- Required drawings, calculations, records and inspections
- Quantity, batches, destination and target program
2. Concept and Technical Drawings
Approve the concept only after checking furniture, doors, circulation, wet areas and utility routes. The technical set should use a drawing number, revision, date and approval status. It should coordinate architectural dimensions, openings, structural interfaces, foundation and anchoring information, electrical and plumbing layouts, finishes and package data appropriate to the order.
3. Comparable Quotation
The quotation should name the drawing revision and attach an inclusion/exclusion schedule. Separate the base model, custom changes, options, documentation, inspection, packing and logistics. Record currency, Incoterm, named place, validity, payment milestones and how changes are valued.
4. Change-Control Procedure
- Buyer or supplier raises a numbered change request.
- The affected drawings and schedules are identified.
- Technical, price, timing, packing and documentation impacts are assessed.
- Authorized representatives approve or reject the change in writing.
- The drawing register and quotation are updated before work proceeds.
- Factory inspection uses the latest approved revision only.
5. Production Release and Inspection
Do not release production while key rooms, openings, services or finishes remain undecided. Agree material approval records, sample or mock-up needs, inspection stages, hold points, non-conformance handling and final release documents. A physical sample unit can be useful for larger programs, but whether one is required, how it is priced and how changes are incorporated is order-specific.
Frequently Asked Questions
Does OEM/ODM mean every request is feasible?
No. Feasibility depends on structure, folding mechanism, transport, services, documents, cost and the destination requirements.
What document should control production?
The contract should identify the approved drawing and schedule revisions that form the production baseline.
| Commercial boundary: the Xutuo service page contains general process statements, but the signed quotation and contract should control the actual deposit, lead time, scope, inspection and delivery terms. |
Minimum Drawing Register Fields
For each document, record the document number, title, revision, issue date, originator, purpose of issue, approval status and superseded revision. Include floor plans, elevations, sections, structural interfaces, foundation and anchoring information, electrical and plumbing layouts, finish schedules, packing drawings and installation instructions. The buyer and supplier should use the same register.
At production release, issue a signed or otherwise controlled record showing which revisions are approved. At final inspection, compare the finished unit with that baseline and collect as-built changes. This creates a traceable route from request to quotation, production, inspection, shipment and site handover.
