01
What product or material documents may be required for importing modular houses?
Requirements differ by country, building use and tender specification. Documents may concern materials, performance testing or other compliance matters. Provide the destination and required-document list during inquiry so that available records can be reviewed; not all certifications apply to every product.

02
Who is responsible for local building approvals and structural calculations?
Local approvals are generally handled by qualified designers or contractors under the destination’s regulations. The product supplier may provide drawings, specifications and material records within the agreed scope. Any locally licensed engineer review or special calculations should be assigned before the project begins.

03
How is a cleanroom classification tested and confirmed?
Cleanroom classification is established through testing, including airborne particle concentration under defined operating conditions and an applicable standard. Airflow, pressure and recovery tests may also be required. Qualified specialists should follow the agreed validation plan.

04
What details should be checked in a cleanroom panel test report?
Check the product designation, tested construction, standard, test scope, report date and applicability. Findings for one construction or sample may not automatically apply to another. Confirm that documents match the actual supplied specification.

05
Do cleanroom doors and FFUs always require CE documentation?
The need for CE marking or other compliance documents depends on the product category, destination market and applicable rules. Not every cleanroom component follows the same route. Share the destination country and exact models so the relevant requirements and available documents can be checked.
