How to Verify ISO 9001-Certified Container House Suppliers: A Step-by-Step Guide ISO 9001 is a "pass" for suppliers' quality capabilities, especially in customized fields such as container houses. Certification can greatly reduce cooperation risks! If you’re new to sourcing container houses or prefab buildings, verifying ISO 9001-certified suppliers ensures quality, reliability, and compliance with international standards. Below is a clear, step-by-step process to help you confirm a supplier’s credibility.   Step 1: Ask for Certification Documents Request their ISO 9001 certificate and cross-check details (issuing body, validity date, and scope). Generally, suppliers will have this certificate. If they don’t even have this certificate, then there is no need for you to cooperate with them.   Step 2：Verify Online First determine which country the supplier is from, then find the certification body’s website for confirmation (e.g., TÜV, SGS, or Bureau Veritas). If your suppliers are from China, you can check it on the official website of the China Certification and Accreditation Administration.

As you know, the validity period of ISO is 3 years.   Kind tips If you decide to work with or buy from a manufacturer, it’s always a good idea to visit their factory so you can see firsthand their quality control processes (e.g., welding standards for container house manufacturers);  whether they use certified materials (e.g., corrosion-resistant steel, insulation panels);  whether they follow safety protocols;  ask about their capacity: make sure they can handle the size of your project (e.g., a large prefabricated apartment building vs. a small container restaurant). Ask past clients who have ordered similar projects (e.g., container home business owners or modular prefab home developers);  check out their work to see if there are any success stories in your industry (e.g., container coffee shop construction or expandable cabin installation)，etc. Only by visiting the factory down to earth can you better understand the supplier, which will be more conducive to your future business and cooperation.
