What quality assurance certifications should I look for?
Look for suppliers with relevant quality assurance certifications, such as ISO 9001 for quality management systems and ISO 14001 for environmental management. Additionally, check for compliance with ASTM standards, particularly ASTM A240 for stainless steel sheets and plates. Request material test reports (MTRs) to confirm the properties and chemical composition of the stainless steel 18-8 being supplied. This documentation is essential for ensuring that the materials meet your specifications. -
How can I manage logistics when sourcing stainless steel 18-8 internationally?
Managing logistics involves understanding shipping options and costs, customs regulations, and delivery timelines.

Engaging a freight forwarder can simplify the process and help navigate international shipping complexities. -
What should I do if there is a dispute with my supplier?
In the event of a dispute, first, attempt to resolve the issue through direct communication with the supplier. Document all correspondence related to the problem.
