Key standards depend on your target market but often include ISO, ASTM, CE, or regional certifications such as REACH (Europe) or BIS (India). Ensure PVC tubes meet fire safety, mechanical strength, and chemical resistance requirements pertinent to your application. Certification of compliance with RoHS or other environmental directives can also be critical, especially in European markets. Request suppliers to provide test reports, product datasheets, and third-party inspection certificates. Verifying compliance minimizes legal and safety risks, ensures product durability, and facilitates smooth customs clearance.
