How to Verify the Supplier\u2019s Legitimacy and Capability?<\/h2>\n

A fancy Alibaba page doesn't guarantee reliability. You need real-world checks\u2014especially before bulk orders.<\/p>\n

The first step is requesting their business license, production certificates, and references from existing overseas clients.<\/p>\n

You should start by checking certifications like ISO 9001. If you're in the food or medical sectors, FDA, REACH, or RoHS matters too. For instance, our silicone O-rings<\/a> are food-grade and safe for direct contact.<\/p>\n

Never place a bulk order without samples. Ask for several materials\u2014NBR, EPDM, FKM\u2014and test under your real-world conditions. A video call or factory virtual tour can go a long way toward validating operations. And if they hesitate? That\u2019s your red flag.<\/p>\n

Check their existing client base. Do they work only locally or do they export? International experience usually means better documentation and communication.<\/p>\n
