Import Tips
• Include refinery production records showing separation from alloy streams to validate unalloyed claim
• Monitor weight certificates closely; over-declarations can trigger audits on purity consistency
• Use inert atmosphere packaging for slabs to prevent surface oxidation mistaken for alloying
