Import Tips
• Certify block density >1.75 g/cm³ and purity >99% carbon; document prevents reclassification as lower-grade carbon
• Provide dimensional tolerances and machining allowance specs; CBP may require proof of semi-manufactured status
• Avoid combining with finished electrodes in same shipment to prevent set classification under 8545
