Import Tips

• Provide detailed technical brochures showing numerical control features and grinding wheel specifications during customs entry

• Label equipment clearly as 'cylindrical grinder for metals' to distinguish from polishing-only machines potentially in 8460.39

• For high-value imports, consider binding rulings from CBP on classification to mitigate risks in semiconductor-adjacent industries
