Import Tips

• Verify zinc dust certification showing at least 85% metallic zinc and 80% of particles passing 63-micron sieve per Chapter 79 note (c)

• Provide lab analysis reports during customs clearance to distinguish from zinc powders; misclassification as powder leads to rejection

• Check for REACH compliance if importing to EU markets, as zinc dust is regulated for environmental release
