Import Tips

• Include lab analysis showing osmium >2% and no predominant other PGMs for classification

• Avoid common error of declaring as powder; sponge is unwrought if not sieved to 0.5mm spec

• Use specialized packaging to prevent oxidation; declare HS correctly to evade anti-dumping scrutiny
