Import Tips & Compliance
• Distinguish 'crushed' from 'powdered' via particle analysis; retain lab sieve tests showing irregular sizing
• Density declarations critical for freight classing; under申报 risks audit penalties
• Eco-certifications boost value—declare if sustainably mined to access green import lanes
