Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as zinc hydroxide with chromate impurities
Zinc oxides/hydroxides dominate classification if chromate content is minor, per Chapter 28 purity notes.
If dispersed in vehicles for direct paint use
Prepared dispersions of pigments are chemical preparations, not pure compounds.

Import Tips & Compliance
• Specify hydration state and formula in invoices to confirm 'chromate of zinc' status
• Comply with OSHA 1910.1026 for chromate exposure during handling post-import
• Avoid bulk packaging over 25kg to minimize DOT hazmat shipping surcharges
