Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-mixed into synthetic organic tanning preparations
When incorporated into tanning extracts or preparations, it shifts from pure salt to Chapter 32 tanning products.
If complexed with borates or other acids
Complex salts involving multiple acid radicals are classified under 2833 per Chapter 28 notes on double salts.
If blended into animal fertilizers
Fertilizer mixtures containing chromates fall under Chapter 31, excluded from Chapter 28 by note 3.

Import Tips & Compliance
• Declare exact purity level and end-use (e.g
• tanning) to avoid reclassification; provide supplier specs
• Comply with REACH-like TSCA regulations; pre-register with EPA for chromate imports over certain volumes
• Package in UN-approved drums for oxidizer Class 5.1; common pitfall is insufficient spill containment plans
