Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contaminated or containing more than 1% impurities
Impure potassium dichromate exceeding purity thresholds falls under other chemically defined salts of inorganic acids in 2829.90.
If imported as a formulated solution or mixture for retail
Prepared chemical mixtures or lab reagents not purely chemically defined are classified in Chapter 38 as chemical preparations.
If other dichromates like sodium dichromate
Heading 2841.50 covers all dichromates except potassium specifically; other metal salts go to the 'other' subheading.

Import Tips & Compliance
• Verify chemical purity and provide Certificate of Analysis (CoA) to confirm it meets 'chemically defined' criteria under Chapter 28 Note 1
• Include Safety Data Sheet (SDS) highlighting toxicity and oxidizing properties for DOT and EPA compliance during import
• Avoid misclassification as a mixture; ensure labeling specifies 'potassium dichromate' to prevent scrutiny under hazardous materials regs
