Import Tips
• Document as 'double chromate salt' to justify 2841 over general potassium chromates in 2841.90.10
• Include REACH Annex XVII compliance for EU-sourced goods due to chromate restrictions
• Test for heavy metal content to prevent reclassification as hazardous waste (Chapter 38 mixtures)
