Import Tips

• Titration analysis must show free acid content >50% to avoid salt subheading 3402.31.10

• Classify by predominant chemical identity; minor neutralization doesn't change base acid heading

• Ensure REACH/SVHC declarations if destined for EU; common error is classifying as soap (3401)
