Chapter 99 classification notes
Chapter 99 contains country-specific temporary tariff provisions including Section 232 / 301 surcharges. US Chapter 99 currently lists active Section 301 China tariffs across 7,000+ HS lines.
Frequent misclassification in this chapter
Items subject to Section 301 surcharges still require their substantive HS classification AND a Chapter 99 statistical reporting line.
