NAICS codes like sector 33 are used for domestic industry classification, economic reporting, and trade statistics aggregation — not for determining import duties. Tariff classification for customs purposes is governed by the Harmonized Tariff Schedule (HTS), and a single NAICS sector can correspond to dozens of HTS chapters. Trade professionals use NAICS-level data for market analysis and industry benchmarking, then drill down to HTS codes for actual duty and compliance determinations.
Primary metals (NAICS 331) and fabricated metal products (NAICS 332) have historically seen the most active antidumping, countervailing duty, and Section 232 trade-remedy activity. Steel and aluminum products in particular are subject to broad Section 232 tariffs, and numerous antidumping orders cover specific metal product forms. Importers in these subsectors should conduct order-scope reviews at the HTS line level before procurement.
