Last updated: July 2026 dataFerrocerium — the iron-cerium alloy that generates sparks when struck — is the active element in lighter flints, fire-starting rods, and related ignition devices, all of which fall under this heading alongside other articles of specified combustible materials. China dominates US import supply, with Israel and Ireland also notable sources. The US schedule breaks the heading into ferrocerium and other pyrophoric alloys (3606903000) and combustible-material articles not elsewhere specified (3606908000), with a legacy consolidated line (3606900000) also present. Importers should note that China-origin goods in this heading are subject to Section 301 tariffs, making supplier diversification a live cost consideration.
