HS Code 36.06 – Ferro-cerium and other pyrophoric alloys in all forms; articles of combustible materials n.e.c. in chapter 36
What HS 36.06 covers
Heading 3606 serves as a residual classification for Chapter 36, encompassing "Ferro-cerium and other pyrophoric alloys in all forms; articles of combustible materials n.e.c. in chapter 36." This heading is crucial for capturing a variety of combustible items that generate heat, light, or flame but do not fit the more specific classifications for propellants (3601), prepared explosives (3602), detonators/fuses (3603), fireworks (3604), or matches (3605). The scope includes pyrophoric alloys like ferro-cerium, commonly used as flints in lighters or fire starters, which ignite spontaneously or with minimal friction in air. It also covers other prepared combustible materials not elsewhere specified, such as solid fuel tablets (e.g., hexamine), chemical firelighters, or certain liquid fuels in small containers designed for specific uses (e.g., fondue burners), provided they are not classified in other chapters like Chapter 27 (mineral fuels). Accurate classification is important for trade compliance, primarily due to flammability and transportation safety regulations. While less hazardous than explosives, these materials still require proper handling, packaging, and labeling. Misclassification could lead to incorrect safety protocols during transit or storage, and potential tariff discrepancies. This heading highlights the comprehensive nature of Chapter 36, ensuring that all significant combustible preparations are appropriately classified, even those that don't fit the primary explosive or pyrotechnic categories.
- Covers
Ferro-cerium flints, Lighter flints, Pyrophoric alloys (e.g., for fire starters), Hexamine fuel tablets, Solid fuel tablets for camping stoves, Meta fuel tablets, Solid alcohol fuels (e.g., Sterno), Chemical firelighters, Fire starting cubes, Charcoal igniters (chemical), Magnesium fire starters, Combustible novelty items not in 3604, Ignition rods for fire starting, Emergency fire starters, Survival fire starters, Gel fuels for chafing dishes, Liquid fuels in small containers (e.g., for fondue burners, n.e.c.), Fuel paste, Fire gel, Butane lighter refill gas in small non-pressurized containers (if considered combustible material n.e.c. and not elsewhere classified), Prepared tinder for fire starting, Fuel blocks, Fire starter logs (chemical).
- Examples
Millions of ferro-cerium flints are imported from China by lighter manufacturers and outdoor equipment companies worldwide, often shipped in bulk via ocean freight. Hexamine fuel tablets are exported from European manufacturers (e.g., Germany) to outdoor and camping retailers across North America and Australia, typically transported by sea or air cargo with flammability precautions. Chemical firelighters are produced in South Africa and exported to various global markets, particularly during barbecue and camping seasons, requiring adherence to dangerous goods regulations for transport.

Codes often confused with 36.06
Common mistake. A common mistake is confusing ferro-cerium flints with complete lighters (HS 9613); 3606 covers only the *pyrophoric alloy* or *fuel*, not the finished lighter. Another error involves misclassifying solid or liquid fuels found here with mineral fuels (HS 2710) or other energy products. Heading 3606 is for *prepared* combustible materials not elsewhere specified, often in specific forms like tablets or gels, distinct from bulk petroleum or gas. Additionally, some chemical firelighters might be mistakenly classified as general chemical preparations (HS 3824), but 3606 specifically covers their combustible nature and intended use.
Top exporters and importers of HS code 3606, 2025
In 2025, the largest exporter of HS code 3606 in UN Comtrade data was the Netherlands, with 15% of world exports; the largest importer in UN Comtrade data was France, with 15% of world imports. The United Kingdom reports $143M of its chapter 36 imports without product detail (confidential), so it may also belong among the top importers.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
