HS-4 · Heading
3606 — Ferro-cerium and other pyrophoric alloys in all forms; articles of combustible materials n.e.c. in chapter 36
Chapter 36: Explosives; pyrotechnic products
Plain-language overview
Use HS-4 3606 when importing ferro-cerium, commonly found in lighter flints, or other pyrophoric alloys. For instance, if you're shipping a batch of lighter refills that contain liquid gas, this code is essential for proper classification.
When deciding between HS-6 360610 and HS-6 360690, consider the product's form and intended use. If your shipment consists of lighter refills in containers not exceeding 300cm³, opt for 360610. If it includes ferro-cerium in bulk or other pyrophoric alloys, 360690 is the right choice.
Pay attention to the packaging and capacity of your products. HS-6 360610 specifically targets fuels in small containers for lighters, while HS-6 360690 covers a broader range of pyrophoric alloys and combustible materials not specified elsewhere in Chapter 36.
