What is carbonyl dichloride used for?

Carbonyl dichloride, or phosgene, is primarily used in the production of isocyanates, which are key components in making polyurethanes.

How do I classify phosphorus oxychloride?

Phosphorus oxychloride falls under **HS-6 281212** and is used mainly in the manufacture of organophosphorus compounds.

What distinguishes sulphur monochloride from sulphur dichloride?

Sulphur monochloride is used for synthesizing sulfur compounds, while sulphur dichloride is a chlorinating agent in organic synthesis.

What is the HS code for arsenic trichloride?

Arsenic trichloride is classified under **HS-6 281219**, which also includes other chlorides and chloride oxides not specifically listed.

Are there any special regulations for importing halides?

Yes, many halides, especially toxic ones like phosgene, are subject to strict regulations and may require special permits for import.

HS-4 · Heading

2812 — Halides and halide oxides of non-metals

Chapter 28: Inorganic chemicals

Plain-language overview

Use HS-4 2812 when importing halides and halide oxides of non-metals, such as carbonyl dichloride (phosgene) or phosphorus oxychloride. These substances are often used in chemical manufacturing and pharmaceuticals, making proper classification essential for compliance and duty assessment.

To distinguish between the HS-6 lines, consider the specific chemical properties and applications. For example, 281211 is for carbonyl dichloride, a toxic gas used in organic synthesis, while 281213 covers phosphorus trichloride, commonly utilized in producing pesticides and flame retardants. Accurate classification helps avoid penalties and ensures smooth customs clearance.

When deciding between 281215 (sulphur monochloride) and 281216 (sulphur dichloride), note that the former is primarily used in the synthesis of sulfur compounds, while the latter is used in organic synthesis and as a chlorinating agent. Understanding these distinctions is crucial for selecting the correct subheading.
