HS Code for Cobalt Nitrate 2025 Guide

TL;DR: The **HS code for cobalt nitrate is 2834.29** in 2025. This guide covers classification steps, 2025 regional updates, shipping best practices, and tools for accurate tariff compliance in global trade.

What is the HS Code for Cobalt Nitrate?

The HS code for cobalt nitrate is 2834.29 worldwide. This six-digit code falls under Chapter 28 for inorganic chemicals.

Cobalt nitrate (Co(NO3)2·6H2O) is a red crystalline compound used in catalysts, pigments, and ceramics.

  • Water-soluble hydrate form.
  • Essential for oxidation processes.
  • Common in lab reagents.
  • Key ingredient in blue ceramic pigments.
  • Stable classification since 2017 HS update.

How HS Codes Work for Chemical Classification

HS codes standardize product classification globally through WCO guidelines. The Harmonized System uses a hierarchical structure.

Chapter 28 covers inorganic chemicals like nitrates. Nations extend beyond six digits for tariffs.

  • Chapter: 2 digits (28 = inorganic chemicals).
  • Heading: 4 digits (2834 = nitrites; nitrates).
  • Subheading: 6 digits (2834.29 = other nitrates).
  • Tariff codes: 8-12 digits (country-specific).
  • Updated every 5 years by WCO.
