HS Code for Hypophosphorous Acid

Introduction to Hypophosphorous Acid and Its HS Code

Hypophosphorous acid, also known as phosphinic acid, is an important chemical compound used in various industrial applications. As a reducing agent and key ingredient in chemical synthesis, it plays a crucial role in many manufacturing processes. For international trade and customs purposes, hypophosphorous acid is classified under a specific Harmonized System (HS) code. In this article, we'll explore the HS code for hypophosphorous acid and discuss its significance in global trade.

What is the HS Code for Hypophosphorous Acid?

The HS code for hypophosphorous acid is 2811.19. This code falls under Chapter 28 of the Harmonized System, which covers "Inorganic chemicals; organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes".

Breaking down the HS code 2811.19:

• 28: Chapter 28 - Inorganic chemicals
• 11: Heading - Other inorganic acids and other inorganic oxygen compounds of nonmetals
• 19: Subheading - Other

Understanding the HS Code System

The Harmonized System is an international nomenclature developed by the World Customs Organization (WCO) for the classification of goods. It forms the basis for customs tariffs and international trade statistics in over 200 countries. The system uses a six-digit code to identify products, allowing for a standardized classification across borders.

Importance of Correct HS Code Classification

Accurate HS code classification is crucial for several reasons:

• Determining applicable customs duties and taxes
• Ensuring compliance with import/export regulations
• Facilitating smooth customs clearance processes
• Enabling accurate trade statistics

For chemicals like hypophosphorous acid, precise classification is particularly important due to potential safety and regulatory considerations.

• Density: 1.493 g/cm³
• Melting point: 26.5°C (79.7°F)
• Boiling point: 130°C (266°F)

Applications of Hypophosphorous Acid

Hypophosphorous acid finds applications in various industries due to its unique properties:

1. As a Reducing Agent

One of the primary uses of hypophosphorous acid is as a reducing agent in chemical reactions. Its strong reducing properties make it valuable in processes where the removal of oxygen or the addition of hydrogen is required.

2. In Chemical Synthesis

Hypophosphorous acid plays a crucial role in the synthesis of various organic and inorganic compounds. It is used in the production of pharmaceuticals, agrochemicals, and other specialty chemicals.

3. Electroless Plating

The compound is widely used in electroless nickel plating processes, where it acts as a reducing agent to deposit nickel onto surfaces without the need for an electric current.

4. Water Treatment

In water treatment applications, hypophosphorous acid can be used to remove dissolved oxygen and prevent corrosion in boiler systems and other industrial water circuits.

5. Polymer Industry

Hypophosphorous acid is used as a polymerization initiator and chain transfer agent in certain polymer production processes.

Trade Considerations for Hypophosphorous Acid

When importing or exporting hypophosphorous acid, several factors need to be considered:

Safety and Handling

As a corrosive and reducing agent, proper safety measures must be in place during transportation and storage. This includes using appropriate containers and following relevant dangerous goods regulations.

Purity and Concentration

The concentration of hypophosphorous acid can vary, typically ranging from 30% to 50%. The specific concentration may affect its classification and associated regulations.

Documentation

Proper documentation, including safety data sheets (SDS) and certificates of analysis, should accompany shipments of hypophosphorous acid.

Regulatory Compliance

Importers and exporters must comply with relevant chemical control regulations, which may vary by country or region.
