HS Code for Diphenylamine

Introduction

In the complex world of international trade, understanding HS codes is crucial for smooth customs clearance and compliance. Today, we'll delve into the HS code for diphenylamine (DPA), an important chemical compound used in various industries. As a digital logistics platform, FreightAmigo is committed to helping our clients navigate the intricacies of global shipping, including the proper classification of chemicals like DPA.

What is Diphenylamine?

Diphenylamine (DPA) is an organic compound with the chemical formula (C6H5)2NH. It is a colorless solid that is widely used in industrial applications, particularly as an antioxidant and stabilizer. Some key points about DPA include:

• Chemical name: N-Phenylaniline
• Molecular formula: C12H11N
• Appearance: Colorless to amber crystals or flakes
• Melting point: 52-54°C (126-129°F)
• Boiling point: 302°C (576°F)

Common Uses of Diphenylamine

DPA serves several important functions across various industries:

1. Antioxidant: DPA is widely used as an antioxidant in the rubber and polymer industries. It helps prevent degradation of materials caused by oxidation, extending the lifespan of products.
2. Rubber stabilizer: In rubber manufacturing, DPA acts as a stabilizer, improving the durability and performance of rubber products.
3. Agricultural applications: DPA is used to prevent scald (a browning disorder) in apples and pears during storage.
4. Analytical reagent: In chemical analysis, DPA is used as a reagent for detecting nitrates, nitrites, and other oxidizing agents.
5. Dye intermediate: DPA serves as an intermediate in the production of various dyes.

HS Code for Diphenylamine

The Harmonized System (HS) code for diphenylamine is:

2921.44

This code falls under Chapter 29 of the HS, which covers "Organic chemicals". Let's break down the classification:

• 29: Organic chemicals
• 21: Amine-function compounds
• 44: Diphenylamine and its derivatives; salts thereof

It's important to note that while this is the general HS code for diphenylamine, some countries may have additional digits for more specific classification. Always verify the exact code required for your specific shipment and destination.

Importance of Correct HS Code Classification

Proper classification of chemicals like DPA using the correct HS code is crucial for several reasons:

1. Customs compliance: Accurate HS codes ensure compliance with customs regulations and help avoid delays or penalties.
2. Duty and tax determination: HS codes are used to calculate import duties and taxes, affecting the overall cost of shipping.
3. Trade statistics: Correct classification contributes to accurate international trade statistics.
4. Safety and security: Proper identification of chemicals is essential for handling and transportation safety.
5. Trade agreements: HS codes may affect eligibility for preferential treatment under various trade agreements.

Challenges in Classifying Chemicals

Classifying chemicals like diphenylamine can be challenging due to several factors:

• Complex chemical structures and compositions
• Multiple potential uses of a single chemical
• Variations in classification between countries
• Regular updates to HS codes and classifications

These challenges underscore the importance of working with experienced logistics partners who understand the nuances of chemical classification and international shipping regulations.
