What is Triethylenediamine Catalyst?

Triethylenediamine, or TEDA, accelerates polyurethane reactions. Also called 1,4-diazabicyclooctane (DABCO), it's a heterocyclic amine vital for foam manufacturing.

• Promotes isocyanate-polyol reactions
• Used in flexible and rigid foams
• Improves foam curing speed
• Critical in automotive and construction applications
• Stable under 2025 production standards

Official 2025 HS Code for Triethylenediamine Catalyst

The precise HS code for triethylenediamine catalyst is 2933.59. This places it in Chapter 29 for organic chemicals.

Confirm with local customs for national tariff variations in 2025.

Why HS Code Classification Matters in 2025

Correct HS codes reduce duties 10% on average. In 2025, enhanced enforcement amplifies the need for precision.

• Avoids customs penalties and seizures
• Qualifies for trade agreement benefits
• Streamlines supply chain logistics
• Supports accurate trade data reporting
• Prevents shipment rejections

Common Classification Challenges for Chemical Catalysts

Chemical structures often lead to HS code disputes. Triethylenediamine's dual ring system confuses classifiers in 2025.

• Multiple potential HS headings
• Evolving purity standards
• Mixture vs. pure compound debates
• Country-specific interpretations
• 2025 WCO explanatory note updates
