What is the HS Code for Polyformaldehyde?

The primary HS code for polyformaldehyde is 3907.10. This code falls under Chapter 39 for plastics and ensures proper tariff classification in international trade.

Polyformaldehyde, also known as POM or polyacetal, requires precise HS code use for customs clearance worldwide.

Polyformaldehyde Material Properties and Uses

Polyformaldehyde offers exceptional strength and low friction. As a thermoplastic, it polymerizes from formaldehyde for high-performance applications.

  • Superior rigidity and stiffness.
  • Excellent chemical and wear resistance.
  • Ideal for precision engineering parts.
  • Low moisture absorption.
  • High dimensional stability.

Breakdown of HS Code 3907.10 Structure 2025

HS code 3907.10 breaks down into clear hierarchical levels. Understanding this structure aids accurate classification.

  1. Chapter 39: Plastics and articles thereof.
  2. Heading 3907: Polyacetals, other polyethers, epoxide resins.
  3. Subheading 3907.10: Polyacetals (polyformaldehyde specifically).

In 2025, this remains stable per WCO guidelines.

2025 Regional HS Code Changes for Polyformaldehyde

Several regions update HS code applications in 2025. These affect polyformaldehyde shipments significantly.

  • US: Full HTS enforcement ends de minimis exemptions.
  • GCC: Mandatory 12-digit extensions for local tariffs.
