About HS Code 381800

This category covers highly specialized chemical elements and compounds that have been 'doped' for use in electronics, typically in the form of discs, wafers, or similar shapes. These materials, most commonly silicon or germanium, are intentionally modified with impurities to alter their electrical conductivity, making them fundamental building blocks for semiconductors and microchips. Importers and exporters are primarily semiconductor manufacturers, electronics companies, and specialized material suppliers. The trade involves high-value, high-precision products that are critical for the global electronics industry, with stringent quality control and purity requirements being paramount for device performance.

Products Under This Code

Doped silicon wafers, doped germanium wafers, gallium arsenide wafers, silicon carbide wafers, indium phosphide wafers, doped polysilicon ingots, epitaxial wafers

Real World Examples

Shin-Etsu Chemical silicon wafers, SUMCO silicon wafers, GlobalWafers, Siltronic, SK Siltron

Common Misclassification

Often confused with undoped silicon (2804) or other raw chemical elements (Chapter 28) if the doping process and specific electronic application in disc/wafer form are not highlighted. The 'doped for electronics' aspect is key.

Products Classified Under 3818.00

Industry

This code belongs to the Chemicals industry.

Trade Overview

Taiwan, South Korea, Japan, and the USA are dominant in both importing and exporting due to their advanced semiconductor industries.
