Ceramic wares; for laboratory, chemical or other technical uses, of porcelain or china

HS code 690911 covers a specialized segment of the ceramic industry, focusing on the production of porcelain or china-based wares for laboratory, chemical, and other technical applications. These highly durable and heat-resistant ceramic products play a crucial role in various scientific, industrial, and technological processes, contributing to advancements across multiple sectors of the economy.

The production of ceramic wares under HS code 690911 typically involves a multi-step process. It begins with the careful selection and blending of raw materials, such as kaolin, feldspar, and quartz, to achieve the desired composition and properties. The mixture is then shaped using techniques like slip casting, jiggering, or pressing, and subsequently fired at high temperatures to achieve the final hardened and vitrified state. Quality control measures, including dimensional inspection and testing for chemical resistance, are essential throughout the manufacturing process to ensure the products meet the stringent requirements of their intended applications.

The primary inputs for the production of ceramic wares under HS code 690911 include high-purity raw materials like kaolin, feldspar, and quartz, as well as specialized machinery for shaping, firing, and finishing the products. Additionally, energy sources, such as natural gas or electricity, are required to power the high-temperature kilns used in the firing process. Skilled labor, with expertise in ceramic engineering and production techniques, is also a crucial input for this industry.

The ceramic wares produced under HS code 690911 are primarily used in laboratory, chemical, and other technical applications where their unique properties, such as heat resistance, chemical inertness, and dimensional stability, are highly valued. These products may be consumed by industries like 382100 Scientific research and development services, 325000 Chemical manufacturing, and 334400 Semiconductor and other electronic component manufacturing, among others. The outputs of this industry can also be further processed or incorporated into more complex products and systems.
