Manufacture Of Flat Glass

Details for Manufacture Of Flat Glass

SIC code 23110 is used for businesses carrying out activity in the field of manufacture of flat glass. In plain English, it is likely to include manufacturers, workshops, processors, fabricators, producers and industrial suppliers, with day-to-day activity often involving materials, production runs, quality control, machinery, components, packaging and supply-chain delivery. As of June 2026, 23110 ranks 626th out of 731 five-digit SIC codes, with 219 UK companies registered under it, making it a specialist or niche sector on the UK register.

This sits within a classification system that has been used in the UK since the 1940s; Companies House filings moved from 4-digit SIC 2003 codes to the current 5-digit SIC 2007 scheme in 2008–2009, bringing the UK register into line with NACE Rev. 2. The four-code limit at Companies House is useful here, as many businesses use one code for their main trade and additional SIC codes for secondary services, side operations or closely related commercial functions.

The short official label is deliberately compact, so the real-world businesses behind it may describe themselves using broader phrases such as manufacture of flat glass services, specialist manufacture of flat glass providers, operators in related supply chains, or companies supporting customers who need this form of commercial activity. A company using this code might be newly incorporated, dormant, small and owner-managed, or part of a larger group, so the SIC entry should normally be read alongside accounts, confirmation statements, websites and other commercial signals. The classification is especially valuable when comparing suppliers, prospecting for customers, segmenting a database, reviewing competition or checking how a company presents its principal line of business on the public record.

For search and data work, the wording should be understood broadly: companies may use different everyday terms for the same activity, including trade names, sector jargon, abbreviated service descriptions and customer-facing language. The code therefore works best as a structured indicator of economic activity rather than a complete profile of the company, because many organisations evolve, add services or reorganise after incorporation.
