SIC Code 2231 — Broadwoven Fabric Mills, Wool (Including Dyeing and Finishing)

4-digit industry in the 1987 Standard Industrial Classification — still requested by banks, insurers, SEC filings and legacy systems.

Code	2231
Title	Broadwoven Fabric Mills, Wool (Including Dyeing and Finishing)
System	SIC 1987 (final edition — replaced by NAICS in 1997)

The SIC was last revised in 1987 and officially superseded by NAICS in 1997, but it never fully disappeared: the SEC still tags EDGAR filings with SIC codes, and many banks, insurers and legacy databases keep requesting it. That is why converting between the two systems is still routine work.
