How to read SIC 16230
SIC 16230 reads as division 16 (manufacture of wood and of products of wood and cork, except furniture; manufacture of articles of straw and plaiting materials), group 162, class 1623, then the full five digits, inside section C, manufacturing. A company picks its own codes, up to four, and Companies House does not check them, so 16230 is the company's own description of what it does, and 7,908 list it first where 8,021 list it anywhere.
Who sells into division 16
Joinery manufacturers sell almost entirely into construction. So the people selling to them mirror the building supply chain: timber merchants, machinery dealers, CNC tooling suppliers and trade credit insurers.

Should a joinery business choose 16230 or 43320?
Use 16230 if you make joinery in a workshop: staircases, doors, trusses and the like. That holds whether or not you fit them yourself. Use 43320, joinery installation, if your work is fitting products made by others on site. Firms that truly do both can list both codes. The split mainly affects how buyers and insurers read your company. Companies House never queries it.
