Division 30: Manufacture of other transport equipment
Everything that moves except cars and lorries. Air and spacecraft, 30300, is the largest code, followed by the catch-all 30990 and pleasure boat building at 30120. Shipbuilding and rolling stock sit below the threshold in company terms, which is what you would expect of industries with a handful of very large employers rather than many small ones.

Who prospects SIC 30990 companies
Aerospace is the part of this division with the most active supplier market: precision machining, composites, certification and quality consultancy, and specialist recruitment. Boat building is a different world with its own buyers of marine hardware, resins and rigging. The two rarely overlap, so treat 30300 and 30120 as separate markets rather than one division. Aerospace clusters visibly around Bristol and the south west, and boat building around the south coast.

SIC 30990 is a five-digit code, and the digits are not arbitrary. The first two, 30, are the division, manufacture of other transport equipment. Add the third and you have group 309; the fourth narrows it to a class, and the fifth to the subclass, which is the level Companies House actually asks a company to pick. The whole division sits under section C, manufacturing, the broadest tier there is. Reading a code left to right therefore goes from a whole sector down to one activity.
More on how SIC 30990 is built
A company chooses its own codes when it incorporates and can change them on any confirmation statement. It may list up to four, and Companies House does not check whether they are right. That is why 30990 is worth reading as a claim the company made about itself rather than as a verified fact, and why the first-position and any-position counts above differ.
Measured on the August 2026 register, the busiest registered-office post towns for 30990 are London (57), Birmingham (19), Coventry (14), Leeds (10) and Manchester (10). Those are registered-office locations, which is where the paperwork sits rather than necessarily where the work happens, so treat them as where to start looking rather than as a service area.
Using SIC 30990 as a filter
885 companies is 0.02 per cent of the 5,190,464 active companies on the UK register, and ranks 30990 second most used of the 3 codes we track in division 30. That is the pool before any filter. Whether it is a big market for you depends on what you sell, but it is the number every other filter on this page cuts down from.
More on filtering by SIC 30990
Almost everybody who uses 30990 means it: 757 of 885 companies put it first, leaving only 128 carrying it as a secondary code. That makes it an unusually clean filter. You can match on the code alone and trust that the companies you get really are in this line of work.
These companies are spread out. London is the largest single cluster at 6 per cent and the top five post towns together hold only 12 per cent, so the remaining 88 per cent sits across the rest of the country. A regional filter narrows this list without gutting it, which makes it a reasonable code to work territory by territory.
In practice the code on its own is rarely the whole filter. Pair 30990 with an incorporation date to catch companies in their first months, when they are still choosing suppliers, or with a filing deadline to reach them while the year end is on their mind. A worked example for this code: 30990, registered office in London, incorporated in the last ninety days, which turns a 885 company pool into a list you can write to in an afternoon. Add the poor-website filter if what you sell is a website, or a recent change of officer if you sell to whoever just took the job. Every company you pull carries the Companies House record, the director's name, a verified website and a verified email, and the ones we cannot complete are not charged.

About SIC 30990

885 active UK companies list 30990 (Manufacture of other transport equipment n.e.c.) among their registered SIC codes. Each company may register up to four. Of those, 757 put it first. The figures come from the August 2026 Companies House register snapshot, and count active companies only.
Are aerospace maintenance companies in 30300?
Not usually. 30300 is manufacture of air and spacecraft. Maintenance, repair and overhaul normally sits in 33160, repair and maintenance of aircraft and spacecraft, in division 33. Suppliers who serve both should pull the two codes together, since the customer base overlaps heavily.
Where do caravan and motorhome builders sit?
In 30200 or 30990 depending on the build, though caravan manufacture specifically has its own code at 29200 for bodies and trailers. It is one of the messier corners of the classification and companies split across several codes, so match on any position and expect to tidy the list by hand.
