Treatment and coating of metals; machining
What this code covers
Use this group for treatment and coating of metals; machining when the main activity includes Coating of metals and Heat treatment of metals. Check exclusions and nearby codes before applying it to a mixed activity.
Official NACE Rev. 2.1 labels and explanatory notes are imported from the source dataset. Plain-language explanations are shown separately so readers can compare interpretation with the source text.
- This group includes general activities for the treatment of metal (for example, plating, coating, engraving, boring, polishing or welding), which are typically carried out on a fee or contract basis.
- Activities primarily classified as manufacture of structural metal products
- Activities primarily classified as manufacture of tanks, reservoirs and containers of metal
- Activities primarily classified as manufacture of weapons and ammunition
- Activities primarily classified as forging and shaping metal and powder metallurgy
- Compare with 25.1, 25.2, 25.3 when the main activity overlaps another code.
- Review the Rev. 2 to Rev. 2.1 mapping type before migrating old records.
- Check national equivalent caveats before using this code for local registration or filing workflows.

What is NACE 25.5 used for?
Use NACE 25.5 for treatment and coating of metals; machining when the main activity matches this scope: Use this group for treatment and coating of metals; machining when the main activity includes Coating of metals and Heat treatment of metals. Check exclusions and nearby codes before applying it to a mixed activity.
What are typical examples for 25.5?
Typical examples include Coating of metals, Heat treatment of metals, and Machining of metals.
When might 25.5 not be the right code?
No separate exclusion examples are available for this record yet; compare nearby hierarchy records before final selection.
Which codes should I compare before choosing 25.5?
Compare 25.5 with 25.1 Manufacture of structural metal products, 25.2 Manufacture of tanks, reservoirs and containers of metal, and 25.3 Manufacture of weapons and ammunition when the activity description is ambiguous.
Use this group for manufacture of structural metal products when the main activity includes Manufacture of metal structures and parts of structures and Manufacture of doors and windows of metal. Check exclusions and nearby codes before applying it to a mixed activity.
Use this group for manufacture of tanks, reservoirs and containers of metal when the main activity includes Manufacture of central heating radiators, steam generators and boilers and Manufacture of other tanks, reservoirs and containers of metal. Check exclusions and nearby codes before applying it to a mixed activity.
Use this group for the broader activity area of manufacture of weapons and ammunition, including Manufacture of weapons and ammunition. Open the child codes when a more specific code is needed.
Use this group for the broader activity area of forging and shaping metal and powder metallurgy, including Forging and shaping metal and powder metallurgy. Open the child codes when a more specific code is needed.
Use this class for coating of metals when the main activity includes Galvanising, including general (batch) hot-dip galvanising and Phosphate or chromate conversion coating. Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for heat treatment of metals when the main activity includes General activities for the heat treatment of metals and Thermomechanical heat treatment of metals (e.g. preheating, annealing, hardening, tempering, quenching, deep freezing of metal). Check exclusions and nearby codes before applying it to a mixed activity.
Use this class for machining of metals when the main activity includes Boring, turning, milling, eroding, planing, lapping, broaching, levelling, sawing, grinding, sharpening, deburring, sandblasting, tumbling, polishing, buffing, welding, splicing, etc., of metalwork pieces and Cutting of and engraving or writing on metals by means of laser beams. Check exclusions and nearby codes before applying it to a mixed activity.
Use this division for manufacture of fabricated metal products, except machinery and equipment when the main activity includes The manufacture of weapons and ammunition is also included in this division.. Check exclusions and nearby codes before applying it to a mixed activity.
Rev. 2 code 25.6 maps to 25.5 Treatment and coating of metals; machining, but the relationship is scope-aligned rather than a simple unchanged code.
Official close match imported from NACE Rev. 2.1.
Datasets, CRM segments, KYC rules, reporting logic, and historical joins may need review because the activity scope is not a simple unchanged carry-over.
Review the official explanatory notes for each target code and confirm whether the business activity still fits the suggested Rev. 2.1 class.
