# HS code 8460.12: Flat-surface grinding machines, numerically controlled > HS code 8460.12 covers flat-surface grinding machines, numerically controlled. It sits in heading 84.60 (machine-tools for deburring, sharpening, grinding, honing, lapping, polishing or otherwise finishing metal or cermets by means of grinding stones, abrasives or polishing products, other than gear cutting, gear grinding or gear finishing machines of heading 84.61) in chapter 84 (nuclear reactors, boilers, machinery and mechanical appliances; parts thereof). Other goods of heading 84.60 are classified under 8460.19 (flat-surface grinding machines, other), 8460.22 (other grinding machines, centreless grinding machines, numerically controlled), 8460.23 (other grinding machines, other cylindrical grinding machines, numerically controlled), 8460.24 (other grinding machines, other, numerically controlled) or 5 others.

The legal text of the subheading is “Flat-surface grinding machines: Numerically controlled”, read under “Flat-surface grinding machines”, in HS2022. ## What it doesn’t cover Other goods of heading 84.60 are classified under 8460.19 (flat-surface grinding machines, other), 8460.22 (other grinding machines, centreless grinding machines, numerically controlled), 8460.23 (other grinding machines, other cylindrical grinding machines, numerically controlled), 8460.24 (other grinding machines, other, numerically controlled) or 5 others. - [8460.19](https://staging.border.bot/hs-codes/846019) Flat-surface grinding machines: Other - [8460.22](https://staging.border.bot/hs-codes/846022) Other grinding machines: Centreless grinding machines, numerically controlled - [8460.23](https://staging.border.bot/hs-codes/846023) Other grinding machines: Other cylindrical grinding machines, numerically controlled - [8460.24](https://staging.border.bot/hs-codes/846024) Other grinding machines: Other, numerically controlled - [8460.29](https://staging.border.bot/hs-codes/846029) Other grinding machines: Other - [8460.31](https://staging.border.bot/hs-codes/846031) Sharpening (tool or cutter grinding) machines: Numerically controlled - [8460.39](https://staging.border.bot/hs-codes/846039) Sharpening (tool or cutter grinding) machines: Other - [8460.40](https://staging.border.bot/hs-codes/846040) Honing or lapping machines - [8460.90](https://staging.border.bot/hs-codes/846090) Other ## How it is structured 8460.12 is a six-digit subheading. Its first two digits, 84, are the chapter; the first four, 8460, are heading 84.60; the last two, 12, identify the subheading within the heading. Countries add their own digits after these six for their national tariff lines. - Chapter 84: Nuclear reactors, boilers, machinery and mechanical appliances; parts thereof - Heading 84.60: Machine-tools for deburring, sharpening, grinding, honing, lapping, polishing or otherwise finishing metal or cermets by means of grinding stones, abrasives or polishing products, other than gear cutting, gear grinding or gear finishing machines of heading 84.61 - Within the heading: Flat-surface grinding machines - Subheading 8460.12: Numerically controlled ## In other countries No national tariff lines under 8460.12 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 8460.12 at six digits and add their own digits after it. - Previous subheading: [8459.70](https://staging.border.bot/hs-codes/845970) Other threading or tapping machines - Next subheading: [8460.19](https://staging.border.bot/hs-codes/846019) Flat-surface grinding machines: Other ## Frequently asked questions ### What does HS code 8460.12 cover?
