HS classification for custom hardware and fasteners:

What goes wrong with custom hardware and fasteners
- Specifying a finish by appearance instead of by standard, then getting a coating that fails in salt spray.
- Accepting a lower stainless grade without noticing.
- Not specifying thread tolerance and discovering the parts do not mate.
- Assuming standard parts are always available; Chinese "standard" dimensions sometimes follow GB rather than DIN or ANSI.
- Ignoring anti-dumping exposure on fasteners.
