HS/Tariff Code for Breakout Boards

Greetings All!

i am curious what other sellers are using for HS/Tariff code for small breakout boards. i’ve been digging around and it seems there is a very wide range of usage for this. digikey and element14 seem to all use a generic code for computer components, however i have seen a number of places using more specific ones, most notably the HS Code 8542.31 , anyone have some feedback or insight they could share?


I use 854370

Which seems to be

Electrical machines and apparatus, having individual functions,
not specified or included elsewhere in this chapter; parts
thereof: (con.)
Other machines and apparatus:

So far so good.

854231 would be
Electronic integrated circuits; parts thereof:
Electronic integrated circuits:
Processors and controllers, whether or not combined
with memories, converters, logic circuits, amplifiers,
clock and timing circuits, or other circuits…

which might be the thing if my stuff had a processor (does an ATtiny count?) , but at this time it does not.

Disclaimer: I have no idea what I’m doing.
