Japan's control list moved twice this year: how long is a supplier's not controlled statement good for?

Aya Morimoto jpExport Control Officer · An industrial machinery maker, Osaka

Forgive me if this is obvious to everyone except me. It is my first day here, and my English is careful rather than quick.

Our control list here moved twice this year. One revision took effect on 14 February. Another took effect on 16 August, and that one also widened the advance notice expected before technology is provided to a party overseas. A compliance column I read this week made a point I cannot put down. A classification determination is only as good as the version of the list it was made against, and the version, with the date, is what nobody writes down.

That is what the text says, as I read it. What my desk does in practice is narrower. We re-run our own determinations when a revision touches the items we sell, and we write a statement for any customer who asks for one. What we do not do is go back to a customer we told two years ago that a machine was not listed.

So the question is really for the buying side, because you are the ones holding our paper. When a supplier tells you goods are not controlled, do you record which version of the list that was written against, and do you ever ask again? Or does it go into the file once and sit there until an audit opens the drawer?

One honest limit. The ministry's own notice pages would not load for me today, so I am reading summaries and not the text. I may have this wrong.

Under EU dual-use rules a determination has no stated shelf life. Licences expire, classifications do not. We may rely on a supplier's classification while it stays plausible, and one written against a withdrawn list fails that test quietly. So the stamp needs two dates, not one: the list version judged against, and the day judged. Our list moved this month. I read a practitioner guide, not your ministry's notice.

Thank you, that is the piece I was missing.

Your two dates are already on our form here, which surprised me. A determination sheet in my market customarily names the regulations it was judged under, as a version effective from a stated date, and separately the day it was judged. So your test can be run on our paper, when both fields are really filled in.

What is missing is the push. There is no stated validity, and a supplier here is not obliged to tell you when a later revision changes an old determination. The paper is honest about what it was and silent about what it became.

So ask us again before you ship, and keep the answer. Nobody will volunteer it.

The ministry's pages still will not open for me, so this is practitioner guidance, not the notice.

Aya, I am on the buying side, and ask again before you ship is a sentence that hides a routine. Here is ours, caveats included.

We stopped waiting for the supplier to come back and bought the push instead. Our declaration form carries an undertaking: re-confirm on a stated cycle, and tell us in writing as soon as they know of a change, including a change in the rules rather than in the part. It only binds the ones who sign it.

The trigger is the revision, not a calendar. When a list moves, somebody has to read what moved and pull the lines sitting near it. That reading is the step a busy week eats, and it is the whole control.

The chase belongs to whoever holds the purchase order. Compliance has no leverage with a supplier; a buyer does. We give them a working week.

Then the honest part. Silence does not stop a shipment. Temperature controlled stock does not wait, so we write our own determination, log that the supplier never answered, and ship on our name rather than theirs. That moves the exposure onto me, on the day, by choice.

Am I overbuilding something that is really just file discipline?
