Direct answer

Catch-all can require a licence — or a stop — for items that are not on the dual-use list.

The Export Control Law and implementing rules require exporters to apply for a licence or halt the export when they know or should know that an otherwise uncontrolled item will be used in a prohibited programme, or when the authorities notify them of a risk. Red flags include military end users, WMD-related procurement, evasive routing, and specs that only make sense for a controlled purpose. Catch-all is fact-specific and notice-driven; there is no wiki safe harbour. Foreign catch-all (US, EU) can stack. Keep a dated ‘should have known’ file, not only a list-screening tick.

4 questions before you choose the route.

This page identifies the right question and evidence. It does not determine the legal outcome on a reader’s facts.

01

Did list screening come back ‘not listed’?

Then start catch-all; do not close the file.

Gate
02

What do you actually know about user and use?

Documents, site, ownership, open source.

Knowledge
03

Has an authority notified you?

A letter beats a gut feel and creates a hard duty.

Notice
04

Would a reasonable exporter ask more questions?

The ‘should know’ test.

Red flags

Working rule: Map the regulated role before marketing or launch in China.

What changes the answer

The signal ledger.

These facts move the question beyond a label and into a product, money-flow and control analysis.

Odd intermediaries, last-minute destination changes?

You may ‘should know’ even without a list hit.

Wilful blindness is still knowledge in practice.
Prepare before you escalate

Bring a compact evidence docket—not a pitch deck.

Give a compliance team or counsel the operating facts that reveal the perimeter.

01List-negative memoWhy the item is not listed, dated.
02KYC on user/useWhat was asked, what was answered, what was refused.
03Open-source packSite, tenders, ownership.
04NoticesAny government contact on this deal.
Common confusions

Questions people ask before they build.

Short answers for orientation. The right result can change with the service model and current rules.

If we did not know, are we safe?

The test includes should-know and official notice. A thin KYC file is how ‘we did not know’ fails.

Does catch-all mean every civil export needs a licence?

No. It means unlisted plus red-flag user/use needs a decision, sometimes a licence application, sometimes a no-export.
