Export Controls/ EAR & Re-Export Routing : Why IOR/EOR should be designed first for initial AI data-center inbound ②

AI accelerators, servers, networks, and batteries often fall under U.S. EAR and local export controls. The practical sequence is ECCN classification → End-Use/End-User (EUU) declaration → re-export routing check → licensing timeline → IOR/EOR execution. Skipping this groundwork raises risks of customs delays, returns, penalties, and insurance non-recognition.

“Logistics that speaks with data” — Insight from Korea’s strategic logistics frontline

1) ECCN vs. HS: different purposes

What: determine ECCN by function, performance, crypto, firmware.
Why: HS is for tariff/statistics; ECCN drives licensing decisions.
Watch-outs: GPUs/accelerators, high-end servers/storage, switches/optics, test gear, BMS.

ECCN pre-screen checklist available.

2) EUU: make use & user transparent

End-Use: actual purpose (training/inference, medical, research).
End-User: end-user entity + operating partner (if any).
Must-have clauses: non-military/non-proliferation, no third-country transfer, post-monitoring consent.

EUU template (2 pages) on request.

3) Re-export routing: transit can change the rulebook

EAR reach: U.S. origin/tech may attach to transit/re-export.
Checks
1. sanctions/lists for origin-transit-destination
2. mixing of controlled items in CFS/FTZ/bonded zones
3. nationality/access rights of install/remote teams (tech-transfer)

Five common routing scenarios available as cards.

4) Licensing timeline: not just “apply,” but “schedule”

Suggested cadence
- Wk 0–1: scope, manufacturer classification/CCATS
- Wk 2–3: internal ECCN pre-class + EUU collection
- Wk 4–6: filing & RFI prep
- Wk 6–10+: review/conditional approval/supplements
Contract tip: PO contingent on license to share lead-time/cost risk.

Sample Gantt (Excel/Cal) available.

5) IOR/EOR: the legal actors that make execution real

IOR (Importer of Record): local legal responsibility for customs/tax/compliance.
EOR (Exporter of Record): reverse flows (RMA/replacement/re-export).
Effect: schedules anchor to process, not individual discretion.

Country-by-country IOR/EOR comparison available.

6) Common failure patterns & fixes

“Sail first, paperwork later” → license/EUU first.
Provisional ECCN → audit/insurance risk; get manufacturer attestation.
No access-rights model → remote/FW updates may count as tech transfer.
No re-export plan → document EOR flow for move/withdrawal.

Close & next steps

AI inbound is a single critical path: ECCN – EUU – routing – license – IOR/EOR – installation.Provide item, quantity, site, target date to receive a 10-point risk screen and a one-page license/routing calendar.
