Do US export controls apply to used GPUs and processors?
Reviewed 2026-09 · reviewed quarterly
Yes. Classification follows performance parameters — not the age, price or provenance of the item. Advanced computing items under ECCN 3A090 and 4A090 — A100, H100, H200 and B-series class accelerators, plus certain high-end processors — remain controlled when sold second-hand. The control most often missed is not the destination country. It is the ultimate parent headquarters rule: a licence is required where the buyer, or the buyer’s ultimate parent, is headquartered in Country Group D:5 or Macau — wherever that buyer itself is located. ZHPAY’s position is simple: we trade only items that are not export-controlled and not on any prohibited list. Controlled accelerators are not handled.
Does second-hand status change anything?
No. Export control looks at the performance parameters and technical specification of the item, not whether it is new or used, what it costs, or where it came from. An accelerator pulled from a decommissioned server classifies exactly the same as a boxed new one of the same model.
What is the rule that catches most sellers?
Not the destination country — the location of the buyer’s ultimate parent headquarters. Many sellers check which country the shipping address is in and assume that settles it. If the buyer’s parent company is headquartered in a restricted country or territory, a licence is still required, wherever the buyer itself sits.
How does ZHPAY handle this?
We avoid it at the source: we trade only items that are not export-controlled and not on any prohibited or controlled list. Controlled high-end AI accelerators are neither bought nor sold by us. That keeps it simple for both sides, and it does not push the compliance burden onto the customer.
The four layers of screening
Most sellers check one or two of these and assume they are covered. The layers that catch people out are the third and fourth.
| Layer | What you check | Why it is not enough on its own | |
|---|---|---|---|
| 1 | Denied party lists | Buyer name against BIS Entity List, SDN, Unverified List | A clean name check says nothing about where the company ultimately reports. |
| 2 | Destination country | Where the goods are physically shipping to | A buyer in a permitted country can still be caught by the rule below. |
| 3 | Ultimate parent headquartersMost missed | Where the buyer's ultimate parent company is headquartered | This is the one most sellers miss. If the ultimate parent is headquartered in Country Group D:5 or Macau, a licence is required regardless of where the buyer itself sits. |
| 4 | End use and end user | What the parts will be used for, and by whom | Certain end uses require a licence even when every other layer is clean. |
ZHPAY avoids this problem at source: we deal only in items that are not export-controlled, so these layers rarely become a question at all. Where a transaction does need screening, we run it before quoting — not after.
