eBay used graphics-card market (GeForce RTX 4090 as reference used accelerator)

USED / Pre-Owned, bare PCIe graphics card, no server, as-is, no warranty stated. $2,000.00 is the ASUS TUF Gaming RTX 4090 24GB listing = LOW end of genuine used 4090s in the captured result set; genuine used 4090s ran $2,000-$3,000 with the bulk at $2,500-$3,000 (MSI GAMING X TRIO $2,999.00, ASUS ROG Strix OC $3,000.00, Zotac Trinity OC $2,999.00). Captured 2026-10-03 from eBay.com used-only search _sacat=27386, 60/page. These are ASKING prices on live listings, not completed sales PERISHABLE-FIGURE STAMP (added 2026-10-04, uniform across data/supply/ so it is greppable). PRICE CLASS: ASKING price - the rate at which a seller advertises the item for sale, NOT a sold, completed or realised transaction price. OBSERVED: 2026-10-03 RE-VERIFY BY: 2027-01-04 - the repo's quarterly re-verification bar. After that date this figure is presumed drifted and must be re-checked against its source before it is quoted again. A price without its observation date is noise; this stamp exists so a reader can tell a fresh figure from a stale one without reading prose. UNIT: USED / Pre-Owned, bare PCIe graphics card, no server, as-is, no warranty stated READING RULE: No further perishable flag is published for this figure.

lead_time_weeks is null because no lead time applies: this is a secondary/auction market priced per listing. What a buyer faces is listing availability at the moment of purchase - the record's availability field is a snapshot of what a seller posted, not a schedulable delivery date - plus whatever shipping the listing states. An auction close date is not a lead time.

EAR 3A001 or EAR99 (below the 3A090.a TPP / performance-density thresholds) + EAR 744.23 (Entity List) + EAR 744.6 (Unverified / MEU lists)

MECHANISM: the part falls BELOW the ECCN 3A090.a/.b TPP and performance-density thresholds, so the advanced-computing licence regime, its case-by-case China/Macau carve-out and its D:5 screening do NOT attach. What remains is the general EAR plus destination-country import rules and screening of the consignee and its ultimate parent against the Entity, Unverified and MEU lists. NO LICENCE REQUIRED for the sale itself; the screening is a party-listing check, not a performance-threshold check. The binding ECCN determination for any specific part is the exporter's own classification, not this record.

Most liquid, best-documented used accelerator channel in this slice: ~50 genuine used consumer cards on one used-filtered page, brand facets ASUS 292 / MSI 254 / NVIDIA 250 / EVGA 192 / GIGABYTE 192 / ZOTAC 122 / PNY 42. Price buckets: under $1,400 / $1,400-$2,800 / over $2,800. RISK - TITLE-POLLUTION TRAP observed directly in the data: the cheapest '4090' listings are not 4090s. They are (a) cooling hardware with NO GPU - MSI SUPRIM LIQUID X heatsink+watercooler+PCB at $239.99, ASUS ROG Strix LC enclosure+cooler only at $399.95, ASUS LC water cooler $289.99, Manli RTX4090 PCIe adapter $319-$435; and (b) WRONG-VRAM SKUs - 'ASUS ROG XG Mobile eGPU Dock RTX 4090 16GB GDDR6' at $1,499.99 and $1,999.99, which is a 16GB laptop die, not the 24GB desktop part. Any tool taking 'cheapest used 4090' without parsing titles returns a heatsink. Other risk: used consumer cards carry no transferable NVIDIA warranty, no NVLink, no ECC, and are consumer dies - not a substitute for A100/H100 in a memory-capacity-bound serving role. Spare-parts prices observed in the same set (what a refurb house cannibalises, not what you deploy): A100 40G/80G heatsink only $199.00, H100 SXM5 4-GPU NVLink backplane $1,800.00, V100 SXM2 16GB module $65.00, V100 32GB SXM3 tested $425.00. EXPORT CONTROL (2026-10-04, mechanism-level; source spl-eccn-3a090-ccl): consumer gaming cards of this generation generally do NOT meet the 3A090.a TPP/performance-density parameters and fall under ECCN 3A001 or are designated EAR99, i.e. the advanced-computing licence regime with its case-by-case and D:5 screening does not attach to them. This is exactly what makes export status a PER-PART property rather than a per-vendor one: a GeForce RTX 5090 and a datacenter/professional part from the same vendor and the same process generation can carry entirely different control status. Recorded as false for that reason, NOT because the part is unregulated - it remains subject to the EAR generally, to destination-country import rules, and to screening of the consignee and its ultimate parent against the Entity, Unverified and MEU lists (15 CFR part 744). The binding ECCN determination for any specific SKU is the exporter's own classification, which no public vendor page states. LEAD TIME: null, and deliberately so. A marketplace or big-box reseller publishes STOCK STATE, not a lead time - where this record shows in-stock that means the listing was available on the observation date, and where it shows backorder no week window is published at all. Converting one into the other would be an invention. The one exception in the whole chain is CDW, which does print windows (source spl-cdw-published-lead-times-gpu-2026-10); note that even there the scarcest SKUs - the RTX PRO 6000 96GB cards and DGX Spark - read 'Item Backordered' with NO estimate, so scarcity and lead time are inversely related in what distributors actually publish.
