In H2 2026, a structural variable is reshaping the storage chip recycling market: domestic Chinese brands (Longsys, Biwin) are ramping up TLC/QLC production at scale, directly pressuring the recycling price of second-hand OEM TLC chips. For recyclers, this is not a simple "oversupply → price drop" — it is a value re-ranking. TLC faces downward pressure, while the scarcity premium on MLC/SLC widens, and the -40℃ to +85℃ industrial-grade eMMC certification becomes the hardest moat.
Historically, NAND Flash and eMMC chip recycling prices were driven primarily by the OEM production cycle (6-12 month swing): when Samsung, Kioxia, or SK Hynix cut output, recycling prices followed up 10%-20%; when downstream demand softened, prices could halve. Now, domestic substitution adds a supply-side variable: Longsys and Biwin TLC/QLC products are flooding phone, tablet, and industrial channels, compressing the "replacement cost" of second-hand OEM TLC chips and pushing recycling prices down.
MLC and SLC tell a different story. Domestic players' main production lines are concentrated on TLC/QLC; MLC (especially eMMC 5.1) and SLC capacity remains limited. This means Samsung and Kioxia (formerly Toshiba) MLC chips remain scarce in the secondary market, and the 30%-50% MLC-over-TLC premium is not narrowing — it is likely widening.
| Category | Capacity / Grade | Reference Price (CNY/piece) | Domestic Substitution Impact |
|---|---|---|---|
| eMMC chip | 64GB TLC | 8-15 | Downward pressure (domestic TLC/QLC ramp) |
| eMMC chip | 128GB MLC | 20-35 | Relatively resilient (limited domestic MLC capacity) |
| eMMC pulled A-grade | 64GB Consumer | 35-50 | Floor held by phone repair demand (Apple/Huawei legacy models) |
| eMMC Industrial | 64GB (-40℃ to +85℃) | 60-80 | Moat (domestic industrial-grade not yet at scale) |
| Bad block rate >5% | Any capacity | Original × 0.6-0.8 | — |

Industrial and automotive applications demand far more than "read/write capability": stable operation across -40℃ to +85℃, high endurance (MLC ≥100K P/E cycles), ECC, and bad-block management. Domestic players are still working through AEC-Q100 automotive certification and industrial-grade mass production, making it difficult to directly substitute second-hand OEM industrial eMMC in the near term. Industrial stock with OEM test reports (e.g., Samsung eMMC 5.1 Industrial) can command an additional 20%+ premium over consumer-grade pricing.
In practice, always verify the temperature marking on the chip surface during sorting. Industrial-grade chips are typically marked "-40 to +85" or "IND"; consumer-grade is marked "0 to +70." The price gap between the two can reach 50%-100%.
At equal capacity and cell type, the brand premium ranking for eMMC/NAND chips is roughly:
Use a magnifier to inspect the silk screen: clear laser engraving with a complete model number (e.g., K9FAG08U0D) and 8-digit date code = Original (正片), highest price; faded or re-etched silk screen = White chip (白片), wafer test not fully passed, mid-range price; no silk screen or severely worn = Black chip (黑片), priced as scrap. In mixed lots, inspect every piece individually — never apply a blanket price.
