Chinese NAND Now Supplies ~15% of the World — Yet the Recycling Market Still Treats It as "No-Name" Scrap
The global NAND Flash market has long been dominated by Samsung, SK Hynix, Micron and Kioxia — but the landscape has changed. Yangtze Memory (YMTC), ramping from 32-layer production in 2018 through three Xtacking architecture generations, is now the world's third-largest NAND maker, holding roughly 15% of global bit shipments in 2026, with Chinese-made flash passing 30% penetration inside China's eMMC/UFS/SSD supply. Yet the recycling market's perception of YMTC dies is stuck in the "no-name parts" era — many recyclers still lump YMTC dies in with white-label and black-grade silicon, sold by weight. Here is the reality: Zhitai TiPlus7100/Ti600, Gloway Yi Pro, Fanxiang S770, Hikvision, Lexar (Longsys) and Netac SSDs and portable SSDs ship in the tens of millions, and retired drives now feed tens of millions of YMTC dies into the recycling pipeline every year. Chinese 3D NAND is not a no-name part — it is genuine original-brand silicon backing ~15% of global supply, and its under-valuation is precisely the opportunity.
Why YMTC Die Recycling Is Worth Doing Right Now
The recycling value of YMTC dies rests on three structural factors:
- Explosive supply growth: tens of millions of domestic SSDs and portable SSDs ship annually; Zhitai/Gloway/Fanxiang/Hikvision drives retire fast, and notebook/desktop OEM teardown constantly yields YMTC-equipped drives
- A mature Xtacking die channel: Xtacking 3.0/3.0+ 232-layer TLC/QLC dies already have established outlets in DIY SSD assembly and USB/portable-SSD capacity-upgrade builds, and the LGA-to-BGA reballing chain is fully interchangeable with Samsung/SanDisk dies
- Clear price tiers: TLC vs QLC and 128-layer vs 232-layer spreads are well defined, so sorted lots turn over fast with stable margins
The YMTC die problem is never "no demand" — it's "selling everything mixed." Sorted by brand and generation, a batch sells 30-50% higher.
YMTC Die Recycling Price Reference
Current reference prices for mainstream Chinese 3D NAND dies (Reference Price (CNY) per die, Q3 2026):
| Die capacity | Representative dies | Reference Price (CNY) |
|---|
| 128Gb (16GB) TLC | YMTC X2-9060 (128-layer) | 4-8 |
| 256Gb (32GB) TLC | YMTC X3-6070 (232-layer) | 8-15 |
| 512Gb (64GB) TLC | YMTC X3-9070 (232-layer) | 18-35 |
| 1Tb (128GB) QLC | YMTC X3-9070 QLC (232-layer) | 25-45 |
Note: These are Q3 2026 reference ranges. Tested-good teardown drives fetch about CNY 60-120 per 1TB TLC drive (e.g. Zhitai TiPlus7100) and CNY 40-80 per 1TB QLC drive (e.g. Zhitai Ti600). Relative to same-capacity Samsung K9 original dies, YMTC TLC runs 20-30% lower and about 10-20% below SanDisk BiCS5; QLC prices at roughly 70% of same-capacity TLC. Dies with clear markings and traceable origin (stripped from branded drives) command the most.
Identification & Grading: Four Moves That Set the Price
- Verify markings and watermark: YMTC original dies carry crisp "YMTC" silk-screen logos and date codes, clearly distinct from relabeled white-label parts; dies from traceable branded drives are quoted separately at a premium
- Grade TLC vs QLC: 232-layer QLC (Ti600 teardown) dragged into TLC lots pulls the whole batch down — keep types and generations separate and quote QLC at roughly 70% of TLC
- Confirm controller pairing: YMTC dies are predominantly paired with domestic controllers such as the Maxio MAP1602 and InnoGrit IG5236; reballed dies flow straight into same-platform SSD assembly, and compatibility verification is a precondition for graded shipment
- Reball and test: after LGA-to-BGA reballing, bin by bad-block rate and grade; the pass rate sets the whole lot's price tier
Done right, a Chinese-NAND batch sells 30-50% higher; selling YMTC dies by weight as no-name scrap is giving away the third-largest NAND maker's silicon as if it were waste plastic.
Who Buys Teardown YMTC Dies?
- DIY SSD assembly and capacity-upgrade houses: domestic platforms (Maxio/InnoGrit controllers + YMTC dies) have a clear cost advantage, with steady demand for teardown dies
- USB drive / portable SSD makers: high-volume buyers taking QLC and TLC by tier, absorbing healthy dies continuously
- Storage repair market: after reballing, dies feed eMMC repair and BGA replacement — the same chain as Samsung/SanDisk dies
- Die traders and overseas buyers: some overseas markets have explicit demand for teardown Chinese NAND as an alternative where new supply is restricted — keep export compliance and brand-label declarations in order
Advice for Recyclers and Dismantlers
- Do not treat genuine domestic parts as no-name scrap: quote YMTC dies stripped from Zhitai/Gloway/Fanxiang/Hikvision drives as original-brand silicon and store them separately
- Buy and quote TLC/QLC separately: QLC runs ~70% of same-capacity TLC — mixing hands the spread away for free
- Verify markings and preserve origin: traceable dies command a clear premium, and a brand declaration accompanying shipment makes lots easier to close
- Ride the domestic-substitution curve: China's storage self-sufficiency keeps rising and domestic SSDs already exceed 30% share — YMTC supply will only grow
- Keep data security front and center: teardown drives often hold sensitive data; proactively offer erasure/destruction (NIST 800-88 methodology) — the key to corporate client trust
