Why White-Label Now

The brands are leaving commodity flash. That's your shelf space.

As NAND tightens, the majors are reallocating capacity to high-margin enterprise and AI and quietly stepping back from commodity and consumer cards. Distributors who can't get brand-name stock — and resellers whose retail-arbitrage margin has been squeezed flat — need a different source: a clean factory line they can put their own name on, with supply that holds and a BOM that doesn't change behind their back. That's what white-label from the source factory is for.

Your brand, factory-directSkip the trading desks — source-factory output marked, packed and locked under your name.
Traceable, not co-mingledBuilt and tested on the line — never marketplace stock where a genuine listing ships a fake.
Supply that holdsFactory allocation: stable lead times for your brand while spot supply dries up.

What We OEM

Your brand, on the shell and in the box

White-label and full OEM across our microSD & TF card range. Pick the level of customization; we state the grade and rated specs on the quote, not just your logo.

A
Brand silkscreen

Your name and artwork printed on the card or drive shell — clean, repeatable, batch-consistent.

B
Laser marking

Permanent laser-engraved branding, part numbers and serials — no print to wear off.

C
Preload

Ship with your files, firmware, catalog or recovery image already written — ready out of the box.

D
Partitioning

Custom partitions and CD-ROM / auto-run zones for installers, manuals or licensing.

E
Custom packaging

Retail blister, box and insert design, or bulk/bare for your own assembly line.

F
Locked part numbers

Your SKU fixed per order, so re-orders match the exact product you qualified.

G
Fixed BOM

Controller, NAND mode and firmware fixed per order — no quiet swap to cheaper NAND next batch.

H
Firmware lock

Firmware version locked and validated per order for repeatable, qualifiable behavior.

How It Works

From inquiry to shipment, one source factory

A straight line from spec to delivery — no trading desks in the middle, one factory standing behind every step.

01
Inquiry

Send product, capacity, grade, customization and monthly volume. We confirm feasibility and the real MOQ for that exact configuration.

02
Sample

A sample batch from existing tooling — your marking on stock product. Run H2testw on it yourself before you commit.

03
Prototype

Bespoke packaging, preload, partitioning or firmware built and approved — one tooling and sign-off round.

04
Mass production

Built to a fixed BOM and locked part number, so volume matches your approved prototype.

05
QC

100% H2testw capacity test with a report per batch; traceable, on an automotive-grade line — not co-mingled stock.

06
Ship

Clean Hong Kong invoicing, USD/HKD settlement, export-ready worldwide.

FAQ

OEM & white-label — sourcing questions

What can you OEM or white-label?
Across our microSD and TF card lines: brand silkscreen and laser marking, custom retail and bulk packaging, preload of files or images, partitioning and CD-ROM/auto-run zones, locked part numbers, a fixed BOM (controller, NAND mode and firmware), and firmware lock per order. You can take finished retail product or bulk/bare for your own assembly. We state the NAND grade and rated specs on the quote and datasheet — not just your logo on the shell.
What is the minimum order quantity (MOQ)?
It scales with how much customization you need. Plain or lightly marked stock starts from carton-level MOQ for resellers; full white-label runs — custom packaging, preload, locked part numbers — sit at a higher tier; bespoke firmware or industrial wide-temp builds higher again. Tell us the product, capacity and customization and we return the real MOQ for that exact configuration.
How long do samples and prototypes take?
A sample batch from existing tooling — your marking on stock product — is the fastest path, and we welcome you running H2testw on it before you commit. A full custom prototype with bespoke packaging, preload or firmware takes longer because it adds a tooling and approval round. Sampling and prototype lead times depend on the configuration and current allocation, so we quote them per project rather than promising a fixed day count.
Can you lock the BOM and part numbers?
Yes — this is the core of why buyers come to a source factory instead of the spot market. We fix the BOM (controller, NAND mode and firmware) and lock the part number per order, so the product you qualify is the product you re-order. No silent swap to cheaper NAND on the next batch, which is what quietly wrecks an RMA rate. Every batch is 100% H2testw tested with a report, traceable, and built on dedicated allocation — never co-mingled marketplace inventory.
Can you supply during the 2026 NAND shortage?
Yes. As the authorized channel of an IATF 16949 source factory we confirm price and lead time at order, so they hold firm while spot supply dries up and big brands exit commodity and consumer lines. That exit is exactly the white-label opening: distributors who can no longer get brand-name stock need a clean, traceable factory source they can put their own name on. Resellers squeezed on retail-arbitrage margin get a direct factory source that leaves room to profit — without the co-mingled, counterfeit-prone marketplace stock that is breaking buyer trust.
Do I get a traceable, counterfeit-free supply?
Every order is built and tested on the factory line, not pulled from co-mingled marketplace inventory where a genuine listing can ship a fake. Each batch is 100% H2testw capacity-tested with a report, the BOM is fixed and the part number locked, and batches are traceable. Your distributor can prove real capacity to the end buyer and re-run H2testw on arrival — a level of supply-chain purity the commodity marketplaces can no longer guarantee.
