Are You Selling “A-Grade”—or Dumping Leftovers? A Buyer’s Checklist Before You Wire.
☑️ If you’ve been burned by “A-Grade” before, you already know the pattern:
The invoice says A-Grade, but the carton says mixed grading, hidden defects, and margin killers.
☑️ Here’s the reality: most “A-Grade disasters” aren’t caused by one bad unit.
They’re caused by a supplier who doesn’t run a quality system.
☑️ This post is the checklist serious buyers use—written in the same blunt questions you’d ask on WhatsApp— plus how RingSycle answers them with proof.
“Are you selling A-Grade—or dumping leftovers?”
If a supplier can’t define A-Grade in writing, “A-Grade” is just a sticker.
Before you wire, demand a written A-Grade standard:
Cosmetic rules (no cracks, no bent frames, allowed wear level)
Parts policy (what counts as “original” and what doesn’t)
Functional baseline (Face ID, cameras, speakers, buttons, sensors)
Battery threshold (minimum %)
RingSycle’s rule:
We don’t sell “A-Grade vibes.” We ship A-Grade criteria—repeatable and documented.
“Will my ‘A-Grade’ arrive as A/B mix?”
This is the fastest way to destroy your margin in bulk.
Ask this directly:
Do you ever mix grades to move inventory?
If mixed grading is found, what’s the resolution policy?
RingSycle’s rule:
No Mixed Grading. A-Grade means A-Grade—no “A/B”, no “mostly A”, no “close enough.”
“Show me proof: battery, functions, IMEI—before I wire.”
If the supplier can’t show proof, you’re paying for hope.
Battery proof (not “good battery”)
Battery health is measurable. Apple states iPhone batteries are designed to retain 80% of original capacity at 500 charge cycles for iPhone 14 and earlier, and 1000 charge cycles for iPhone 15 models (under ideal conditions). Apple Support
That’s why buyers set a hard threshold (e.g., 80%+) and ask how it’s verified.
RingSycle’s rule:
We use a defined battery threshold and unit-level checks—so “80%+” isn’t a claim; it’s a gate.
Function proof (not “tested”)
“Tested” must mean a checklist—not a guess.
Minimum checks buyers should demand:
Face ID
Cameras (front/back)
Speakers/mic
Buttons/sensors
Display & touch
RingSycle’s rule:
Every unit is tested, checked, and graded by our in-house workflow—consistency comes from process.
IMEI proof (traceability, not chaos)
IMEI is a 15-digit unique identifier for devices on mobile networks (GSMA). GSMA
If you don’t get an IMEI list, you lose traceability the moment the lot lands.
RingSycle’s rule:
We provide IMEI-based traceability so issues can be isolated quickly—no finger-pointing, no “good luck sorting it.”
“Are you a one-time seller—or a supply partner?”
One good shipment doesn’t prove reliability.
Consistency does.
Before you commit, ask:
Do you have weekly stock flow?
Can you support mid-size and large buyers (MOQ flexibility)?
How often do you update inventory?
RingSycle’s rule:
Weekly stock flow and repeatable operations—built for long-term wholesale relationships, not one-off deals.
“Can you ship clean—or will logistics become my problem?”
Export pain kills deals even when the devices are fine.
Buyers should confirm:
Secure packing standards
Export-ready documents (invoice, packing list, required paperwork)
Tracking + dispatch discipline
RingSycle’s rule:
Export-ready packing, documentation, and support are part of the standard delivery—not an add-on.
