How to QC (Quality Check) Replicas: Complete Guide 2026
Last updated: March 2026 By the FINDS team — QC'd thousands of items across 50+ hauls
TL;DR – Quick QC Checklist
When your QC photos arrive, check these things in order:
- Correct item? — Right color, right size, right product
- Overall shape — Does the silhouette look right compared to retail?
- Colors — Are they accurate? (Account for warehouse lighting being slightly off)
- Logos and branding — Correct placement, spelling, proportions
- Stitching — Clean, even, no loose threads
- Materials — Does the texture look right for the product?
- Tags and labels — Correct for the brand (if you care about 1:1)
- Defects — Stains, glue marks, dents, scratches
If everything passes, GL (Green Light) it. If there are major issues, RL (Red Light) and request a return. For a detailed breakdown of GL vs RL decisions, check our GL vs RL guide.
What Are QC Photos and How Do You Get Them
When you order an item through a buying agent, the seller ships it to your agent's warehouse in China. Once it arrives, the warehouse staff takes photos of the item and uploads them to your account. These are your QC (Quality Check) photos.
QC photos serve one critical purpose: they let you inspect the actual item before committing to international shipping. If something is wrong, you can return it to the seller while the item is still in China. Once you ship it internationally, returns are essentially impossible.
What Your Agent Provides
Standard QC photos (free):
- 3-8 photos per item
- Overall front, back, and side views
- Tag or label photo
- Close-up of key details (logo, print, etc.)
Additional photos (paid, $0.30-1.00 each):
- Specific angle you request
- Close-up of stitching, materials, or problem areas
- Measurement photos (item next to a ruler/tape measure)
- Weight photo (item on a scale)
When to Request Extra Photos
Request additional photos when:
- You cannot tell a detail from the standard photos (logo too blurry, angle too far)
- The item is expensive and you want to be thorough
- You spotted something suspicious and want a closer look
- You need measurements to verify sizing (check our Chinese size chart guide)
Do not request extra photos when:
- Standard photos clearly show the item is good
- The item is very cheap ($5-10) and return shipping would cost nearly as much
- You are buying basic items (plain t-shirts, socks) where QC barely matters
How to QC Sneakers: Step-by-Step
Sneakers are the most QC-intensive items because they have the most details to check. Here is how to inspect them systematically:
Step 1: Overall Shape and Silhouette
Hold the QC photo next to a retail photo of the same shoe. The overall shape should match:
- Toe box shape — Is it the right roundness/squareness for the model?
- Heel height and shape — Does the back curve match retail?
- Midsole height — Is the sole the right thickness?
- Overall proportions — Does anything look disproportionate?
Shape is the hardest thing for reps to get right and the most noticeable flaw on foot. If the shape is significantly off, RL immediately.
Step 2: Check Both Shoes Match
Compare the left and right shoe:
- Height — Are they the same height? (slight differences are normal)
- Toe box — Same shape and angle?
- Swoosh/logo placement — Symmetrical on both shoes?
- Color — Same shade? (lighting can make them look slightly different)
Slight asymmetry is normal even in retail pairs. Major differences (like one swoosh being clearly higher than the other) warrant an RL.
Step 3: Logo and Branding Details
Check brand-specific details:
- Nike Swoosh — Correct shape, size, placement, and stitching around edges
- Jordan Wings logo — Correct size, placement, and font
- Adidas stripes/trefoil — Correct width, spacing, and symmetry
- New Balance "N" — Correct size, placement, and stitching
- Any text or numbers — Correct spelling, font, and placement
Step 4: Stitching Quality
Look at the stitching throughout:
- Even spacing — Stitches should be consistently spaced
- Straight lines — No wavy or crooked stitch lines
- No loose threads — Cut threads should not be visible
- Color matching — Thread color should match the material it is on
- Double stitching where expected — Many shoes have double-stitched seams
Step 5: Materials and Texture
Assess the materials visible in photos:
- Leather — Should have natural grain, not plastic-looking
- Suede — Should look soft and textured, not flat or shiny
- Mesh/knit — Should have consistent weave pattern
- Rubber sole — Should be clean and even
- Paint/coloring — No bleed or uneven application
Step 6: Sole and Midsole
Check the bottom and sides:
- Sole pattern — Matches retail tread pattern
- Midsole color — Correct shade (common flaw: too yellow or too white)
- Glue marks — Minimal or no visible glue around the sole edge
- Air units (if applicable) — Correct size, placement, and transparency
Step 7: Box and Extras
If you care about the full package:
- Box label — Correct size, style code, and color name
- Extra laces — Included if the retail pair comes with them
- Hangtag — Present if expected
How to QC Hoodies and Clothing
Clothing QC is generally simpler than sneakers but still important:
Print and Embroidery Check
- Placement — Is the print/logo centered? Is it the right distance from the neckline?
- Size — Is the print the right size compared to retail? (too small and too large are both common flaws)
- Quality — Is the print sharp or blurry? Are colors vibrant or faded?
- Alignment — Is the print straight or tilted?
- Embroidery — Are the stitches clean and dense? Are letters correctly shaped?
Fabric and Material Check
- Weight — Does the fabric look appropriately thick/thin? (request a weight photo if unsure)
- Color — Accurate compared to retail? (warehouse lighting can make colors appear slightly different)
- Texture — Does the material look right for the brand and item?
Construction Check
- Stitching — Even, clean, no loose threads
- Seams — Straight and properly aligned
- Tags — Correct brand tags (neck tag, wash tag, size tag)
- Drawstrings — Correct color, material, and tips
- Zippers — Correct brand (YKK on many high-end brands), smooth operation
Sizing Check
- Request measurement photos if you are unsure about sizing
- Compare against the size chart on the product listing
- Check our Chinese size chart guide for conversion tips
How to QC Bags
Bags require attention to hardware, alignment, and materials:
Alignment and Symmetry
- Pattern alignment — On monogram bags, the pattern should align across seams
- Stitching alignment — Stitch lines should be parallel and evenly spaced
- Hardware placement — Buckles, clasps, and chains should be centered and symmetrical
Hardware Quality
- Color — Gold hardware should be the right shade (not too yellow or too brassy)
- Weight — Hard to tell from photos, but cheap hardware looks thin and flimsy
- Engravings — Brand engravings should be clean, centered, and the correct font
- Zippers — Should show brand name, pull smoothly
Material Quality
- Leather grain — Should look natural, not plastic
- Canvas — Should have the right texture and sheen
- Lining — Interior lining should be the correct color and material
- Edge finishing — Leather edges should be painted or burnished cleanly
Shape and Structure
- Overall shape — Compare to retail photos from the same angle
- Base shape — Should sit flat and be symmetrical
- Handles/straps — Correct length, width, and attachment
Understanding Warehouse Lighting and Photo Quality
One of the biggest challenges with QC photos is that warehouse lighting does not perfectly represent how items look in person. Here is what to know:
Common Lighting Issues
- Colors appear slightly off — Warehouse fluorescent lighting can make whites look yellowish, blacks look grayish, and colors look more muted
- Texture is hard to see — Flat lighting can make textures look smoother or rougher than they actually are
- Small details are blurry — Standard QC photos are taken quickly. Small text or fine stitching may be hard to read
- Reflective materials look different — 3M, patent leather, and metallic materials photograph differently under warehouse lights
How to Account for Lighting
- Do not obsess over exact color matching — A slight color difference in photos often disappears in person
- Focus on relative colors — If one part of the shoe should be lighter than another, check the relationship rather than the exact shade
- Request natural light photos — Some agents offer this for an extra fee. Worth it for color-critical items
- Ask other buyers — Community QC posts often show items in both warehouse and natural lighting
QC Resources and How to Use Them
Retail Reference Photos
Before QC'ing anything, find retail photos of the exact colorway and style:
- Official brand websites
- Retailers (Foot Locker, SSENSE, Mr Porter)
- Sneaker databases (StockX, GOAT, Grailed) for photos of authenticated retail pairs
Community QC Posts
Check community QC posts of the same item from the same seller:
- Other buyers' QC photos show what to expect
- You can compare your pair to theirs to spot variations
- Comments often highlight specific flaws to look for
Batch Information
Knowing which "batch" your item comes from helps with QC:
- Different batches have different known flaws
- Community guides often list batch-specific issues
- Check our batch flaws guide for common issues by batch
How Long Should QC Take?
Here is how long QC should take for each item type:
| Item Type | QC Time | Notes |
|---|---|---|
| Plain t-shirt | 30 seconds | Check print/logo, color, size tag |
| Branded hoodie | 2-3 minutes | Check embroidery, tags, overall quality |
| Sneakers | 5-10 minutes | Most detailed QC needed |
| Bag | 5-10 minutes | Check hardware, alignment, materials |
| Accessories (belt, hat) | 1-2 minutes | Quick check of branding and quality |
Do not rush QC, but do not spend hours agonizing either. After a few hauls, you will develop an eye for it and the process becomes much faster.
When QC Does Not Matter (Much)
For some items, extensive QC is overkill:
- Basic plain items — A plain black t-shirt or unbranded shorts. As long as the right size and color arrived, you are good.
- Very cheap items ($3-5) — The return shipping might cost more than the item. Unless it is completely wrong, GL it.
- Items with simple designs — A t-shirt with a small chest logo has fewer things that can go wrong than a complex all-over print.
- Socks, underwear, basic accessories — Quick glance is sufficient.
Save your detailed QC energy for:
- Expensive items ($30+)
- Items with complex branding or detailing
- Sneakers (always QC sneakers thoroughly)
- Bags (always QC bags thoroughly)
- Items you plan to wear frequently and visibly
Building Your QC Skills Over Time
QC is a skill that improves with practice. Here is how to get better:
- QC every item — Even items you are 90% sure are fine. The practice builds your eye.
- Study retail pairs — The more familiar you are with how retail items look, the faster you will spot flaws.
- Read community QC posts — Other people's analysis teaches you what to look for.
- Compare your in-hand items to QC photos — When your haul arrives, compare the items to the QC photos. This teaches you how warehouse photos translate to real life.
- Do not be afraid to ask — Post your QC photos in community forums if you are unsure. Experienced members are usually happy to help.
After 5-10 QC sessions, you will be able to GL/RL most items within seconds. It becomes second nature.
