A batch is a production run. One factory, one set of moulds and patterns, one lot of materials, some quantity of finished units. That is the whole concept, and it is the single most useful idea in this hobby, because it explains why the seller you pick and the object you receive are only loosely related.
The same batch is bought and resold by dozens of middlemen. So the store decides your service — how fast they reply, whether they send extra photographs, what happens when something is wrong — and the run decides your item.
Why two of the same item are not the same
Ask why a shoe someone raved about arrived disappointing for you, and the answer is usually one of four things, none of which is the seller lying.
- A different run entirely. Large stores carry several versions of the same silhouette at several prices. You pick the price; you have picked a batch whether or not anybody said the word.
- A material lot. Leather, suede and knit yarn are bought in lots and lots differ. Two runs of one design, six months apart, are not made of the same stuff.
- A revision. Factories change things — a mould, a stitch count, a supplier — usually in response to complaints. A review of last year's version describes an object that may no longer be produced.
- Ordinary variance inside one run. Even within a single batch, units are not identical. This is what the QC photograph is for.
The first of those is a live and slightly awkward point. On a 2025 thread about a bad experience, another buyer's first suggestion was that the two of them had not bought the same thing:
He sells alot of different batches of each shoe. are you sure you didn't accidentally bought a not returnable cheap batch?

Whether or not that was the explanation in that case, the mechanism is real, and the thread it came from is an argument between two people who may not have owned the same object. "I bought it from the same store" is not the same claim as "I bought the same item".
A batch flaw is not a defect you can exchange away
This is the distinction that saves people money.
A defect is one unit going wrong: a skipped stitch, a glue smear, a scuff in transit. Send it back and the replacement is fine.
A batch flaw is in the pattern, the mould or the artwork. Every unit from that run has it. Requesting a swap gets you a clean example of the same problem, which is exactly what one buyer reported after exchanging a pair over a misplaced heel print:
I ordered a pair from sixgods using allchinabuy and had it exchange because the print on the heel is too low. The exchange pair has arrived but the issue is still the same.

So the question to ask before requesting an exchange is not "is this wrong" but "is this wrong on all of them". The batch guides exist largely to answer it: for each common silhouette they name the run the community rates highest and the flaws that run carries on every pair. Recognising a documented flaw in your own photographs is the difference between accepting an item knowingly and spending six more weeks discovering it twice. When it arrives covers the same split from the other end.
Batch names are marketing as often as they are facts
Batch codes started as shorthand between buyers and became a sales tool, so a name in a product title is a claim rather than a certificate. Our own batch data records the pattern in three forms: a well-regarded run marketed as a private "Tier 1" to imply exclusivity it does not have, a widely-criticised run relabelled with a better run's name, and one run resold under a house name so that buyers compare two things that are the same thing.
None of that is exotic fraud. It is a wholesale market where goods arrive unbranded and the name is added by whoever is selling them to you. Treat a batch code as a question to ask the seller, not an answer they have already given you.
Not everything has a batch scene
Sneakers do, and bags and watches are usually discussed by factory rather than by batch. Most apparel has neither. For a hoodie or a jacket there is frequently no codified run at all, just a seller, a price, and photographs — which is why the word gets used loosely, as a general marker of a good production run:
These look really clean man, shape and paneling are on point. Chipotle definitely killing it with this batch.
u/wingchicks, r/FashionReps, 27 August 2025
Where no batch scene exists, there is nothing to look up and QC photographs carry the whole weight. That is not a worse situation, only a different one, and pretending an apparel item has a famous batch behind it is a sales technique.
The record contradicts itself, and the dates matter
Batch consensus moves. A verdict from five years ago can be the exact opposite of the current one, and both were sincere:
Who even is cool kicks lmao but h12 is the best it’s all the same batch there’s not updated batch or nothing pk and ljr are worse and plus h12 is 55$
u/Alternative-Ad-2522, r/FashionReps, 18 May 2021
The batch guides on this site file H12 as the run to avoid on the two silhouettes that comment is about. We are not calling a stranger from 2021 wrong. We are saying that a batch opinion has a shelf life, that factories revise and decline, and that an undated recommendation is close to worthless.
Read the date on any batch claim before you read the claim.
What this site does and does not assert
Our batch data is a curated overlay, read out of community discussion. Nobody here has cut a shoe apart, visited a factory, or compared two runs side by side. It records what the community says, flaws and rebrands attached, and it is only as current as its last revision.
We also never roll any of it up into a rating of a seller. The voting method explains why: standing here comes from votes on items and nothing else, so a store that happens to resell a well-regarded run earns no credit from us for it.
