I've noticed that there's currently some kind of manufacturing consent going on in the EU, presumably preparing the population for, which I claim, plans to make it very difficult for European consumers to order from China directly.

Disclaimer: I gladly buy from local EU businesses, but not if they're just a middleman charging an unreasonable fee for importing Chinese-made products.

userbinator•6h ago
The EU and US have historically been very much opposites, and now increasingly more so, when it comes to things like this.
cjbgkagh•8m ago
The US is gearing up for a China conflict, there is a split between the prep for war with China now or sort out Iran first and then prep for war with China. It’s currently most obvious in the MAGA split but the dems are captured as well. AOC is signaling she’ll play ball in what I assume is prep for a presidential run.

Like most voters I’m anti-war but people tend not to get what they vote for in important matters like that.

The US will not permit the EU to sit on the sidelines.

Sloowms•6h ago
Manufacturing consent has a different meaning. Politicians are always going to argue for their case but that is not the same as how the media and business monopolies in the US have fried the US public on everything. The EU is of course going to start cracking down on imports of goods that do not follow EU law and the platforms that sell these products.

I saw an electronic scooter in a shop here in Slovenia, but the name of the brand was unknown to me, and the price was quite high. (1500 EUR!)

I searched the brand on the internet, but nothing turned up. Just Slovenian shops selling that same model at a similar price. [1] This seemed strange to me.

So then I screenshot one of those pages and search via image. Turns out that you can buy the exact same scooter on TaoBao for 952 RMB. (~114 EUR.) [2]

This is an absolutely ordinary situation. It was much the same when I was purchasing a bike for my kid -- 300 EUR here vs. 250 RMB there, for exactly the same bike. The purchasing power gap between USD|EUR and RMB is immense.

(I try not to talk about it too much, because it's the sort of thing that really upsets politicians and local vendors, and they'll want to find a way to make it more painful. It's a secret "life-hack" but for real.)

A friend of mine scoffed that I would buy a remote controlled 12v relay for $4 from temu. He said I was risking burning my truck to the ground to save $30. He sent me a link to the Amazon one he bought. So I sent him a link to the exact same one, on Temu, for $5.

Relays are one thing that you notoriously can't trust what it looks like. Yes, the one your friend bought on Amazon was probably also junk, but you should definitely buy components like this from a reputable vendor unless their application is absolutely trivial.

Shoes are another one. I picked up some Crocs knock-offs for about $10 a few years ago, and they're probably the best sandals I've ever had - still going strong. I suspect it's not even a 'knock-off' but simply people who run the manufacturing lines continuing to run the manufacturing lines after the official order is filled and shipped back to the West to be sold at lol markups.

Low quality Chinese plastics are known to contain heavy metals like lead or cadmium. I would never trust a random Chinese manufacturer that isn’t vetted by a much larger organization that I can actually sue for negligence, etc.
fy20•42m ago
This is the same for almost all electronics. If you buy a toaster, how much do you think it really costs to manufacture the €20 no name brand vs the €80 Delonghi branded one? In both cases, the price the customer pays is many multiples higher than the manufacturing cost.

This is why these Chinese sellers have become so popular - although in some cases, yes they are cutting corners - the main reason why they can sell the products so much cheaper is because they cut out a number of middlemen.

The person who imports the product into Europe has to make a profit. The person who brings it from there into your country and distributes it has to make a profit. The retailer has to make a profit, on top of paying their staff and landlord. It all adds up.

esperent•13m ago
I run a business in Vietnam, and it's often hard/prohibitively expensive to purchase recognizable brand name items so we end up purchasing lots of these unbranded/rebranded Chinese items. The quality varies wildly and there's no way to know ahead of time.

I would always recommend buying recognizable brands for anything critical. Otherwise it's basically a lottery. Quality control for brands, not to mention customer support, might feel like it leaves a lot to be desired. But it's still light years ahead of un/rebranded Chinese goods.

Since we have no choice, and the odds of coming out ok (if not exactly winning) in this lottery are not that bad, it's a workable situation. But because we have to replace things so often, I'd say we don't save much money - compared to western prices for the brands I mean. Compared to Vietnamese prices, we definitely save money. I'm not happy about the waste created, but at least we're in the country where everything goes to get recycled already.

On the other hand, there are also good quality Chinese brands (Dong Chen power tools, for example, or Timemore coffee equipment). But they're not that cheap.

concinds•5h ago
If popular goods disobey safety regulations, it was bound to catch authorities' attention at some point. But:

> they're just a middleman charging an unreasonable fee for importing Chinese-made products

Doesn't most of our economy feel like a scam?

It seems inevitable, when dominant economic frameworks treat consumption as something which must be endlessly stimulated (at ever-increasing prices), instead of stimulating production, forcing cutthroat competition in areas where there is currently little, and letting the unprofitable rent-seekers and parasites get flushed out.

cjbgkagh•15m ago
> Doesn't most of our economy feel like a scam?

Yeah, it’s an institutionalized scam that’s increasingly dysfunctional and absurd.

It’s only cutthroat capitalism for the less well off majority that make up an increasingly small part of the economy. By dollar value the economy is dominated by financialization and speculative asset bubbles.

TazeTSchnitzel•36m ago
This feels like a necessary evil when it is often cheaper to buy an entire Chinese product directly with free shipping than to pay for just the domestic shipping of anything at all. This is a market distortion which has a huge cost to the environment among other things.

On the other hand China is the manufacturing giant of the world, and being able to source components directly in small quantities at a reasonable price is probably very useful to small businesses, so I hope that can continue somehow.

ozim•7h ago

I buy some arts materials from China, but only simple things that I cannot find in EU or tyat are just the same product re-sold a lot more expensive here. I'd be glad to buy in EU if that's cheaper.

I still buy EU arts materials that are more expensive than Chinese products, but that are (at least supposedly) better tested for toxicity.

I noticed in the past year or two art stores like Casa Piera/Arte Miranda have had more products like watercolor paper and paints from China. I hope new regulations will make sure these are compliant with EY regulations, without raising the price to consumer too much.

mschuster91•6h ago
The key thing is: Europe has product standards (and not just on safety), sometimes very strict ones. We have democratically agreed upon these, often enough only as a response to the industry being unable or unwilling (cough Apple and USB-C) to do the right thing on its own. In addition, we have warranty requirements (a minimum of two years), minimum wage and workplace safety regulations.

Now Temu, Shein, lots of the shops on Alibaba, Amazon and eBay... they all push stuff into Europe that violates these standards and can be sold cheaper as a result.

That is bad on three sides: First, for the dangerous stuff (such as the toys with choking hazards, lead paint or the "chinesium" Big Clive routinely pulls out of shady eBay sales), that's directly endangering our people and/or our environment. And second, all the stuff made and imported that violates requirements is undercutting our domestic production and economy who does have to follow the regulations or otherwise it gets fined. And finally: a lot of the stuff particularly on Temu and Shein is outright garbage, falling apart after a few uses - and then it ends in our landfills and waste disposals. A horrible waste from an environment perspective, especially given that a lot of the junk comes in via air freight of all things!

palata•6h ago
> they all push stuff into Europe that violates these standards and can be sold cheaper as a result.

I understand that and I agree that it should be regulated. But on the other hand, I can order 50 zippers on Temu for 2$, and if I go to a local store they sell one for 10$. I bought both, and they are exactly the same.

So one zipper on Temu costs 4 cents, versus 10$ in a local store. That's 250x more expensive. Doesn't seem reasonable.

mschuster91•6h ago
> I bought both, and they are exactly the same.

They are not. With the one you buy at your local store, you get the two years warranty, and should the thing contain, say, lead paint you can hold the seller accountable.

Good luck doing the same against Temu.

In addition, you pay a markup at the physical store for stockkeeping. Yeah sure, I can order the small capacitor for some fried PLC adapter on Amazon. No doubt. But I'll need to wait about two days for shipping, whereas the local electronics store has it right now when I need it.

palata•6h ago
> They are not. With the one you buy at your local store, you get the two years warranty

And with the Temu one I get 250 units for the same price. I don't know how often you break a zipper, but 250x in two years sounds like a lot :-).

> should the thing contain, say, lead paint you can hold the seller accountable.

I understand what you are saying, but honestly I doubt they check every 10cm of every zipper for traces of lead (or other). If there is ever an issue, maybe (?) they will recall them somehow, but I probably won't ever know (say I paid cash, they don't have a way to contact me at all, and with a credit card I'm not sure if they can / will find my contact ever).

> But I'll need to wait about two days for shipping, whereas the local electronics store has it right now when I need it.

Sure! But the fact is that I'm absolutely fine waiting 2 days if it costs me 250x less. Actually with Temu it's more a few weeks, I would think? Still worth it for zippers.

If the zipper was sold for 1$ in the local store, that would be different. But 10$? At this point I just don't want the zipper at all. So in a way it's not really "Temu vs local store". If I don't get it on Temu, I don't get it at all.

jabjq•6h ago
Just to be clear those things you buy on Temu must have by law a representative in the EU which would be the entity responsible if you are poisoned by whatever you buy.

Also: fuck local merchants. They have scammed us for a lifetime. They can all close for all I care.

mschuster91•5h ago
> Just to be clear those things you buy on Temu must have by law a representative in the EU which would be the entity responsible if you are poisoned by whatever you buy.

Yup, the "EC Representative". Some LLC paper company that's probably going to just fold over when you hit them with a claim.

StrLght•5h ago
So you're saying that existing regulations don't work, so we should fix it by adding more regulations? What if they also won't work?
_zoltan_•46m ago
for 250x price difference I don't care about the warranty.
StanislavPetrov•44m ago
>With the one you buy at your local store, you get the two years warranty, and should the thing contain, say, lead paint you can hold the seller accountable.

I'm not sure how it works in the EU, but here in the USA I'd guess that the vast majority of those zippers are just ordered from Temu and marked up. And good luck holding the "seller accountable" if the zipper doesn't end up meeting your standards.

_Microft•6h ago
How do you tell that you did not get any from a lot that was dyed/painted with a cheaper but toxic color?
palata•5h ago
Are you saying that the local merchant tests it and that's why they sell it at 250x the price?

I said 10$, but it depends on the length. So 60cm is maybe 10$, 70cm is 12$, 80cm is 13.50. So you would say that testing the 70cm variant of the zipper is worth 2$ more than testing the paint on the 60cm variant?

My point is that at this price, if I don't get the zipper on Temu, I don't get it at all. I won't pay 10$ for a zipper of this quality.

throwawaylaptop•4h ago
I've noticed a similar 'this profit margin seems almost vulgar' on the same store shelf.

As you showed with slightly longer zippers.. I notice with car fob remote batteries. An 8 pack is $12 at the store. The same brand, a single will be $5. A 2pack is $7. And the 8pack $12. Do you really need to make $4 on selling me a single? I know shelf space is valuable, but the same store sells things for $1 too on another shelf so apparently <$1 profit shelf space is possible.

mook•1h ago
Given how small the batteries are, they probably have similar costs for shipping and handling. So there's a cost to get _anything_ to the local store, plus the cost of the actual goods.
Aeolun•46m ago
Maybe the one in the local store wouldn’t need to be $10 if more people bought them there? Also, they need to charge for the risk of putting the crap on the shelf without testing it first.
zorton•6h ago
Was there a vote on what the correct drawstring length should be? How about a vote on the person who wrote those regulations specifying the length?
mschuster91•6h ago
We vote on the representatives, who in turn spend an awful lot of time talking to all sorts of interest groups - manufacturers, other parts of the economic chain, consumer and environmental protection organizations, lawyers, industry organizations, god knows what else - and in the end usually come up with decent regulations as a result.

I agree that the results can be sometimes weird, sometimes annoying, and sometimes outright dumb. But I'll rather pay that price than not have USB-C, two year product warranties, no lead in kids' toys or access to clean and safe drinking water.

lousken•6h ago
what about garbage from amazon, aliexpres and others?
pndy•6h ago
That's my question as well. If he's so concerned about this then what about other services? Polish Allegro quite recently had to add a filter on their site to sieve out all sellers from outside EEA because they flooded it.

Moreover, there are physical stores that also sell this "dangerous" stuff. My friend worked in one and she complained all the time on chemical odour these items were generating.

shivasaxena•5h ago
Then your friend is free to not buy these goods she deems "dangerous".

Why stop those of us who want to buy it?

wat10000•5h ago
Because I want to be able to just buy stuff, not have to spend hours researching whether some trinket is going to poison me.

I’d be ok with dangerous products being available for purchase if they’re labeled as such.

throwawaylaptop•4h ago
Just shop at higher end stores. If I want to gamble and search for an item I go to Temu. If I want good enough, I go to value based US retailers. If I want 'a bit better' I go the slightly more expensive ones known for curating their for sale items a bit. If I want quality, I go to a specialty shop and ask a sales representative for the desired quality.
john01dav•1h ago
There's no guarantee that something is better just because it's more expensive or has marketing that says that it's better. Specialist knowledge and quite a lot of time is required to properly evaluate a product. Consider that Amazon is full of questionable products. I have also seen non-UL-listed (or listed with anyone else) phone chargers in physical stores in the united states. You can't rely on reputation either in an age of enshittification.
fooker•6h ago
The issue is the complete lack of enforceability.

A regulator can tell temu/shein/amazon/etc to take down the seller, or even the brand and the next day two new ones prop up selling the product from the same factory.

To my knowledge, no one has solved this yet. Maybe a good use of AI? Unfortunately not monetizable really.

If that game remains afoot for too long, the buck stops at the distributor - who can't hide from the EU behind ever-shifting randomly generated brands.

bluGill•6h ago
temu just ships in a plain bag/box and customs would have to open ever package to know what is in it. They rarely have enough people for that.
lazide•6h ago
That’s when customs blocks small shipments, or as they recently did, start charging tariffs on everything - no more de minimis.

Then it only makes sense to do larger shipments to distributors, and those are easier to track and intercept.

But it’s not like the war on drugs every succeeded, and that never had to worry about economic viability.

mook•1h ago
They might have to say anything from Temu is banned. No need to open the box, just check the shipper.
somenameforme•48m ago
And you've just created a nice rich industry of 're-shippers.' Though come to think of it, that's already essentially what drop shipping is.
fooker•5h ago
I don't disagree. The question is how they'd do it.

There's an interesting dilemma here you're not considering. Any more red tape here would make it extremely difficult for legitimate small businesses to sell anything online.

Simple solutions that you have just thought about usually don't work, especially when the topic seems like it might employ several researchers and lawmakers.

wat10000•5h ago
It’s trivial to solve. Make it so that the company that runs a store is liable for products sold in that store. Amazon will figure this out instantaneously if they’re actually responsible for damages. As long as they aren’t then they’ll continue to do nothing.
fooker•4h ago
Amazon is already liable for products that are 'fulfilled by Amazon'. It has not stopped this even a little bit.
wat10000•3h ago
Are they? I thought they'd managed to push off liability onto the seller.

I'm not a friend of EU regulators in general, but complaining about Chinese imports is an easy PR-win. If a country can compe up with something like "Gutter Oil" being a thing, procured by mom-and-pops, sold to restaurants nearby, which then shove it down the throats of their customers nearby, there must be such little accountability and remorse from the producer side in general in the PRC that putting more distance between vendors and customers can only result in more toxins. Europeans have no idea about the brazenness there.

"(...) kids’ shorts with drawstrings longer than regulation length (...)"

We really overrregulate things here in the EU. It was a great run, we've had access to great Chinese stuff for a while now. Maybe around 2007-ish the direct-to-consumer imports started.

It has really helped me to acquire tools and eletrical components cheaply, where no other supplier was able to offer it at a good price or at all. Hopefuly the EU will fail to keep this in check so that the party can continue.

edg5000•5m ago
The EU has this pathetic protectionist attitude. They are sore losers when it comes to manufacturing, energy and IT. With IT they are trying to bully these US companies all the time. With energy we've overregulated nuclear and are importing natural gas en masse, all while proclaiming to be green.

Instead of getting angry that other countries can do things better, we should focus on getting better ourselves! Get our energy, manufacturing and IT sorted out! This is pathetic.
