ACERCA DE ESTE EPISODIO
What happens when your manufacturer quietly replaces an approved component or material with a cheaper alternative, without telling you?
In episode 352 of China Manufacturing Decoded, Adrian and Renaud discuss unauthorized component substitutions, why they happen, and the risks they create for importers and product brands.
Sometimes factories make changes to reduce costs, respond to pricing pressure, or because product specifications were never clearly agreed upon. Other times, deliberate cost-cutting leads to quality fade, where materials and components are gradually downgraded without the buyer's knowledge.
The problem? A product might look identical and work perfectly when first tested, but fail prematurely, become non-compliant, or even create a safety hazard.
Topics covered:In this episode, we cover:
- Why manufacturers substitute components and materials without approval.
- How price negotiations and unclear specifications can contribute to unauthorized changes.
- The hidden reliability, compliance, and safety risks.
- How inspections, laboratory testing, and risk-based checks can uncover substitutions.
- What to do if thousands of products have already been manufactured using an unapproved component.
- Why smaller importers need practical controls and, where possible, backup suppliers.
- The additional risks of relying on an ODM manufacturer.
Not every alternative component is necessarily a problem. The real danger is allowing changes without proper evaluation, testing, and approval.
Listen to learn how to protect your products, customers, and business from unauthorized manufacturing changes.

TRANSCRIPCIÓN 🔗
00:00:03.237 --> 00:00:08.085
You're listening to China Manufacturing Decoded from the Sophies Group.
00:00:12.980 --> 00:00:20.162
Hello welcome back to episode 352 of the podcast today and renault joins me,
00:00:20.682 --> 00:00:25.122
and renault back in episode 339,
00:00:26.048 --> 00:00:31.122
which was a couple of months ago now we discussed price wars amongst chinese
00:00:31.122 --> 00:00:36.642
manufacturers and how pressure to reduce those costs leads to certain problems
00:00:36.642 --> 00:00:39.480
like quality fade And that,
00:00:40.130 --> 00:00:45.035
you know, might mean that factories are substituting materials or components,
00:00:45.279 --> 00:00:47.003
but doing it on the quiet.
00:00:47.351 --> 00:00:51.732
So that's the issue that I want to explore with you today in more detail.
00:00:51.732 --> 00:00:57.472
So why unauthorized substitutions happen and how buyers can uncover them and
00:00:57.472 --> 00:00:58.652
what they can do to prevent them.
00:00:59.122 --> 00:01:03.784
So is this something that you frequently see happening?
00:01:05.688 --> 00:01:08.822
It's something that every buyer is afraid of i'm sure right
00:01:09.700 --> 00:01:14.115
and it can take many forms if you buy
00:01:14.847 --> 00:01:19.672
electronic products i don't know maybe a i don't know tablet well you never
00:01:19.672 --> 00:01:24.084
know the spec you know of the whatever
00:01:24.794 --> 00:01:28.892
the memory how much memory you're going to have or how many megapixels of the
00:01:28.892 --> 00:01:30.320
camera and things like that
00:01:31.385 --> 00:01:33.562
if you buy i
00:01:34.980 --> 00:01:38.521
don't know like clothes well
00:01:39.264 --> 00:01:42.742
maybe they try to save by making everything a little bit smaller
00:01:43.342 --> 00:01:49.352
right or maybe they try to save by making a substitution such as it could be
00:01:49.352 --> 00:01:54.902
the main fabric let's say but the main fabric it's kind of easy to to catch you know
00:01:55.602 --> 00:02:01.402
but maybe some of the smaller accessories right buttons and so on it's not so
00:02:01.402 --> 00:02:04.659
much of a problem actually in garments but if you buy
00:02:06.947 --> 00:02:13.081
You know, yeah, pieces of steel that are used to do, I don't know,
00:02:13.081 --> 00:02:14.569
scaffolding, for example.
00:02:15.104 --> 00:02:21.061
Yeah, that, you know, they might use a cheaper grade, right?
00:02:21.061 --> 00:02:22.273
A cheaper grade of steel.
00:02:22.974 --> 00:02:26.962
Or they might just make it thinner and or shorter, right?
00:02:27.357 --> 00:02:33.384
Like, all of this is basically a way to cut costs. So
00:02:35.495 --> 00:02:43.454
it's not uncommon, let's say, when you deal with relatively small factories
00:02:43.959 --> 00:02:50.041
where maybe the owner or the owner's wife or the owner's cousin is buying the materials,
00:02:51.022 --> 00:02:53.082
trying to save for the family or something.
00:02:54.397 --> 00:03:00.431
Or in general with factories that are that tend to operate at the lower scale
00:03:00.431 --> 00:03:07.559
of prices in their industry so cost control is is the entire game basically
00:03:08.454 --> 00:03:11.020
of factories that are about to go out of business
00:03:12.516 --> 00:03:16.431
Well that that kind of led into my next question because i was gonna say all
00:03:16.431 --> 00:03:21.651
right if factories are making these changes why would they want to change something
00:03:21.651 --> 00:03:23.781
that's already been specified and approved.
00:03:23.781 --> 00:03:27.811
So you've mentioned cost being a major motivation.
00:03:27.811 --> 00:03:34.881
I mean, could it be because they believe that they've got a better alternative
00:03:34.881 --> 00:03:39.094
and they just don't feel the need to inform their customer, for example?
00:03:39.769 --> 00:03:46.311
Okay, there's a lot to unpack here. First, you said something that has been
00:03:46.311 --> 00:03:50.762
specified and approved, it's not always the case, okay?
00:03:52.309 --> 00:03:59.803
Professional buyers will make sure that things are specified black and white
00:04:00.279 --> 00:04:05.317
you know referred to in some kind of contract or po etc etc okay
00:04:06.206 --> 00:04:14.908
smaller buyers maybe less organized buyers may not cross every t and dot every i so
00:04:15.937 --> 00:04:24.733
the factory might think they have a lot of freedom right so there's the first first
00:04:25.902 --> 00:04:29.745
first kind of issue here is that there might be a disconnect
00:04:31.437 --> 00:04:36.757
And sometimes that's really really really the wrong attitude the wrong approach
00:04:36.757 --> 00:04:42.377
but a buyer will come to China we're saying Wow you know we found a manufacturer they really
00:04:43.277 --> 00:04:46.367
could be a trading company right but they really know what they're doing they
00:04:46.367 --> 00:04:51.637
know the product inside out maybe they know Oh, you know, some of the big names in our industry,
00:04:52.177 --> 00:04:53.747
maybe they're working with them.
00:04:53.747 --> 00:04:56.750
You know, wow, that's amazing. I can learn a lot.
00:04:57.122 --> 00:05:02.187
And then their attitude becomes, well, you know, you know that.
00:05:02.187 --> 00:05:08.532
So just make sure it's acceptable in the market to, you know, where I sell the goods.
00:05:09.095 --> 00:05:13.651
And that is really the wrong way. Okay. That's really the wrong way.
00:05:14.537 --> 00:05:19.026
When you deal with, let's say, the average Chinese factory, do not do that.
00:05:19.415 --> 00:05:22.707
Okay, because then you cannot complain if they substitute. They say,
00:05:22.707 --> 00:05:24.597
well, you know, we tried this nicely.
00:05:24.937 --> 00:05:29.800
Let's try something else. Yeah, we believe it's fine too, right? Very bad.
00:05:31.517 --> 00:05:35.371
After that, you said, why would they make a change?
00:05:35.557 --> 00:05:43.120
Well, sometimes the customer themselves say, hey, we need to cut the price that we pay you, you know.
00:05:44.817 --> 00:05:49.987
Again, that could be a disconnect where the supplier might...
00:05:51.356 --> 00:05:59.018
They wrongly understand, find a way to make it cheaper so that the price can be lower. Okay?
00:05:59.460 --> 00:06:01.659
But the buyer doesn't say it this way, but that's, you know,
00:06:01.659 --> 00:06:06.559
that's the way it's perceived. Well, in their mind, it's, you know, it's simple.
00:06:07.166 --> 00:06:11.729
You know, you want to pay lower price, you know that quality cannot be the same,
00:06:11.729 --> 00:06:12.919
right? It's pretty obvious.
00:06:13.244 --> 00:06:16.082
There's a high context culture, right?
00:06:17.059 --> 00:06:20.865
What's his name? Ofstader would say. so
00:06:21.956 --> 00:06:25.459
if the buyer doesn't clarify the context
00:06:26.141 --> 00:06:30.499
it is assumed you know that the receiving party is responsible for providing
00:06:30.499 --> 00:06:36.779
the missing context so okay you want to pay more well it means you're okay with
00:06:36.779 --> 00:06:40.591
you know cheapening the product a bit yes
00:06:41.238 --> 00:06:43.961
That's a subtle distinction isn't.
00:06:44.839 --> 00:06:51.606
It Yeah, right. And from what I read, if you then sue the supplier in China,
00:06:52.889 --> 00:06:59.210
and you happen to be in a court with a Chinese judge, they might say, well, that's fair.
00:06:59.524 --> 00:07:01.840
Yeah, you know, nothing bad with that, right?
00:07:02.639 --> 00:07:06.546
Or at least they would receive it as a valid argument, let's say, at least.
00:07:06.952 --> 00:07:10.263
So be very clear, right?
00:07:10.466 --> 00:07:15.522
If you say it's got to be cheaper, or if you say, I know the exchange rate is
00:07:15.667 --> 00:07:19.278
getting unfavorable, or I know that the materials are getting more expensive,
00:07:20.808 --> 00:07:26.637
you know, memory cards these days, you know, memory chips, right? Or a lot of other things.
00:07:27.194 --> 00:07:30.143
But I cannot pay more than X, right?
00:07:30.463 --> 00:07:35.288
Basically, you're telling the supplier, what you're thinking is,
00:07:36.228 --> 00:07:41.739
just find a way within your own operations to get some efficiencies maybe squeeze
00:07:41.739 --> 00:07:43.119
your own suppliers on price
00:07:43.827 --> 00:07:48.199
I don't care if you make a profit I cannot pay more than that that's it but
00:07:48.199 --> 00:07:52.674
the product must stay the same right but what they receive
00:07:53.399 --> 00:07:55.839
on their side on the receiving end is oh
00:07:57.746 --> 00:08:05.008
Cheapening of the product you know yeah then let's try to find something that
00:08:06.164 --> 00:08:12.389
is reasonable you know if they want to pay 10 less let's cheapen the product
00:08:12.389 --> 00:08:16.289
by about 10 but you know not more than that because it's not fair
00:08:16.889 --> 00:08:22.452
right i don't uh depends on what kinds of gains they might play or might what
00:08:22.649 --> 00:08:23.781
what kind of reasoning they might have
00:08:25.389 --> 00:08:35.169
another thing that might happen also is that some Chinese suppliers are what
00:08:35.169 --> 00:08:39.824
I would say are not reliable suppliers, not suppliers you want to deal with.
00:08:43.675 --> 00:08:47.349
They kind of play games and maybe they are a little bit like gamblers.
00:08:47.749 --> 00:08:51.732
There's always bad apples in every market in every country, right?
00:08:52.017 --> 00:08:59.829
So I'm really not knocking on Chinese but there's something that sometimes we can find and they will
00:09:00.770 --> 00:09:05.889
knowingly cheapen the product even if the cost of the materials is not going
00:09:05.889 --> 00:09:13.541
up even if the customer is not pushing them or whatever right they will try to cheapen the product
00:09:14.116 --> 00:09:17.447
just to find the limit okay and that's
00:09:18.830 --> 00:09:23.443
that's something that what's the author's name Paul Midler yeah Paul midler
00:09:24.115 --> 00:09:26.679
explains in his second book what's
00:09:26.679 --> 00:09:29.859
wrong in china so if you want to have a kick you can you can read that
00:09:30.673 --> 00:09:39.429
and he says some factory bosses really hate the idea of leaving money on the table and so they will
00:09:40.338 --> 00:09:47.189
you know if you want i don't know a component with whatever 20 different i don't
00:09:47.189 --> 00:09:48.646
know layers let's say okay
00:09:50.241 --> 00:09:53.059
Then they would start with 20 because they think well the first time they're
00:09:53.059 --> 00:09:58.373
going to check okay and then they're like if 20 was okay 19 is going to be okay right
00:09:59.237 --> 00:10:03.754
and then next time they didn't say anything if 19 was okay then 18 is okay right
00:10:04.305 --> 00:10:08.970
maybe we'll go directly to 17 because yeah they're not checking now we know right
00:10:09.841 --> 00:10:16.500
and then at one point the customer might come back and say hey you know you're cheating us all right
00:10:17.688 --> 00:10:21.699
but and then maybe oh sorry yeah whatever, I'll give you a discount for next time,
00:10:22.599 --> 00:10:24.340
made a mistake, blah, blah, blah, right?
00:10:25.153 --> 00:10:30.999
And then they're like, ha, so they cannot accept 15, but like 17 was okay,
00:10:31.319 --> 00:10:33.908
right? So they want to calibrate it.
00:10:34.146 --> 00:10:37.212
Okay, so there's always bad apples on every market, right?
00:10:37.560 --> 00:10:42.529
And in China, sometimes it takes this form, so you got to be careful.
00:10:42.698 --> 00:10:47.927
And that's what Paul Midler also is the one who wrote in 2007, I believe,
00:10:48.368 --> 00:10:54.344
after the mattel lead paint you know lead paint on toys that that big scandal
00:10:54.703 --> 00:10:58.709
he wrote an article where he explained okay this is what you know i would call
00:10:58.709 --> 00:11:00.810
quality fade is where they knowingly
00:11:01.175 --> 00:11:05.802
basically cheapen the product right and in most cases cheapening the product is
00:11:06.929 --> 00:11:09.129
buying cheaper components or materials
00:11:10.372 --> 00:11:11.957
yeah i'll leave that's what i'm in mind
00:11:12.421 --> 00:11:17.139
I'll leave links to these in the show notes right you mentioned checking and
00:11:17.139 --> 00:11:19.810
we're going to come on to that in a couple of minutes but,
00:11:21.169 --> 00:11:24.316
a kind of obvious question here right but some,
00:11:24.914 --> 00:11:30.779
buyers they might be thinking well if my manufacturer has given a replacement
00:11:30.779 --> 00:11:36.332
component for example which looks identical the finished product still works so,
00:11:36.979 --> 00:11:38.607
why should i be so worried about that,
00:11:39.695 --> 00:11:42.499
yeah, maybe cosmetically, that's the truth.
00:11:42.839 --> 00:11:47.394
However, I think that you would strongly suggest that that's not the right attitude.
00:11:48.971 --> 00:11:55.132
Well, first, if they are in a highly regulated industry, you know,
00:11:55.132 --> 00:11:56.952
they're going to get into big trouble.
00:11:57.272 --> 00:12:03.272
Try to do that with automotive parts or medical devices or something like that
00:12:03.272 --> 00:12:05.300
is really not going to fly. Okay.
00:12:06.710 --> 00:12:11.673
Now, let's say it's consumer products, not highly regulated.
00:12:13.303 --> 00:12:17.512
It really depends. If you have, I don't know,
00:12:19.230 --> 00:12:24.252
Some mechanical gears, let's say, and then they're supposed to be made in an
00:12:24.952 --> 00:12:30.482
engineering plastic that's really going to withstand whatever,
00:12:30.482 --> 00:12:33.742
10,000, let's say, cycles. Okay, fine.
00:12:34.247 --> 00:12:39.812
But then suddenly you chippen it, you use some, let's say softer plastic that,
00:12:40.252 --> 00:12:43.088
oh, I should not say softer, but plastic that will
00:12:43.983 --> 00:12:49.874
degrade much faster under the force of the moving parts.
00:12:50.228 --> 00:12:55.602
And suddenly after 100 cycles, you already start to, you know,
00:12:55.602 --> 00:12:59.730
to see there are problems and then it just suddenly doesn't work at all.
00:13:00.897 --> 00:13:05.632
So that really causes an issue with the reliability of the product,
00:13:06.038 --> 00:13:11.492
and you might have a lot more bad reviews, warranty returns, etc.
00:13:13.136 --> 00:13:19.166
There's so many examples. You use, I don't know, maybe a motor or
00:13:20.930 --> 00:13:28.310
Maybe just some electrical parts that have a certain rating and supposed
00:13:29.650 --> 00:13:38.400
to function as expected within a certain load, let's say, and then you degrade them.
00:13:38.400 --> 00:13:46.692
Well, the product might break very early or it might break after three months, okay?
00:13:47.396 --> 00:13:56.040
The product might also become critically unsafe if these parts were actually
00:13:56.040 --> 00:13:58.050
safety-critical parts, right?
00:13:58.827 --> 00:14:06.420
And non-compliant also, right? So if it can lead to a failure that can lead
00:14:06.420 --> 00:14:08.635
to a safety hazard, basically.
00:14:09.152 --> 00:14:12.287
That's pretty serious. Okay, pretty serious.
00:14:12.513 --> 00:14:18.092
And just to go back to the example of Mattel, the toy company in 2007, well,
00:14:19.090 --> 00:14:26.100
their supplier was using paint with lead because I guess it's cheaper and also
00:14:26.100 --> 00:14:29.681
it dries much faster, so it's more convenient, right?
00:14:30.105 --> 00:14:35.441
What happened? Like major recall, you know, millions and millions of dollars
00:14:36.078 --> 00:14:42.522
wasted plus a big hit to the brand and we're still talking about it now 20 years later right?
00:14:42.760 --> 00:14:43.729
I'm sure they're so pleased.
00:14:45.292 --> 00:14:53.496
So yeah right so it really depends on on what it is right imagine you buy a
00:14:53.496 --> 00:14:57.823
car and then oh you know they just changed something about the brakes
00:14:59.048 --> 00:15:04.486
or the airbags right and well you'll be pleased right well sometimes consumer
00:15:04.486 --> 00:15:10.586
goods can also come with their own safety hazards and now you you you really
00:15:10.586 --> 00:15:12.530
don't want anybody to mess with that
00:15:12.902 --> 00:15:17.426
Sure yeah so that's important advice to heed so just now you're talking about
00:15:17.426 --> 00:15:22.396
checking right and if some buyers aren't checking maybe that gives a bit of
00:15:22.396 --> 00:15:26.723
a longer leash to manufacturers to play games and that's that was the point you were making,
00:15:27.659 --> 00:15:33.026
what sort of checks can we do to discover unauthorized changes such as those
00:15:33.026 --> 00:15:34.015
that we've been mentioning.
00:15:34.920 --> 00:15:44.458
Well you need to start as usual from a risk analysis and how these issues could be uncovered.
00:15:44.911 --> 00:15:51.024
Sometimes it's a simple inspection before shipment, right? And we found so many of these issues.
00:15:51.715 --> 00:15:55.336
And the customer is sometimes totally shocked, like, what could I do?
00:15:56.596 --> 00:16:00.816
Everything's been made already, maybe, you know. But at least it's not shipped yet.
00:16:01.543 --> 00:16:04.526
Hopefully you haven't paid most of what you owe the supplier,
00:16:04.526 --> 00:16:06.344
so you still have some leverage.
00:16:07.935 --> 00:16:11.981
Otherwise, you might need to pick some samples, send them for testing.
00:16:12.532 --> 00:16:20.480
Same thing, right? Suddenly, oh, they're doing PCB assembly in a S&T shop that
00:16:20.863 --> 00:16:26.518
still uses lead-based solder paste. Ouch.
00:16:26.936 --> 00:16:32.799
Okay. Now the whole product is non-compliant to ROS, among others, right?
00:16:33.066 --> 00:16:38.188
So for some of that, you need to do some testing, right? It could be simple
00:16:38.188 --> 00:16:42.256
testing, like picking up on lead, or it could be more advanced testing.
00:16:42.813 --> 00:16:49.458
So, yeah, basically you need to keep track of it.
00:16:49.458 --> 00:16:54.288
In some cases, it might just be doing a quick WeChat call and saying,
00:16:54.288 --> 00:16:59.395
hey, go there and pick up this one and measure this and show me.
00:17:00.093 --> 00:17:01.338
In some cases, that works.
00:17:02.102 --> 00:17:06.838
If you have something very, very specific in mind, it reduces the risk a little bit, right?
00:17:07.111 --> 00:17:12.748
So you need to put filters in place to catch these issues from time to time, at least.
00:17:12.748 --> 00:17:17.408
You may not check everything all the time, of course, except if your production
00:17:17.408 --> 00:17:22.018
batches are pretty large or a lot of money, but you need to have some kind of
00:17:22.018 --> 00:17:23.708
plan basically based on risk.
00:17:25.084 --> 00:17:31.688
Yeah. And audits, inspections, some of the services that might help with this,
00:17:31.688 --> 00:17:33.888
that's something that we've been doing for a couple of decades.
00:17:33.888 --> 00:17:37.454
So do check out the website for those.
00:17:37.855 --> 00:17:43.888
If we are in a situation where the manufacturer has already made,
00:17:43.888 --> 00:17:47.608
you know, a bunch of units, thousands of pieces, right?
00:17:47.608 --> 00:17:52.350
And we find out that there's been a component substituted for whatever reason,
00:17:52.856 --> 00:17:57.383
this is kind of an emergency situation. How would you triage that? What would you do?
00:17:59.162 --> 00:17:59.649
Well,
00:18:02.609 --> 00:18:05.627
first you need to know the impact of that, right?
00:18:05.939 --> 00:18:12.732
Maybe it's only a small risk.
00:18:13.522 --> 00:18:18.030
And maybe in your market, you know, okay, we cannot use these products maybe
00:18:18.030 --> 00:18:23.123
for like this and this very discerning customers, but for the customers is okay,
00:18:23.500 --> 00:18:26.060
or we're just going to use it for ourselves or something like that.
00:18:26.526 --> 00:18:31.090
So in some cases, you could just say, hey, with a discount, we can buy it,
00:18:31.390 --> 00:18:33.925
you know, something like that.
00:18:34.186 --> 00:18:37.460
Or we just refuse the whole batch and you remake it. What do you prefer, right?
00:18:37.791 --> 00:18:44.020
If you still have a lot of leverage based on the status of payments and the
00:18:44.020 --> 00:18:49.577
contract and so on, then you can push a bit harder, right?
00:18:50.077 --> 00:18:53.723
They have to understand that, yeah, there should be a bit of a penalty.
00:18:56.050 --> 00:19:04.822
So that's one thing. If you really cannot take this product, then, well,
00:19:05.971 --> 00:19:10.388
I mean, if you cut it before shipment and before you send the whole payment,
00:19:10.899 --> 00:19:13.549
at least you haven't lost everything, right?
00:19:14.839 --> 00:19:18.218
But it might be a difficult conversation.
00:19:18.612 --> 00:19:23.222
And what happens to the products that they made, maybe under your brand,
00:19:23.616 --> 00:19:28.923
that you don't want to buy, are you going to ask them to get their destruction
00:19:28.923 --> 00:19:31.923
done and certified somehow?
00:19:32.563 --> 00:19:38.543
Are you going to witness that? Or are all these products going to go in Taobao or wherever?
00:19:39.361 --> 00:19:43.058
It's shipped to Pakistan and Nigeria.
00:19:43.643 --> 00:19:48.814
And then you can expect warranty requests from these countries you know
00:19:50.935 --> 00:19:57.053
yeah it can happen right especially if things don't seem to be fair so that's
00:19:57.053 --> 00:19:58.945
why communication is very important
00:19:59.462 --> 00:20:04.383
they need to know that they messed up they need to know that yeah there's consequence
00:20:04.383 --> 00:20:08.935
to pay and it's normal like they messed up right it needs to be clear
00:20:10.218 --> 00:20:14.913
I mean if it's serious I guess you'd look to potentially start looking at switching
00:20:14.913 --> 00:20:16.303
manufacturers after that,
00:20:16.823 --> 00:20:20.709
maybe there's no way back but if it's a mistake then,
00:20:21.156 --> 00:20:25.123
you know keeping good lines of communication open and preventing this from happening
00:20:25.123 --> 00:20:30.423
again maybe that's the better option i guess it depends on the on the situation
00:20:30.423 --> 00:20:34.415
right i mean if if we've got a like a smaller importer,
00:20:35.071 --> 00:20:38.683
realistically they're not going to have a full-time quality engineer in their
00:20:38.683 --> 00:20:43.523
suppliers factory right so how are they going to control those potential substitutions,
00:20:44.183 --> 00:20:46.023
especially if there's been an issue in the past.
00:20:47.423 --> 00:20:54.391
Well, hopefully they have a backup manufacturer, and depending on how to talk
00:20:54.391 --> 00:20:59.057
with the supplier that messed up that way goes,
00:21:03.181 --> 00:21:07.951
they might decide to go with the backup supplier. And if the backup supplier
00:21:07.951 --> 00:21:09.535
does well, well, that's it.
00:21:09.843 --> 00:21:13.419
The initial supplier is forgotten about.
00:21:14.621 --> 00:21:20.151
That makes a lot of sense. Now, there are cases where this is not possible,
00:21:20.151 --> 00:21:24.511
right? Maybe they buy it, but it's not even their product.
00:21:24.679 --> 00:21:29.347
It's an ODM product that they can only buy from this one factory.
00:21:30.195 --> 00:21:36.488
Well, in that case, right, they see you as maybe just a distributor of their products.
00:21:37.069 --> 00:21:38.963
Not so good. Not so good, right?
00:21:40.273 --> 00:21:46.466
Not many options for you. So that's one of the risks of relying on an ODM supplier.
00:21:48.039 --> 00:21:51.576
You can get to market much faster with much less investment.
00:21:52.943 --> 00:21:58.540
Product is basically already there, ready to sell, but you don't have a lot of control.
00:22:00.394 --> 00:22:04.712
That's a whole other podcast episode, Renaud, right there. Maybe we'll cover that in the future.
00:22:05.947 --> 00:22:10.987
Yeah, yeah, yeah. Different control depending on the kind of supplier, that's for sure.
00:22:11.177 --> 00:22:17.917
Yeah, yeah. Good. Okay, so I think we've pretty much expanded on these kind
00:22:17.917 --> 00:22:19.736
of unauthorized substitutions.
00:22:20.304 --> 00:22:23.521
I guess we're not what we're not saying is like every single,
00:22:24.617 --> 00:22:29.197
change or alternative is is a problem sometimes maybe it's not a problem if
00:22:29.197 --> 00:22:32.349
you're actually discussing this actively with your manufacturer and,
00:22:32.889 --> 00:22:38.327
and you know the components or materials are actually tested and validated and
00:22:38.327 --> 00:22:43.657
and eventually approved by yourself but it's when these decisions are happening without,
00:22:44.217 --> 00:22:50.177
you even knowing perhaps right and so renault's been through the potential drawbacks and and,
00:22:50.957 --> 00:22:55.307
problems that you're gonna get if this happens but also we've talked about some
00:22:55.307 --> 00:23:00.229
of the ways to prevent it and to identify if it's happening so thanks renault.
00:23:01.063 --> 00:23:01.952
