Products made in china and sold online seem to be exempt from all of these requirements, there are so many hazardous electrical devices still sold on Amazon even today, as an example.
Cracking down on the really dangerous stuff would be good ... but
There is still hope, however - In the USA, they have been agressively working to level this playing field and the American people area also making their own little war against all the chinese products sold online, so just push foward with this project and don't try to do something dishonest like the chinese guys, it always burns you in the end.
I would hate that we reverted back to the bad old days pre-cheap Chinese goods. All those dirt cheap electronic modules including Arduino (clones!), sensor modules, relay boards, motor controllers, DC-DC convertors etc. ad infinitum have massively fuelled the 'maker' movement if not actaully created it. Without them we would be back to the position where you either made everything youself from scratch, or paid $50+ for the simplest module, assuming it was even available.
A significant part of that cost would be needed to cover certification and compliance given the resulting limited size of the market. $5 to $10 costs/item could easily multiply to $20 to $30 or more by the time distributer and retailer markups and sales tax/VAT are included.
Yes its totally unfair and it sucks that local manufacturers are put at such a massive competitive disadvantage to Chinese suppliers who have additional tax (typically no VAT) and shipping cost advantages. But the real problem is the excessive regulatory burden imposed on small businesses. Of course safety is important but the emission requirements in particular are, in my opinion, almost totally pointless.
Yes there were cases of equipment being sold which caused severe interference to radio reception so regulation is good. But for a great deal of equipment and electronic modules almost nobody cares. It hardly matters if a set of electronic scales is 'noisy' given they are typically ony used for a few minutes at a time, but they can be fantastically useful on odd occasions. When they cost < $10 they are an easy purchase but if you had to pay $50+ for a fully compliant approved variety you likely wouldn't bother.
Same applies to an awful lot of stuff. Ultimately, cracking down on enforcing the regulations probably won't help small to medium local manfacurers much anyway. If forced, the Chinese suppliers will find ways to get very low cost domestic certification testing. I believe EMI certification is much cheaper in China anyway, but for low cost and/or lower volume products I expect they would respond with very low cost certification facilities providing as much 'certification' as justified for the type of product and its value, whilst being sufficient to cover regulatory controls in most export markets.
At the same time it would be just robust enough to cover any legal challenge that might be expected. Eg. smartphones etc. would get top of the line testing and certification. An automatic pet feeder would get the 'ecomomy' certification given that any domestic competition is likely to come from relatively small competitors with limited funding for legal action to prove that the Chinese certification was not up to standard.
To summarise, regulation is good up to a point but as always it seems to get ever more onerous over time as large
bodies of regulators have to continue to justify their salaries by perpetually changing and 'improving' the regulations. Cost benefit analyses be damned!
