Just perusing Ebay Shutl terms and conditions and amongst the gems are

no compensation for

Electrical or electronic items (Monitors, mini fridges, lamps with glass or ceramics, tablets greater than 12 inches, printers containing ink or toner)


Or amongst prohibited items

"Magnetised material with a magnetic field strength of 0.159A/m or more at a distance of 2.1m from the outside of the package."


Additionally
If after acceptance a carrier discovers that the parcel contains prohibited goods it may dispose the parcel at it's own discretion. Shutl accepts no responsibility for this.

Yet will still accept one hard earned for enhanced compensation.

Hmm further research found this


Of note the following
"

And if you take out their insurance, you could be worse off than if you refuse.

In fact, many consumers are putting redress further out of reach by taking out these restrictive insurance policies.

myHermes will cover you up to £250 if you buy their insurance.

But if you don’t, they’ll pay whichever is the lower: £25, or the cost of replacing or repairing your item. 

They have to: that’s the law. A parcel delivery company has a legal duty to deliver your product safely and they should compensate you for any loss"

Hmmm Any loss. ...

TBC..

Its standard for anything going by air, not supposed to ship high power magnets, i spoke to a magnet specialist at Fane about this and they told me it should be ok for smaller drivers, but big motor systems can be over the limit and have to go sea Freight.  

Insurance is normally a rip off from these company's, 5% at parcel2go is just crazy, far far far less than 1 in 20 parcels gets lost or damaged so i just risk it without as ill be better off in the long run...

Having shipped Jerichos by air, that sounds like bobbins.

Narr its not,  high strength magnets are classed as hazardous goods and some drivers can measure higher than the limit (or thats what ive been told, i haven't personally measured any).  You probably just sent them, didnt tick the hazardous goods box and they got through fine, i very much doubt the airline measure each parcel, but it might possibly of been over the limit.  I tried to send some speakers via Transglobal Express once and they queried it, sent it over to there hazardous / dangerous goods person and they said it couldn't go air freight unless i paid too have the parcel measured to prove it was under the limit, had to go sea freight.  I do send the same speakers with the same drivers by air all the time though, its just i got pulled up on that one.  


  • Flux measurements of all packages containing magnets must measure less than 0.00525 gauss 15’ from the package. If flux measurements are less than 0.002 gauss when measured 7’ from the package, the package is not considered to contain magnetic material, and hence is not classified as Dangerous Goods. However, unless the package is extremely secure and there is no chance that the contents will shift or that shielding will be damaged in transit, it is safer to proceed as though the package falls under the DGR.

Thomann have told me they won't ship 18" or larger drivers to Australia anymore. They did a few years back but as of a year or so ago they said air freight companies won't let them.

Surely any decent air freight planes have magnetic shielded holds for this kind of stuff?

They were sent by a dedicated freight forwarder with all appropriate HS codes assigned to the shipments.

Were you shipping into or out of the UK? If importing from the US one would presume they have their own legislation in this area which may not match ours. Just a guess.

Having used many over the years freight forwarders are far from perfect. If you don't self declare it, they generally don't care. Put in box, move box, job done. After stamping all the crates with heat treated timber markings :)

Commodity code wont declare that it has high strength magnets in it, its just a code for what band of duty is applied AFAIK,  if you didnt tell them then they probably didnt know.  I think most company's will just ship it if you dont tell them its hazardous, ive sent speakers air freight many times and only been pulled up on it that one time.

We had some big magnets made in Spain for our motors, there was no option for flight only road, the magnet manufacturer said they can only ship by road and sea because of the problems with shipping them by air, I think they know what they are on about as they make and ship hundreds of thousands every year.

magnetic field falls with distance^3. If you are measuring several inches away it implies an up-close field thousands of times stronger. well-designed drivers shouldn't have a lot of stray field anyway.
