Shipping Speakers overseas from Japan
Japan Post will not accept speakers. Why?
If you try to ship speakers overseas through Japan Post, you will find that they do not accept any kind of speakers nowadays. You may have already tried to send through post office and found out now that it is not possible to ship speakers overseas from Japan. Some speakers are magnet-shielded and while others are not. The magnet-shielded ones are not considered dangerous goods when transported by air. However, it is not possible for Japan Post to checkwhether each speake is magnet-shielded. That is why they will not accept any kind of speakers for international shipping whether they are magnet-shielded or not.
Some people misunderstand the reason but the reason why speakers are not accepted by Japan Post is because magnet affects the electric devices of the airplanes.
Therefore, they are considered as dangerous goods.
Can they be shipped as airfreight?
Magnet-shielded speakers can be accepted for air transport if some kind of proof stating that the model concerned is magnet-shielded. Normally, url of the product on the manufacturer’s website or catalogue would do. Most speakers which are designed to be used next to PC monitors or TV screens are magnet-shielded while the ones for audio use especially the ones from old days are not.
Most speakers can be shipped via ocean.
There should be no problem if transported by ocean, however, the minimum for ocean freight is one cubic meter. So, this will perhaps be an option only when one is sending some large vintage one or possibly together with other audio equipment such as an amplifier or there is no other option.
