None of them claim any value or suchlike for instructions. A lot depends on what an item is declared "as" Lasers are brought in under two classifications, "Industrial machines" and sometimes "Office supplies" the safety and CE requirements for the classes vary by a HUGE amount.
When a manufacturer claims a value on something, even when they give it away for free it changes the value of the package split for customs in the EU.
If I exported say
- Rocket Launcher $1,000
- Rocket for launcher $1,000
- Instructions for rocket launcher $1,000
Then sold the package for $2,000 customs will charge the VAT based on $3,000 not the $2,000 paid as that is the declared value on the export ticket.
EU customs can be really complex and a bit hit and miss to be honest...
On the LSO paperwork, the problem could easily be that companies and businesses here require an LSO to be appointed, it's a requirement of HSE regulations, offering paperwork as LSO training that actually isn't could easily put commercial ventures in hot water if an HSE inspector visits and wants to see the papertrail. I have two appointed LSO's here on staff and have to keep the paperwork for 7 years after any of them leave and make it available to authorised persons (ie: government) at any time just for the asking.
Regulatory controls and paperwork here for working with the use of lasers for commercial purposes is a nightmare, even for private use Lloyds (our biggest insurer) require that special insurance is taken out as lasers are considered a "Significant fire risk" so folks putting them in their kitchen etc may well find it invalidates their home insurance and Property use class.
If you have a 6,000 sqft house and use 500 sqft for the laser etc then that's likely going to be fine, you have a 1,200 sqft flat and use 500 sqft for the laser you will likely need a change of use registered with the local council and have to pay business rates if used for pecuniary advantage (gain)
