There are three different labels that I am aware of:
1) The infamous 1999 engine label
2) TPEM Label
3) EPA Certified Label
Item 1, everyone can do at their own risk. The risk has just been much greater in the last year, and extremely high if attempting this year. Yes, we can speculate on how many of these engines were actually made /forums/images/graemlins/wink.gif
Item 2, allows for 200 units and follow meticulous paperwork. Not sure when this ends. I suspect this is what you are talking about, but first I've heard you had to pay more for that label. /forums/images/graemlins/confused.gif Not sure how often the paperwork is checked. Rest assured if you couldn't produce it, it probably impacts your next shipment. /forums/images/graemlins/wink.gif
Item 3, from what I know, will allow unlimited importing of certified engines. Certification has to be granted to particular US dealers/importers. Cost a good chunk of change. It sounds like major dealers will be receiving these, this year. I don't believe a small importer would be able to tag along on one of these, ie pay more for a certified label, with out express permission from the certification holder, which is not the chinese. If you purhase direct from the certification holder, expect to pay a premium for that. Most likely the premium will drop as the quantity goes up. Not sure how often the certification has to be renewed? If this goes out multi-years expect to pay less of premium next year, as these large dealers recoup their cost.
The good news is that the more popular engines are getting certified, ie the 395 and 385. This will ensure a good stateside supply of parts, for years to come. I am also speculating that the number of engine choices will go down. I doubt it will be cost effective, at least in the near-term, to pay for additional certifications, for engines like the 380. The 380 owners, don't have to worry because almost all parts are common on the 385.
