This is the problem, they have a good excuse for not sending it, just have to say it was seized.
I’ve also been evaluating alibaba option, but not tried it as yet - main reason being fear of scammy sellers. I was hoping that Trade Assurance feature of Alibaba could be of help in this regard.

"Seized by customs" question could also be solved by getting the package sent via a trackable postal service. Track record should show where the package is at the moment.
For trade assurance scheme to work, you have to buy from a trade assurance program member of alibaba. I’ve sifted through all "trade assured" tadalafil suppliers a month ago, and come up with this short list:
Zhengzhou Debao Fine Chemical Co. ; $344-426/kg ; min order 10gr ; 600kg/mo production ; response time:>72h ; response rate:%35,2 ; 5 yrs gold member
Xian Xuhuang Bio-Tech Co. ; 1 yr gold member ; 1-1000$/gr ; min order 10 gr ; 50kg/mo production ; response time:>72h ; response rate:%66,3
Huaian Chenhui Chemical Co. ; 5 yrs gold member ; 1-100$/gr ; min order 10 gr ; 50kg/mo production ; response time:>72h ; response rate:%62,2
Shandong Sunrise Technology Co. ; 2 yrs gold member ; 1-1000$/gr ; min order 1 gr ; 1000kg/mo production ; response time:<24h ; response rate:%97,5
Below 3 are the same seller with multiple alibaba entries:
Xi’an Sgonek Biological Technology Co. ; 1 yr gold member ; 1-1000$/gr ; min order 5gr ; 1 kg/mo production ; response time:24-48h ; response rate:%90,9 (Beware: Amino Tadalafil)
Beware of various modifications of tadalafil, particularly the so called "intermediate" tadalafil. Intermediate is not even modified tadalafil. It is an intermediate raw material to synthesize the final product. It’s probably ineffective to consume as-is, and might possibly be poisonous.
Example:
On the other hand, amino tadalafil is OK as far as I know. Amino is a harmless minor modification to the original tadalafil just in order to alleviate some patent problems. I don’t know how potent it is though (guess it’s same as plain tadalafil).
Tadalafil (C22H19N3O4) CAS number: 171596-29-5
Amino Tadalafil (C21H18N4O4) CAS number: 385769-84-6
These are my supplier research results with no experience. Anyone sharing his actual experience (good or bad) will be appreciated.
