It is seemingly becoming more important/necessary to include the HTS (Harmonized Tariff Schedule) codes for shipping collectibles as of recent.
Would be nice to have a handy list for this considering the all of the items we ship to each other
A good lookup tool/website is:

Feel free to post which codes you use/have worked for you which will hopefully make packages get through customs/inspections quicker
