We moved from the U.S. to Portugal last year. Sold everything except the bare essentials and only brought 8 suitcases with us. I checked through 2 dozen tubes of oil paint. On top of the plastic box I taped on a note to TSA–found the template online somewhere–maybe OutdoorPainter.com–about the tubes enclosed being artist colors made with vegetable material. Also included the MDS sheets I found online that verified the high flash point. No solvents allowed. I did the same for 2 sets of pastels, just in case. I packed two plein air pochade boxes, tripod, and umbrella in the same suitcase. No problems. If you are shipping, I don’t know any of that is necessary. Professional quality art materials are not easily sourced in Portugal so my only regret is that I did not bring MORE art supplies and less clothing!
