For my opinion the cone is dry material which is low risk on custom clearance might be no issue, if send directly to the Indigo studio.
But to ensure I propose to send the sample to TH UL same as previously shipment, then someone come to correct the sample with us at RDC TH.
If you required 100 pcs should send more sample may be around 150-200 pcs due will have some damaged while transportation.
