Customs when purchasing from other countries

I have shipped many items to Thailand all by post from the UK, and todate have not lost anything, and generally DO NOT pay duties or VAT

On the declaration attached to the item, I would suggest you keep the value low and vague

If you use DHL / TNT/ FEDEX would will ihave additional cost

Courier company are okay for document deivered quickly if thats what you need

If you can wait 10 / 14 days regular post

On the declaration write 'SAMPLES ONLY, NO COMMERCIAL VALUE'. Never fails
