Do I have to pay VAT or any other form of sales tax on products bought through optics-world.com?

We do not add any additional charges or taxes in the products price.
 

Normall, we declare the custom invoice as small value and "samples only" or "gifts". in this way. most of the country don't need pay tax. but we can't guarantee that. even some parcel need pay extra tax. we think that should be very very samll. becaue we declare the value for one items is less than USD50.00, in recently years, DHL/FEDEX also need delcare the parcel value no less than USD110.00. IF Lower than USD110.00. Should supply the payment proof. so Now,  we will dclare the parcel no less than USD110.00 to some countries (For exmaples. TO UK), maybe the buyer will pay a small amount tax in their side. 
 

Of course, if you have any special requirements, please inform us, normally, we can do that according to you requirements for declaring value in the custom invoice.

Possible additional costs to you may include:
- bank transfer charges (if choose T/T payment off line),
- Paypal money 'upload' charges,
- Any import duties that are levied at customs.
