We have a condo here on San Pedro and I brought a bicycle to Belize from home (estimated cost of $120.00). The customs officer made note of it on my passport as I did not claim it(I had planned on brining it home). It's got a broken part (which is an odd size and I can't get a replacement here). I decided to leave it here and bring down another part next year. Does anyone know what I will be charged by customs for not bringing it back?

As it is written in your passport there is a good chance they will. They will come up with a price and charge duty and taxes. You might be able to go to immigration office on the island and get it taken care of before you leave

You can buy a bike here for about the same amount.
You can't change your situation, but for others reading this post, I'd recommend not going to the bother of bringing in a bike unless it's something special (and you have spare parts).
Good luck with customs.

No expert but I'd think they can only charge you if you are leaving Belize for good so if you have a return ticket to show you are coming back to Belize and still have your condo and the bike and will be using it - no duty. If you don't have a return ticket they will probably try and charge you if you are coming back or not and then I'd pop along to Customs before you leave to explain and ask wjhat to do. Be polite, whatever. A rant will guarantee a problem. Customs Officials are more precious than Heads of State - the world over.

What did you pay to bring it here, as they could charge 35% on the value and the same on cost to bring the bike here. I was just charged 35% on a flag from England, but left off the postage cost.

If it was a used bike it isn't the cost its the value. I assume that it was brought down as it was your favorite bike for the past 5 years with great sentimental value. but real value of $50. Besides you are allowed to bring a few hundred dollars of stuff in with out duty. Real the customs declaration when you came into the country.

This has been really helpful, I'll post the outcome!

I believe you can only bring in $200 duty free if you are either a citizen or a permanent resident. Even then if you go back and forth like I do and you enter more than twice in one year then you can not claim that exemption. I just got tripped up on that last month.

Your best route is to explain you situation respectfully to customs in San Pedro before you leave and by the way that was your favorite used bike like was suggested. Next time buy a bike here, I only bring in things that I can't get easily here. Less hassle and the locals have to make a living also.

Well we stopped at customs yesterday and ended up paying 37.5% I think it should have been 34.5%, but ah well that's the way it is. I'll have my bike fixed for next year, it has a great seat and takes the potholes really well.

In retrospect, maybe you should have just brought the bike's seat down with you? The local bike's are relatively cheap, easy to fix and parts can be found in many stores. Customs is always a crap shoot, I just smile and go along with them most of time. It is not worth getting upset about especially on a relatively small issue.
