Slip each book in a waterproof bag first. Secure the book in bubble wrap. If you are shipping multiple books, you may be able to package them together. Make sure the wrapping is tight so the book stays secure. The extra padding can prevent damage during handling. Consult with the company to find out what box sizes they allow. Make your boxes as small and flat as possible in order to save space and money. FedEx, for example, has a 10kg box for shipments up to 22 lbs. and a 25kg box for shipments up to 56 lbs. Seal the box with packing tape. Most companies will provide shipping material. If you bring your own, make sure the box or envelope is sturdy. Look over the package to make sure it looks secure and ready to go on its journey. Place it on a scale. Most post offices and shipping companies will do this for you and enter the weight into their system. An improperly-weighed box can incur charges that you or the recipient will have to pay later.  Splitting up heavier packages may save you on shipping expenses. Calculate how much it would cost you to send two packages instead of one heavy one. For an M-bag, for instance, the bag shouldn’t weigh more than 66 lbs (30 kg), including the sack. No matter how you ship the books, they need to be labeled. Shipping labels can be found online and printed. Many post offices also have them, and shipping companies will often put them on for you. Fill out one with your name and address in the upper left corner. Mark the center of the label with the recipient’s name, address, city, and country. Write clearly and in capital letters. When shipping via M-bag, you’ll need to fill out another address label to place on the bag. All international shipping has to be documented. Post offices stock these forms and most shipping companies will complete the documentation for you. In the US, for example, you’ll probably need the #2976 form. In the UK, this may be the CN22 form. Fill out the form as accurately as possible. You will need to state what you are sending and possibly other details, like what the books are made of.  These forms can be found online and filled out at home. Post offices and shipping companies also stock them. The post office or your local government can answer any questions you have. Sometimes, delivery costs more than expected. A country may charge a tax for the package, which can be a surprise to the person receiving it. Have the shipping company calculate the expense for you. It’s up to you to work with the package recipient to decide how to split extra charges.

Summary:
Wrap the book securely. Select your box or envelope size. Weigh the package. Label the box with the shipping and return address. Complete the customs form. Decide who pays import duties.
