Even if your question is unclear, the answer will likely not depend on which exact item you are bringing.
Airport security may require that you break any seals if they for some reason want to inspect the item in greater detail. It does not matter if it is in your hand luggage or checked luggage. If you refuse to break the seal, they may not allow you to bring the item, but have you dispose of it.
Going through customs when entering the Phillipines, customs officers will also be entitled to break the seal if a more thorough inspection is required. Here, you can not expect to have the option to dispose of the item, since the customs officers will be interested in uncovering even the attempt to import illegal products, substances, whatever.
If you have to pay any duty when importing the item depends on the value of the product. If the IATA page on Phillipine customs regulations is up to date, you are allowed to freely bring 'one non-consumable item with a value of max. USD 200'.
