HOUSTON (NBC News) -

How safe are the toys your child is getting for Christmas?

While action figures, toy trucks and princess crowns often make a child's Christmas list, officials with U.S. Customs and Border Protection (CBP) have a warning for parents.

“Just take a little bit of time before you open up the wallet and bring out the credit card or the cash, take a look at the product," said Roland Suliveras with CBP.

Be alert for easy access to dangerous materials.

"For a toddler that would be playing with this, they'd have direct access to these batteries, which would cause bodily harm," said Suliveras.

Parents should also keep an eye on toys that contain high levels of lead. Experts say the paint on some toys actually contains lead.

Many of the products arrive in the United States through Miami International Airport, and then make their way to other parts of the country.

“This year we actually ranked in the top five for seizures in IPRs (Intellectual Property Rights)," said Suliveras.

High quantities of counterfeit smartphones and pirated movies also make their way to South Florida during the holiday season.

"You're spending a lot of good money on some of these products, and they are actually fake," said Suliveras.

So how can you know what you should or shouldn’t buy?

One option is the drop test.

"Depending upon what falls off this toy, or how it actually breaks, and then we'll look at it to find out if it's actually dangerous for a child," said Suliveras.

The agency also encourages consumers to do research online before purchasing the products.
