Yeah if you look at the bottom of each box it says"Confirms to the safety requirements of ASTM F963."
Here is the ASTM f963 requirements,(Srryz forz being so longz)
1.1 This specification relates to possible hazards that may not be recognized readily by the public and that may be encountered in the normal use for which a toy is intended or after reasonably foreseeable abuse. It does not purport to cover every conceivable hazard of a particular toy. This specification does not cover product performance or quality, except as related to safety. Except for the labeling requirements pointing out the functional hazards and age range for which the toy is intended, this specification has no requirements for those aspects of a toy that present an inherent and recognized hazard as part of the function of the toy. Such an example is a sharp point necessary for the function of a needle. The needle is an inherent hazard that is well understood by the purchaser of a toy sewing kit, and this hazard is communicated to the user as part of the normal educational process.
1.2 On the other hand, while a riding toy has inherent hazards associated with its use (for example, falling off onto the sidewalk), the possible hazards associated with its construction (sharp edges, exposed mechanisms, etc.) will be minimized by the application of this specification.
1.3 This specification covers requirements and contains test methods for toys intended for use by children under 14 years of age. Different age limits for various requirements will be found in this specification. These limits reflect the nature of the hazards and expected mental or physical ability, or both, of a child to cope with the hazards.
1.4 Articles not covered by this specification are as follows:
Bicycles
Tricycles
Sling shots and sharp-pointed darts
Playground equipment
Non-powder guns
Kites
Hobby and craft items in which the finished item is not
primarily of play value
Model kits in which the finished item is not primarily of
play value
Crayons, paints, chalks, and other similar art materials in
which the material itself or the finished item is not
primarily of play value, except that all art materials,
whether or not a component of a toy, must comply with
LHAMA, in accordance with 4.29.1-4.29.3.
Toy Chests
Sporting goods, camping goods, athletic equipment, mu-
sical instruments, and furniture; however, toys that are
their counterparts are covered. (It is recognized that
there is often a fine line between, for example, a musical
instrument or a sporting item and its toy counterpart.
The intention of the producer or distributor, as well as
normal use and reasonably foreseeable abuse, deter-
mines whether the item is a toy counterpart.)
Powered models of aircraft, rockets, boats, and land
vehicles; however, toys that are their counterparts are
