Because the remit of the Convention covers millions of species of plants and animals, and tens of thousands of these taxa are potentially of economic value, in practice this negative list approach effectively forces CITES signatories to expend limited resources on just a select few, leaving many species to be traded with neither constraint nor review.

Because of the orbital character, the potential for developing stereoisomeric products upon cycloaddition is limited, as described by the Woodward-Hoffmann rules.

Because this geometrical interpretation of multiplication was limited to three dimensions, there was no direct way of interpreting the product of four or more numbers, and Euclid avoided such products, although they are implied, e. g., in the proof of book IX, proposition 20.

Because an electron beam only penetrates to a limited depth before being absorbed, typically up to 5 cm for electron energies in the range 5 – 20 MeV, electron therapy is useful for treating skin lesions such as basal cell carcinomas.

Because subwoofers are generally limited to a bandwidth of no higher than 150 Hz, the switching speed for the amplifier does not have to be as high as for a full range amplifier, and simpler designs could be utilized.

Because SOFCs are made entirely of solid materials, they are not limited to the flat plane configuration of other types of fuel cells and are often designed as rolled tubes.

Because of their small size and limited projectile penetration compared to high-power rifle rounds, submachine guns are commonly favored by military, paramilitary and police forces for close-quarters engagements such as inside buildings, in urban areas or in trench complexes.

Because they fire pistol ammunition, they have limited long-range use, but in close combat can be used in fully automatic in a controllable manner due to the lighter recoil of the pistol ammunition.
