S.C. Code Ann. Regs. 5-407 – Exemptions from Classification as Banned Hazardous Substances.

(a) The term “banned hazardous substances” as used in Section 23-39-20(p)(1)(a) of the act and 5-390 shall not apply to the following articles provided that these articles bear labeling giving adequate directions and warnings for safe use:
(1) Chemistry sets and other science education sets intended primarily for juveniles, and replacement components for such sets, when labeled in accordance with 5-406(a)(23).
(2) Common fireworks devices suitable for use by the public (such as toy paper caps, cone fountains, cylinder fountains, whistles without report, and sparklers, but not including fireworks devices that may be confused with candy or other food, such as “dragon eggs” and “crackerballs”, also known as “ball-type caps”), if such devices are:
1. (i) Designed to produce only visible effects by combustion; or are
2. (ii) Designed to produce audible effects, if the audible effect [is] produced by a charge of not more than 2 grains of pyrotechnic composition.
(3) [Reserved]
(4) Educational materials such as art materials, preserved biological specimens, laboratory chemicals, and other articles intended and used for educational purposes.
(5) Liquid fuels containing more than 4 percent, by weight, of methyl alcohol that are intended and used for operation of miniature engines for model airplanes, boats, cars, etc.
(6) Novelties consisting of a mixture of polyvinyl acetate, U. S. Certified Colors, and not more than 25 percent, by weight, of acetone, and intended for blowing plastic balloons.
(7) Games containing as the sole hazardous component, self-pressurized container of soap solution or similar foam-generating component has no other hazards other than being in a self-pressurized container.
(8) Model rocket propellant devices designed for use in lightweight, recoverable, and reflyable model rockets, provided such devices:
1. (i) Are designed to be ignited by electrical means.
2. (ii) Contain no more than 62.5 grams (2.2 ounces) of propellant material and produce less than 80 newton-seconds (17.92 pounds seconds) of total impulse with thrust duration not less than 0.050 second.
  (iii) Are constructed such that all the chemical ingredients are preloaded into a cylindrical paper or similarly constructed nonmetallic tube that will not fragment into sharp, hard pieces.
3. (iv) Are designed so that they will not burst under normal conditions of use, are incapable of spontaneous ignition, and do not contain any type of explosive or pyrotechnic warhead other than a small parachute or recovery-system activation charge.
(9) Separate delay train and/or recovery system activation devices intended for use with premanufactured model rocket engines wherein all of the chemical ingredients are preloaded so that user does not handle any chemical ingredient and are so designed that the main casing or container does not rupture during operation.
(10) Solid fuel pellets intended for use in miniature jet engines for propelling model jet airplanes, speed boats, racing cars, and similar models, providing such solid fuel pellets:
1. (i) Weigh not more than 11.5 grams each.
2. (ii) Are coated with a protective resinous film.
  (iii) Contain not more than 35 percent potassium dichromate.
3. (iv) Produce a maximum thrust of not more than 7 and 1/2 ounces when used as directed.
4. (v) Burn not longer than 12 seconds each when used as directed.
(11) Fuses intended for igniting fuel pellets exempt under subparagraph (10) of this paragraph.
(12) Kits intended for construction of model rockets and jet propelled model airplanes requiring the use of difluorodichloromethane as a propellant, provided the outer carton bears on the main panel in conspicuous type size the statement, “WARNING—Carefully read instructions and cautions before use”.
(13) Flammable wire materials intended for electro-mechanical actuation and release devices for model kits described in subparagraph (12) of this paragraph, provided each wire does not exceed 15 milligrams in weight.
