Chapter GROUP 3B Chemical and Petroleum Equipment
| IL1110 | Equipment for the production of liquid fluorine, and specially designed components therefor | C |
| IL1129 | Vacuum pump systems, the following and specially designed components, controls and accessories therefor— | |
(a) Cryopump systems (ie systems in which the circulation of cooled or liquefied gas is used to achieve a vacuum, static or dynamic, by lowering the temperature of the environment) designed to operate at temperatures of less than −200°C (−328°F) measured at atmospherical pressure | C | |
(b) Vacuum pump systems capable of evacuating a chamber of volume greater than one litre to pressures below 19−8 torr (1.3 × 10−6 pascals) while the temperature ;in the chamber is maintained abover 800°C | C | |
| IL1131 | Pumps (except vacuum pumps) designed to move molten metals by electromagnetic forces | C |
| IL1142 | Reinforced tubing (including connectors and fittings for use with such tubing) incorporating coagulated dispersion grades of polytetrafluroethylene, cocopymers of tetrafluoroethylene and hexafluropropylene, or any of the flurocarbon materials specified in entry IL1754 sub-head (a)(2), and designed for operating (working) pressures of 210.9 kg/cm2 (3,000 psi) or greater, whether or not specially processed to make the flow surfaces electrically conductive | C |
| IL1145 | Containers, jacketed only, specially designed for the storage or transportation of liquid fluorine | C |
