N007562 · 2007-03-01 — The tariff classification of pulse transformers (trigger coil) from Malaysia
The merchandise subject to this ruling is pulse transformers, also known as trigger coil transformers. Your letter states that PerkinElmer Optoelectronics designs and manufactures pulse (trigger coil) transformers for a wide range of specifications based on the various arc lamp applications. They are marketed as “trigger coils” because the process that effects the initial ionization within a flashlamp/arc lamp is known as “triggering”. Triggering creates a voltage gradient in the gas of sufficient magnitude to cause ionization of the lamps. You requested the classification of 5 pulse (trigger…
N007099 · 2007-02-27 — The tariff classification of a series injection triggering (Type A) transformer and external triggering (Type B) transformer from Malaysia
Each ruling request may contain a maximum of 5 items. Therefore, this ruling will determine the classification of 5 of the 53 transformers that you have requested a tariff classification ruling on. The merchandise subject to this ruling is injection triggering (Type A) transformers and external triggering (Type B) transformers. These transformers are trigger coil pulse transformers for application in arc lamp applications. They are marketed as “trigger coils” because the process that effects the initial ionization within a flashlamp/arc lamp is known as “triggering”. Triggering creates a…
g86834 · 2001-03-06 — The tariff classification of Voltage Regulators from New Zealand
The merchandise is described in your letter as Voltage Regulators. The Voltage Regulators are for use on electrical power systems. They incorporate power rectifiers and electronic controls combined with a power transformer in order to maintain voltage levels in power systems. They are static converters since they do not rely on rotating equipment. The power transformers range from 50 kVA to 6000 kVA. These transformer products are custom designed and manufactured to meet the specific requirements of individual customers, who typically will be large industrial companies and local electrical…
