The Harmonized Commodity Description and Coding System, also known as the Harmonized System (HS) of tariff nomenclature is an internationally standardized system of names and numbers to classify traded products.
For import/export declarations in Hong Kong, commodity code in terms of the full 8-digit Hong Kong Harmonized System (HKHS) code has to be used for classifying the goods.

Today we list Kingtronics common products HS Code as below, hope this information can help you with your declaration process

For more detailed products information please check : http://www.kingtronics.com/

Hertz (Hz)
The basic unit of measurement of frequency. It is a measurement used to denote one complete occurrence of an event in one second.
The frequency of a crystal is measured in megahertz (MHz) or kilohertz (kHz). In Kingtronics we usually usd KHz.

Frequency 
Measured in Hertz (Hz), it is a periodic repetition of an event within a unit of time. 
In an electrical circuit, it is the number of times a resonator plate oscillates or vibrates in one second. The most common herts for Kingtroncis QKT is 32.768KHz

Frequency Tolerance
Often called Calibration Accuracy, it is the amount of frequency deviation from the specified nominal frequency at room temperature (25°C). 
This term is expressed as a minimum and maximum percent (%) or parts per million (ppm). Kingtronics can provide -20℃~+70℃, -40℃~+85℃, -10℃~+60℃

Load Capacitance
A capacitance, specified in picofarads (pF), presented to the crystal. 
The parallel load resonant frequency (FL) is a function of the load capacitance.

Quartz is used in the making of sandpaper, optics, glass, liquid filters, circuit boards, computer components, cement, mortar, and jewelry. Quartz crystals are also piezoelectric meaning when an electrical current passes through them they vibrate a small amount. Time can be measured from the vibrations of the quartz crystals so quartz crystals are often used in clocks.

Quartz crystals may either operate in a fundamental mode or in an overtone mode. Below frequencies of around 25 MHz crystals are normally designed to operate in their fundamental mode, whereas above this they will normally be designed for overtone operation, although with manufacturing techniques improving higher frequency crystals are becoming available. The mode is therefore an important element of the crystal specification.
