Cow Milk and Colostrum: Different Attributes and Classificationsforeign tradeDark Chocolate and White Chocolate: Differences Beyond Color

Corn and Sweet Corn: Differences in Edibility and Cultivation

Milk, as a daily - consumed dairy product, its classification is affected by the processing method. Milk that is not concentrated or sweetened is classified under item 0401, while milk that has been concentrated or sweetened is classified under item 0402. Colostrum, especially that collected within 24 hours after calving, is significantly different from milk. Its main components include 18 - 25% solids, 4 - 5% fat, and 10 - 15% protein. Therefore, according to the tariff regulations, colostrum should be classified under item 04049000.

Rubber and Silicone: Distinctions in Materials and Applications

There are many types of chocolates, but in tariff classification, the difference between dark chocolate and white chocolate is particularly obvious. Dark chocolate, due to its high cocoa solids content (70% - 99%) and low milk content (less than 12%), is classified under item 1806. White chocolate, which contains no cocoa and is composed only of sugar, cocoa butter, milk powder, and flavorings, is thus classified under item 17049000.

Corn vs. Sweet Corn: Differences in Consumption and Cultivation

Corn, as a major food crop in the world, has a relatively simple tariff classification and is classified under item 1005. However, sweet corn is different. It is sweet - tasting and is usually consumed as a vegetable. According to the tariff notes, sweet corn should not be classified under item 1005 but under Chapter 7. For example, frozen sweet corn should be classified under item 07104000.

Rubber vs. Silicone: Material and Application Differences

Rubber, as a widely used synthetic material, is classified in Chapter 40 of the tariff regulations. Silicone, although it has a similar name, is essentially different from rubber. Inorganic silicone and organic silicone are classified under item 28112210 and item 2931 respectively due to their different properties. Silicone rubber, also known as polysiloxane, is usually classified under item 39100000.

Cameras and Film Cameras: Comparison between Electrical and Optical

Cameras, which utilize electronic technology to convert images into electrical signals, fall under heading 8525. On the other hand, film cameras record images on film through photochemical reactions and do not involve electrical effects. Therefore, film cameras, as optical devices, are classified under headings 9006 "photographic cameras" and 9007 "cinematographic cameras."

Brass Instruments and Copper Instruments: Differences in Sound Quality and Materials

Brass instruments, such as cornets, trumpets, and saxophones, are not only made of brass. Their sound quality and shape make them classified under item 92051000. Copper instruments, although mainly made of brass, if they do not meet the sound quality requirements of brass instruments, should be classified under item 92059.

Wires and Cables: Differences in Structure and Application

Wires are conductive wires coated with an insulating layer and are classified under tariff numbers such as 85444219, 85444229, 85444919, 85444929. Cables, which are composed of multiple insulated conductive wire cores and have a more complex structure, are classified under tariff numbers such as 85444211, 85444221, 85444911, 85444921. Coaxial cables, as a special type of cable, are classified under item 85442000.
