Customs Knowledge: Safety Inspection and Supervision Require

Acetic acid is not only a dangerous commodity but also a hazardous chemical. Acetic acid is a precursor chemical that needs to be exported to specific countries (regions) such as Myanmar, Laos, and Afghanistan with a "Dual Use Item and Technology Export License".

 

 

 

Glacial acetic acid, also known as glacial acetic acid, with the chemical formula CH3COOH, is an organic monobasic acid. Pure anhydrous glacial acetic acid is a colorless, hygroscopic solid with a freezing point of 16.6 ℃ (62 ℉). After solidification, it becomes a colorless crystal. Its aqueous solution is weakly acidic and highly corrosive, and steam has a irritating effect on the eyes and nose.

 

 

 

1、 The main uses of glacial acetic acid

 

 

 

Acetic acid can be divided into industrial and edible types according to its use. Industrial glacial acetic acid is one of the most important organic acids, mainly used in vinyl acetate, acetic anhydride, acetate fibers, acetate esters, and metal acetate. It is also used as a solvent and raw material in industries such as pesticides, pharmaceuticals, and dyes. It is widely used in the manufacturing of photographic drugs, textile printing and dyeing, and rubber industries.

 

 

 

Edible glacial acetic acid can be used as a sour and flavoring agent, and can be used to produce synthetic edible vinegar. Dilute glacial acetic acid with water to a concentration of 4%~5%, and add various seasoning agents to obtain edible vinegar. Its flavor is similar to brewing vinegar, and is commonly used in tomato sauce, mayonnaise, drunk rice sugar sauce, kimchi, cheese, sugar products, etc.

 

 

 

2、 HS Code Classification and Regulatory Requirements for Import and Export of Glacial Acetic Acid

 

 

 

According to the "Import and Export Tariff Comparison User Manual" (2021 edition), glacial acetic acid is mainly divided into food grade and other types.

 

 

 

1. Glacial acetic acid (food grade), classified under tax number 29152111, regulatory certificate code A/B/G, inspection and quarantine category MR/NS, with an export tax refund rate of 13%.

 

 

 

2. Acetic acid (other), classified as tax number 29152119, regulatory certificate code G. Industrial glacial acetic acid is included in this tax number, and the export tax refund rate is 13%.

 

 

 

3、 Classification of hazardous characteristics and overview of hazards of glacial acetic acid

 

 

 

Acetic acid is a Class 8+3 dangerous goods listed in the United Nations' Recommendations and Model Regulations on the Transport of Dangerous Goods, with a UN number of 2789, a flash point of 41 ℃, and a packaging category of Class II. It is also a hazardous chemical listed in the "Catalogue of Hazardous Chemicals" (2015 edition). （1） Health hazards
