Chapter 21 is the 'Miscellaneous edible preparations' category in the HS classification system, covering a wide range including extracts and preparations of coffee, tea, and cocoa, yeast, baking powder, sauces and mixed condiments, soups and soup preparations, ice cream and other edible ice preparations, and food preparations not elsewhere specified. This chapter is characterized by goods that are mostly complex processed foods with mixed ingredients, usually not classified under Chapters 1-20 as primary agricultural products or simply processed goods. Chapter 21 is a common 'residual chapter' in food classification, and many compound condiments and convenience foods are classified under this chapter. Heading 2103 covers 'Sauces and preparations therefor; mixed condiments and mixed seasonings; mustard flour and meal and prepared mustard'. Specifically, it includes: soy sauce (2103.10), tomato ketchup and other tomato sauces (2103.20), mustard flour and meal and prepared mustard (2103.30), and other sauces and mixed condiments (2103.90). The core of this heading is the 'seasoning' function, i.e., products used to enhance food flavor and typically not consumed alone as a staple food. As the residual subheading of this heading, 2103.90 covers all sauces and mixed condiments not named in other subheadings. Code 210390 is a 6-digit HS code. The first 2 digits '21' represent Chapter 21 'Miscellaneous edible preparations', indicating that the goods belong to the miscellaneous category of food, rather than primary agricultural products or beverages. The 3rd-4th digits '03' represent heading 2103 'Sauces and preparations therefor; mixed condiments and mixed seasonings; mustard flour and meal and prepared mustard', clarifying that the core function of the goods is seasoning. The 5th-6th digits '90' represent the subheading 'Other', i.e., under this heading, in addition to the specifically named subheadings for soy sauce, tomato ketchup, mustard, etc., all other sauces and mixed condiments are classified under this subheading. Therefore, 210390 is the broadest residual code for sauce-type goods. This goods is classified under 210390 because it is a sauce but is neither soy sauce (2103.10), tomato ketchup (2103.20), nor prepared mustard (2103.30). At the same time, it is not a vegetable preparation of Chapter 20 (such as vegetables preserved in vinegar) or a coffee seasoning of Chapter 9. If the product is a single-ingredient spice (such as pepper powder), it may be classified under Chapter 9; if it is a mixed condiment used for seasoning, it is classified under 2103.90. Therefore, 210390 is the only correct classification for other sauces.

The core criteria for classification are the product's ingredients, processing technology, and use. 210390 applies to other sauces and mixed condiments, i.e., products used to enhance food flavor and typically not consumed alone. If the product is a single-ingredient spice (such as pure pepper powder), it should be classified under Chapter 9; if it is vegetables preserved in vinegar, it should be classified under Chapter 20; if it is soup or soup preparations, it should be classified under 2104. Therefore, when determining, it is necessary to confirm whether the product is a mixed condiment, whether it is used for seasoning, and whether it is a product not named in other subheadings of 2103. 210310 Soy Sauce: Soy sauce is a liquid condiment made by fermenting soybeans, wheat, etc., with specific production processes and ingredient standards. If the product is a soy sauce base but with other ingredients added to change the flavor, it may still be classified under 210310, but if it has lost the basic characteristics of soy sauce, it is classified under 210390. 210320 Tomato Ketchup and Other Tomato Sauces: Tomato ketchup uses tomato as the main raw material, usually with high tomato content.

If the product is a mixed sauce with mustard accounting for only a small portion, it is classified under 210390. 210410 Soups and Broths and Preparations Therefor: Soup preparations are usually concentrated preparations used to make soup, while sauces are used for seasoning. If the product is in sauce form and directly used for seasoning, it is classified under 210390; if it is powder or concentrated liquid used for making soup, it is classified under 210410. 091091 Mixed Spices: Mixed spices are made by mixing two or more spices without adding other seasoning ingredients. If salt, sugar, oil, etc. are added to the product, changing the nature of the spices, it is classified under 210390. Is the product used for seasoning rather than consumed alone? Is the product made by mixing two or more ingredients? Is the product not soy sauce, tomato ketchup, or prepared mustard? Is the product not classified under Chapter 9 or Chapter 20? Does the product have the physical characteristics of a sauce (such as sauce-like, paste-like)?
