Chapter 15 is the HS classification category for "Animal or vegetable fats and oils and their cleavage products; prepared edible fats; animal or vegetable waxes." This chapter covers fats and oils extracted from animal and vegetable raw materials and their processed products, including virgin and refined fats and oils, fatty acids, glycerol, etc. However, it excludes animal fats and oils that have only undergone preliminary processing (such as unrendered pig fat) and certain specific fats and oils (such as lanolin). Goods in this chapter are important raw materials for industries such as food, chemicals, and pharmaceuticals. Heading 1515 covers "Other fixed vegetable fats and oils (including jojoba oil) and their fractions, whether or not refined, but not chemically modified." This heading includes a variety of less common vegetable oils, such as castor oil, tung oil, sesame oil, mustard oil, etc. However, it does not include chemically modified fats and oils of heading 1516, edible fat preparations of heading 1517, or industrial fats and oils of heading 1518. Code 151530 is a 6-digit subheading. The first 2 digits "15" represent Chapter 15 (Animal or vegetable fats and oils and their cleavage products). The 3rd-4th digits "15" represent heading 1515 (Other fixed vegetable fats and oils and their fractions). The 5th-6th digits "30" represent subheading 151530, specifically "Castor oil and its fractions." This subheading is not further subdivided; whether or not refined, it is classified under this code. Note: Castor oil is not chemically modified; if it has been chemically modified (such as hydrogenation or interesterification), it is classified under other headings. Castor oil is a fixed vegetable oil extracted from castor seeds, not chemically modified, and meets the description of heading 1515. It is not rapeseed oil of heading 1514, other fixed vegetable oils of heading 1515, or chemically modified fats and oils of heading 1516. Therefore, classification under 151530 is the most appropriate.

Product Name: The specific name of the declared commodity should be filled in as "castor oil" or "refined castor oil," etc., avoiding colloquial names. Processing Method: Indicate whether refined, whether virgin, whether cold-pressed, etc., such as "virgin," "refined," "cold-pressed." Whether Chemically Modified: Declare whether chemically modified, such as hydrogenation, interesterification, etc., usually "not chemically modified." Use: Fill in the main use, such as "industrial use," "pharmaceutical use," "cosmetic use," etc. Composition and Content: Main components and content, such as ricinoleic acid content, moisture and impurities, etc. Packaging Specifications: Packaging method and specifications, such as "iron drum, 200 kg/drum." Brand or Manufacturer: Fill in the brand or manufacturer name; if no brand, fill in "none." Origin: Fill in the country or region of origin of the goods, such as "India." Product Name: Refined castor oil; Processing Method: Refined, not virgin; Whether Chemically Modified: Not chemically modified; Use: Industrial use (lubricant raw material); Composition and Content: Ricinoleic acid ≥85%, moisture ≤0.5%; Packaging Specifications: Iron drum, 200 kg/drum; Brand: None; Origin: India. Mistakenly classifying chemically modified castor oil (such as hydrogenated castor oil) under 151530, when it should actually be classified under 1516. Failure to distinguish between virgin and refined, but 151530 covers both, which does not affect classification but affects the filling of declaration elements. Declaring the use as "edible" but actually industrial grade may lead to customs questioning and affect classification.

Core criteria for classification: 1) Whether the commodity is a fixed vegetable oil; 2) Whether it is extracted from castor seeds; 3) Whether it has been chemically modified. If the first two conditions are met and it is not chemically modified, it is classified under 151530. If chemically modified (such as hydrogenation or interesterification), it is classified under 1516. If it is a castor oil fraction (such as castor oil fatty acids), it is classified under other subheadings of 1515 or 2915, etc. 151511 Virgin linseed oil: Linseed oil and castor oil have different sources; linseed oil is classified under 151511, while castor oil is classified under 151530. The key difference lies in the plant species. 151519 Other linseed oil: Also linseed oil, but not virgin, still classified under 1515, but under a different subheading. Castor oil has its own subheading 151530. 151550 Sesame oil: Sesame oil has its own subheading 151550, different from castor oil. There are obvious differences in source and use. 151590 Other fixed vegetable oils: This subheading is a residual category; if castor oil were not specifically listed, it would be classified here, but since 151530 exists, it is not classified here. 151620 Hydrogenated castor oil: Hydrogenated castor oil is chemically modified and is classified under 1516, not 1515. Is it extracted from castor seeds? Is it not chemically modified? Is it a fixed vegetable oil? Is it used for industrial, pharmaceutical, or cosmetic purposes? Is it confused with linseed oil, sesame oil, etc.?

What is the difference in HS codes between castor oil and hydrogenated castor oil? Castor oil (not chemically modified) is classified under 151530; hydrogenated castor oil has been chemically modified and is classified under 151620. When classifying, it is necessary to confirm whether it has undergone chemical treatment such as hydrogenation. If castor oil is used for cosmetics, is it still classified under 151530? Yes, as long as castor oil is not chemically modified, regardless of whether the use is industrial, pharmaceutical, or cosmetic, it is classified under 151530. However, if it is made into a finished cosmetic product, it is classified under Chapter 33. How can it be determined whether castor oil has been chemically modified? Chemical modification includes hydrogenation, interesterification, oxidation, etc. If it has only undergone physical treatments such as refining, bleaching, and deodorization, it is not considered chemical modification and is still classified under 151530. Are the HS codes for castor oil and castor oil fatty acids the same? No. Castor oil is classified under 151530; castor oil fatty acids are fractions and are usually classified under other subheadings of 1515 or 2915 (such as ricinoleic acid). It needs to be determined based on the specific composition and degree of processing. What test reports are required when declaring castor oil? Usually, a composition analysis report (such as ricinoleic acid content), moisture and impurities, acid value, saponification value, etc., as well as a declaration of whether it has been chemically modified, are required. Specific requirements are subject to customs. Does castor oil have an independent HS code? Yes, in the HS 2017 version, castor oil has an independent subheading 151530. However, some countries may use national subheadings, so local tariff schedules need to be consulted. What tariff applies to castor oil imported from India? Tariff rates vary by country and trade agreement. It is recommended to consult the Chinese customs tariff schedule or a customs broker, and confirm whether preferential rates such as those under the Asia-Pacific Trade Agreement apply. How is castor oil classified if it is mixed with other oils? If after mixing it is still mainly castor oil, it may still be classified under 151530; if after mixing it becomes a product listed under another heading, it is classified under the corresponding heading. It needs to be determined based on the mixing ratio and use.
