HS 281119 Other

What products does HS 281119 cover?

This subheading covers inorganic acids other than hydrogen fluoride (HS 281111) and hydrogen cyanide (HS 281112). Specifically, it encompasses a range of inorganic oxygen compounds of non-metals, as defined by the World Customs Organization (WCO) Harmonized System (HS) Nomenclature for Heading 2811. Examples include sulfur dioxide (SO2), sulfur trioxide (SO3), nitrogen oxides (e.g., N2O, NO, NO2), carbon dioxide (CO2), and silicon dioxide (SiO2) in its various forms, provided they meet the purity requirements for Chapter 28. The USITC Harmonized Tariff Schedule (HTS) and EU TARIC further elaborate on these inclusions, ensuring consistent global application for these fundamental chemical compounds.

What falls outside HS 281119?

The following products are excluded from HS 281119: hydrogen fluoride (classified under HS 281111) and hydrogen cyanide (classified under HS 281112), as these have their own specific subheadings. Furthermore, certain inorganic acids that are specifically provided for elsewhere in Chapter 28 or other chapters are also excluded. For instance, complex inorganic acids, such as heteropoly acids, or acids that are part of a mixture or preparation, may be classified under different headings depending on their composition and primary function. Similarly, silicon dioxide in a form specifically prepared as an abrasive or a filtering medium might be classified in Chapter 68 or 69, respectively, if its primary use dictates a different classification.

What are common classification mistakes for HS 281119?

A common error is misclassifying specific inorganic acids that have their own dedicated subheadings, such as hydrogen fluoride or hydrogen cyanide, into 281119, which is intended for "other" inorganic acids. Another frequent mistake involves classifying mixtures or preparations containing these acids, rather than the pure acids themselves, under 281119. General Interpretative Rule (GRI) 3(b) often applies here, requiring classification based on the component that gives the mixture its essential character. Importers sometimes also overlook the purity requirements for Chapter 28, attempting to classify technical-grade or impure forms of these acids that might be more appropriately classified elsewhere, potentially in Chapter 38 if they are preparations not elsewhere specified or included.

How should importers classify products under HS 281119?

The correct procedure for classifying products under HS 281119 involves a meticulous review of the product's chemical identity, purity, and form. Importers and customs brokers should first confirm that the product is indeed an inorganic acid and not hydrogen fluoride or hydrogen cyanide. Next, verify that it is not specifically provided for in another heading or subheading within Chapter 28 or elsewhere in the HS. Consult the WCO HS Explanatory Notes for Heading 2811, along with the specific definitions provided by the USITC HTS and EU TARIC. Obtain a Certificate of Analysis (CoA) or a Safety Data Sheet (SDS) to confirm the chemical composition and purity, ensuring it meets the criteria for Chapter 28. If the product is a mixture, apply GRI 3(b) to determine the essential character before assigning a classification.
