HS 282550 Copper oxides and hydroxides

What products does HS 282550 cover?

This subheading covers copper oxides and hydroxides, specifically di-copper oxide (cuprous oxide, Cu2O), copper(II) oxide (cupric oxide, CuO), and copper hydroxides (e.g., Cu(OH)2). These chemical compounds are distinguished by their specific chemical formulas and properties, as detailed in the Harmonized System Explanatory Notes for Heading 2825, published by the World Customs Organization (WCO). The scope encompasses these inorganic compounds in various forms, such as powders, granules, or pastes, provided they retain their chemical identity as copper oxides or hydroxides. Official definitions from the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system align with this WCO interpretation, ensuring consistent global classification.

What falls outside HS 282550?

The following products are excluded from HS 282550: copper carbonates, which are classified under HS 2836 (e.g., basic copper carbonate, malachite); copper sulphates, classified under HS 2833; and copper pigments, even if they contain copper oxides, if they are prepared as pigments and fall under Chapter 32. For instance, prepared pigments based on copper oxides, such as those used in paints or ceramic glazes, are typically classified under HS 3206. Additionally, copper compounds that are not oxides or hydroxides, such as copper chlorides (HS 2827) or copper nitrates (HS 2834), are also excluded, as their chemical structure places them in different subheadings within Chapter 28 or other chapters entirely.

What are common classification mistakes for HS 282550?

A common error is misclassifying prepared copper oxide-based pigments or mixtures containing copper oxides as pure copper oxides under HS 282550. Importers often overlook the distinction between a pure chemical compound and a formulated product. For example, a mixture of copper oxide with binders or dispersants, intended for use as an antifouling paint ingredient, would likely be classified under Chapter 32 as a prepared pigment or preparation, rather than under HS 282550. This mistake often arises from failing to apply General Interpretative Rule (GRI) 1, which dictates classification by the terms of the headings and section or chapter notes, and GRI 3(b) for mixtures, which prioritizes the component giving the mixture its essential character.

How should importers classify products under HS 282550?

The correct procedure for classifying products under HS 282550 involves a thorough review of the product's chemical composition and intended use. Importers and customs brokers should first verify that the product is indeed a copper oxide (Cu2O, CuO) or copper hydroxide (Cu(OH)2) and not a mixture, compound, or preparation of copper. Obtain a detailed Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer to confirm the exact chemical identity and purity. Consult the WCO Harmonized System Explanatory Notes for Heading 2825, along with the specific national tariff schedules (e.g., USITC HTS, EU TARIC, UK Trade Tariff), to ensure alignment with official interpretations. If the product is a mixture or preparation, consider GRI 3(b) to determine if the copper oxide or hydroxide imparts the essential character, or if it falls under a more specific heading elsewhere, particularly in Chapters 32 or 38.
