HS 281129 Other
Quick Answer: HS code 2811.29, "Other," encompasses a diverse range of inorganic oxygen compounds of non-metals not elsewhere specified in subheading 2811.2. This includes various non-metallic oxides and oxygen acids beyond sulfur dioxide, sulfur trioxide, and nitrogen oxides. Examples might include certain phosphorus oxides or silicon dioxide (other than fused silica). Importers and exporters should note the varying duty rates: the UK applies a 4.00% ad valorem duty on many lines, while the EU typically ranges from 4.60% to 5.50% ad valorem. The US, however, generally applies a "Free" duty rate for products classified under this subheading. Due to its "Other" nature, precise classification requires careful review of product specifications against national tariff schedules to avoid misclassification and potential penalties.

How to Classify This HS Code?
What products does HS 281129 cover?
This subheading covers inorganic oxygen compounds of non-metals, specifically "Other" non-metallic oxides not elsewhere specified or included in more specific subheadings under Heading 2811. This includes a diverse range of chemical compounds such as silicon dioxide (silica), sulfur dioxide, and various nitrogen oxides, provided they are not carbon dioxide (2811.21) or other specific oxides with their own dedicated subheadings. The WCO Harmonized System Explanatory Notes for Heading 2811 clarify that this covers oxides of non-metals, and the USITC Harmonized Tariff Schedule (HTSUS) and EU TARIC system align with this broad residual classification for non-metallic oxides not specifically enumerated.
What falls outside HS 281129?
The following products are excluded from HS 281129: carbon dioxide (CO2), which is specifically classified under 2811.21. Furthermore, certain non-metallic oxides that are chemically pure and have specific industrial uses might be classified elsewhere if they meet the purity requirements for other headings or chapters, or if they are incorporated into mixtures or preparations. For instance, certain silicon compounds used as abrasives or in specific electronic applications might fall under different chapters if they are not simply the raw chemical oxide. Ozone (O3) is also excluded as it is an allotrope of oxygen, not an oxide of a non-metal in the context of this heading.
What are common classification mistakes for HS 281129?
A common error is misclassifying specific non-metallic oxides that have their own dedicated subheadings, such as carbon dioxide (2811.21), into this "Other" category. Another frequent mistake involves classifying mixtures containing non-metallic oxides under 2811.29 when the mixture's essential character is imparted by another component, requiring classification under a different heading or chapter according to General Interpretative Rule (GRI) 3(b). Importers sometimes also incorrectly classify certain silicon compounds, like silicates or silicones, as simple silicon oxides, overlooking their more complex chemical structures and intended uses which would lead to classification in Chapter 29 or 38.
How should importers classify products under HS 281129?
The correct procedure for classifying products under HS 281129 involves first confirming that the product is an inorganic oxygen compound of a non-metal. Importers and customs brokers must then meticulously review the full list of subheadings under Heading 2811 to ensure the specific oxide is not explicitly covered elsewhere, such as carbon dioxide (2811.21). If no more specific subheading applies, and the product is indeed an "other" non-metallic oxide, then 2811.29 is appropriate. Always consult the WCO Explanatory Notes, the USITC HTSUS, or the EU TARIC system, and obtain a chemical analysis or safety data sheet (SDS) to verify the exact chemical composition and purity of the product to ensure accurate classification.

FAQ
What are the typical Most Favored Nation (MFN) import duty rates for products classified under HS 2811.29 ('Other' non-metallic inorganic oxygen compounds) in major trading blocs?
The MFN import duty rates for HS 2811.29 can vary significantly by importing country or bloc. For instance, the United States (USITC) generally applies a 'Free' duty rate for many items under this subheading. The European Union (EU TARIC) often applies a 4.00% ad valorem duty. The United Kingdom Global Tariff (UKGT) also typically applies a 4.00% ad valorem duty. Other countries may have rates such as 4.60% or 5.50% ad valorem. Importers should consult the specific tariff schedule of the destination country for the precise and legally binding MFN duty rate.
How do I correctly classify a product under HS 2811.29, especially given its 'Other' designation?
HS 2811.29 is a residual subheading for 'Other' non-metallic inorganic oxygen compounds, following more specific subheadings within 2811. This means a product should only be classified here if it is a non-metallic inorganic oxygen compound that does not fit into 2811.11 (Carbon dioxide), 2811.19 (Other inorganic acids), or 2811.21 (Silicon dioxide). Proper classification requires a detailed chemical analysis of the product to confirm it is an inorganic oxygen compound of a non-metal and to rule out classification in more specific headings or subheadings. Referencing the Explanatory Notes to Chapter 28 of the Harmonized System (WCO) is crucial for accurate interpretation.
Are there any common preferential duty programs or free trade agreements that offer reduced or zero duties for HS 2811.29?
Yes, products classified under HS 2811.29 may be eligible for preferential duty treatment under various Free Trade Agreements (FTAs) or Generalized System of Preferences (GSP) programs, provided they meet the specific Rules of Origin. For example, imports into the United States from FTA partners like Mexico (USMCA), Canada (USMCA), or certain GSP beneficiary countries could be duty-free. Similarly, the EU has numerous FTAs (e.g., with South Korea, Japan) and GSP schemes that may grant preferential rates, often 'Free'. Importers must ensure they have valid Certificates of Origin (e.g., EUR.1, Form A, or specific FTA certificates) and meet all origin requirements to claim preferential tariffs.
What specific documentation is typically required by customs authorities for imports under HS 2811.29?
For imports under HS 2811.29, standard customs documentation includes a commercial invoice, packing list, and bill of lading or air waybill. Due to the chemical nature of these products, customs authorities may also request a Safety Data Sheet (SDS) or Certificate of Analysis (CoA) to verify the product's composition and ensure compliance with chemical regulations. If claiming preferential duty rates under an FTA or GSP program, a valid Certificate of Origin is mandatory. Importers should also be prepared to provide import licenses or permits if the specific chemical is subject to national chemical control laws (e.g., REACH in the EU, TSCA in the US).
