HS 271129 Other

Quick Answer: HS code 2711.29, "Other," encompasses various gaseous hydrocarbons not falling under more specific subheadings within 2711.21 (Natural gas, liquefied) or 2711.22 (Propane, liquefied). This typically includes liquefied butanes, butene, and other petroleum gases, provided they are in a gaseous state and not otherwise specified. For importers and exporters, the duty rates across major jurisdictions are consistently 0.00% ad valorem in the UK and EU, and "Free" in the US, indicating no customs duties are levied on these products. The primary trade consideration for these goods often revolves around safety regulations, transportation logistics, and environmental compliance rather than tariff barriers, given their hazardous nature and specific handling requirements.

How to Classify This HS Code?

What products does HS 271129 cover?

This subheading covers petroleum gases and other gaseous hydrocarbons that are in a gaseous state and not liquefied, falling under Heading 2711. Specifically, it encompasses those gaseous hydrocarbons not elsewhere specified or included in subheadings 2711.21 (natural gas) or 2711.22 (propane). This includes various unliquefied hydrocarbon gases such as butanes, ethylene, propylene, butylene, and butadiene, provided they are not presented in a liquefied form. The WCO Harmonized System Explanatory Notes for Chapter 27 clarify that this subheading serves as a residual category for gaseous hydrocarbons not meeting the criteria for the more specific subheadings within 2711.2.

What falls outside HS 271129?

The following products are excluded from HS 271129: liquefied petroleum gases (LPG), which are classified under HS 2711.1X, such as liquefied natural gas (2711.11), liquefied propane (2711.12), and liquefied butanes (2711.13). Additionally, natural gas, even if unliquefied, is specifically classified under HS 2711.21. Propane, when unliquefied, is classified under HS 2711.22. Chemical products that are pure, separate organic compounds, even if gaseous hydrocarbons, are generally classified in Chapter 29, for example, pure methane (2901.10) or pure ethylene (2901.21), due to their specific chemical identity and purity levels.

What are common classification mistakes for HS 271129?

A common error is misclassifying liquefied petroleum gases (LPG) as unliquefied under 2711.29, or vice versa. Importers often overlook the critical distinction between the physical states (gaseous vs. liquefied) when classifying, which is a primary differentiator within Heading 2711. Another frequent mistake involves classifying specific unliquefied gases like natural gas (2711.21) or propane (2711.22) under the residual "other" subheading 2711.29, violating General Interpretative Rule (GRI) 6 which prioritizes subheadings at the same level. Furthermore, highly purified, separate organic gaseous compounds intended for chemical synthesis are sometimes incorrectly placed here instead of Chapter 29, overlooking GRI 1 and the specific provisions of Chapter 29.

How should importers classify products under HS 271129?

The correct procedure for classifying products under HS 271129 involves first confirming that the product is a petroleum gas or other gaseous hydrocarbon. Second, it is crucial to verify that the product is in a *gaseous* (unliquefied) state at standard temperature and pressure, distinguishing it from liquefied forms in 2711.1X. Third, importers must systematically rule out more specific subheadings within 2711.2, ensuring it is not natural gas (2711.21) or propane (2711.22). Finally, confirm it is not a pure, separate organic compound of Chapter 29. Customs brokers should request technical specifications, including vapor pressure and composition, to accurately determine the physical state and specific identity of the gaseous hydrocarbon, ensuring compliance with WCO Explanatory Notes and national tariff schedules like the USITC HTSUS or EU TARIC.

FAQ

What is the import duty rate for goods classified under HS 2711.29 in major markets?

For HS 2711.29, which covers 'Petroleum gases and other gaseous hydrocarbons: In gaseous state: Other', the Most Favored Nation (MFN) duty rates are generally 0.00% ad valorem in many key economies. For instance, the United States (according to the USITC Harmonized Tariff Schedule) applies a 'Free' rate for general imports. Similarly, the European Union's TARIC database and the UK Trade Tariff also list a 0.00% ad valorem duty rate for this subheading. Importers should always verify the specific duty rate applicable to their country of import via official tariff databases.

What are the key classification criteria for products under HS 2711.29?

HS 2711.29 specifically covers petroleum gases and other gaseous hydrocarbons that are in a gaseous state and are not otherwise specified in subheadings 2711.21 (Natural gas) or 2711.22 (Propane) or 2711.23 (Butanes). The primary criterion for classification here is the physical state (gaseous) and the chemical composition (petroleum gases or other gaseous hydrocarbons), excluding those explicitly covered by more specific subheadings within 2711.2. This 'Other' category typically includes mixtures of hydrocarbons not predominantly propane, butane, or natural gas, or single gaseous hydrocarbons not specifically named, provided they are derived from petroleum or are other gaseous hydrocarbons.

Are there any preferential duty rates available for HS 2711.29 under common trade agreements?

Given that the MFN duty rate for HS 2711.29 is already 0.00% or 'Free' in many major importing countries, there is typically no further reduction in duty available under preferential trade agreements such as the USMCA (United States-Mexico-Canada Agreement), EU Free Trade Agreements, or the UK's various trade agreements. The duty rate cannot go below zero. However, importers should still ensure compliance with rules of origin requirements under these agreements, as this can be crucial for other aspects of trade facilitation or statistical reporting, even if the duty impact is nil.

What specific documentation is required for importing goods under HS 2711.29?

While the duty rate for HS 2711.29 is often free, standard import documentation is still required. This typically includes a commercial invoice, bill of lading or air waybill, packing list, and potentially a certificate of origin (even if not for duty preference, it may be required for statistical or trade policy purposes). For certain gaseous products, a Safety Data Sheet (SDS) may be necessary to comply with national health, safety, and environmental regulations. Importers should consult their customs broker and the specific import requirements of the destination country, as additional permits or licenses related to hazardous materials or energy products might apply, regardless of the tariff classification.
