HS 293335 3-Quinuclidinol
Quick Answer: HS code 293335 specifically covers 3-Quinuclidinol, a heterocyclic compound containing an un-fused pyridine ring. This chemical is primarily used as an intermediate in the synthesis of pharmaceuticals and other fine chemicals. Importers and exporters should note the varying duty rates across major jurisdictions. In the UK and EU, the Most Favoured Nation (MFN) duty rate is 0.00% ad valorem, indicating duty-free entry for goods from most countries. Conversely, the United States applies an MFN duty rate of 5.8% ad valorem. However, significant preferential duty treatment is available for eligible imports from numerous countries under various Free Trade Agreements and preference programs (e.g., A+, AU, BH, CL, CO, etc.), often resulting in a 0.00% duty rate. For non-MFN rates, the US applies a compound duty of 15.4¢/kg + 39.5%. Accurate classification is crucial to leverage these preferential rates where applicable.

How to Classify This HS Code?
What products does HS 293335 cover?
This subheading covers 3-Quinuclidinol, a specific heterocyclic compound with a nitrogen hetero-atom, as defined by the World Customs Organization's Harmonized System Nomenclature and further detailed in the U.S. International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the European Union's TARIC database. 3-Quinuclidinol is a chemical compound with the molecular formula C7H13NO, characterized by a quinuclidine ring structure with a hydroxyl group at the 3-position. It is a key intermediate in the synthesis of various pharmaceuticals and other fine chemicals, and its classification here is precise, covering only the pure compound.
What falls outside HS 293335?
The following products are excluded from HS 293335: derivatives of 3-Quinuclidinol, such as its esters or ethers, which would typically be classified under other subheadings within Heading 2933 or Chapter 29 depending on their specific chemical structure and functional groups. For instance, if 3-Quinuclidinol is incorporated into a pharmaceutical preparation or a mixture, it would generally be classified under Chapter 30 or other relevant chapters, respectively, rather than as the pure chemical compound. Similarly, other quinuclidine derivatives not specifically identified as 3-Quinuclidinol are also excluded.
What are common classification mistakes for HS 293335?
A common error is misclassifying derivatives or mixtures containing 3-Quinuclidinol directly under HS 293335, rather than classifying the pure compound itself. Importers sometimes overlook General Interpretative Rule (GRI) 1, which dictates that classification is determined according to the terms of the headings and any relative section or chapter notes. For example, a pharmaceutical product where 3-Quinuclidinol is an active ingredient should be classified under Chapter 30, not as the raw chemical. Another mistake is confusing 3-Quinuclidinol with other isomers or structurally similar but distinct quinuclidine compounds, which belong to different subheadings.
How should importers classify products under HS 293335?
The correct procedure for classifying products under HS 293335 involves first verifying that the product is indeed pure 3-Quinuclidinol, matching its chemical name, structure, and CAS number (if available) to the official descriptions in the WCO HS Explanatory Notes and national tariffs like the USITC HTS or EU TARIC. Importers and customs brokers should obtain a Certificate of Analysis (CoA) or other technical specifications from the manufacturer to confirm the chemical identity and purity. If the product is a mixture or a derivative, it must be classified elsewhere, applying GRI 1 and subsequent rules as necessary to determine the correct heading and subheading based on its essential character or specific chemical structure.

FAQ
What are the standard Most Favored Nation (MFN) import duty rates for 3-Quinuclidinol (HS 2933.35) in major markets?
The MFN duty rates for 3-Quinuclidinol (HS 2933.35) vary by importing country. For example, the United States generally applies a 'Free' duty rate (0.00% ad valorem) under the Harmonized Tariff Schedule of the United States (HTSUS). The European Union's TARIC database also indicates a 0.00% ad valorem MFN duty rate. However, some countries may apply higher rates, such as a 5.8% ad valorem rate or complex rates like '15.4¢/kg + 39.5%' in specific jurisdictions. Importers should always verify the exact MFN duty rate with the customs authority of the importing country, referencing the latest tariff schedules such as the USITC HTSUS, EU TARIC, or the UK Trade Tariff.
Are there any preferential duty rates available for 3-Quinuclidinol (HS 2933.35) under free trade agreements or special programs?
Yes, preferential duty rates, often 'Free' (0.00% ad valorem), are frequently available for 3-Quinuclidinol (HS 2933.35) when imported from countries that have Free Trade Agreements (FTAs) or participate in special preference programs with the importing nation. For instance, the United States offers 'Free' duty rates under various agreements and programs, including but not limited to those with Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), and Singapore (SG). To claim preferential treatment, importers must ensure the goods meet the Rules of Origin criteria specified in the respective agreement and provide the necessary documentation, such as a Certificate of Origin. Customs brokers can assist in determining eligibility and preparing documentation.
What are the key classification criteria for 3-Quinuclidinol under HS 2933.35?
3-Quinuclidinol is classified under HS subheading 2933.35 because it is a heterocyclic compound containing only nitrogen hetero-atom(s), specifically a pyridine ring system, and is not otherwise specified in a more specific subheading within Chapter 29. The '35' in 2933.35 denotes 'Other compounds containing an unfused pyridine ring (whether or not hydrogenated) in the structure'. The World Customs Organization (WCO) Explanatory Notes for Chapter 29 provide guidance on the classification of organic chemicals, emphasizing the chemical structure and functional groups. Importers should ensure that the chemical name, CAS number (e.g., 1619-77-8 for 3-Quinuclidinol), and structural formula on product documentation precisely match the description for this subheading to avoid misclassification.
What specific documentation is required for importing 3-Quinuclidinol (HS 2933.35)?
Standard import documentation for 3-Quinuclidinol (HS 2933.35) typically includes a commercial invoice, packing list, bill of lading or air waybill, and a certificate of analysis (CoA) to confirm the chemical identity and purity. If claiming preferential duty rates under a Free Trade Agreement, a valid Certificate of Origin (e.g., USMCA Certificate of Origin, EUR.1 movement certificate) is mandatory. Depending on the importing country's regulations and the end-use of the chemical, additional permits or licenses from agencies such as the Environmental Protection Agency (EPA) or the Food and Drug Administration (FDA) in the US, or REACH compliance documentation in the EU, may be required. Importers should consult with their customs broker and the relevant regulatory bodies prior to shipment.
