HS 292700 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile) (CAS RN 15545-97-8)
Quick Answer: HS code 292700 specifically covers "2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile)," a chemical compound identified by CAS RN 15545-97-8. This substance is primarily used as a polymerization initiator in various industrial applications, particularly in the production of plastics and resins. Importers and exporters should note the significant variations in duty rates. The UK Trade Tariff generally applies a 0.00% ad valorem duty rate. In contrast, the EU TARIC system typically levies a 6.50% ad valorem duty. For the United States, the General duty rate is 5.8% ad valorem, though many preferential programs (e.g., A+, AU, CL, KR) offer a "Free" rate. However, certain specific classifications under 2927.00.00 may incur a compound rate, such as 15.4¢/kg + 40.5% ad valorem, highlighting the critical need for precise classification and origin determination to optimize customs duties.

How to Classify This HS Code?
What products does HS 292700 cover?
This subheading covers 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile), identified by CAS RN 15545-97-8. This specific chemical compound is an azo-nitrile, falling under Heading 2927 of the Harmonized System, which encompasses "Diazo-, azo- or azoxy-compounds." The WCO Harmonized System Nomenclature and official tariff schedules such as the USITC Harmonized Tariff Schedule (HTSUS) and the EU TARIC system precisely define this subheading to include only this distinct chemical, ensuring a narrow and unambiguous scope for classification within Chapter 29, which covers organic chemicals.
What falls outside HS 292700?
The following products are excluded from HS 292700: any other diazo-, azo-, or azoxy-compounds that are not specifically 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile). For instance, other azo initiators like azobisisobutyronitrile (AIBN), while also azo compounds, would be classified under different subheadings within Heading 2927, such as 2927.00.10 for AIBN in the HTSUS, or other relevant national subdivisions. Similarly, mixtures containing 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile) but with other active components or in forms not considered "pure" for Chapter 29 purposes might be classified elsewhere, potentially in Chapter 38 if they are preparations.
What are common classification mistakes for HS 292700?
A common error is misclassifying other azo compounds, particularly other azo polymerization initiators, under HS 292700 due to a general understanding of their chemical function rather than their precise chemical structure. Importers might incorrectly assume that all similar azo-nitrile initiators belong here. This mistake often arises from failing to strictly apply 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. The specific chemical name and CAS RN are paramount for this subheading, and any deviation means it falls outside this precise classification.
How should importers classify products under HS 292700?
The correct procedure for classifying products under HS 292700 involves a rigorous verification of the chemical identity. Importers and customs brokers must ensure that the product is unequivocally 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile) by cross-referencing its chemical name, CAS RN 15545-97-8, and molecular structure against technical specifications, safety data sheets (SDS), and certificates of analysis. Applying GRI 1, the specific terms of Heading 2927 and subheading 292700 must be met exactly. If there is any doubt, seeking a binding ruling from the relevant customs authority (e.g., CBP in the US, HMRC in the UK) is advisable to ensure compliance and avoid potential penalties.

Based on common trade agreements, 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile) may be eligible for 'Free' duty under agreements with countries such as 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), among others. Importers should verify the specific trade agreement and rules of origin requirements for their destination country to claim preferential treatment.
What documentation is typically required for importing 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile) under HS 2927.00?
Standard import documentation for 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile) under HS 2927.00 generally includes a commercial invoice, packing list, bill of lading or air waybill, and a certificate of origin. Given its chemical nature, a Safety Data Sheet (SDS) is almost always required for hazard communication and regulatory compliance. Depending on the importing country's chemical control regulations, additional permits or declarations (e.g., under TSCA in the US, REACH in the EU) may be necessary. Importers should consult the specific requirements of the destination customs authority and relevant chemical regulatory bodies.
Are there any specific trade agreements that frequently offer duty benefits for chemical compounds like 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile) classified under HS 2927.00?
Yes, numerous Free Trade Agreements (FTAs) and preferential trade programs frequently offer duty benefits for chemical compounds, including those under HS 2927.00. For instance, agreements like the US-Korea Free Trade Agreement (KORUS FTA), the US-Australia Free Trade Agreement (AUSFTA), and various Generalized System of Preferences (GSP) programs (though GSP eligibility can vary by product and country) often provide 'Free' duty rates. The specific eligibility for 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile) depends on meeting the Rules of Origin criteria specified within each agreement. Importers should consult the text of the relevant trade agreement and obtain a valid Certificate of Origin to substantiate claims for preferential duty treatment.
