HS 400241 Chloroprene (chlorobutadiene) rubber (CR)
Quick Answer: Chloroprene rubber (CR) imported under HS 400241 enters the UK at 0.00%, the EU at 0.00%, and the US at a duty-free rate under the Most Favored Nation (MFN) tariff. This classification specifically covers chloroprene (chlorobutadiene) rubber, a synthetic rubber known for its resistance to oil, heat, and weathering, commonly used in applications like hoses, belts, and wetsuits. Importers should be aware that while the UK and EU offer duty-free entry, the US has a 20% MFN rate in addition to the free rate, requiring careful consideration of origin and specific tariff provisions. CustomTariffs aggregates this information, highlighting potential cost differences across major markets.

How to Classify This HS Code?
What products does HS 400241 cover?
This subheading covers chloroprene (chlorobutadiene) rubber (CR), which is a synthetic rubber produced by the polymerization of chloroprene. According to the World Customs Organization's Harmonized System Nomenclature, this category specifically includes homopolymers of chloroprene. Official definitions from sources like the US International Trade Commission (USITC) and the EU's TARIC database confirm that this classification applies to the raw, uncompounded polymer, often supplied in bales or sheets, and is distinct from finished rubber articles.
What falls outside HS 400241?
The following products are excluded from HS 400241: synthetic rubbers other than chloroprene homopolymers, such as styrene-butadiene rubber (SBR) or polybutadiene rubber (BR), which are classified under other subheadings of heading 4002. Also excluded are compounded rubbers containing additives like carbon black, fillers, or vulcanizing agents, as these are typically classified under heading 4005. Finished rubber articles, such as tires, hoses, or seals, are also excluded and fall under their respective chapters or headings in the HS nomenclature.
What are common classification mistakes for HS 400241?
A common error is misclassifying compounded chloroprene rubber as HS 400241. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes. If a product is a mixture or compound of different materials, it should be classified according to GRI 3. For chloroprene rubber that has been mixed with other substances, it would likely fall under heading 4005, not 400241, unless the other substances are present in minimal quantities and do not alter the essential character of the rubber.
How should importers classify products under HS 400241?
The correct procedure for classifying products under HS 400241 involves a thorough examination of the product's composition and form. Importers and customs brokers must verify that the product is indeed a homopolymer of chloroprene and has not undergone significant compounding or processing. Reviewing the supplier's technical data sheets and product specifications is crucial. If the product is a blend or contains additives, further investigation into heading 4005 or other relevant headings is necessary, referencing official tariff databases like the USITC HTS or EU TARIC for definitive guidance.
How is the duty calculated for products under HS 400241?
A shipment of 10,000 kilograms of Neoprene brand chloroprene rubber, declared at a customs value of $25,000 USD, would attract a US duty of $3,750. This is calculated using the Most Favored Nation (MFN) duty rate of 15% ad valorem, applied to the declared customs value ($25,000 USD × 0.15 = $3,750). This calculation is based on the rates published in the USITC Harmonized Tariff Schedule (HTS) for subheading 4002.41.0000.
Which trade agreements reduce duties for HS 400241?
Several free trade agreements may reduce the applicable duty rate for HS 400241. For example, under the United States-Mexico-Canada Agreement (USMCA), originating chloroprene rubber from Canada or Mexico may enter duty-free. Similarly, preferential rates may apply under agreements with countries like South Korea. To claim these preferences, a valid USMCA Certificate of Origin or a supplier's declaration of origin, depending on the specific agreement and jurisdiction, is typically required. The specific preferential rate can be as low as "Free" for qualifying originating goods.

FAQ
What are the typical import duty rates for Chloroprene (chlorobutadiene) rubber (CR) under HS code 400241?
The Most Favored Nation (MFN) duty rate for HS code 400241, Chloroprene (chlorobutadiene) rubber (CR), is 0.00% ad valorem in the United States. However, preferential rates may apply. For instance, under the Generalized System of Preferences (GSP), the rate is also 0.00%. It is crucial to consult the latest US International Trade Commission (USITC) Harmonized Tariff Schedule for the most current rates and any specific country of origin requirements. For imports into the European Union, the TARIC database indicates a duty rate of 0.00% ad valorem. In the United Kingdom, the UK Trade Tariff also lists a duty rate of Free (0.00%) for this classification.
How is Chloroprene (chlorobutadiene) rubber (CR) classified under HS code 400241, and what are the key criteria?
HS code 400241 specifically covers 'Chloroprene (chlorobutadiene) rubber (CR), whether or not prevulcanized'. The primary classification criterion is the chemical composition. The product must be a synthetic rubber derived from the polymerization of chloroprene. Prevulcanized forms, which have undergone an initial vulcanization process to improve handling and processing, are also included under this code. Importers must ensure that the product's technical specifications and chemical analysis confirm it is indeed chloroprene rubber to avoid misclassification. Referencing the World Customs Organization (WCO) Explanatory Notes for Chapter 40 can provide further clarification on the characteristics of synthetic rubbers.
What documentation is typically required for importing Chloroprene (chloroprene) rubber (CR) under HS code 400241?
Standard import documentation for HS code 400241 includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the country of importation and the origin of the goods, a Certificate of Origin may be required, especially if preferential duty rates are claimed. For chemical products like chloroprene rubber, a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) is often necessary for safety and regulatory compliance. Customs brokers should verify specific requirements with the importing country's customs authority, such as U.S. Customs and Border Protection (CBP) or HM Revenue & Customs (HMRC) in the UK, as additional certifications or declarations might be mandated.
Are there common trade agreements that might offer reduced or zero duty rates for Chloroprene (chloroprene) rubber (CR) imported under HS code 400241?
Yes, several trade agreements can impact the duty rates for HS code 400241. For imports into the United States, the Generalized System of Preferences (GSP) may offer duty-free entry for eligible goods from developing countries. While the MFN rate is already 0.00%, understanding GSP eligibility is important for potential future tariff changes. For imports into the European Union, agreements with specific countries might offer preferential treatment. Similarly, the UK has various trade agreements post-Brexit that could affect duties. Importers should consult the relevant preferential trade agreement schedules for the importing country and verify the origin of their goods to determine eligibility for reduced or zero duties.
How is the import duty for Chloroprene (chloroprene) rubber (CR) calculated if a duty rate other than 0.00% applies? Provide a numerical example.
While the MFN duty rate for HS 400241 is typically 0.00% in major markets like the US, EU, and UK, let's illustrate a calculation assuming a hypothetical scenario where a 5% ad valorem duty applies. If an importer brings in 10,000 kilograms of Chloroprene rubber valued at $2.50 per kilogram, the total value of the shipment is 10,000 kg * $2.50/kg = $25,000. The duty calculation would be: Duty = Value of Goods × Duty Rate. In this hypothetical case, Duty = $25,000 × 5% (or 0.05) = $1,250. This $1,250 would be the ad valorem duty payable. It is crucial to use the correct Harmonized System code and consult the specific tariff schedule of the importing country to ascertain the applicable duty rate and calculation method.
