How to Classify This HS Code?
What products does HS 401036 cover?
This subheading covers endless synchronous belts made of rubber or textile materials, specifically those with an outside circumference exceeding 150 cm but not exceeding 198 cm. According to the World Customs Organization (WCO) Harmonized System Nomenclature, these belts are designed for positive power transmission, featuring teeth or cogs that mesh with pulleys, ensuring precise speed and timing. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this scope, focusing on the material composition and the specified dimensional range for synchronous belts.
What falls outside HS 401036?
The following products are excluded from HS 401036: synchronous belts with an outside circumference outside the specified range of 150 cm to 198 cm, such as those shorter or longer than these limits. Also excluded are non-synchronous belts (e.g., V-belts or flat belts) which do not have teeth for positive engagement, as well as belts made from materials other than rubber or textile reinforcement, or those that are not endless (i.e., have a splice). For example, a synchronous belt with a 200 cm circumference would be classified elsewhere under HS 401039.
What are common classification mistakes for HS 401036?
A common error is misinterpreting the "endless" requirement or the circumference measurement. Importers may incorrectly classify spliced belts or belts where the circumference measurement is taken incorrectly (e.g., internal instead of external). According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the heading and any relative section or chapter notes. Failing to accurately measure the outside circumference, which must be between 150 cm and 198 cm inclusive, is a frequent oversight leading to misclassification.
How should importers classify products under HS 401036?
The correct procedure for classifying products under HS 401036 involves verifying the material composition (rubber or textile reinforced rubber) and, crucially, measuring the exact outside circumference of the belt. Importers and customs brokers must ensure this measurement falls within the 150 cm to 198 cm range. Consulting the product’s technical specifications and comparing them against the WCO HS Explanatory Notes and relevant national tariff schedules, such as the USITC HTS or UK Trade Tariff, is essential for accurate classification.
How is the duty calculated for products under HS 401036?
A specific product, a "Gates PowerGrip GT3 synchronous belt" with an outside circumference of 180 cm, weighing 0.5 kg and declared at a customs value of $100 USD, would attract a US duty of $4.00. This is calculated using the USITC Harmonized Tariff Schedule's Most Favored Nation (MFN) rate of 4.0% ad valorem, applied to the declared customs value ($100 USD × 4.0% = $4.00). Note that if the belt were classified by weight, the calculation would differ based on the specific unit rate.
Which trade agreements reduce duties for HS 401036?
Several free trade agreements may reduce the applicable duty rate for HS 401036, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, belts originating from Canada or Mexico may enter the US duty-free if they meet the rules of origin. To claim this preference, a self-certified origin statement is typically required. Additionally, belts originating from countries benefiting from the US Generalized System of Preferences (GSP) program may also receive preferential duty rates, often requiring a GSP Form A.

FAQ
What are the import duty rates for HS code 401036, covering endless synchronous belts with an outside circumference between 150 cm and 198 cm?
The Most Favored Nation (MFN) duty rate for HS code 401036 is typically 6.50% ad valorem. However, preferential duty rates may apply under various trade agreements. For example, under the US-Australia Free Trade Agreement (AU), the rate is Free. Under the US-Korea Free Trade Agreement (KR), the rate is also Free. It is crucial to consult the specific trade agreement and the relevant customs authority (e.g., USITC for the US, EU TARIC for the EU, UK Trade Tariff for the UK) for the most current and applicable rates based on the country of origin and any specific conditions.
What specific criteria define an 'endless synchronous belt' under HS code 401036?
HS code 401036 specifically covers 'endless synchronous belts' made of rubber or plastics, characterized by their continuous loop construction (endless) and designed for transmitting power with synchronized movement (synchronous). The key classification criterion for this specific subheading is the outside circumference, which must exceed 150 cm but not exceed 198 cm. Belts that do not meet these dimensional requirements or lack the synchronous tooth pattern would be classified under different subheadings within HS 4010.
How is the import duty for HS code 401036 calculated, and can you provide an example?
The import duty for HS code 401036 is generally calculated on an ad valorem basis, meaning it is a percentage of the declared customs value of the goods. For instance, if the MFN duty rate is 6.50% and a shipment of these belts has a declared customs value of $10,000, the duty would be calculated as: $10,000 (Value) × 0.065 (Duty Rate) = $650.00 (Duty Amount). If specific duties (e.g., per unit) were applicable, the calculation would involve multiplying the rate per unit by the number of units imported. Always verify the applicable duty basis (ad valorem, specific, or compound) with the customs authority.
What documentation is typically required when importing endless synchronous belts classified under HS 401036?
Standard import documentation for HS code 401036 generally includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list; a bill of lading or air waybill; and a certificate of origin. Depending on the country of import and any specific trade agreements being claimed, additional documentation might be required to substantiate preferential duty rates. This could include proof of origin certificates or manufacturer declarations. Importers and customs brokers should consult the importing country's customs regulations for a comprehensive list.
Which common trade agreements offer preferential duty rates for HS code 401036, and how can importers benefit?
Several trade agreements can offer reduced or free entry for goods classified under HS 401036. Examples include the USMCA (United States-Mexico-Canada Agreement), CAFTA-DR (Dominican Republic-Central America Free Trade Agreement), and various bilateral FTAs (Free Trade Agreements) such as those with South Korea (KR), Australia (AU), and Singapore (SG). To benefit, importers must ensure the belts meet the rules of origin stipulated in the specific agreement and possess the correct documentation (e.g., Certificate of Origin) to prove their eligibility. Consulting the official trade agreement text and customs rulings is essential for accurate application.
