How to Classify This HS Code?

What products does HS 390810 cover?

This subheading covers polyamides in primary forms, specifically those of the polyamide-6, -11, -12, -6,6, -6,9, -6,10, or -6,12 types. According to the World Customs Organization (WCO) Harmonized System Nomenclature, these are synthetic linear polymers containing in the repeating unit, amide groups which link the methylene or other bivalent nucleous. The US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this scope, encompassing granules, powders, and blocks of these specific polyamide resins, often used in manufacturing textiles, automotive parts, and engineering plastics.

What falls outside HS 390810?

The following products are excluded from HS 390810: polyamides not specifically listed (e.g., polyamide-4,6), polyamides in forms other than primary forms such as finished articles (e.g., woven fabrics of polyamide, plastic pipes), and mixtures or compounds of polyamides with other substances where the polyamide is not the predominant component. For instance, polyamide fibers are classified under Chapter 54, and plastic articles of polyamide are typically found in Chapter 39, but under different headings or subheadings based on their specific form and use.

What are common classification mistakes for HS 390810?

A common error is misclassifying polyamide resins that are modified or compounded with significant amounts of other materials. According to General Interpretative Rule 1 and Rule 3(b) of the Harmonized System, the classification should be based on the essential character of the product. If a polyamide resin is blended with, for example, glass fibers to create a composite material, and the glass fiber content imparts the essential character, it may be classified elsewhere, potentially under Chapter 39 but in a different heading or subheading, or even under Chapter 70 if the glass is the predominant component by weight.

How should importers classify products under HS 390810?

The correct procedure for classifying products under HS 390810 involves a thorough examination of the product's chemical composition and physical form. Importers and customs brokers must consult the official tariff schedule of the importing country, such as the USITC HTS or the EU TARIC. Key steps include identifying the specific type of polyamide (e.g., polyamide-6,6), confirming it is in a primary form (granules, powder, etc.), and verifying that no other classification more specifically describes the good according to the General Rules for the Interpretation of the Harmonized System.

How is the duty calculated for products under HS 390810?

A shipment of 1,000 kilograms of Polyamide-6,6 granules, declared at a customs value of $5,000 USD, would attract a US duty of $350.00. This is calculated using the Most Favored Nation (MFN) duty rate of 7.0% ad valorem, applied to the declared customs value ($5,000 USD × 0.07 = $350.00). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule (HTS) for subheading 3908.10.0000.

Which trade agreements reduce duties for HS 390810?

Several free trade agreements may reduce the applicable duty rate for HS 390810. For goods originating from Mexico, Canada, or the United States, the United States-Mexico-Canada Agreement (USMCA) can provide duty-free entry, requiring a self-certified origin statement. For goods originating from certain developing countries, the Generalized System of Preferences (GSP) may offer duty-free entry, typically requiring a GSP Form A. The specific preferential rate and documentation requirements are jurisdiction-dependent and should be verified with the relevant customs authority.

FAQ

What are the typical import duty rates for Polyamide-6, -11, -12, -6,6, -6,9, -6,10 or -6,12 under HS code 390810?

The Most Favored Nation (MFN) duty rate for HS code 390810 (Polyamide-6, -11, -12, -6,6, -6,9, -6,10 or -6,12) in the United States is 6.5% ad valorem. However, preferential rates are available under various Free Trade Agreements (FTAs). For example, under the US-Australia FTA, the rate is Free (A). Importers should always verify the specific rate applicable to their country of origin and any relevant trade agreements. Consult the US International Trade Commission (USITC) Harmonized Tariff Schedule for the most current and detailed information.

How is the import duty calculated for HS 390810 if it has a compound duty rate?

While HS 390810 primarily carries an ad valorem rate in the US, some countries may have compound duties. A compound duty is a combination of an ad valorem rate (a percentage of the value) and a specific duty (a fixed amount per unit of weight or quantity). For example, if a hypothetical compound duty were 15.4¢/kg + 51.5% ad valorem, and you imported 100 kg of polyamide valued at $500, the duty would be calculated as follows: (15.4¢/kg * 100 kg) + (51.5% * $500). This would translate to ($15.40) + ($257.50) = $272.90. Always refer to the specific tariff schedule of the importing country for accurate calculation methods.

What are the key classification criteria for goods to be classified under HS code 390810?

HS code 390810 specifically covers 'Polyamide-6, -11, -12, -6,6, -6,9, -6,10 or -6,12'. The primary classification criterion is the chemical composition of the polymer. The material must be a polyamide, and specifically one of the listed types (e.g., Polyamide-6, commonly known as Nylon 6; Polyamide-6,6, commonly known as Nylon 6,6). The product can be in primary forms, such as powders, granules, flakes, or pellets. It is crucial to have technical documentation, like a Certificate of Analysis or a manufacturer's declaration, confirming the polymer type to ensure correct classification and avoid disputes with customs authorities.

Which trade agreements commonly offer preferential duty rates for HS 390810 into the United States?

Several trade agreements provide preferential duty rates for goods classified under HS 390810 into the United States. These include agreements with countries such as Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), South Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), and Singapore (SG), often resulting in a Free (0%) duty rate. To claim preferential treatment, importers must possess a valid Certificate of Origin or other documentation as required by the specific trade agreement. Always verify the current status and requirements of each agreement through official sources like the USITC.

What documentation is typically required for importing Polyamide under HS 390810?

When importing Polyamide under HS code 390810, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Crucially, to support the HS classification and potentially claim preferential duty rates, importers should also provide a Certificate of Analysis (CoA) or a manufacturer's declaration that specifies the type of polyamide (e.g., Polyamide-6, Polyamide-6,6) and confirms it is in primary form. If claiming preferential treatment under a Free Trade Agreement, a valid Certificate of Origin is mandatory. Customs brokers play a vital role in ensuring all necessary documents are accurate and submitted correctly to facilitate smooth customs clearance.
