How to Classify This HS Code?
What products does HS 390890 cover?
This subheading covers "Other" polyamides in primary forms, not elsewhere specified within Heading 3908. According to the World Customs Organization (WCO) Harmonized System Explanatory Notes, this category is a residual one for polyamides that do not fit the more specific subheadings for polyamide-6,6 and other polyamides. The US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that this code applies to various other polyamides in their raw, unprocessed states, such as powders, granules, or blocks, when not specifically listed elsewhere.
What falls outside HS 390890?
The following products are excluded from HS 390890: specifically enumerated polyamides like polyamide-6,6 (HS 390810) and other specified polyamides (HS 390890). Also excluded are finished or semi-finished articles made from polyamides, such as woven fabrics (Chapter 54), knitted fabrics (Chapter 60), or plastic articles like ropes, cords, or molded parts (Chapter 39, other headings). For instance, polyamide fibers or yarns would be classified under Chapter 54, not this heading.
What are common classification mistakes for HS 390890?
A common error is misclassifying modified polyamides or copolymers under this subheading when they should be classified based on their primary constituent or under a more specific heading if provided for. For example, if a polyamide is significantly modified with other polymers, it might fall under a different heading. Importers may also mistakenly classify semi-finished or finished goods, such as extruded rods or sheets, under this heading instead of a more appropriate heading for plastic shapes or articles.
How should importers classify products under HS 390890?
The correct procedure for classifying products under HS 390890 involves first identifying the material as a polyamide in its primary form. Then, consult the WCO Harmonized System Explanatory Notes and the specific tariff schedule of the importing country (e.g., USITC HTS, EU TARIC, UK Trade Tariff) to ensure it is not specifically enumerated in a preceding subheading of Heading 3908. If it is a polyamide in primary form and not otherwise specified, it should be classified here. Customs brokers should verify the chemical composition and physical form with the manufacturer.
How is the duty calculated for products under HS 390890?
A shipment of 1,000 kilograms of unspecified polyamide granules, declared at a customs value of $5,000 USD, would attract a US duty of $175.00. This is calculated using the Most Favored Nation (MFN) duty rate of 3.5% ad valorem, applied to the declared customs value ($5,000 USD × 0.035 = $175.00). This calculation is based on the rates published in the USITC Harmonized Tariff Schedule for HS code 390890.
Which trade agreements reduce duties for HS 390890?
Several free trade agreements may reduce the applicable duty rate for HS 390890, including the United States-Mexico-Canada Agreement (USMCA), which can result in a 0% duty rate for qualifying goods originating from Canada or Mexico. The Generalized System of Preferences (GSP) may also offer reduced or duty-free entry for eligible goods from certain developing countries. To claim preference under USMCA, a self-certified origin statement is typically required. For GSP, a GSP Form A is usually needed.

FAQ
What are the import duty rates for HS code 390890?
HS code 390890 covers 'Other' polyamides in primary forms. The Most Favored Nation (MFN) duty rate in the United States is 6.5% ad valorem. However, preferential rates may apply under various trade agreements. For instance, goods originating from Australia (AU) may be eligible for a Free rate. It is crucial to consult the latest USITC Harmonized Tariff Schedule for the most current and specific rates applicable to your country of origin.
How is the duty calculated for HS code 390890?
The duty for HS code 390890 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared value of the imported goods. For example, if the MFN duty rate is 6.5% and you import polyamide valued at $10,000, the duty would be $10,000 * 0.065 = $650. Always ensure your customs value is accurately declared according to the transaction value method, as per U.S. Customs and Border Protection (CBP) regulations.
What are the classification criteria for goods under HS code 390890?
HS code 390890 is an 'Other' category, meaning it applies to polyamides in primary forms (powders, granules, flakes, etc.) that are not specifically listed under other subheadings within heading 3908. Heading 3908 specifically covers polyamides, whether or not modified. To classify under 390890, the material must be a polyamide and not fit into more specific classifications like 3908.10 (polyamide-6,6 and its polyamides, unmoddnified) or 3908.90 (other polyamides).
Which trade agreements commonly offer preferential duty rates for HS code 390890?
Several trade agreements can provide preferential duty rates for goods classified under HS code 390890. Examples include agreements with countries like Australia (AU), Chile (CL), and South Korea (KR), which may offer Free or reduced duty rates depending on the specific terms of the agreement and the origin of the goods. Importers should verify the origin of their goods and consult the relevant preferential trade program documentation, such as Certificates of Origin, to claim these benefits.
What documentation is typically required for importing polyamides under HS code 390890?
Standard documentation for importing polyamides under HS code 390890 includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the country of origin and any claimed preferential duty rates, a Certificate of Origin may be required. For certain polyamides, specific declarations regarding their composition or intended use might also be necessary to ensure compliance with U.S. Food and Drug Administration (FDA) or other agency requirements if applicable. Always check with U.S. Customs and Border Protection (CBP) for the most up-to-date requirements.
