HS 390290 Other
Quick Answer: Other polymers of propylene imported under HS 390290 enter the UK with rates ranging from 0.00% to 6.00%, the EU at 0.00%, and the US at 6.5% or a specific duty of 2.2¢/kg + 33.5%. This residual classification applies to polymers of propylene not specifically listed elsewhere in Chapter 39. Importers should carefully review the specific polymer's characteristics and any applicable preferential trade agreements, as duty rates can vary significantly. CustomTariffs aggregates this data, highlighting the importance of precise classification for accurate duty assessment.

How to Classify This HS Code?
What products does HS 390290 cover?
This subheading covers other polymers of propylene, in primary forms, not specifically enumerated under HS 3902.10 (polypropylene) or HS 3902.20 (polyisobutylene). According to the World Customs Organization (WCO) Harmonized System Explanatory Notes and definitions found in official tariff schedules like the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC, this category includes copolymers of propylene with other monomers where propylene is the predominant constituent, as well as modified propylene polymers and mixtures of propylene polymers with additives, provided they remain in their primary forms such as granules, powders, or liquids.
What falls outside HS 390290?
The following products are excluded from HS 390290: pure polypropylene (HS 3902.10), pure polyisobutylene (HS 3902.20), and finished articles manufactured from these polymers, such as plastic films, sheets, pipes, or molded goods. Also excluded are polymers of other olefins or copolymers of other olefins with propylene where propylene is not the predominant constituent. For instance, ethylene-propylene copolymers where ethylene is the primary monomer would be classified under a different heading, typically within Chapter 39.
What are common classification mistakes for HS 390290?
A common error is misclassifying copolymers where propylene is not the predominant monomer. General Interpretative Rule 1 (GIR 1) for the interpretation of the Harmonized System states that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. Importers may also incorrectly classify finished or semi-finished goods under this subheading, overlooking the requirement for products to be in their "primary forms" as defined by Chapter 39 Notes.
How should importers classify products under HS 390290?
The correct procedure for classifying products under HS 390290 involves a thorough review of the product's chemical composition and physical form. Importers and customs brokers must ascertain if the polymer is primarily derived from propylene and if it is in a primary form (e.g., granules, powders, flakes, or bulk liquids). Consulting the WCO HS Explanatory Notes and the specific tariff schedule of the importing country, such as the USITC HTS or EU TARIC, is crucial for accurate determination.
How is the duty calculated for products under HS 390290?
A shipment of 10,000 kilograms of propylene-ethylene copolymer granules, declared at a customs value of $15,000 USD, would attract a US duty of $750.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value ($15,000 USD × 0.05 = $750.00). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule for HS code 3902.90.90.
Which trade agreements reduce duties for HS 390290?
Several free trade agreements may reduce the applicable duty rate for HS 390290, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating goods from Canada and Mexico can benefit from a duty rate of Free. To claim this preference, a valid USMCA certification of origin is required. Additionally, certain developing countries may benefit from preferential rates under the Generalized System of Preferences (GSP), often requiring a GSP Form A. The specific preferential rate and documentation requirements vary by country and agreement.

FAQ
What is the general import duty rate for HS code 390290?
The Most Favored Nation (MFN) duty rate for HS code 390290, which covers 'Other' polymers of propylene or of other olefins, not elsewhere specified, is 6.00% ad valorem in the United States. This rate is applied to the declared customs value of the imported goods. Always verify the most current rates on the US International Trade Commission (USITC) website, as tariff schedules can be updated.
How are preferential duty rates applied to HS 390290 under trade agreements?
Various trade agreements offer preferential duty rates for HS code 390290. For example, under the US Free Trade Agreement with Australia (AU), the duty rate is Free. Other agreements, such as those with Chile (CL), South Korea (KR), and Singapore (SG), also provide duty-free entry. To claim these preferential rates, importers must provide a valid Certificate of Origin and ensure the goods meet the rules of origin stipulated in the respective trade agreement. Consult the specific trade agreement text or the USITC's Harmonized Tariff Schedule for detailed eligibility and requirements.
What are the classification criteria for products falling under HS code 390290?
HS code 390290 is a residual category for 'Other' polymers of propylene or of other olefins, not specified elsewhere in Chapter 39. This means it applies to polymers of propylene, or copolymers where propylene is the monomer of chief weight, and other olefins, that do not fit into more specific headings like 3902.10 (Polypropylene) or 3902.20 (Polyisobutylene). Classification relies on the chemical composition and structure of the polymer, often requiring laboratory analysis or detailed product specifications to differentiate it from other polymer classifications.
How is the import duty calculated for HS 390290 when a specific duty rate is involved?
While many rates for HS 390290 are ad valorem (a percentage of the value), some countries may have specific duties or a combination. For instance, if a hypothetical rate were 2.2¢/kg + 33.5% ad valorem, the calculation would involve both weight and value. Example: If you import 1,000 kg of goods valued at $5,000 USD, the duty would be (1,000 kg * $0.022/kg) + (0.335 * $5,000 USD) = $22 + $1,675 = $1,697. Importers and brokers must carefully check the specific duty calculation method for the destination country's tariff schedule.
What documentation is typically required for importing goods classified under HS 390290?
Standard import documentation for HS 390290 includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the country of import and any claimed preferential treatment, a Certificate of Origin may be mandatory. For polymers, specific chemical composition details or Safety Data Sheets (SDS) might be requested by customs authorities to verify classification and ensure compliance with any chemical import regulations. Always confirm the exact requirements with the customs authority of the importing country.
