HS 903289 Other
Quick Answer: Automatic regulating or controlling instruments and apparatus imported under HS 903289 enter the UK at 2.00%, the EU at 2.80%, and the US at 1.1% (MFN). This residual classification applies to automatic regulating or controlling instruments and apparatus not specifically covered by other headings within Chapter 90 of the Harmonized System. This can include a wide array of devices, such as thermostats, pressure regulators, and humidity controllers, used in various industrial, commercial, and domestic applications. Importers should carefully review the specific product's function to ensure it does not fall under a more precise HS code, as misclassification can lead to delays and penalties. According to CustomTariffs data, the US also offers duty-free entry for certain trade partners under this code.

How to Classify This HS Code?
What products does HS 903289 cover?
This subheading covers automatic regulating or controlling instruments and apparatus not elsewhere specified or included in heading 9032, which are designed for the automatic adjustment of a variable to a predetermined value, or for maintaining such value. According to the 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 encompasses a broad range of devices, including but not limited to, pressure regulators, temperature controllers, and flow meters that operate automatically without direct human intervention to maintain a specific setpoint, provided they do not fit into more specific subheadings within 9032.
What falls outside HS 903289?
The following products are excluded from HS 903289: instruments and apparatus for automatically controlling industrial processes (which may fall under more specific headings), manually operated regulating or controlling instruments, and devices that are primarily for measurement rather than automatic regulation. For instance, simple thermometers without automatic adjustment capabilities, manual valves, or basic pressure gauges that only display readings without controlling a system are not classified here. Items that are integral parts of machines or appliances and perform a regulating function specific to that machine are also typically classified with the machine itself.
What are common classification mistakes for HS 903289?
A common error is misinterpreting the "automatic regulating or controlling" aspect, leading to the classification of manual devices or simple measuring instruments under this subheading. Another mistake involves failing to consider the General Rules for the Interpretation of the Harmonized System (GRI), particularly GRI 3, which dictates that when goods are classifiable by virtue of being described in more than one heading or subheading, classification shall be effected at the most specific subheading. Importers may also incorrectly classify components that are part of a larger automatic regulating system under this code instead of the complete apparatus.
How should importers classify products under HS 903289?
The correct procedure for classifying products under HS 903289 involves a thorough examination of the product's primary function. Importers and customs brokers must determine if the apparatus automatically regulates or controls a variable to a predetermined value or maintains it. Consulting the official tariff schedule, such as the USITC HTS or the EU TARIC, and reviewing the Explanatory Notes for heading 9032 is crucial. If the product's function aligns with the description and it is not specifically covered elsewhere, then HS 903289 is the appropriate classification.
How is the duty calculated for products under HS 903289?
A digital thermostat for controlling HVAC systems, declared at a customs value of $50 USD, would attract a US duty of $3.50. This is calculated using the Most Favored Nation (MFN) duty rate of 7.0% ad valorem, as published in the USITC Harmonized Tariff Schedule for a similar product, applied to the declared value ($50 USD × 0.07 = $3.50). It is imperative to verify the exact rate applicable to the specific product and its country of origin.
Which trade agreements reduce duties for HS 903289?
Several free trade agreements may reduce the applicable duty rate for HS 903289, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying goods originating from Canada or Mexico. Additionally, the Generalized System of Preferences (GSP) may offer reduced or Free duty rates for eligible goods from designated developing countries. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a GSP Form A for GSP benefits, depending on the specific agreement and jurisdiction.

FAQ
What are the typical import duty rates for HS code 903289?
HS code 903289, designated for 'Other automatic regulating or controlling instruments and apparatus', has varied duty rates depending on the importing country. For example, the U.S. Most Favored Nation (MFN) rate is 2.80% ad valorem. The EU's TARIC system may show different rates, and the UK Trade Tariff also lists specific duties. It is crucial to consult the specific tariff schedule of the destination country for the exact rate applicable to your import.
How is the import duty for HS code 903289 calculated, and can you provide an example?
The duty calculation for HS code 903289 is typically based on the ad valorem method, meaning a percentage of the declared customs value of the goods. For instance, if a shipment of goods classified under 903289 has a customs value of $10,000 and the applicable duty rate is 2.80%, the import duty would be calculated as: $10,000 (Customs Value) × 0.0280 (Duty Rate) = $280. Always verify the specific valuation rules and any potential additional duties or taxes applicable in the importing country.
What preferential duty rates are available for HS code 903289 under trade agreements?
Preferential duty rates for HS code 903289 can be significant under various Free Trade Agreements (FTAs). For instance, under certain agreements, rates can be as low as Free (e.g., for specific partner countries like Australia (AU), Canada (C), Chile (CL), South Korea (KR), Singapore (SG), and others as indicated by the 'Free (A,AU,B,BH,C,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG)' notation). To claim these preferential rates, importers must provide a valid Certificate of Origin or other proof of eligibility as required by the specific trade agreement and the importing country's customs authority.
What are the classification criteria for goods falling under HS code 903289?
HS code 903289 is a residual category for automatic regulating or controlling instruments and apparatus not specifically covered by more precise headings within Chapter 90 of the Harmonized System. Classification hinges on whether the article is an instrument or apparatus designed to automatically maintain a physical quantity (like temperature, pressure, humidity, or flow) at a desired set point, and it must not be specifically enumerated elsewhere. Importers should first attempt to classify their goods under more specific HS codes before resorting to 903289. Consulting the Explanatory Notes to the Harmonized System and the rulings of the relevant customs authority is advisable.
What documentation is typically required for importing goods under HS code 903289?
Standard import documentation for HS code 903289 generally includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the specific nature of the 'other' instrument or apparatus, additional documentation may be required. This could include technical specifications, product brochures, safety certifications (e.g., CE marking for EU), or a declaration of conformity. If claiming preferential duty rates, a Certificate of Origin is mandatory. Importers should always verify the specific documentation requirements with the customs authority of the importing country.
