How to Classify This HS Code?

```html

What products does HS 845510 cover?

This subheading covers "Tube mills," which are specialized machines designed for the continuous production of seamless or welded tubes and pipes from metal. 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's TARIC, these mills typically perform operations such as rolling, drawing, or welding to form tubular products. They are distinct from machines that merely cut or finish pre-formed tubes.

What falls outside HS 845510?

The following products are excluded from HS 845510: machines for the manufacture of tubes and pipes of cement, of ceramics, or of plastics, which are classified under their respective material chapters. Additionally, machines that perform only secondary operations on tubes, such as cutting, bending, threading, or straightening, are generally classified under other headings within Chapter 84, depending on their primary function. For example, a pipe cutting machine would not be classified here.

What are common classification mistakes for HS 845510?

A common error is misclassifying machines that perform ancillary functions as tube mills. For instance, machines that are primarily designed for finishing, coating, or testing tubes, rather than their initial formation, may be incorrectly entered under this subheading. Adherence to General Rule of Interpretation (GRI) 3(b) for composite goods or GRI 1 for the essential character of the machine is crucial to avoid misclassification, ensuring the machine's primary purpose of tube formation is correctly identified.

How should importers classify products under HS 845510?

The correct procedure for classifying products under HS 845510 involves a thorough examination of the machine's design, function, and the primary operation it performs. Importers and customs brokers should consult the official tariff schedule of the importing country, such as the USITC HTS or the UK Trade Tariff, and review the Explanatory Notes from the WCO. Verifying that the machine is specifically designed for the continuous production of tubes or pipes from raw metal is paramount.

How is the duty calculated for products under HS 845510?

A seamless tube rolling mill, declared at a customs value of $500,000 USD, would attract a US duty of $25,000. This is calculated using the Most Favored Nation (MFN) rate of 5.0% ad valorem, as published in the USITC Harmonized Tariff Schedule. The calculation is: 5.0% × $500,000 = $25,000. This rate applies to goods from countries not benefiting from preferential trade agreements.

Which trade agreements reduce duties for HS 845510?

Several free trade agreements may reduce the applicable duty rate for HS 845510, 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. For goods originating from the United Kingdom, a preferential rate of Free may apply under the UK-US Free Trade Agreement (once ratified and in force). Documentation required typically includes a self-certified origin statement for USMCA or a specific origin declaration for other agreements.

FAQ

What is the standard import duty rate for HS code 845510 (Tube mills)?

The standard Most Favored Nation (MFN) duty rate for tube mills, classified under HS code 845510, is 2.70% ad valorem in the United States. This rate applies to goods imported from countries that do not have a specific preferential trade agreement with the U.S. Always consult the latest Harmonized Tariff Schedule of the United States (HTSUS) maintained by the USITC for the most current and precise duty information.

How is the import duty for a tube mill calculated under HS 845510?

The duty for HS 845510 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the imported goods. For example, if a tube mill is valued at $100,000 and the MFN duty rate is 2.70%, the import duty would be $100,000 \times 0.0270 = $2,700. It is crucial to ensure accurate valuation of the imported goods as per U.S. Customs and Border Protection (CBP) regulations.

Are there any preferential duty rates available for tube mills (HS 845510) under trade agreements?

Preferential duty rates for HS code 845510 depend on the country of origin and applicable trade agreements. For instance, goods originating from countries with a Free Trade Agreement (FTA) with the United States, such as Mexico or Canada under the United States-Mexico-Canada Agreement (USMCA), may be eligible for a 0.00% duty rate, provided they meet the rules of origin. Importers must possess valid proof of origin documentation to claim these preferential rates. Always verify eligibility and requirements with the specific trade agreement and CBP.

What are the key classification criteria for classifying machinery as a 'Tube mill' under HS 845510?

HS code 845510 specifically covers 'Tube mills' which are machines designed for the production of tubes or pipes, typically through processes like rolling, drawing, or extrusion of metal. The primary function of the machinery must be the continuous forming and shaping of tubes or pipes from raw materials. Machinery for cutting, finishing, or welding pre-formed tubes may fall under different HS codes. Consult the Explanatory Notes to the Harmonized System (WCO) and the HTSUS for detailed guidance on classification criteria.

What documentation is typically required when importing tube mills under HS 845510?

When importing tube mills under HS 845510, standard import documentation is required, including a commercial invoice, packing list, and bill of lading. Additionally, depending on the country of origin and any claimed preferential treatment, a Certificate of Origin or other proof of origin documentation may be necessary. For machinery, technical specifications or manuals may also be requested by customs authorities to verify classification and compliance. It is advisable for importers and customs brokers to confirm specific documentation requirements with the importing country's customs agency.
