HS 701720 Of other glass having a linear coefficient of expansion not exceeding 5 × 10$-6 per Kelvin within a temperature range of 0 °C to 300 °C

What products does HS 701720 cover?

This subheading covers laboratory, hygienic, or pharmaceutical glassware made of glass with a linear coefficient of expansion not exceeding 5 × 10<sup>-6</sup> per Kelvin within a temperature range of 0 °C to 300 °C. As per the World Customs Organization's Harmonized System Explanatory Notes and the US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS), this includes items like specialized beakers, flasks, test tubes, and measuring instruments designed for scientific or medical applications where thermal stability is critical. The EU's TARIC database also confirms this scope, emphasizing the material's specific thermal properties.

What falls outside HS 701720?

The following products are excluded from HS 701720: general household glassware, decorative glass items, and laboratory glassware not meeting the specified linear coefficient of expansion. For instance, standard kitchen measuring cups made of soda-lime glass, which typically have a higher coefficient of expansion, would be classified elsewhere, likely under heading 7017.10 if for laboratory use or 7017.90 for other glass articles of heading 7017. Items made from plastics or other materials, even if serving a similar laboratory function, are also excluded.

What are common classification mistakes for HS 701720?

A common error is misinterpreting the critical technical specification of the linear coefficient of expansion. Importers may incorrectly assume that any glass item intended for laboratory use falls under this category without verifying the material's specific thermal properties. General Rules for the Interpretation of the Harmonized System (GRI) 1 and 3(b) are relevant here; classification is determined by the essential character of the good. Without proof of the specific coefficient, such as manufacturer specifications, classification may default to a more general subheading within 7017.

How should importers classify products under HS 701720?

The correct procedure for classifying products under HS 701720 involves a two-step process: first, confirm the product is indeed glassware intended for laboratory, hygienic, or pharmaceutical use. Second, and critically, verify that the glass used has a linear coefficient of expansion not exceeding 5 × 10<sup>-6</sup> per Kelvin within the specified temperature range. Importers and customs brokers must obtain technical documentation from the manufacturer, such as a certificate of analysis or material specification sheet, to substantiate this claim.

How is the duty calculated for products under HS 701720?

A borosilicate glass graduated cylinder, 100 ml capacity, declared at a customs value of $50 USD, would attract a US duty of $2.50. This is calculated using the Most Favored Nation (MFN) rate of 5% ad valorem published in the USITC Harmonized Tariff Schedule (HTS) for HS 701720 (e.g., HTSUS 7017.20.0000). The calculation is 5% of $50 USD, resulting in a duty of $2.50. This rate applies if no preferential trade agreement is invoked.

Which trade agreements reduce duties for HS 701720?

Several free trade agreements may reduce the applicable duty rate for HS 701720, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating goods from Canada and Mexico can enter the US duty-free. For example, originating laboratory glassware from Mexico would be subject to a 0% duty rate. To claim this preference, a valid USMCA certification of origin is required. The UK also has agreements that could offer preferential rates for originating goods from certain countries.
