Sight glass harmonized system code

Product Overview The Sight Glass, classified under Harmonized System (HS) Code 7015, is an essential industrial component employed in a variety of applications to enable visual monitoring of liquid flow and levels in processing systems. This product is specifically designed from heat-resistant borosilicate glass, ensuring durability and efficient functionality in high-temperature conditions. Within the HS Code 7015, Sight Glass falls under the subcategory of "Clock or watch glasses; glasses for non-corrective spectacles, curved, bent, hollowed or the like, not optically worked; hollow glass spheres and their segments, for the manufacture of such glasses." Commercially, Sight Glass is commonly used across food service, retail, processing industries, and beyond. Its primary value proposition lies in its transparent design, which facilitates real-time, non-invasive inspection of fluids in industrial systems, positioning it as a competitive solution for process monitoring and quality control. HS Code Classification & Trade Specifications The product is classified under the full six-digit HS Code structure as 7015.90, where the first two digits (70) represent the Chapter for "Glass and glassware," the next two digits (15) denote the Heading for "Clock or watch glasses; glasses for non-corrective spectacles," and the last two digits (90) specify the "Other" subheading, encompassing Sight Glass. This classification is justified by the product's physical properties and its commercial application. In terms of trade considerations, Sight Glass is typically packaged securely to prevent damage during transit, often using bubble wrap or foam padding, and preserved in moisture-free packaging to maintain its quality. Furthermore, it is crucial that these products comply with international quality standards such as ISO 9001 and ASTM E438, ensuring they meet the requirements of durability, chemical resistance, and heat tolerance. This product description is in compliance with World Trade Organization and customs documentation standards, providing all necessary technical and trade-related information to facilitate seamless global commerce.

Sight glass Chapter Note

1.- This Chapter does not cover : (a) Goods of heading 32.07 (for example, vitrifiable enamels and glazes, glass frit, other glass in the form of powder, granules or flakes); (b) Articles of Chapter 71 (for example, imitation jewellery); (c) Optical fibre cables of heading 85.44, electrical insulators (heading 85.46) or fittings of insulating material of heading 85.47; (d) Front windscreens (windshields), rear windows and other windows, framed, for vehicles of Chapters 86 to 88; (e) Front windscreens (windshields), rear windows and other windows, whether or not framed, incorporating heating devices or other electrical or electronic devices, for vehicles of Chapters 86 to 88; (f) Optical fibres, optically worked optical elements, hypodermic syringes, artificial eyes, thermometers, barometers, hydrometers or other articles of Chapter 90; (g) Luminaires and lighting fittings, illuminated signs, illuminated name-plates or the like, having a permanently fixed light source, or parts thereof of heading 94.05; (h) Toys, games, sports requisites, Christmas tree ornaments or other articles of Chapter 95 (excluding glass eyes without mechanisms for dolls or for other articles of Chapter 95); or (ij) Buttons, fitted vacuum flasks, scent or similar sprays or other articles of Chapter 96. 2.- For the purposes of headings 70.03, 70.04 and 70.05 : (a) glass is not regarded as “worked” by reason of any process it has undergone before annealing; (b) cutting to shape does not affect the classification of glass in sheets; (c) the expression “absorbent, reflecting or non-reflecting layer” means a microscopically thin coating of metal or of a chemical compound (for example, metal oxide) which absorbs, for example, infrared light or improves the reflecting qualities of the glass while still allowing it to retain a degree of transparency or translucency; or which prevents light from being reflected on the surface of the glass. 3.- The products referred to in heading 70.06 remain classified in that heading whether or not they have the character of articles. 4.- For the purposes of heading 70.19, the expression “glass wool” means : (a) Mineral wools with a silica (SiO2) content not less than 60 % by weight; (b) Mineral wools with a silica (SiO2) content less than 60 % but with an alkaline oxide (K2O or Na2O) content exceeding 5 % by weight or a boric oxide (B2O3) content exceeding 2 % by weight. Mineral wools which do not comply with the above specifications fall in heading 68.06. 5.- Throughout the Nomenclature, the expression “glass” includes fused quartz and other fused silica.
