Subject: Exclusion Request for Polymer Electrical Mountings Classified 8535.90.8040

 Determination of Action Pursuant to Section 301

S&C Electric Company (S&C-US) is headquartered in the USA with a wholly owned subsidiary 

in China, S&C Electric (China) Company Ltd. (S&C-China). S&C-China manufactures goods

primarily for the Chinese market, but also manufactures polymeric mountings (electrical 

connectors classified 8535.90.8040) for our global operations. A key component of this 

Mounting is the polymeric insulator (classified 8546.90.0000) which there are, globally, only 11 

known suppliers, with varying designs and differing quality levels. None of these 11 known 

suppliers are of US origin:i

S&C-US will continue purchasing/importing the Mountings from China due to the supply 

constraints in the industry. 

According to U.S. Imports for Consumption, 2017 and 2018 year-to-date, China is the top 

country that the U.S. has been importing products under HTSUS 8546.90.0000 (Electrical 

Insulators, Others). Polymeric Cutouts is one of sub-categories under HTS Code 

8546.90.0000. The report does not provide a detailed breakdown.ii

About S&C Electric Company

S&C specializes in the switching, protection, and control of electric power systems. Our 

solutions are an essential part of the electrical grid that brings power to homes and businesses. 

This started with a single product in 1909, the Liquid Power Fuse, which was the first reliable 

power fuse able to protect against the high currents in distribution substations. Its invention 

helped pioneer the widespread adoption and spread of electricity.

Today, we apply our century-long heritage of innovation to address the challenges facing today’s 

power grid. We push the boundaries of reliability by reducing the duration of power outages 

from hours to seconds — or to no outage at all. We are designing systems to withstand the 

impacts of time and nature to help keep the lights on for customers during major weather events. 

Our award-winning microgrid systems are providing breakthroughs in how distributed 

generation resources, including energy storage, solar, and wind, are managed by customers and 

their utility.

To help our customers solve the challenges of today and tomorrow’s grid, our solutions are 

backed by our S&C experts. These are the men and women with skills and know-how to help 

customers plan and execute the solutions they need – from concept through completion.

S&C provides solutions for customers worldwide. The company has engineering offices and
