ITAR Registered
ITAR Registered
STC was certified ITAR registered starting July 2007 and has been most recently re-registered June 2023.
The International Traffic in Arms Regulations (ITAR) is a set of United States government regulations that control the permanent and temporary export and import of defense-related articles and services.

The ITAR’s purpose is to protect U.S national security and advance U.S foreign policy goals. The Department of State Directorate of Defense Trade Controls (DDTC) is responsible for the interpretation and enforcement of ITAR.
ITAR ensures that information and materials regarding defense and military related technologies are only shared with United States individuals or foreign (non-US) nationals granted special authorization by the Department of State.
United States organizations and/or individuals face severe fines if they are found to have provided access to ITAR regulated defense articles, services or information to unauthorized foreign entities.
ITAR is available from the Government Printing Office (GPO) as an e-document or as part of the annual hard copy publication of the Code of Federal Regulations (CFR) which includes all amendments made to the ITAR since the last annual publication. You can find out more about ITAR by visiting the U.S. Department of State website.

Understanding REACH
REACH is a regulation of the European Union, adopted to improve the protection of human health and the environment from the risks that can be posed by chemicals, while enhancing the competitiveness of the EU chemicals industry. It also promotes alternative methods for the hazard assessment of substances in order to reduce the number of tests on animals.
REACH places the burden of proof on companies. To comply with the regulation, companies must identify and manage the risks linked to the substances they manufacture and market in the EU.
REACH stands for Registration, Evaluation, Authorisation and Restriction of Chemicals. It entered into force on 1 June 2007.
RoHS Compliant
STC RoHS Compliance Statement
Superior Technical Ceramics makes no stand-alone electronic or electrical products, but is proud to be a subcontractor of ceramics used in electronic and electrical products. STC has been asked by numerous customers to confirm that our ceramics are RoHs Compliant
After a complete review of our materials used in our parts and the manufacturing process, we can advise you, our customers, that Superior Technical Ceramics is RoHS 3 compliant.

RoHS stands for Restriction of Hazardous Substances, and impacts the entire electronics industry and many electrical products as well. The original RoHS, also known as Directive 2002/95/EC, originated in the European Union in 2002 and restricts the use of six hazardous materials found in electrical and electronic products. All applicable products in the EU market since July 1, 2006 must pass RoHS compliance.
Directive 2011/65/EU was published in 2011 by the EU, which is known as RoHS-Recast or RoHS 2. RoHS 2 includes a CE-marking directive, with RoHS compliance now being required for CE marking of products. RoHS 2 also added Categories 8 and 9, and has additional compliance recordkeeping requirements.
Directive 2015/863 is known as RoHS 3. RoHS 3 adds four additional restricted substances (phthalates) to the list of six.
EU RoHS specifies maximum levels for the following 10 restricted substances. The first six applied to the original RoHS while the last four were added under RoHS 3.
- Cadmium (Cd): < 100 ppm
- Lead (Pb): < 1000 ppm
- Mercury (Hg): < 1000 ppm
- Hexavalent Chromium: (Cr VI) < 1000 ppm
- Polybrominated Biphenyls (PBB): < 1000 ppm
- Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm
- Bis(2-Ethylhexyl) phthalate (DEHP): < 1000 ppm
- Benzyl butyl phthalate (BBP): < 1000 ppm
- Dibutyl phthalate (DBP): < 1000 ppm
- Diisobutyl phthalate (DIBP): < 1000 ppm
