We are committed to excellence in all aspects of our business

We are committed to excellence in all aspects of our business, including ethical and responsible conduct in our operations, respect for all the individuals we employ and serve, as well as respect for the environment. We expect our suppliers to share the same commitments and encourage our suppliers to meet or exceed our quality standards. We sometimes partner with our suppliers through guidance and problem-solving of manufacturing processes to produce specialized parts. We continually promote performance excellence across all internal and external operational disciplines.


Howell Instruments values the relationships we foster with our Suppliers. The Supplier’s contribution to our supply chain is important in producing a quality product that meets our customer needs and expectations. When Howell extends a purchase order to a Supplier, we are also extending an offer to accept the Supplier’s commitment to provide us with product or component(s) that meet our specifications, requirements, and quality standards. The Supplier quality and delivery requirements are outlined in the Supplier Terms and Conditions document.


Howell Instrument Suppliers and their employees should be aware of their contribution to our product or service conformance by ensuring the specifications and requirements as defined in the purchase order and associated documents are met. This conformance also extends to product safety where all items purchased on a Howell Instruments purchase order shall meet all applicable safety laws, codes (local, national, and international), and directives in accordance with AS9100 and AS9110. Our Suppliers and their employees must also be committed to high standards of ethics and business conduct in accordance with all applicable laws and regulations (ie. corruption, bribery, extortion, human rights).

We thank you for your cooperation and commitment to work with us in order to ensure that Howell Instruments can deliver a quality product as promised to our customers.
