SVHC Substances Not Detected

Substances of Very High Concern (SVHC) are chemicals subject to regulation under EU REACH regulations. All 235 substances listed were not detected in Ocean Tech's zinc weights, proving complete eco-friendliness.

* SVHC testing means that an accredited laboratory systematically checks whether a product contains any of the 235 hazardous substances listed by the EU — such as carcinogens, mutagens, and reproductive toxins. Passing this test is the highest international standard of chemical safety, and it directly assures fishers, consumers, and regulators that Ocean Tech's zinc weights pose zero chemical risk to people or the marine ecosystem.
