Nickel and cadmium, stated honestly
Updated

Nickel
Nickel is a frequent contact allergen in jewelry and there is no federal United States restriction on nickel release from it. The European Union restricts nickel release in articles intended for prolonged skin contact under its own chemicals regulation, which is why nickel free claims are common on products made for both markets.
So what does a nickel free claim mean here
Whatever the seller means by it, which is the problem. With no federal definition, the claim is a marketing representation and sits under general truth in advertising principles rather than a numeric standard. If you make the claim, be able to say what test and what threshold you mean by it.
Cadmium
The CPSIA lead provisions are about lead. There is no general federal cadmium content limit for children’s jewelry equivalent to the 100 ppm lead limit. ASTM F2923, the consumer product safety specification for children’s jewelry, is a voluntary consensus standard that addresses cadmium among other hazards, and a number of states have legislated in this area.
We have not surveyed the state law
That is a deliberate omission, not an oversight. State jewelry metals statutes differ in scope, in the metals covered and in the age ranges they apply to, and a summary written without checking each one would be worse than no summary. Check the states you sell into.
Why stating the absence is useful
Because the two most expensive mistakes in this category are assuming a federal rule exists and assuming nothing applies. The first leads to testing you did not need, the second to a voluntary standard your retailer requires contractually and you have not met.
What retailers ask for in practice
Large retailers frequently require conformance to ASTM F2923 by contract, independent of federal law. If your route to market is through a chain, their vendor requirements may be a stricter and earlier constraint than anything in the CFR.
