Federal Trade Commission (FTC) & National Stamping Act (15 U.S.C. § 291-300)
United States Gold-Filled & Jewelry Regulatory Standards
In the United States, gold-filled jewelry is governed under federal law by the Federal Trade Commission Guides for the Jewelry, Precious Metals, and Pewter Industries (16 CFR Part 23, § 23.3) and the National Gold and Silver Stamping Act (15 U.S.C. §§ 291–300). Under 16 CFR § 23.3, an article may only be described as 'Gold Filled' if the mechanical gold layer comprises at least 1/20th (5%) of the total weight of the article, with a minimum fineness of 10 Karat. If the gold layer comprises 1/40th or 1/10th, the exact fraction must precede the term (e.g., '1/40 14K Gold Filled'). Electroplating cannot be marketed as gold-filled, regardless of plating thickness.

Terminology Guidelines for United States
Avoid border seizures and consumer regulatory enforcement by understanding exact statutory terminology.
| Term | Legal Classification | Statutory Meaning & Restriction |
|---|---|---|
| Gold Filled (GF) | Legally Defined | Mechanically bonded gold layer comprising at least 1/20th total weight, minimum 10K fineness. |
| Rolled Gold Plate (RGP) | Legally Defined | Mechanically bonded gold layer comprising less than 1/20th total weight (typically 1/30th to 1/40th), preceded by fraction. |
| Gold Vermeil | Legally Defined (16 CFR § 23.4) | Sterling silver (925) base coated with minimum 10K gold at a thickness of no less than 2.5 microns (100 millionths inch). |
| Gold Overlay | Legally Defined | Synonymous with Rolled Gold Plate under 16 CFR § 23.3; requires explicit fraction if under 1/20th. |
| Gold Bonded / Solid Gold Filled | Deceptive / Prohibited | Misleading terms that imply solid gold construction or violate standardized nomenclature under 16 CFR § 23.3. |
Composition Analysis
Gold Filled vs Alternative Materials in United States
How gold-filled compares against Vermeil, plating, and solid gold under local commercial norms.
| Material | Core Alloy | Gold Content | Bonding Method | Lifespan | Marking Standard |
|---|---|---|---|---|---|
| 14K Gold Filled (1/20) | Jeweler's Brass (CDA 220 / CuZn10) | 5.0% by total weight (14K fineness) | Heat & Pressure Solid-State Cladding | 10–30 years of regular wear without flaking | 1/20 14K GF + Registered Trademark |
| Gold Vermeil | Sterling Silver (92.5% Ag) | ≥ 2.5 microns electroplated gold (≥10K) | Galvanic Electroplating onto Sterling Silver | 3–7 years depending on friction | 925 + Vermeil or 925 V |
| Heavy Gold Electroplate | Brass, Bronze, or Copper alloy | ≥ 2.5 microns gold (any base) | Galvanic Electroplating | 2–5 years of wear | H.G.E. or Heavy Gold Electroplate |
| Standard Flash Plated | Brass, Zinc, or Pot Metal | 0.05 to 0.25 microns | Flash Immersion Plating | Few weeks to several months | Gold Plated / GP (No Karat guarantee) |
| Solid 14K Gold | None (Uniform alloy) | 58.33% pure gold alloyed throughout | Direct casting and fabrication | Indefinite / Heirloom | 14K or 585 + Maker's Mark |
✓ Permissible Marketing Claims
Lawful commercial descriptions under FTC Jewelry Guides (16 CFR Part 23) & 15 U.S.C. §§ 294-300:
- “1/20 14K Gold Filled” (when product verified at 5.0% 14K gold by weight)
- “Tarnish-resistant mechanical gold cladding”
- “Hypoallergenic exterior layer composed of solid 14 Karat gold”
- “Water-resistant under daily wear conditions”
✕ Prohibited & Deceptive Claims
Violations that trigger consumer agency investigation or customs seizure:
- “Solid Gold” or “Real Gold” without explicit disclosure of the non-precious core
- “Gold Filled” for electroplated, dip-coated, or PVD vapor-deposited brass
- Stamping “14K GF” without the fractional ratio “1/20”
- Applying a quality stamp without an accompanying registered trademark (violates 15 U.S.C. § 297)

Frequently Answered Questions
Common Questions on United States Jewelry Compliance
Can I stamp '14K GF' on my jewelry without the fraction in the United States?
No. The FTC Guides (16 CFR § 23.3) require that the term 'Gold Filled' be preceded by the proportional weight fraction, e.g., '1/20 14K GF'. Omitting the fraction is considered deceptive trade practice.
Do I need a registered trademark next to the karat stamp in the US?
Yes. Under the National Stamping Act (15 U.S.C. § 297), if an item is stamped with any quality mark, it must be accompanied by an official registered trademark or the legal name of the brand.
Is electroplating 2.5 microns of gold over brass considered gold-filled?
No. In the US, gold-filled specifically denotes a mechanical bonding process. Gold over brass via electrodeposition is 'Heavy Gold Electroplate' (H.G.E.), never gold-filled.
