What Does Implant-Grade Actually Mean?
Share
One of the biggest misconceptions in body piercing is that if a piece of jewelry is labeled "titanium," it's automatically suitable for a new piercing.
Unfortunately, that's not always the case.
The word titanium simply describes the metal. It doesn't tell you whether the material has been manufactured, tested, or certified for use inside the human body.
Grade 23 vs. ASTM F136
You may see jewelry advertised as Grade 23 titanium (Ti-6Al-4V ELI).
Grade 23 describes the alloy's chemical composition—often referred to as the "recipe" for the metal. While it's the same alloy used in implant-grade titanium, the Grade 23 designation alone doesn't verify that the material has been manufactured and certified to medical implant standards.
For body jewelry, what really matters is ASTM F136 certification.
ASTM F136 is a recognized medical material specification for implant applications. Manufacturers producing jewelry to this standard verify that the material meets strict requirements for chemistry, mechanical properties, and quality. Reputable companies can also provide mill certificates and material traceability documenting that the titanium meets the ASTM F136 specification.
In other words:
- Grade 23 tells you what alloy it is.
- ASTM F136 tells you that the material has been verified to meet a recognized implant standard.
That's an important distinction.
| Generic "Titanium" | ASTM F136 Implant-Grade Titanium |
|---|---|
| May only identify the metal | Meets a recognized implant material specification |
| Certification may not be documented | Supported by material documentation and traceability |
| Quality varies by manufacturer | Manufactured to strict medical material standards |
| Not all body jewelry qualifies | Commonly used by reputable professional body jewelry manufacturers |
| Limited information available to consumers | Material verification can be supported with mill certificates |
Why We Care
When you're healing a new piercing, your jewelry isn't just an accessory—it's a medical device that remains inside your body while tissue heals around it.
That's why we choose jewelry manufactured from ASTM F136 implant-grade titanium from trusted body jewelry companies that maintain documentation, quality control, and traceability.
Because when it comes to something that's staying in your body for months—or even years—we believe verified quality matters.
Material Is Only Half the Story
Even the best metal can't compensate for poor craftsmanship.
Professional body jewelry should also feature:
- Mirror-polished finishes
- Accurate threading or threadless construction
- Proper gemstone settings
- Precise sizing
- Consistent manufacturing quality
These details improve comfort, reduce irritation, and contribute to successful healing.
The Essential Ink Standard
At Essential Ink, we don't purchase jewelry based solely on marketing claims like "titanium." We source jewelry from trusted manufacturers that provide documentation supporting the materials they use, including ASTM F136 implant-grade titanium where applicable. We believe quality should be verifiable—not just advertised.
Why You'll Hear Us Talk About Jewelry So Much
People often assume the jewelry is just decoration.
In reality, it's a medical device that remains inside your body while you heal.
That's why we spend so much time discussing materials, manufacturers, sizing, and jewelry styles during your appointment.
Our goal isn't to sell you the most expensive piece—it's to recommend jewelry that gives your piercing the best opportunity to heal comfortably while reflecting your personal style.

FAQs
What does implant-grade titanium mean?
Implant-grade titanium refers to titanium that meets recognized medical material standards, such as ASTM F136, for use in implants. These standards verify the material's chemistry, mechanical properties, and quality for long-term use in the body.
Is Grade 23 titanium the same as ASTM F136?
Not exactly. Grade 23 (Ti-6Al-4V ELI) describes the alloy itself, while ASTM F136 is the medical material specification that verifies the alloy meets specific standards for implant applications. The alloy may be the same, but ASTM F136 certification provides documented verification through testing and traceability.
What are mill certificates?
Mill certificates are documents provided by the manufacturer that verify the material's composition and confirm it meets the required specification. They provide traceability and help verify that the jewelry is made from the material it claims to be.
Is all titanium jewelry implant-grade?
No. A piece of jewelry can be labeled "titanium" without meeting ASTM F136 standards. That's why it's important to purchase jewelry from reputable manufacturers that provide documentation and quality assurance.
Why does Essential Ink use ASTM F136 titanium?
We believe quality should be verifiable—not just advertised. That's why we prioritize jewelry made from ASTM F136 implant-grade titanium from trusted manufacturers who maintain documentation, traceability, and high manufacturing standards.
