Monofilament Sufix Advance
Fishing line; no known PFAS treatment, but brand silent on composition.
Sufix Advance is a nylon monofilament with no disclosed PFAS risk. Typical fishing line material is lower concern unless coated or treated, which is not advertised here.

The full breakdown
What it's made of and why it matters
Sufix Advance is a nylon monofilament, a single continuous strand of extruded polyamide polymer. Nylon monofilament does not release harmful monomers or plasticizers into water or skin during normal use because it is a cross-linked solid polymer, not a flexible plastic with additives. The material is inert in aquatic environments and does not biodegrade, which is an environmental concern but not a direct consumer safety hazard.
The brand's record and disclosure
Sufix (owned by Rapala VMC) does not publicly disclose detailed ingredient composition or third-party safety certifications for its fishing lines. The brand has no documented recalls or safety controversies tied to this product line. Lack of transparency on PFAS treatment is notable but consistent with industry-wide silence on this issue in fishing tackle.
How it compares in its category
Monofilament fishing lines are broadly similar regardless of brand; Sufix Advance is mid-market positioned. Braided lines (often polyethylene) and fluorocarbon alternatives pose no additional established hazards compared to monofilament. The main differentiation is durability and cost, not safety profile.
If you buy it
Store line out of direct sunlight to slow UV degradation, which can embrittle nylon over 1-2 years. There is no heating or food-contact scenario with fishing line. Dispose of spent line in regular waste; do not leave in freshwater or ocean environments. Replace when line shows visible cracks, cloudiness, or loss of strength.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Nylon polymer degradation and microplastic release
Monofilament nylon can fragment into microplastics when abraded on rocks, reels, or guides over extended use. No public data quantifies release rates from this specific product, but nylon's brittleness increases with UV exposure and age.
Heavy metals in dye or UV stabilizers
Nylon monofilament is not typically dyed with azo dyes or heavy-metal pigments. Sufix Advance line is commonly available in clear or low-color variants that require minimal colorant. No reports of lead, cadmium, or chromium contamination in this product.
Flame retardants or antimony additives
Fishing line is not treated with flame retardants or antimony compounds. Nylon's inherent flame properties (slow burning, melts) make such additives unnecessary and uneconomical.
Formaldehyde or other volatile organic compounds
Solid monofilament nylon does not release formaldehyde or VOCs during storage or use. No off-gassing hazard is documented for this product category.
Skin irritation or sensitization from material contact
Nylon monofilament is inert and does not sensitize skin on brief contact. Abrasion from rough edges or knots can cause mechanical irritation, but this is not a chemical hazard specific to Sufix Advance.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 60% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
