The short answer

This page is for buyers who need a resin with documents behind it: a food-contact letter, biocompatibility test data, change notification and lot traceability. Choose the resin for the part first, then the grade whose documents cover your use, because compliance belongs to a named grade, not a resin family. The most common problem is a silent change: a different grade, colorant, regrind source or supplier that the documents never covered.

FDA food-contact grades

Polypropylene, polyethylene, PET, polycarbonate and other families in grades that the producer states comply with the applicable FDA food-contact regulation (for example 21 CFR 177.1520 for polyethylene and polypropylene) for stated food types and conditions of use. They serve packaging, food-processing components, appliance parts and consumer goods. The compliance letter accompanies the material and lists those limits; suitability of the finished article remains the manufacturer’s responsibility.

Medical-grade resins (non-implant)

Materials for device housings, diagnostic components, labware, drug-delivery hardware exteriors and healthcare packaging. We supply medical-grade resins for non-implant applications only. We do not supply materials for implantable, in-body devices. Medical-grade here means resins that the producer designates for healthcare use, typically with biocompatibility test data on the resin, formulation control and change notification. The device maker remains responsible for evaluating the finished device.

What you get with every lot

properties tested to ASTM & ISO methods on the material
Certificate of analysis (COA) with every lot
Grade and compliance documentation suitable for your quality file
Consistent, named grades: no silent substitutions between lots. Any change of grade or source is agreed with you in writing first, because a regulatory letter applies only to the named grade

Common applications

Medical device housings and enclosures
Diagnostic and lab consumables
Food-contact packaging and closures
Food-processing and appliance components
Healthcare packaging

Compliance is grade- and application-specific. Tell us the application and a polymer chemist confirms the right compliant grade and its documentation before you commit.

Which grade to ask for

Ask for the grade by the documents it carries, not by an "FDA" or "medical" label.

Grade type	Use it for	Watch out for
Food-contact grade with a producer FDA letter	Packaging, closures, food-processing and appliance parts	The letter lists food types and use temperatures; hot fill, fatty or alcoholic foods narrow the choice
Producer-designated healthcare grade	Device housings, diagnostic parts, labware, drug-delivery exteriors	Formulation control and change notification add cost over the standard grade
Grade with USP Class VI test data	Specifications that name USP Class VI	A test result for that grade and color as tested; not an evaluation of your device
Grade with ISO 10993 test data	Parts whose risk assessment includes patient or user contact	Resin data supports, but does not replace, the evaluation of the finished device
Gamma- or EtO-tolerant grade	Parts sterilized after molding	Color shift after gamma; compatibility is grade- and cycle-specific
Grade with an EU 10/2011 declaration or Health Canada letter	Food-contact parts sold in Europe or Canada	A U.S. FDA letter does not cover these markets

Typical starting points. Grades vary, so confirm on the data sheet for the exact grade.

Processing notes

Drying. Dry a medical or food-contact grade exactly as you would the standard grade of the same resin; see the resin drying guide. Use clean, dedicated hoppers where you can so dust from other resins does not carry over.
Melt and mold temperature. Stay inside the producer's window. Some healthcare grades carry heat-sensitive stabilizers, and overheating can change color and extractables.
Shrinkage. A compliant grade can shrink differently from your current grade. Treat a switch as a new grade: sample, measure, approve.
Regrind. Use only your own clean regrind of the same grade, and only if your quality plan and customer allow it. Many medical programs allow none. Regrind from outside sources breaks the documentation chain.
Colorants and purging. Colorants, mold releases and anything else left in or on the part need their own documentation. Purge fully between grades.
Most common failure. A documentation break: an unapproved colorant, a substituted grade or mixed lots. Record the lot number of each bag or box on the job traveler.

What to put on the purchase order

The exact grade name, and color if pre-colored, as named on the producer's letter or test report.
The use: food type, temperature and contact time for food contact; contact type, duration and sterilization method for medical parts.
Documents by grade: the producer's FDA letter (citing the 21 CFR section or FCN), and USP Class VI or ISO 10993 test data if your specification names them. Some producers keep a master file with FDA and will issue a letter authorizing a device maker to reference it; ask whether one exists for the grade.
Change notification: ask whether the producer commits to advance notice of formulation, raw material or site changes for the grade, and how much notice it gives.
Lot traceability: a lot number on every bag or box, a COA for every lot, and no mixed lots in one package.
No substitution: no change of grade or source without your written approval.
COA values to check against your incoming specification (melt flow, and color values for pre-colored grades).

When to consider something else

If the part touches food but not patients, see FDA food-contact resin for how the letters work.
If the housing is wiped with hospital disinfectants, see best plastic for medical device housings.
If the part needs repeated steam sterilization, look at PSU and PPSU or PEI.
If your customer asks for RoHS, REACH, Prop 65 or PFAS statements, see resin compliance documents.

Common questions

Is there such a thing as FDA approved plastic?

Not for a resin grade. FDA does not approve individual resin grades. A grade is compliant when its composition meets a food-contact regulation or an effective Food Contact Notification for the intended use, and the producer states that in a letter. Ask for that letter for the exact grade and check the food types and temperatures it covers.

What is the difference between USP Class VI and ISO 10993?

USP Class VI is a set of biological reactivity tests from the U.S. Pharmacopeia, often run on a resin and reported for the grade and color tested. ISO 10993 is a series of standards for the biological evaluation of medical devices, based on a risk assessment of the finished device and how it contacts the body. Resin data under either supports your evaluation; it does not replace it.

Does a medical-grade resin make my device compliant?

No. A healthcare grade gives you a documented, controlled starting material, often with test data and change notification. The device maker still evaluates the finished device, including colorants, processing and sterilization. ResinBridge supplies resins for non-implant applications only.

Can I use surplus or off-grade resin for medical or food-contact parts?

Only if it is the exact compliant grade, traceable to the producer by lot number, and your customer and quality system accept the source. Wide-spec, off-grade and outside regrind usually lack the documentation. A similar grade from another producer needs its own letter and test data.
