USDA BioPreferred Voluntary Labeling Process

Before submitting your samples, please consult directly with the USDA. Results obtained in advance of the signed agreement and acceptance into the program will not be accepted by ASTM or the USDA. Make sure your Biobased Participant Agreement with ASTM has been signed and accepted.

All information about the label application process is found in .

Submission Guide

 Step 1

Fill out all documents first before submitting your samples to the lab.

The lab needs the following:
– Beta Analytic Data Sheet (online form), please check “Yes” for the USDA Voluntary Label
USDA Application Number and Documentation of Sample Selection, Shipping, and Disposal by Manufacturer/Vendor form (signed) 

Step 2

Prepare recommended sample sizes

Materials suitable for garbage disposal Maximum
Liquids Retail container or applicable sub-sample 1 fl oz (30 cc)
Solids Retail piece or applicable sub-sample 1 oz (25 grams)
Materials requiring special disposal Please contact the lab for discussion.

IMPORTANT: Beta Analytic can only receive chemicals, solvents, and fuels in very small quantities – not exceeding 0.3 cc (300 microliters).

Sampling – Unless otherwise instructed, we will subsample the submitted material in a quantity reasonable for the analytical method. If there are any special instructions to ensure the subsample best represents the client’s interests, please discuss with the laboratory prior to analysis. Since the laboratory cannot be experts in all manufacturing processes and products, the responsibility for analysis of a representative subsample lies with the client/submitter. For details, see Sub-sampling Reminders below.

Recommended Container for Liquids – 1 mL glass micro-sample vial with a crimp top that has a Teflon-lined septum. The vial should only be ¼ – ½ full.

Recommended sample containers for liquids

Make sure the vials have snap caps or any tight closure that will prevent leakage. You can also use vials found at this site. Wrap the vials properly to prevent breakage during shipment.

Please make sure the vials have chemically non-reactive seals, e.g. made of a silicone disk with one or two teflon faces. If you use low-volume screw top vials like the amber one above, make sure they have a non-reactive cap liner made from silicone and teflon or some other chemically non-reactive material. Do not use vials that have caps lined with a piece of cardboard with an Aluminum-foil face on one side. The cardboard side is glued to the cap. These are not suitable for volatile liquids as the vapors can dissolve the glue and contaminate the sample during shipment.

Step 3

Send samples and necessary documents to Miami

Please email us the courier and tracking number.

Shipping address:
Beta Analytic Inc.
4985 SW 74th Court
Miami, Florida 33155

All hazardous materials (containing combustible elements) must adhere to International Air Transport Association (IATA) regulations; details can be found in the Fedex Packaging Dangerous Goods section.

Samples Received in Miami

A Beta representative will contact you to confirm the safe arrival of your samples and to quote you a delivery date for the results.

Sub-sampling Reminders

Your application with USDA will ask you to list your product as either a retail product or an intermediate product. “Retail” is defined as a product that is purchased directly by the consumer or is packaging used “as-is” to contain a product purchased by the consumer. “Intermediate” is a raw material which is sold, then modified or used in making a “retail” which is then purchased by the consumer.

If you have listed your material on the USDA application as an intermediate product, it is OK to sub-sample and deliver in any packaging appropriate for the material. Beta Analytic will take a picture once the sample is received in the laboratory.

If you have listed your material on the USDA application as a retail product, USDA would like you to send a sample in its retail packaging (usually the smallest available is requested by the laboratory). The laboratory is required to take a picture of this as third-party validation of what was analyzed (i.e. the result was obtained on material taken from the same container shown in the picture). You cannot sub-sample and take a picture yourself for a product applied for as a retail product. You must send the product in its final consumer packaging. There is no self-declaration option for retail product sub-sampling.

Beta Analytic can receive a maximum of 25 grams or 25 mL per sample. If your product is bigger, please contact ASTM to obtain approval for sub-sampling before it is submitted for testing.

The client should ensure that the products to be sent can be safely disposed of in the state of Florida. For example, bleach is okay, but certain solvents are not okay. If there is a doubt, please consult the laboratory before submitting the sample. If you would like to sub-sample a retail product before submitting it to the laboratory, please consult the USDA.

After you have reached the stage of signing a contract with ASTM (the Participant Agreement), ASTM will instruct you to contact Beta to discuss the details of the analysis (including appropriate quantity to send and where to send it).

Beta Analytic Laboratory Reminders:

– Heterogeneity issues

Results will only be representative of the actual material analyzed. Heterogenous materials should be discussed with the laboratory prior to analysis to ensure the sample is representative of the whole product.

– Presence of Carbonates

ASTM D6866 requires carbonate components to be excluded from the biobased content result. Special procedures are required for materials containing carbonates. The lab needs to know if there are carbonates within your product and discussion must be pursued prior to analysis to ensure accurate results.

– Volatile Organic Compounds (VOC) and other Volatile Components

If you want to analyze the VOCs in your product, please consult us before shipping the sample. We can only analyze gases submitted as CO2 (either pure or in air mixtures).

Accurate analysis requires recovery of all available carbon within the product. If a biobased component is volatile and a petroleum component is not, the measured biobased content for the product will be too low if the volatiles are not recovered in the same proportion as the non-volatile petroleum components. Special procedures are readily applied to handle such samples but the laboratory needs to be aware of the need, e.g. evaporative hand sanitizers. Note that it is the submitter’s sole responsibility to provide the laboratory with this information.

– Carcinogenic Materials

Please take note that we do not have the facilities for handling or disposing of certain hazardous materials. As such, we cannot accept carcinogenic substances or materials requiring special disposal procedures. In the case of highly flammable or certain toxic materials (e.g. phenols), we can accept very small quantities such that disposal is not an issue. However, please contact us in advance of sending the samples to discuss on the appropriate amount to send.
