Send your Samples for Biobased Content Testing

Contact us anytime. We respond to inquiries promptly during business hours (8 AM-5 PM EST, Monday-Friday).

Beta Analytic is a tracer-free laboratory. Beta Analytic clients who submit samples with artificial/labeled/tracer Carbon-14 will be liable for the damage and clean-up costs as per our Terms and Conditions of Services.

 Step 1

Prepare the recommended quantity

Materials NOT SUITABLE for garbage disposal – Please contact the lab for discussion prior to submittal.

Materials suitable for garbage disposal:

– Solids

  • MAXIMUM: 0.1 to 1 oz (2.8 to 25 grams) – retail piece or applicable sub-sample
  • Plastic Pellets – 5 to 10 grams ONLY

Please contact us before sending your samples. The lab will need instructions on which component to analyze especially for products with multi-color parts.

For the analysis to be meaningful, the carbon analyzed must be representative of the whole product. The result itself only applies to the analyzed materials. Heterogenous materials should be discussed with the laboratory prior to analysis to ensure the analyzed material is representative of the whole product.

– Liquids

  • Chemicals, solvents, lubricants, oils, liquids with high petrochemical content – 1 mL (1 cc) per sample
  • Liquids with no volatile organic compounds (VOCs) – 10 mL (10 cc) per sample

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

Please use plastic or glass vials as sample containers. 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.

NOTE: If the sample contains VOCs, the vial should be full (no head space). 

Step 2

Fill out all necessary documents

Beta Online Data Sheet

The lab does not need information that you feel may breach the confidentiality of your product.

Presence of volatile components in the samples that may be lost during handling

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.

Presence of any carbonates in the material to be analyzed

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.

Step 3

Send samples and documents to a Beta Analytic office

When sending directly to Miami, please use this label for customs declaration: “Carbon NCM Number 2803.00 – for scientific study – to be destroyed entirely during the analysis – no commercial value.”
Customs and carriage value: 1 USD
Harmonized Tariff Number (HS code) – 280300

Please make sure that the shipping company you choose takes full responsibility to clear the package with US customs when sending samples directly to the US. You are welcome to contact us for shipping advice.

Note: Beta is not responsible for the clearance or transportation costs of international shipments not sent through one of our forwarding offices. Shipments arranged through a freight forwarder must be sent under DDP terms. The shipper is responsible for handling the administrative requirements to release the shipment.


Analyses are started immediately upon receipt of samples to best ensure we meet our promised delivery. This means that charges are also incurred immediately upon receipt of samples. Change orders are welcome, but please be aware that partial or full charges will apply based on how much work has been completed by the time of the change request.

It is very important to inform us before shipping hazardous samples so we can give you the correct instructions and shipping address. Samples need to be shipped to the US if they are designated as hazardous by the International Air Transport Association (IATA). Hazardous substances with IATA Excepted Quantity Codes E1, E2, E4 or E5 and those in Packing Groups II and III qualify for De Minim​i​s shipping. To ship as De Minimis​ to our Miami office​, the sample volume must not exceed 1 mL and the packaging must follow the guidelines in the Dangerous Goods Regulations, being sufficiently absorbent in case of leakage and sturdy enough to prevent breakage. No special labelling is required for De Minimis shipping. For detailed information, please consult the IATA Dangerous Goods Regulations.

  • If you are doing R&D or product development, generally one measurement is fine.
  • If you are submitting samples for the USDA BioPreferred program, please read this page carefully.

Submitting samples for other purposes? We are available for consultation.

Our laboratory does not have the facilities for handling or disposing certain hazardous materials, and as such we cannot accept carcinogenic materials 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 prior to sending the samples to discuss the appropriate amount to send.

Chemicals must include SDS/MSDS. We must have a copy on file. Please include it in the package to avoid delays. If we already have the latest version of an SDS on file for your product, please indicate so on your submittal form.

A Beta representative will contact you to confirm the safe arrival of your samples in MIAMI and to quote you a delivery date for the results. Our quoted turnaround time starts following the day of receipt at the Miami laboratory excluding weekends.
