DNA Shipping Instructions

Sending DNA to USA

Sample Preparation & QC:

Verify that each tube contains a minimum volume of 50 µL of extracted DNA. Record and share by email the input weight used for each extraction (0.15–0.20 g per sample).

Provide Metadata:

Fill out the metadata sheet (the Excel sheet will be emailed to you.) Minimum required fields:

• Sample reference (Any label/numbering system that you use internally to differentiate your samples)
• Date collected
• Crop type
• Coordinates (latitude and longitude, easy to obtain on Google Maps by dropping a pin on the block on satellite view)

Print All Documents (Reach out to your BMK rep for the DNA Import Letter):

• Metadata Excel sheet x 2

• Commercial invoice

• Completed DNA Import Letter

Packaging Instructions:

Once you have collected the samples and filled out the metadata sheet and the DNA Import Letter, assemble your samples for safe export as follows:

• Place each DNA sample inside a coded vial

• Consolidate all individual samples in a larger waterproof sealed bag (mandatory).

• Failure to consolidate the samples will result in US Customs holding the shipment.

• Add some cushion materials and an ice pack (optional but recommended)

Shipping Instructions:

Once the samples are safely packed, include the following documentations in the package as follows:

Affixed to the outside of the package:

• 1st printed copy of Metadata excel sheet (in a pouch)

• Commercial Invoice (provided by courier)

• DNA Import Letter

Inside the package:

• Samples in tubes or sealed bags

• 2nd printed copy of Metadata excel sheet

Shipping Label Instructions:

• Clearly identify what is being shipped (ex. 10 DNA samples for Analysis, Not for Resale)

• Do not ship DNA and soil together as Customs will hold the package

• When prompted to add a Tariff/HTS Code use: 2934.99

• When generating the Commercial Invoice, please label the samples as “No Commercial Value”

• Ensure all duties, taxes, and fees are delegated to the shipper and not the receiver
