[Shipping Instructions](https://help.momentum-transfer.com/shipping-instructions?hsLang=en) # How to Ship Your Samples to Us – Mining Customers This article explains how to prepare, package and ship your samples to us. Please read it carefully before sending your samples, and don’t hesitate to contact us if you need any assistance.   **Please note:** Before you ship your samples, we create your measurement request in our data portal for you. You can find out how this works and how to access your request here.  --- ### Sample form and pre-preparation **Be sure that your samples are compatible with our measurements.** Please send your mining samples as a powder, e.g. crushed rock, ore, concentrate or tailings, with a **maximum particle size of 1 mm**. You do not need to grind your samples any finer, as we prepare them by mechanical milling in our lab. If you would like to send your samples in a different form, e.g. as a solid piece or as a suspension, **please send us an email to** [team@momentum-transfer.com](mailto:team@momentum-transfer.com) **to discuss.** #### Samples not suitable for our services - single crystal samples - samples with significant texture or preferred orientation - ultra-thin films and films on crystalline substrates - samples that need special environments or complex supports ##### **Please do not send more than 10 g per sample and at minima 5 g.** --- ### Containers and labeling **Use one of the recommended types of containers.** **![](https://help.momentum-transfer.com/hs-fs/hubfs/image-png-Nov-13-2026-10-12-19-1584-AM.png?width=430&height=361&name=image-png-Nov-13-2026-10-12-19-1584-AM.png)**                           *Example containers.*  - **transparent glass or plastic** containers with a secure screw cap (e.g. glass vials with a volume of approx. 10 ml) - choose a container large enough to hold the full sample amount of **5 g - 10 g** without overfilling - use **printed labels** with the **sample IDs** exactly as stated in your sample list - contents should be visible (i.e. labels should not cover the whole outer surface) Please use printed labels so samples can be easily identified. We admit that even our own handwriting is often difficult to read. If you cannot print, please write legibly. --- ### Air-sensitive samples For samples that require handling in a glovebox, the container should be able to withstand medium vacuum conditions during the purging of the antechamber. See further details [here](https://help.momentum-transfer.com/how-we-handle-air-sensitive-samples?hsLang=en). --- ### Packaging Please use stiff packaging with plenty of padding around the containers, so that they cannot shuffle around, break or open during transit. Make sure the screw caps are tightly closed, and use additional containment, e.g. a sealed plastic bag, in the unfortunate case of sample leakage. --- ### Documentation So that we can easily identify your samples, please include your sample list together with a description of any special handling requests, if necessary, with your samples. --- ### Shipping address Please send your samples to the following address: **Momentum Transfer GmbH** Elly-See-Str. 1 22547 Hamburg Germany [thomas.unger@momentum-transfer.com](mailto:thomas.unger@momentum-transfer.com) Please do not ship samples to us before we have created your measurement request and sent you your invitation to the data portal. --- ### Choosing a shipping company We strongly recommend using international logistics companies, such as **DHL, FedEx or UPS**, instead of national postal services. In the past, shipments sent via national postal services have been returned to the sender without us being informed, which caused significant delays. **Users are responsible for arranging the shipment of their samples in compliance with all relevant regulations.** --- ### Share your tracking information with us As soon as you have shipped your samples, please send us the **tracking link** of your shipment by email to [team@momentum-transfer.com](mailto:team@momentum-transfer.com). This allows us to track your shipment and to step in quickly if any problems arise, for example with customs. --- ### Shipping from outside the European Union If you send the samples from a country outside the European Union, customs services may ask us for additional documents, specifically a pro forma invoice corresponding to the contents of your shipment. Please prepare a pro forma invoice and attach it to the outside of your package. Please also send us a copy via email to ensure a smooth processing of the shipment. You can download an editable template of the pro forma invoice [here](https://help.momentum-transfer.com/hubfs/Proforma_Invoice_Mining.docx?hsLang=en).  - [Our Measurement Services](https://help.momentum-transfer.com/our-measurement-services?hsLang=en#main-content) - [X-ray Powder Diffraction](https://help.momentum-transfer.com/our-measurement-services?hsLang=en#x-ray-powder-diffraction) - [Total Scattering – Pair Distribution Function](https://help.momentum-transfer.com/our-measurement-services?hsLang=en#total-scattering-pair-distribution-function) - [Small-Angle Scattering](https://help.momentum-transfer.com/our-measurement-services?hsLang=en#small-angle-scattering) - [Using Our Data Portal](https://help.momentum-transfer.com/using-our-data-portal?hsLang=en#main-content) - [How to Set Up a Billing Account](https://help.momentum-transfer.com/using-our-data-portal?hsLang=en#how-to-set-up-a-billing-account) - [How to Review and Edit Billing Details](https://help.momentum-transfer.com/using-our-data-portal?hsLang=en#how-to-review-and-edit-billing-details) - [Data Processing & Analysis](https://help.momentum-transfer.com/data-processing-analysis?hsLang=en) - [Shipping Instructions](https://help.momentum-transfer.com/shipping-instructions?hsLang=en) - [FAQs](https://help.momentum-transfer.com/faqs?hsLang=en#main-content) - [General Information](https://help.momentum-transfer.com/faqs?hsLang=en#general-information) - [Momentum Transfer Data Portal](https://help.momentum-transfer.com/faqs?hsLang=en#momentum-transfer-data-portal) - [Preparing & Shipping Samples](https://help.momentum-transfer.com/faqs?hsLang=en#preparing-shipping-samples) - [Data & Publication](https://help.momentum-transfer.com/faqs?hsLang=en#data-publication) - [Measurement Details](https://help.momentum-transfer.com/faqs?hsLang=en#measurement-details) - [Publications](https://help.momentum-transfer.com/publications?hsLang=en#main-content) - [2025](https://help.momentum-transfer.com/publications?hsLang=en#2025) - [2024](https://help.momentum-transfer.com/publications?hsLang=en#2024) - [Policies & Legal](https://help.momentum-transfer.com/policies-legal?hsLang=en) - [Imprint](https://momentum-transfer.com/imprint) - [Privacy Policy](https://momentum-transfer.com/data-protection) - [Terms & Conditions](https://momentum-transfer.com/terms-conditions) [![MT Logo](https://help.momentum-transfer.com/hs-fs/hubfs/mt_logo_inverted.png?width=100&height=100&name=mt_logo_inverted.png "MT Logo")](https://momentum-transfer.com/) *Radically better X-ray data*   ``` Question?
