We fulfil orders directly from our sites in the UK and the Netherlands. This keeps our prices low and helps us to provide first-class customer support. Because of this, we are unable to recommend agencies or distributors in most countries. Please contact us if you are unable to purchase from us directly for any reason.

For customers in China who are unable to purchase from us directly, we work with the following select third party distributors:

• Shenzhen Zeren Tech.
• CIF (Beijing) Tech Co., Ltd.
• Mycro Technologies Company Limited

Yes, with very few exceptions, we ship to your country! We can ship anywhere except where trade/customs restrictions apply (including but not limited to Russia, Belarus, Iran, and North Korea). We have customers in over 100 countries around the world including all the countries listed above and more.

Please contact us for advice if you are unsure whether we will be able to ship to your country or if your country is not supported by our online checkout. In some cases customs restrictions may apply.

Worldwide shipping via freight forwarder or other methods is available for a wide variety of countries.

Orders to the EU/EEC may be processed and dispatched by Ossila BV, which is based in Leiden BioScience Park in the Netherlands. All other orders will be dispatched from our main office and manufacturing centre in Sheffield, UK. We aim to ship all in-stock items within one working day.

Customers in the UK, EU, and Canada pay no import duties and charges. For customers elsewhere in the world, import duties or taxes may apply at customs. Please contact us if you are unsure what costs you may be responsible for.

Occasionally, customs may request extra information or subject your order to a more thorough inspection. As a result, some items may be held at customs for longer than normal. Our team work hard to provide all the necessary information as soon as possible so that your parcel can continue its journey and reach you as quickly as possible.

If you are based in the US and your order contains a material, US customs may require you to complete a Toxic Substance Control Act (TSCA) Certification. To save you time, we can complete this on your behalf, but we need your consent to do so. You can give this at checkout or over email when placing your order. If you would rather check the TSCA form over yourself, we will supply you with a partially completed document. In this case, all you will need to do is fill in your company details and send it back to us so that we can forward it on to the courier.

We aim to provide the best materials from the best suppliers for organic electronics. However, patent issues sometimes prevent us from being able to provide certain materials to certain geographical regions. For example, we are unable to sell TIPS-Pentacene to customers in the US.

We will contact you if your order is affected by export controls.

Orders to the EU or EEC placed by customers with an EU billing address are processed and fulfilled by Ossila BV, but depending on stock levels, in some cases your order may still be sent directly from our main office in Sheffield, UK. To facilitate this, if you are in the EU or EEC, your data (such as your name and delivery address) will be shared between Ossila and Ossila BV. Our privacy policy provides more information.

For all other locations, your order will be processed and fulfilled by Ossila Ltd

By default, orders to the EU or EEC placed by customers with an EU billing address are processed and fulfilled by Ossila BV. Please let us know if you would prefer that your order is handled solely by Ossila Ltd. We are happy to facilitate this, but customs fees may apply, as your order will be shipped Delivered at Place (DAP).

For the best service, we recommend placing your order with Ossila BV. Orders placed with Ossila BV are covered by our EU delivery guarantee.

Ossila BV is based in the Netherlands, so we can ship to our customers in Europe without any customs issues. For logistical reasons, some orders are sent directly from the UK. We closely monitor these shipments. If there are any issues, we will deal with it in a timely manner to ensure that your order still reaches you as quickly as possible.

Since Ossila BV is based on the Netherlands, no order fulfilled by Ossila BV will attract any import duties or charges. As a gesture of goodwill towards our European customers, we are also paying any import duties and charges for orders to the EU or EEC placed by customers with an EU billing address which are shipped directly from the UK for logistical reasons.

We are working hard to ensure that all in-stock orders arrive as quickly as possible. Nevertheless, items that are not in stock in our Netherlands location may take slightly longer to reach you than usual. All in-stock orders are fulfilled promptly via tracked courier services to ensure that your order reaches you as soon as possible.

Import tariffs, or import duties, are applied at the US border by customs. These are separate to any other clearance fees or taxes, and not something that we are able to control. US customs calculate the tariffs due based on the type of product (e.g. chemical or equipment), where the product originated from, and a number of other factors like whether a free trade agreement applies or whether special duties are due.

Your items will not be released by customs until all applicable import tariffs are paid. We cover these costs on select products across our range, with other import tariffs payable as part of your order. This means that we can ship your items ‘delivered duty paid’ (DDP), which helps your order reach you as quickly as possible and avoids unexpected delivery costs.

To provide the best possible value to our US customers, we are covering the tariffs on select products for a limited time. This includes our range of UK-made equipment, Luminosyn™ polymers, PEDOT:PSS, and more. Look out for the “no tariffs to pay on this item” label below the product price.

Any tariffs due are calculated at checkout or on quote request and are payable with your order so that there are no unexpected costs on delivery.

Although we are based in the UK, not all our products fall under the 10% tariff; tariff calculations are complex and depend on both the country of origin of the specific item and its HS code. We are covering the tariffs on select products, but we cannot cover costs for every item due to our global supply chain.

We are reviewing tariff changes as they are announced by The White House and are working hard to keep our systems up to date. Unfortunately, the 90-day pause does not apply in every case.

For a limited time only, products with the “no tariffs to pay on this item” label will not incur any customs charges. All applicable tariffs for your order will appear as a single line on your quote or invoice.

Please contact us if you would prefer to pay duties on arrival or make your own arrangements.

For products where we are not able to cover the import tariffs, you can pay the duties upfront at checkout or via offline channels. These costs are calculated at checkout or provided upon quote request.

Paying upfront ensures there are no extra fees to pay on delivery. If you prefer to pay duties on arrival or make your own arrangements, please let us know.

Yes, you can request to use your own shipping account or freight forwarder. In these cases, we won't charge duties upfront and can refund any paid at checkout. Our delivery guarantee does not apply in such cases, and you will be charged any tariffs due when your order clears customs.

No. If duties and taxes are paid in advance via our website or team, you should not receive any additional customs invoices or courier bills.

Any tariffs are costed separately from the product and shipping prices at checkout and will appear as a separate line item on your invoice.

No, we still offer free shipping on qualifying orders, with premium tracked shipping as standard. Our US delivery guarantee is designed to minimise extra costs and customs surprises.

Yes, our US Delivery Guarantee applies to all 50 states. Delivery times may vary slightly by location, but the guarantee remains the same.

Our online checkout uses a third-party tool to estimate tariffs. Customs duties are complex, and the amount actually charged may vary. If we over-estimate the charges, then we offer a voucher scheme as part of our US Delivery Guarantee. If we under-estimate the charges, then we cover the difference and there is nothing further for you to pay. Differences may occur between online estimates and those provided by our customer care team.

Delays at customs are uncommon but can happen. We monitor orders and work to ensure timely arrival. If your order is delayed for inspection, we’ll assist you however we can. If tariffs were paid upfront, we’ll cover any related customs charges.
