How do you ensure NF3 remains uncontaminated during long-term storage?
We benefit from vertical integration in hardware manufacturing. Not only do we produce the gas, but we also manufacture our own cylinders. Through special passivation and electropolishing treatments of the inner walls, we prevent moisture adsorption and metal ion contamination, ensuring the 5N5 high purity remains stable from production to delivery at your facility.
Is NF3 classified as a hazardous material for international transportation?
Yes. According to the International Maritime Dangerous Goods (IMDG) Code, NF3 is classified as a Class 2.2 (non-flammable, non-toxic gas) with a subsidiary hazard of Class 5.1 (oxidizing). Our logistics team holds comprehensive dangerous goods (DG) handling qualifications, and each shipment is accompanied by a complete Material Safety Data Sheet (MSDS) and Certificate of Analysis (COA).
What is the typical lead time for a full container load (FCL) order?
Leveraging our manufacturing bases in China, Taiwan, and India, we maintain a stable supply chain. Depending on the destination port, the typical lead time ranges from 4 to 6 weeks. We support various trade terms, including FOB, CIF, and DDP for major semiconductor hubs.
Why is NF3 better than traditional cleaning gases like CF4 or C2F6?
The core advantage of NF3 lies in its exceptionally high dissociation efficiency. In a plasma environment, it generates a higher concentration of active fluorine atoms, resulting in faster etching speeds and reduced equipment downtime. Additionally, NF3 has a relatively low global warming potential (GWP), aligning better with environmental sustainability trends.
Which international standards do your cylinders comply with?
Our packaging meets the safety regulations of major global markets:
DOT-3AA: For the North American market.
TPED / EN ISO 9809: For the European market.
ISO 9809: A globally recognized standard.
Racks/Cylinder Bundles: Designed to meet high-flow, continuous production needs in semiconductor plants.
What purity grades do you offer for nitrogen trifluoride (NF3) exports?
We provide high-purity grades specifically tailored for the electronics industry:
High Purity Grade (4N 99.99%): Suitable for standard flat panel display (FPD) and solar cell cleaning.
Ultra High Purity Grade (5N to 5N5 99.999% to 99.9995%): The standard for advanced semiconductor processes. This grade strictly limits key impurities such as moisture (H2O), oxygen (O2), and carbon tetrafluoride (CF4), which can affect production yield.
