Curious about the manufacturing chain.

If most of our Nitrocellulose is imported, is most of what we’re doing actually just postprocessing?

Like, different retardants for different rounds?

Couldn’t find any good articles online.

That’s from 1898.

Actually made my own black powder and nitrocellulose for fun, when I was much younger.

Looking for clues about our present manufacturing chain.

We “import” nitrocellulose.

As bulk substrate?

As a fully processed product?

From whom?

That kind of stuff.

It's been my understanding for a long time that most of the nitrocellulose in the US is imported and most of that which is imported comes from China.

Maybe this'll give you a good idea where it's all coming from:

I’m beginning to think that it’s imported as a base substrate and tweaked locally (?).

Kind of like how oil is managed, wit additives + detergents getting incorporated at the destination (?).

I don't know, but I'd guess too it's likely.

I think it is for solid rocket propellants.

On further reading, 90% of China’s Cellulose destined for the Nitrocellulose market is sourced from cotton grown in…

…Xinjiang.

Weeghurland.


Recalling what was stated in a recent article titled “China’s New Export Restriction Choke Hold on Critical U.S. Ammunition Components, Are You Prepared?”

…Did someone put some serious spin on it? Like China having a “chokehold” on the US supply chain?

The thing is, we levied SANCTIONS on cotton products from Xinjiang.

Because, human rights and genocide and forced sterilization and suppression of language and oppression and stuff :ROFLMAO:

Meaning - neither we nor our allies can purchase said products, moreso products with added value down the line - including Nitrocellulose.

This won’t be the first time we shot ourselves in the foot.

This is interesting…

I don't know much about the supply lines of the base material. I know there are some US manufacturers that nitrate cellulose, but no idea on what % that is. I believe I've heard that some comes from Canada, also.

But as far as powder production, that is where the nitrocellulose is formed into balls or cylinders or flake, then typically in water the NG and retardants are added, and it's dried and graphite coated. The specifics of how all of that happens is way out of my depth or knowledge.

Guncotton: Why Europe needs China of all countries for more ammunition​

A cotton field in Xinjiang.

There are many different perspectives on the war in Ukraine. However, almost all experts agree on one point: Ukraine urgently needs more ammunition for its defense. While aid from the USA is currently uncertain due to the election campaign, Europe wants to supply – and is even building new production facilities to do so.

In addition to ammunition factories, however, there is also a lack of the necessary raw material for ammunition, commonly known as guncotton. The problem is that Europe is largely dependent on China, which is so closely allied with Russia.

European manufacturers import an indispensable component for ammunition from the People’s Republic – cellulose nitrate, also known colloquially as nitrocellulose or guncotton – or its precursor, linter cotton.

70 percent of guncotton comes from China​

Linters are cotton fibers that are too short to be spun. The website of the German armaments company Rheinmetallstates: “For military requirements, a uniformly nitrified nitrocellulose made from bleached linters is used or, alternatively, blends of two to three different nitrified nitrocellulose types.”

However, Europe only has a very small cotton industry – in contrast to the USA. The EU therefore has to buy from abroad. Europe imports around 70 percent of these fibers from China, Rheinmetall CEO Armin Papperger recently admitted in the British newspaper “Financial Times”. He fears that China could stop the supply of liners at any time for political reasons.

This is not a completely absurd idea. Time and again, China uses its trading power to achieve political goals. Sometimes certain products are no longer exported, sometimes they are simply no longer imported. Countries such as South Korea, Japan, but also Lithuania and France can report on such processes.

Three projects could be put to the test​

The German government has also recognized the risk of potential restrictions and has clearly stated this in its China strategy. The solution: de-risking. But now a kind of multiple staircase joke of history is looming. Because in order to solve the ammunition problem quickly, the West must abandon three of its plans vis-à-vis China – at least temporarily.

  • Politics: The West is actually urging China to stay out of the war as a partner of the Russian aggressor. However, it is now dependent on China becoming more involved – and keeping the European arms industry running through its deliveries.
  • Economy: Actually, the West – especially Germany with its own China strategy – no longer wants to buy so much and so unilaterally from China. But now they urgently need the raw materials for ammunition.
  • Human rights: The West actually wants to avoid Chinese products from the province of Xinjiang, as it is difficult to check whether they have been produced with the help of forced labor. However, a large proportion of Chinese guncotton comes from Xinjiang.

No time for de-risking​

But de-risking is a process that takes time. Something that Europe does not have in the case of the missing ammunition. EU foreign policy chief Josep Borrell described the situation as “dramatic”. Ukraine is running out of ammunition on the front line, especially artillery shells, warned Borrell. And the EU could not deliver anywhere near the quantities of ammunition it had promised.

The plan is now to increase production of the most important NATO artillery calibers to 1.5 million units per year by the end of 2024. Ammunition factories are to be built quickly to achieve this. Chancellor Olaf Scholz took over the ground-breaking ceremony for a Rheinmetall factory in Lower Saxony, while Minister Robert Habeck is looking into shorter approval procedures. But all this doesn’t just take time. It also requires the necessary raw materials from China.

Risk of uncertain deliveries from China​

And according to Papperger, there is a risk of problems if Beijing decides it no longer wants to supply. “That is the reason why we are currently buying as much as possible to fill our warehouses“, the Rheinmetall boss told the FT. So far, the deliveries from China have arrived. “But the point is that Europe should be independent in the long term”, warned the Rheinmetall boss.

Supply problems are already being complained about elsewhere. EU Internal Market Commissioner Thierry Breton, for example, reported initial import problems. The supply of cotton linters from China was stopped “a few months ago as if by chance”, said Breton. In mid-August, Beijing also placed the metal antimony, which is frequently used in ammunition and other military applications, under export controls, similar to those for the metals gallium and germanium, for which Chinese exporters have had to apply for licenses since then.

Chinese experts concede in the Hong Kong newspaper South China Morning Post that China certainly has scope to reduce exports of nitrocellulose for geopolitical reasons – but immediately add that the leadership in Beijing will not use this as a means of exerting pressure.

Problem case Xinjiang​

EU Internal Market Commissioner Breton sums up the current situation in sobering terms: “To produce the powder, we need a special type of cotton, and most of it comes from China.” But from where in China? This is where the next problem lies. Almost 90 percent of Chinese cotton comes from the province of Xinjiang, where the Muslim Uyghur minority is oppressed.

Adrian Zenz has become famous for his Xinjiang research. He once uncovered the extensive Chinese camp system in the region. Now the scientist from the Victims of Communism Memorial Foundation in Washington warns that hundreds of thousands of Uyghurs are being forced to work in Xinjiang’s cotton industry.

In the fight against forced labor, the West is trying to ensure that such goods are no longer sold in Europe or the USA by means of corresponding supply chain laws. And so Europe is faced with a political and an economic dilemma, as well as a moral one: Chinese linter cotton is needed to quickly produce ammunition for Ukraine. However, it is almost inevitable that nitrocellulose produced in China will ultimately be supplied from Xinjiang.

Information is vague, conflated by “Nitrocellulose Lacquer,” which is not a propellant.

The article mentions TNC…

It's been my understanding for a long time that most of the nitrocellulose in the US is imported and most of that which is imported comes from China.

Maybe this'll give you a good idea where it's all coming from:

This helped…

This looks like Nitrocellulose Lacquer, based on the solution described and the buyer (for those really nice finishes on your geee - tars!)…

…while this one’s for propellant.

Taiwan imports cotton primarily from the USA, then Australia and India (or so Google AI claims) - almost entirely to fuel its textile industry.

They ship a little bit back as propellant.

The Nitric Acid + Sulfuric Acid step’s all done overseas due to hazardous waste / environmental regulations.

We have no true domestic capacity for this step.

Under the “China” link:

Didn’t realize how small our supply chain was.

The cotton we export to our partners, on top of what they import independently from other sources - what they end up processing into substrate for propellant is minuscule compared to what China provided.

The big joke is, we Xinjianged ourselves out of our own main supply, both propellant and non - propellant varieties.

It doesn’t look like they were choking us (but I wouldn’t be surprised if they decided to, can’t blame them), our own sanctions and trade regulations did this.

Talk about dumb…
