Kumtunda kwa unyolo wamakampani a nitrocellulose ndi thonje woyengedwa, asidi wa nitric ndi mowa, ndipo minda yayikulu yogwiritsira ntchito kunsi kwa mitsinje ndi ma propellants, utoto wa nitro, inki, zinthu zama celluloid, zomatira, mafuta achikopa, kupukuta msomali ndi zina.
Zida zazikulu za nitrcellulose ndi thonje woyengedwa, asidi wa nitric, mowa, ndi zina zotero. Xinjiang, Hebei, Shandong, Jiangsu ndi malo ena akupitiriza kumanga ntchito woyengedwa thonje, ndi mphamvu makampani pang'onopang'ono kukodzedwa, kupereka zipangizo zokwanira kupanga nitrocellulose.
Kupanga kwa thonje woyengedwa ku China mu 2020 kudzakhala pafupifupi matani 439,000. Kupanga kwa nitric acid kunali matani 2.05 miliyoni, ndipo kupanga mowa wothira kunali malita 9.243 miliyoni.
Nitrocellulose waku China amatumiza makamaka ku United States ndi Vietnam, maiko awiriwa adawerengera theka la nitrocellulose yapakhomo.Data ikuwonetsa kuti, mu 2022, kutumiza kwa nitrocellulose ku China ku United States ndi Vietnam kunali matani 6100 ndi matani 5900, kuwerengera 25.5% ndi Arabia nitrocellulose 24.8% ku Malaysia. 8.3%, 5.2% ndi 4.1% motsatana.
Pakuyerekeza ndi kuitanitsa ndi kutumiza kunja kwa nitrocellulose, sikelo yaku China ya nitrocellulose ndi yokulirapo kuposa yotengera kunja. Kuitanitsa kwa nitrocellulose ndi pafupifupi matani mazana, koma kutumizidwa kunja kuli pafupifupi matani 20,000. Mwapadera, mu 2021, kufunikira kwapadziko lonse lapansi ndikutumiza kunja kudakwera kwambiri, kufika pachimake matani 28,600 mchaka chaposachedwa. Komabe, chifukwa cha COVID-19 mu 2022, kufunikira kudatsika mpaka matani 23,900. Potengera kunja, kulowetsedwa kwa nitrocellulose kunali matani 186.54 mu 2021 ndi matani 80.77 mu 2022.
Malinga ndi ziwerengerozo, kuyambira kotala zitatu zoyambirira za 2021, kuchuluka kwa nitrocellulose ku China kunali madola 554,300 aku US, kuwonjezeka kwa 22.25%, ndipo ndalama zotumizira kunja zinali $ 47.129 miliyoni zaku US, kuwonjezeka kwa 53.42%.
