Hydroxyethyl methylcellulose (HEMC) ke motsoako oa lik'hemik'hale o sebelisoang haholo ho thepa ea mohaho, liphahlo, lihlahisoa tsa lik'hemik'hale tsa letsatsi le letsatsi le masimo a mang. E na le mesebetsi e mengata e kang ho tiisa, ho emisa, emulsification, le ho etsa lifilimi. Ho utloisisa le ho tsebahatsa ka nepo tsamaiso ea machaba ea likhoutu tsa thepa (HS code) ea hydroxyethyl methylcellulose ke ntho ea bohlokoa haholo bakeng sa khoebo ea machaba, phatlalatso ea meetlo le ho latela melaoana e amehang.
1. Bonolo ba khoebo ea machaba
Khoutu ea HS (Harmonized System Code) ke mokhoa o sebelisoang machabeng oa ho hlophisa thepa le mokhoa oa ho khouta o ntlafalitsoeng ke World Customs Organisation (WCO). E sebelisoa ho tsebahatsa mefuta e fapaneng ea thepa le ho netefatsa ho ts'oana ha tlhaloso ea thepa le ho hlophisoa khoebong ea machaba. Bakeng sa lik'hemik'hale tse kang hydroxyethyl methylcellulose, likhoutu tse nepahetseng tsa HS li ka thusa barekisi le barekisi ba kantle ho naha ho hlakisa mefuta ea thepa le ho qoba tieho ea tumello ea thepa le litaba tse ka bang teng tsa molao tse bakoang ke ho aroloa ho fosahetseng. Khoutu e nepahetseng ea HS e thusa ho nolofatsa ts'ebetso ea khoebo ea machabeng, ho ntlafatsa ts'ebetso ea phallo ea lekhetho, le ho fokotsa likhohlano le litšenyehelo tse sa hlokahaleng.
2. Palo ea litefiso le lekhetho
Litefiso tsa litefiso tsa thepa e fapaneng li khethoa ho ipapisitsoe le likhoutu tsa HS. Ho arola hydroxyethyl methylcellulose ka nepo le ho fana ka khoutu ea HS e tsamaellanang ho ka etsa bonnete ba hore meetlo e bala ka nepo mesebetsi le makhetho a lefuoang. Sena ke sa bohlokoa haholo bakeng sa lik'hamphani, kaha ho se bale makhetho le litefiso ho ka lebisa tahlehelong ea moruo kapa likhohlano tsa molao. Ho feta moo, linaha tse ling li ka kenya ts'ebetsong phokotso ea litefiso kapa litokollo tsa thepa e nang le likhoutu tse itseng tsa HS. Ho tsebahatsa likhoutu tsa HS ka nepo le hona ho ka thusa lik'hamphani ho thabela liphekolo tsena tse khethehileng le ho fokotsa litšenyehelo tsa ho reka kantle ho naha.
3. Ikamahanye le melao ea machaba le ea naha
Linaha le libaka tse ngata li na le litlhokahalo tse thata tsa taolo le tumellano bakeng sa thomello le ntle ea lik'hemik'hale. Likhoutu tsa HS ke sesebelisoa sa bohlokoa bakeng sa mekhatlo ea taolo ho tseba le ho laola lik'hemik'hale. Bakeng sa lintho tsa lik'hemik'hale tse kang hydroxyethyl methylcellulose, khoutu e nepahetseng ea HS e thusa ho netefatsa hore ho latela melao e nepahetseng e kang tšireletso ea lik'hemik'hale le tšireletso ea tikoloho. Ka mohlala, lik’hemik’hale tse ling li ka ’na tsa thathamisoa e le thepa e kotsi ’me li tlameha ho latela melao e itseng ea lipalangoang le ea polokelo. Likhoutu tse nepahetseng tsa HS li ka thusa batho ba amehang ho utloisisa melaoana ena le ho nka mehato e nepahetseng ho qoba ho tlola melao le melaoana.
4. Lipalopalo le tlhahlobo ea maraka
Likhoutu tsa HS li phetha karolo ea bohlokoa lipalo-palo tsa khoebo ea machaba. Ka likhoutu tsa HS, mebuso, lik'hamphani le litsi tsa lipatlisiso li ka sala morao le ho sekaseka lintlha tse joalo ka bongata ba thepa e tsoang kantle ho naha le mekhoa ea 'maraka ea mofuta o itseng oa thepa. Sena se bohlokoa haholo bakeng sa ho theha maano a khoebo, maano a mebaraka le liqeto tsa khoebo. Bakeng sa lik'hamphani tsa tlhahiso le thekiso ea hydroxyethyl methylcellulose, ho utloisisa ho potoloha ha eona 'marakeng oa lefats'e ho ka ba thusa ho tsamaisa maemo a' maraka le tlhahlobo ea tlholisano, e le ho theha maano a atlehileng a mmaraka.
5. Tšebelisano le tšebelisano ea machaba
Mehleng ea ho ikopanya ha lichaba tsa lefatše, likamano tsa khoebo pakeng tsa linaha li ntse li atamela haholoanyane. E le ho phahamisa tsoelo-pele e thellang ea khoebo ea machaba, linaha li lokela ho boloka botsitso tabeng ea ho arola thepa le melao ea khoebo. Joalo ka tekanyetso ea maemo a akaretsang ea thepa, khoutu ea HS e khothaletsa khokahanyo le tšebelisano ea machaba. Bakeng sa thepa e kang hydroxyethyl methylcellulose, HS code e kopantsoeng e ka fokotsa litšitiso tsa puisano le ho se utloisisane ha litšebelisano tsa ho tšela moeli, le ho thusa ho ntlafatsa ponaletso le katleho ea khoebo ea machaba.
Khoebong ea machaba, khoutu ea HS ha se sesebelisoa sa ho arola thepa feela, empa hape ke motheo oa bohlokoa oa ho balloa ha litefiso, ho lumellana le taolo, tlhahlobo ea 'maraka le tšebelisano ea machaba. Bakeng sa likhoebo le litsebi tsa khoebo tse amehang ho hydroxyethyl methylcellulose, ho bohlokoa ho utloisisa khoutu ea eona ea HS ka nepo. E ke ke ea thusa likhoebo feela ho etsa khoebo ea machabeng ka molao le ka tumellano, empa hape e ka ntlafatsa taolo ea phepelo ea thepa, ho fokotsa litšenyehelo le ho matlafatsa tlholisano ea mebaraka. Ka hona, ho utloisisa le ho sebelisa khoutu ea HS ka nepo ke karolo ea bohlokoa khoebong ea machaba ea sejoale-joale ebile ke mohato oa bohlokoa hore likhoebo li kene 'marakeng oa lefatše.
