Ukungena emakethe yaseBangladesh kuyathembisa, kodwa imithetho engaziwa ingakubamba. Iphutha elilula lezindinganiso lingenza ukuthunyelwa kwakho konke kwenqatshwe, kukubize konke ngesikhathi nangemali.

EBangladesh, gxila ezindinganisweni ze-ASTM, ikakhulukazi i-D1785 yobukhulu bepayipi kanye ne-D2466 yezisekelo zokufaka. Uzodinga nesitifiketi sokuhlolwa kwangaphambi kokuthunyelwa (i-PSI) esidingekayo esivela enhlanganweni evunyiwe ukuze usule amasiko kahle.

Bengiku-call nomlingani wami owayefuna ukunwebeka ezimakethe ezintsha eNingizimu Asia. Wayenesithakazelo esikhulu eBangladesh ngenxa yokukhula kwemboni yokwakha. Sachitha isikhathi sethu esiningi sixoxa ngento abantu abaningi abayinaki: akukhona nje ukuthola amakhasimende. Impumelelo incike ekuhlangabezaneni nezidingo zezwe.amazinga ekhwalithi kanye nezidingo zentelakusukela ngosuku lokuqala. Ukuphutha lokhu kusho ukuthi imikhiqizo yakho ngeke ikwazi ngisho nokuphuma echwebeni. Ake sichaze lokho okufanele ukwazi ngempela.

Yiziphi izindinganiso ze-ASTM zamapayipi e-PVC?

Ubona i-“ASTM” ephepheni lemininingwane yomkhiqizo, kodwa kumane kuyingxubevange yezinhlamvu nezinombolo. Ukukhetha umkhiqizo olandela indinganiso engalungile kusho ukuthi izinto zakho zokufaka ngeke zixhumeke kahle namapayipi endawo.

Izindinganiso ze-ASTM ezibaluleke kakhulu yi-D1785 yamashejuli amapayipi (njenge-Sch 40/80) kanye ne-D2466/D2467 yama-socket kanye nama-thread fittings. Lokhu kuchaza ubukhulu obuqondile bokuxhumeka okuphelele, okuvikela ukuvuza.

I-ASTM imele i-American Society for Testing and Materials. Lezi zindinganiso zisetshenziswa emhlabeni wonke ukuqinisekisa ikhwalithi kanye nokuhambisana. Kumthengisi oqondisa iBangladesh, azikhethwa; ziwulimi lwemakethe. Uma u-oda i-fitting ehambisana ne-American Society for Testing and Materials.I-ASTM D2466, uyazi ukuthi ububanzi bayo besokhethi kanye nokujula kulawulwa ngokunembile. Lokhu kuqinisekisa ukuthi izongena kahle kunoma yiliphi ipayipi le-PVC elenziwe ku-I-ASTM D1785indinganiso. Kususa ukuqagela kanye nengozi yokungafani. Ukuqonda la makhodi kuyisinyathelo sokuqala sokunikeza imikhiqizo ethembekile.

Izindinganiso Eziyinhloko ze-ASTM ze-PVC

Yiziphi izindinganiso zekhwalithi yamapayipi e-PVC?

Amavalvu amabili e-PVC amhlophe angase abukeke efana, kodwa elinye liqinile kanti elinye liyaphuka. Udinga ukwazi ukuthi ungayibona kanjani ikhwalithi ngaphambi kokuthi uthenge, hhayi ngemva kokuba uhlelo lwekhasimende seluhlulekile.

Amapharamitha abalulekile ekhwalithi ukuhlanzeka kwezinto ezibonakalayo (i-PVC eyi-100% engabonakali), ukunemba kobukhulu, isilinganiso sokucindezela, kanye nokumelana nomthelela. Lokhu kuqinisekiswa ngokuhlolwa okufana nokucindezela okuqhumayo kanye nokuhlolwa kokuthamba, okuqinisekisa ukuthembeka kwesikhathi eside.

Ukufakwa kwekhwalithi kuqala ngezinto ezisezingeni eliphezulu. Sisebenzisa kuphelaI-resin ye-PVC engu-100% emsulwaAbanye abakhiqizi bayaxubanai-calcium carbonatenoma izinto eziphinde zasetshenziswa ukuze kwehliswe izindleko. Lokhu kwenza umkhiqizo wokugcina ube buthakathaka futhi uqhekeke kalula, uthambekele ekuqhekekeni ngaphansi kwengcindezi noma lapho ushayisana. Ngaphandle kwezinto, ikhwalithi imayelana nokulawula. Ukukhiqizwa kwethu okuzenzakalelayo kuqinisekisa ukuthi konke ukulingana kuhlangabezana nezindinganiso eziqondile zobukhulu. Bese, senza ukuhlolwa kweqembu okuqinile.ukuhlolwa kokucindezela kokuqhumaIsitshela ukuthi ingcindezi ephezulu kakhulu engayiphatha ngaphambi kokuba yehluleke. Ukuhlolwa kokuthamba kukhombisa ukuthi ingaguquguquka ngaphansi kokucindezeleka ngaphandle kokuqhekeka. Lokhu kuhlolwa kuyisiqinisekiso sakho sokuthi umkhiqizo awuyona nje ipulasitiki emhlophe; uyingxenye eyakhiwe ngobunjiniyela elungele umsebenzi onzima.

Yimiphi imithetho yentela yokungenisa impahla eBangladesh?

Ukuthunyelwa kwakho kufika echwebeni laseChittagong, kodwa kubambekile ngoba ulahlekelwe yidokhumenti eyodwa eyisihluthulelo. Manje ubhekene nezindleko zokugcina zansuku zonke futhi umthengi wakho uqala ukukhathazeka.

Ukuze ungenise eBangladesh, kumele ube nesitifiketi sokuhlolwa kwangaphambi kokuthunyelwa (i-PSI) esivela ejensi evunyelwe yi-NBR. Lesi sitifiketi siyimpoqo ekukhishweni kwezimpahla futhi siqinisekisa ikhwalithi, ubuningi, kanye nenani lezimpahla.

Lona umthetho obaluleke kakhulu kunoma yimuphi umngenisi eBangladesh. IBhodi Kazwelonke Yezimali (i-NBR) idinga ukuthi izimpahla eziningi ezingenisiwe zihlolwe.ngaphambibashiya izwe abazalelwa kulo. Lokhu kubizwa ngokuthiUkuhlolwa Kwangaphambi Kokuthunyelwa, noma i-PSI. Njengomkhiqizi, sisebenzisana nenkampani yokuhlola evunyelwe yi-NBR njenge-SGS, i-Bureau Veritas, noma i-Intertek. Beza efektri yethu, bahlole izimpahla ukuqinisekisa ukuthi ziyahambisana ne-oda lakho, bese bekhipha isitifiketi esivaliwe. Lo mbhalo ufakazela amasiko aseBangladesh ukuthi izimpahla zinjengoba zichazwe futhi ziyahlangabezana nezindinganiso ezidingekayo. Ngaphandle kwalesi sitifiketi, ukuthunyelwa kwakho kuzobhekana nokubambezeleka okukhulu, ukuhlolwa kabusha, kanye nezinhlawulo ezingaba khona. Siphatha le nqubo kubalingani bethu ukuqinisekisa ukuthi ukuthunyelwa kwabo kuhamba kahle.

Iyini ikhodi ye-HS yokufakwa kwamapayipi e-PVC?

Ugcwalisa i-invoyisi yakho yezentengiselwano kanye ne-bill of lading. Ukusebenzisa ikhodi ye-HS engalungile kungaholela ezinteleni zokungenisa ezingalungile, izinhlawulo, noma ngisho nezinsolo zokumemezela okungalungile okuvela kumasiko.

Ikhodi ye-HS eyinhloko yokufakwa kwamapayipi e-PVC ingu-3917.40.00. Le khodi ihlanganisa ngqo "Ukufakwa kwamapayipi, amapayipi namapayipi, epulasitiki." Ukusebenzisa le khodi enembile kuqinisekisa ukuthi ukuthunyelwa kwakho kuhlukaniswe kahle.

IIkhodi yeSistimu Ehlanganisiwe (HS)lulimi lomhlaba wonke lokuhlukanisa imikhiqizo ngokwesiko. Ukuyilungisa kubalulekile. Ake sixoxe kabanzi3917.40.00:

• Isahluko 39:Ipulasitiki nezinto zayo.
• Isihloko 3917:Amapayipi, amapayipi namapayipi, kanye nezinto zokufaka zepulasitiki.
• Isihlokwana 3917.40:Izinto zokufaka.

Leli zinga lokunemba litshela igunya lamasiko eBangladesh ukuthi yini ekhona esitsheni sakho. Le khodi inquma izingaintela yokungenisa impahlauzokhokha. Ikhodi engalungile ingabangela ukubambezeleka isikhathi eside ngenkathi izikhulu zihlela kabusha izimpahla zakho. Njalo qiniseka ukuthi le khodi ibhalwe ngokucacile kuwo wonke amadokhumenti akho okuthumela ukuze uvimbele noma yiziphi izinkinga echwebeni. Kuyimininingwane encane ekusindisa ezinhlungwini ezinkulu.

Isiphetho

Impumelelo eBangladesh idinga ukuqonda amazinga e-ASTM, ukuqinisekisa ikhwalithi, ukuthola isitifiketi se-PSI, nokusebenzisa ikhodi ye-HS efanele. Thola lokhu ukuze wakhe ibhizinisi lokungenisa eliqinile nelinenzuzo.
