I-SHS ikwaziwa ngokuba yi-dithionite concentrate, i-sodium dithionite okanye i-sodium dithionite (Na2S2O4). Umgubo omhlophe okanye ophantse ube mhlophe, ongenazo izinto ezimdaka ezibonakalayo, ivumba elibi. Ingahlelwa phantsi kweekhowudi zerhafu 28311010 kunye ne-28321020.
Iimveliso ezisebenzisa inkqubo ye-galvanizing kunye nenkqubo ye-sodium formate zingasetyenziswa ngokutshintshana kwiindawo ezininzi. Abantu abakwishishini lasekhaya bathi nangona abasebenzisi beshishini le-denim (elaphu) bakhetha iimveliso zenkqubo ye-zinc ngenxa yokuvelisa kwazo uthuli oluncinci kunye nozinzo oluhle, inani labasebenzisi abanjalo lilinganiselwe kwaye uninzi lwabathengi basebenzisa ezi mveliso ngokujikeleza. Ngokwesaziso esisemthethweni, sithunyelwe kwi-DGTR.
Kwishishini lempahla, i-sodium dithionite isetyenziselwa ukudaya i-vat kunye nedayi ye-indigo, kunye nokucoca amalaphu efayibha yokwenziwa ukuze kususwe idayi.
Kunyaka ophelileyo, i-DGTR yaqala uphando oluchasene nokulahla inkunkuma kwaye ngoku icebisa ukuba kuhlawuliswe i-ADD elingana nomda wokulahla inkunkuma kunye nomda womonakalo ukulungisa umonakalo kwishishini lasekhaya.
Le arhente icebisa irhafu ye-C$440 ngetoni nganye (MT) kumsi osetyenziswa ngumntu osuka eTshayina okanye othunyelwa kwamanye amazwe. Ikwacebise irhafu ye-$300 ngetoni nganye kwi-SHS evela okanye ethunyelwa kwamanye amazwe evela eMzantsi Korea.
I-DGTR ithe i-ADD iya kuhlala isebenza ixesha leminyaka emihlanu ukususela kumhla wokwaziswa nguRhulumente waseIndiya ngalo mba.
