4. Zan iya samun takardar shaida mai inganci da rahotannin dubawa?
Eh, dukkan tarin bututun ƙarfe an tabbatar da su ta ISO 9001. Duk takardun da ake buƙata, gami da rahotannin ɓangare na uku daga SGS, BV ko wata hukuma da aka amince da ita.
5. Ta yaya ake tattara tarin bututun ƙarfe?
Yana haɗa tarin bututun ƙarfe da bandeji na ƙarfe sannan a keɓe shi da tubalin itace ba tare da lalacewa ba. Ana ba da shawarar shafa mai kariya/naɗewa ko/da kuma maganin saman da aka ambata a sama bisa ga jigilar kaya. Ana samun marufi na musamman.
6. Menene lokacin isarwa?
Lokacin jigilar kaya: Kwanaki 15-30 bayan tabbatar da oda (ya dogara da adadi, ƙayyadaddun bayanai da inda za a je).
7. Shin zai yiwu a yi girma dabam dabam?
Eh, diamita, kauri na bango za a iya keɓance shi bisa ga takamaiman buƙatun abokan ciniki.
