Rau ibhydraulic teb sib koom ua ke, qhov tsim nyog HS (Harmonised System) kev faib tawm yog nyob ntawm tus qauv tsim thiab kev siv ntawm kev sib koom ua ke. Qee cov lej siv feem ntau yog:
HS 8483.60 ("Clutches thiab ncej couplings (xws li universal pob qij txha)") - nquag siv rau rotating mechanical pob qij txha.
HS 8487.90 ("Cov khoom ntawm cov tshuab thiab cov cuab yeej siv tshuab... tsis tau teev lossis suav nrog lwm qhov") - tshwm sim hauv cov ntaub ntawv ntshuam/export rau cov pob qij txha.
HS 7307.29 ("Tube lossis yeeb nkab fittings ... ntawm hlau los yog hlau - lwm yam") - hais nyob rau hauv US kev lis kev cai txiav txim rau ib tug stainless hlau kua rotary union coupling.
Kev pom zoo:
Yog hais tias lub hydraulic teb sib koom ua ke yog ib tug neeg kho tshuab coupling / union siv nyob rau hauv hydraulic systems (rotating union tso kua dej thaum rotating), tej zaum yuav HS 8483.60 los yog HS 8487.90.
Yog tias nws yog cov yeeb nkab haum ua los ntawm cov hlau, HS 7307.29 yuav siv tau.
Vim hais tias lub teb chaws tariff lub sij hawm yuav txawv, koj yuav tsum tau xyuas nrog koj cov kev lis kev cai hauv zos / HTS [USA] los yog ntshuam cais cov cai rau koj ib feem.
