Notes on these rates

BCD is the statutory tariff rate from a one-time snapshot of the Indian Trade Portal. Exemption notifications (such as 45/2025-Customs) and tariff changes made after the snapshot, including the Finance Act 2026 changes from 1 May 2026, are not applied.
IGST comes from our archived GST table, which still has the 12% and 28% slabs, so it may pre-date the GST rate changes of 22 September 2025. Check the current rate.
AIDC, Health Cess and the SWS exemptions are read from notifications 11/2021-Customs, 08/2020-Customs and 11/2018-Customs as amended (to 16/2026-Customs), and the notifications that lower AIDC for a while. SWS is 10% of BCD, AIDC and Health Cess together (Finance Act 2018, s.110), never of anti-dumping, countervailing or safeguard duty or IGST.
AIDC is Nil (S.No. 17 of 11/2021-Customs, which exempts all goods it does not name).
Not included: GST compensation cess, anti-dumping, countervailing and safeguard duties, and exemptions or concessions such as end-use, EOU/SEZ or project imports.
This does not check whether the import is allowed (DGFT import policy, licences, quality-control orders). The HS code explorer shows the import policy.
This is an estimate, not an assessment. Confirm the duty with your customs broker or ICEGATE's duty calculator before you price a deal.

What buyers pay abroad: import duty in the US, UK, EU and Australia for 8484 20, and China's below.

China: the same goods (8484 20)

China shares the first 6 digits with India and splits them into 10-digit codes of its own: 4 in force under 8484 20. Exporters see what China charges Indian goods; importers see the rebate and licences their Chinese supplier deals with.

China's tariff for these goods
China code	Goods	Duty on Indian goods	MFN	Import VAT	Export rebate	Licences
8484.20.00.10	Rotary shaft seals resistant to UF6 corrosion耐UF6腐蚀的转动轴封	5%China's provisional rate, lower than MFN	8%	13%	13%	3
8484.20.00.20	Rotary shaft seals转动轴封	5%China's provisional rate, lower than MFN	8%	13%	13%	3
8484.20.00.30	Rotary shaft seals for MLISMLIS用转动轴封	5%China's provisional rate, lower than MFN	8%	13%	13%	3
8484.20.00.90	Other mechanical seals其他机械密封件	5%China's provisional rate, lower than MFN	8%	13%	13%	None

India is a member of the Asia-Pacific Trade Agreement (APTA). With an APTA certificate of origin, Indian goods pay China's APTA rate where the line has one; China applies the lower of that and its provisional rate.
The export VAT rebate is what China refunds its own exporters. When China cuts it, Chinese export prices tend to rise.
