India's industrial machinery industry, anchored in Chapter 84 of the Customs Tariff Act, 1975, accounts for roughly 17 percent of total domestic industrial output. The Bureau of Indian Standards (BIS) has notified 90 eight-digit HSN codes from Chapter 84 as compulsory-certification products, drawing on a controlled pool of 14 Indian Standards (IS codes). The notified pool reaches across the IS 17150 series and predecessor specifications for rotodynamic pumps, IS 1391 for room air conditioners, IS 11329 for hermetic compressors, IS 13252 (harmonised with IS/IEC 62368-1 and represented in the notified set as IS 16542 and IS 16544) for printers and multi-function devices, and IS 302, IS 374, IS 616, IS 8148, IS 10617, IS 12933, IS 15041, and IS 15558 covering downstream and information-technology equipment.
Two schemes dominate. The ISI Mark Scheme, operating under Scheme-I of Schedule-II of the BIS Conformity Assessment Regulations, 2018, governs the pump cohort (HSN 8413 series) under the Centrifugal Pumps (Quality Control) Order, 2023 notified as S.O. 3334(E) dated 27-07-2023 by the Department for Promotion of Industry and Internal Trade, and the refrigerating and air-conditioning appliance cohort (HSN 8415 and HSN 8418 series) under successor refrigerating-appliance Quality Control Orders. The Compulsory Registration Scheme (CRS) under Scheme-II of Schedule-II governs the printer, multi-function device, scanner, and computer-system cohort (HSN 8443, 8470, 8471, 8472 series) under the Electronics and Information Technology Goods (Requirements for Compulsory Registration) Order issued by the Ministry of Electronics and Information Technology. A third instrument, the Machinery and Electrical Equipment Safety Omnibus Technical Regulation (the MWN), extends conformity obligations across a wider machinery perimeter with a compliance deadline of 28-09-2026.
Five operational pain points recur. First, the agricultural-pump duty-cycle dispute: the Centrifugal Pumps Quality Control Order, 2023 nominally covers HSN 8413 monoblock and submersible configurations, but the agricultural-pump sector contests that the duty-cycle assumptions in IS 17150 do not reflect field operation on three-phase rural feeders. Second, the domestic-versus-industrial scope question on HSN 8415 air conditioners and HSN 8418 refrigerators, where notifications target household use but commercial cold-chain units are routinely held at customs pending classification rulings. Third, overlap with the Bureau of Energy Efficiency (BEE) Star Rating regime under the Energy Conservation Act, 2001, where refrigerators, air conditioners, and certain pump categories carry parallel BEE labels conflated with the ISI mark. Fourth, the MWN registration backlog and uneven field guidance ahead of the 28-09-2026 deadline. Fifth, the Authorised Indian Representative (AIR) liability exposure for foreign machinery manufacturers shipping through Singapore, Dubai, or Hong Kong intermediaries — the AIR carries personal statutory liability under Rule 11 of the BIS Conformity Assessment Regulations, 2018.

Who it affects
Indian manufacturers
Indian manufacturers of centrifugal pumps, hermetic compressors, room air conditioners, household refrigerators, printers, and computer systems within the 90 notified HSN codes in Chapter 84 must hold a CM/L licence under the ISI Mark Scheme or an R-number under the Compulsory Registration Scheme (CRS) before any notified unit is dispatched to the domestic market. Operating a pump foundry, compressor assembly line, or printer manufacturing unit without the applicable BIS certification exposes the unit to seizure of finished stock, retrospective penalty on past sales, and prosecution under Section 17 of the BIS Act, 2016. Indian small and medium enterprises in the pump cluster around Coimbatore and the air-conditioner contract-manufacturing cluster around Sri City face concentrated enforcement risk because BIS surveillance officers conduct cluster-level surprise inspections.
Foreign manufacturers
Foreign machinery manufacturers exporting pumps, compressors, refrigerating appliances, and valve-bearing assemblies under the ISI Mark Scheme cohort must obtain a Foreign Manufacturers Certification Scheme (FMCS) licence under Scheme-I of the BIS Conformity Assessment Regulations, 2018 before any ISI-marked consignment clears Indian customs, with the typical application-to-grant timeline running 6 to 9 months. The Authorised Indian Representative (AIR) named on the FMCS application carries personal statutory liability under Rule 11 of the BIS Conformity Assessment Regulations, 2018 for sample submission, surveillance-fee remittance, and the foreign factory's ongoing compliance. For the Compulsory Registration Scheme (CRS) cohort covering printers, multi-function devices, scanners, and computer systems, no factory inspection is required and the typical timeline runs 4 to 8 weeks, but the AIR liability provisions still apply and the registration is product-and-model-specific.
Importers
Customs verification at Jawaharlal Nehru Port Trust (JNPT), Mundra, Chennai, and every container-handling Indian port is conducted in real time against the BIS portal (manakonline.in). A lapsed, suspended, or model-mismatched FMCS licence on a pump or compressor consignment, or a stale R-number on a printer or multi-function-device consignment, results in immediate consignment detention at the wharf. Demurrage and ground rent on heavy machinery and electronics cargoes accrue from day 1 of detention. Importers should verify the supplier's CM/L number, R-number, IS standard code, model number, and factory address on manakonline.in before placing each purchase order, because discrepancies identified before dispatch can be resolved while those identified after arrival in India typically cannot.

Speak to an Expert Frequently asked
Does HSN 8413 (pumps) need BIS certification in India?
Yes. Notified centrifugal pumps within the HSN 8413 cohort require BIS certification under the ISI Mark Scheme against the applicable IS standard (the IS 17150 family for clear-water rotodynamic pumps, with predecessor IS specifications for legacy categories), governed by the Centrifugal Pumps (Quality Control) Order, 2023 notified as S.O. 3334(E) dated 27-07-2023 by the Department for Promotion of Industry and Internal Trade. Manufacture, import, sale, or storage of a notified pump configuration in India without a valid CM/L licence is a statutory offence under Section 17 of the BIS Act, 2016.
What is the Machinery and Electrical Equipment Safety Omnibus Technical Regulation (MWN) and what is the deadline?
The Machinery and Electrical Equipment Safety Omnibus Technical Regulation, commonly referred to as the Machinery Omnibus or MWN, is an instrument issued by the Department for Promotion of Industry and Internal Trade under Section 16 of the BIS Act, 2016 that extends conformity-assessment obligations across a wider perimeter of industrial machinery and electrical equipment than the pre-existing product-specific Quality Control Orders. The current notified compliance deadline is 28-09-2026, and registration timelines, scope clarifications, and exemption pathways continue to evolve through subsequent S.O. amendments.
Are imported printers under CRS or another BIS scheme?
Imported printers, multi-function devices, scanners, and similar information-technology hardware within HSN 8443 and HSN 8471 cohorts fall under the Compulsory Registration Scheme (CRS) administered under Scheme-II of Schedule-II of the BIS Conformity Assessment Regulations, 2018, governed by the Electronics and Information Technology Goods (Requirements for Compulsory Registration) Order issued by the Ministry of Electronics and Information Technology. The pathway is sample testing at a BIS-recognised laboratory, submission of the test report on manakonline.in, self-declaration of conformity, and grant of an R-number that must appear on every dispatched unit; no factory inspection is required.
Does the Pumps Quality Control Order cover agricultural pumps?
The Centrifugal Pumps (Quality Control) Order, 2023 notified as S.O. 3334(E) dated 27-07-2023 brings clear-water rotodynamic pumps within HSN 8413, including monoblock and submersible configurations sold to the agricultural sector, within the ISI Mark Scheme against the IS 17150 family. Stakeholders in the agricultural-pump sector have contested the duty-cycle and three-phase voltage assumptions embedded in the underlying IS specifications, but no formal carve-out has been notified, and BIS surveillance treats agricultural-pump models the same as industrial models for licensing and customs verification purposes.
Which industrial machinery in Chapter 84 is excluded from the BIS Quality Control Order regime?
Heavy industrial machinery not specifically named in a Quality Control Order — including machine tools (HSN 8456 onwards), printing machinery (most of HSN 8443 30 series), industrial textile machinery (HSN 84.45 to 84.49), metal-working machinery (HSN 84.62 to 84.66), and food-processing machinery (HSN 84.37 to 84.38) — falls outside the current notified BIS perimeter and is not on the 90 notified HSN list for Chapter 84. The Machinery and Electrical Equipment Safety Omnibus Technical Regulation (MWN) is expected to extend obligations across a wider machinery perimeter from 28-09-2026, but until each sub-category is formally notified through a successor S.O. notification, present BIS coverage remains restricted to the cohorts listed above.
