Auxiliary plants for use with boilers of heading 8402 or 8403
Auxiliary plants for boilers (economisers, superheaters, soot removers, gas recoverers)
HSN 8404 10 00 (auxiliary plants for use with boilers of heading 8402 or 8403) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code, bill of entry, commercial invoice, packing list. Other equipment within Chapter 84 — including the boilers themselves under headings 8402 and 8403 — may carry distinct compliance obligations, making precise tariff classification essential.
The absence of compliance at this tariff line does not extend to the primary boiler equipment with which these auxiliary plants operate; boilers and steam-generating units under headings 8402 and 8403 attract their own regulatory scrutiny, and a customs re-classification of auxiliary plant as integral boiler equipment can trigger retrospective compliance and detention. Verify that the goods are correctly described as auxiliary plant — not as parts of a boiler or as pressure vessels — before relying on the absence of compliance at this line.
