Quartz Crucible HS Code in India: Heading 7017 and What to Check

Why the code matters for a crucible

In batch Czochralski growth a quartz crucible is a consumable, normally used for one pull, so an ingot plant imports crucibles continuously rather than once. The customs code decides the basic duty paid on every shipment, the IGST charged at import, and how smoothly consignments clear.

A code that is wrong, or applied inconsistently between shipments, can lead to differential duty, interest and delays later. A crucible's HS code has no bearing on ALMM List-III, which looks at whether ingots and wafers come from an enlisted manufacturer, not at how consumables were classified.

Heading 7017 and the fused-quartz line

Chapter 70 of the tariff covers glass and glassware. Heading 7017 is laboratory, hygienic or pharmaceutical glassware, whether or not graduated or calibrated, and its first tariff item, 7017 10 00, is for goods of fused quartz or other fused silica. The other lines in the heading cover other low-expansion glass and remaining glassware.

Fused quartz is a glass made by melting high-purity quartz sand, which is how a Czochralski crucible is produced, by arc fusion in a rotating mould. That is why importers and tariff listings most often point a quartz crucible to 7017 10 00. Tariff aggregators such as Eximguru list that line with 10% basic customs duty and 18% IGST, with import policy shown as free.

Why the fit is not perfect

The heading's wording is about laboratory, hygienic and pharmaceutical glassware. A 28- or 32-inch crucible that holds hundreds of kilograms of molten silicon in a crystal puller is an industrial article, not lab ware. Classification follows the General Interpretative Rules and the explanatory notes to the Harmonized System, and reasonable people can read them differently for an industrial fused-quartz vessel.

In practice, shipment records and supplier invoices show more than one choice, including other lines in chapter 70. A supplier's export code is a useful hint but not binding in India: the system is harmonised only to six digits, and the eight-digit Indian lines are national.

Why heading 6903 is usually not the answer

Heading 6903 names crucibles explicitly, alongside retorts, muffles, nozzles and tubes, which is why it shows up in searches. But it covers refractory ceramic goods, and its sub-lines are framed around ceramic compositions such as alumina-rich bodies. Fused quartz is a glass, not a fired ceramic, so chapter 70 is the usual starting point for a fused-quartz crucible.

The distinction matters in a puller's hot zone, which also contains graphite and other refractory parts. Those are separate articles with their own classification and should not be declared under the crucible's code by default.

Duty and GST: read the listings with care

The 10% basic customs duty and 18% IGST shown for 7017 10 00 come from third-party tariff listings, not from the official schedule, and rates can change with each Budget and notification. Check the current Customs Tariff and the applicable IGST rate notification for the date of import.

We do not publish landed-cost workings here. Duty, exchange rates, freight and input-tax treatment differ by importer and shipment, and should be modelled for the specific project.

How to get a classification you can rely on

Most importers settle classification with a licensed customs broker and keep the same, documented position across shipments. Where volumes are large or the position is contested, India's Customs Authority for Advance Rulings can give a binding ruling under Section 28H of the Customs Act, applied for in Form CAAR-1 before the Delhi or Mumbai bench, depending on the applicant's state.

A clear technical description helps any route: say the item is a fused-quartz crucible for Czochralski silicon crystal growth, and give its diameter, purity grade and any inner-surface coating.

• Describe the goods precisely on the invoice and packing list
• Ask the supplier for its export HS code, then check the Indian eight-digit line
• Confirm basic duty and IGST against the current CBIC tariff and notifications
• Keep one documented classification across shipments
• Consider an advance ruling where the amounts at stake justify it
