HSN Code 7323: A Complete Guide to GST & Job Work for Utensils
Commercial Utensil Polishing
Commercial utensil polishing at scale is a throughput and consistency problem -- not just a finishing problem. Any buffing operation can polish one piece correctly. The challenge is maintaining the same surface standard across 5,000 pieces in a single batch, across mixed SS grades, across multiple finish specifications in the same consignment. Our 20-motor buffing array is configured specifically for high-volume throughput with grade segregation, per-unit luster audits at the output stage, and HSN 7323 compliant invoicing on every order. We handle hotelware, catering equipment, commercial kitchenware, and manufacturer job-work batches across SS 202, SS 304, SS 316, brass, and aluminium.

Why Bulk Buffing Quality Is a Throughput Problem, Not Just a Finishing Problem
The failure mode in high-volume commercial buffing is not the first piece -- it is the five-hundredth. As buffing wheels wear through a large batch, compound distribution changes, surface pressure varies, and the output finish drifts from the specification set at the start of the run. On a 100-unit batch this drift is manageable. On a 5,000-unit batch it produces visible finish inconsistency across the consignment -- some pieces mirror-grade, others visibly duller -- which is a quality rejection risk for any manufacturer supplying to hotels, catering operations, or retail. Our 20-motor array addresses this through two mechanisms. First, compound is applied and replenished at controlled intervals rather than run to depletion. Second, every batch includes a per-unit luster audit at the output stage -- not a sample check, a per-unit check -- so finish drift is caught and corrected before packaging, not after delivery. For manufacturers running recurring production cycles, this is the difference between a vendor and a reliable supply chain partner.
Grade Segregation in Mixed-Material Batches
The most common mistake in bulk utensil job-work is applying a single compound protocol to a mixed-grade consignment. SS 202, SS 304, and SS 316 each have different hardness, work-hardening behavior, and response to abrasive compounds. SS 202 over-thins under SS 304 compound pressure. SS 316 under-polishes under SS 202 compound settings because its higher molybdenum content requires more aggressive abrasion to achieve the same surface result. Manufacturers often send mixed consignments because their own production runs mix grades. We accept mixed-grade batches and handle grade segregation on our end -- each grade is assigned its own compound and RPM protocol and processed in separate passes. The finished batch is reassembled and dispatched as a single consignment under one HSN 7323 invoice. For the technical detail on why SS grades require different buffing protocols, see our SS grade buffing guide.
Hotelware and Catering Equipment: What Bulk Job-Work Covers
Commercial hotelware and catering equipment spans a wide range of utensil types -- serving bowls, chafing dishes, food pans, hotel pots, buffet serving pieces, commercial soup pots, and full cutlery sets. Each has different geometry, different surface-to-volume ratios, and different finishing requirements. Flat serving pieces (trays, lids) run faster through the buffing array than deep curved pieces (serving bowls, round pots) because wheel contact geometry changes. We account for this in batch scheduling -- deep curved pieces are allocated longer pass time to ensure full interior coverage. Hotels and catering operations across Mumbai, Thane, Palghar, and Vasai send recurring consignments to us for pre-service restoration polishing between banquet cycles. For ongoing catering clients, we can align dispatch schedules to your event calendar.
Finish Specification for Commercial Batches: Mirror, Matte, or Both
Commercial kitchenware orders are not always a single finish specification. A manufacturer may require mirror interiors on serving bowls and matte exteriors on the same pieces. A hotel may send a mixed batch with different finish requirements per piece type. We handle multi-specification batches within a single consignment -- pieces are tagged by finish requirement at intake, routed through the appropriate machine (20-motor array for mirror, matte precision polisher for satin), and reassembled at dispatch. There is no additional charge for multi-specification processing within the same consignment -- it is accounted for in the batch quote. The Ra value targets for each specification are documented in the order record and verified at the per-unit audit stage. For the technical detail on matte finish Ra values, read our matte specialist finishing guide.
HSN 7323 Job-Work Invoicing: How B2B Input Tax Credit Works
Every commercial utensil job-work order from Raja Buffing Works is invoiced under HSN Code 7323 -- Household articles of iron or steel, including stainless steel utensils. This is the correct HSN classification for buffing and polishing job-work performed on utensils supplied by the client. Under GST job-work rules, the client (the manufacturer or business sending the utensils) retains ownership of the goods throughout the process -- we are performing a service on goods-in-transit, not purchasing and reselling. This means the job-work service charge is GST-eligible, and B2B clients registered under GST can claim input tax credit on the service amount. We issue a full tax invoice with GSTIN, HSN code, service description, and quantity on every batch. For a complete breakdown of how to structure the job-work transaction and what documents you need for ITC eligibility, see our HSN 7323 compliance guide.
Laser Engraving Add-On: Batch Coding, Logo Marking, and Hallmarking
Our 50W fiber laser engraving system is available as an add-on to any commercial job-work batch. Laser engraving adds permanent, high-contrast marks to finished utensils -- batch codes for quality traceability, logo marks for branded hotelware, hallmarks for export certification, or sequential numbering for inventory control. The laser is compatible with all supported metal grades: SS 202, SS 304, SS 316, brass, and aluminium. Engraving is performed after the buffing and finishing stage so the laser mark sits cleanly on the polished surface without interference from buffing compound residue. Batch coding turnaround adds 4-8 hours to standard dispatch time depending on batch size and mark complexity. Mention the laser engraving requirement when requesting a quote and we will include it in the batch schedule.
Dispatch Logistics and Batch Scheduling for Recurring Manufacturers
Standard commercial batches dispatch within 24-48 hours of receipt at our Vasai East facility. Batches of 5,000+ units are scheduled on dedicated processing slots to ensure the full batch runs on a single compound assignment without mid-batch changeovers that can introduce finish variation. For manufacturers running recurring production cycles -- weekly or fortnightly polishing batches aligned to their own production output -- we offer dedicated batch scheduling with fixed dispatch windows. This eliminates the variability of ad-hoc consignment intake and gives your production planning a reliable finishing lead time. We serve manufacturers across Vasai East, Boisar, Palghar, Thane, and the broader Mumbai industrial corridor. Contact us to discuss a recurring batch schedule for your production cycle.
Mirror Finish vs Matte Finish: Which Is Right for Your Batch?

|---|---|---|
| Batch Size | 100 to 10,000+ units per consignment | Same -- both finish types available across all batch sizes |
| Grade Coverage | SS 202, SS 304, SS 316, Brass, Aluminium -- grade-matched compounds per pass | Same grade coverage -- matte precision polisher handles all supported grades |
| Finish Consistency | Per-unit luster audit at output stage -- not sample-based | Per-unit grain-direction check at output stage |
| Mixed Specification Batches | Mirror interior + matte exterior accepted in single consignment | Routed to matte precision polisher -- no additional charge for multi-spec |
| Turnaround | 24-48 hours standard / dedicated slots for 5,000+ unit batches | Same turnaround -- both machines run parallel workflows |
| Laser Engraving Add-On | Available on all grades post-buffing -- adds 4-8 hours to dispatch | Available on all grades post-finishing -- same turnaround addition |

Technical FAQ: Commercial Utensil Polishing
What is the minimum and maximum batch size for commercial utensil job-work?
We accept batches from 100 units upward with no stated maximum. Batches of 5,000+ units are scheduled on dedicated processing slots to ensure the full batch runs on a single compound assignment without mid-batch changeovers. For recurring manufacturers, we offer fixed dispatch windows aligned to your production cycle.
How is HSN 7323 job-work invoicing structured and how do I claim input tax credit?
All job-work is invoiced under HSN Code 7323 (Household articles of iron or steel). Under GST job-work rules, you retain ownership of the goods -- we are performing a finishing service on goods-in-transit. The service charge is GST-eligible and B2B clients registered under GST can claim input tax credit on the amount. We issue a full tax invoice with GSTIN, HSN code, and service description on every batch. For complete compliance documentation guidance, see our HSN 7323 compliance guide.
Can you handle mixed-grade batches with SS 202, SS 304, and SS 316 in one consignment?
Yes. Mixed-grade consignments are accepted and grade segregation is handled on our end. Each grade is assigned its own compound formulation and RPM protocol and processed in separate passes. The finished batch is reassembled and dispatched as a single consignment under one HSN 7323 invoice. No additional charge for grade segregation -- it is included in the standard batch process.
Can a single batch have different finish specifications -- mirror on some pieces, matte on others?
Yes. Multi-specification batches are accepted within a single consignment. Pieces are tagged by finish requirement at intake, routed through the appropriate machine (20-motor array for mirror, matte precision polisher for satin), and reassembled at dispatch. Ra value targets for each specification are documented in the order record and verified at the per-unit audit stage. No additional charge for multi-spec processing.
Do you offer laser engraving or branding as an add-on?
Yes. Our 50W fiber laser engraving system is available as an add-on to any commercial job-work batch. Capabilities include permanent batch coding, logo marking, hallmarking, and sequential numbering for inventory control. Compatible with all supported metal grades. Performed after buffing so the mark sits cleanly on the polished surface. Adds 4-8 hours to standard dispatch time depending on batch size and mark complexity.
How do you maintain finish consistency across large batches of 5,000+ units?
Finish consistency at scale is a throughput management problem. We address it through two mechanisms: controlled compound replenishment at set intervals rather than running wheels to depletion, and a per-unit luster audit at the output stage -- not a sample check, a per-unit check -- so finish drift is identified and corrected before packaging. Batches of 5,000+ units run on dedicated processing slots to eliminate mid-batch grade or compound changeovers that introduce variation.
Do you serve manufacturers outside Vasai -- in Boisar, Thane, Palghar, or Mumbai?
Yes. Our primary dispatch hub is Vasai East (401208) but we accept consignments from manufacturers across Boisar, Palghar, Thane, and the greater Mumbai industrial belt. For recurring manufacturers we can arrange fixed pickup and dispatch windows to remove logistics variability from your production planning. Contact us to discuss your consignment frequency and volumes.
