Choosing a Crust Leather Supplier in India: Grades, Thickness and 5% GST (2026)
Updated: 23 hours ago
Crust leather is hide that has been tanned, retanned, dyed, fatliquored and dried, but not yet finished. When you buy from a crust leather supplier in India, it is billed under HSN 4104, 4105 or 4106 at 5% GST as of November 2026, and you should specify tannage, selection grade, thickness and area tolerance in writing.
This guide is for Indian footwear and leather-goods factories, finishers, upholstery cutters and leather traders, from Agra, Kanpur and Kolkata to Chennai, Delhi NCR and Punjab, who buy crust to dye, finish or emboss in-house. Updated November 2026.
Key Takeaways
Crust is the dry, unfinished stage between wet blue (or wet white) and finished leather; bovine crust falls under HSN 4104 41 and 4104 49.
GST on tanned and crust hides (HSN 4104 to 4106) is 5% as of November 2026: 2.5% CGST plus 2.5% SGST within a state, or 5% IGST between states.
India's export duty on crust leather has been nil since 2 February 2025, while wet blue still carries 20%.
Specify thickness measured to ISO 2589 and area measured to ISO 11646; 1 m² equals 10.764 sq ft.
Agree the selection grade, tannage and storage conditions in writing before the first lot ships.
What is crust leather, and how is it different from wet blue and finished leather?
Crust is leather after tanning and drying but before surface finishing. Wet blue is chrome-tanned hide still in the wet state, and finished leather has already been coated, printed, embossed or plated to its final look.
Indian customs headings follow the same split. Heading 4104 separates hides "in the wet state (including wet-blue)" from hides "in the dry state (crust)", while heading 4107 covers leather "further prepared after tanning or crusting". Buying at crust stage means your own finishing line decides the colour, surface and handle.
Stage | What has been done | Typical HSN | GST (Nov 2026) | Indian export duty |
|---|---|---|---|---|
Wet blue / wet white | Tanned, still wet, not dyed or dried | 4104 11/19, 4105 10, 4106 21/31/91 | 5% | 20% on tanned wet-state hides |
Crust | Tanned, retanned, dyed, fatliquored and dried; no surface finish | 4104 41/49, 4105 30, 4106 22/32/92 | 5% | Nil since 2 Feb 2025 |
Finished | Crust plus surface finish: coating, print, emboss or plating | 4107, 4112, 4113 | 5% | Nil |

Should you buy chrome, vegetable or chrome-free crust?
Choose the tannage by what you will make. Chrome crust suits soft, evenly dyed uppers, linings, garments and upholstery; vegetable crust suits firm belts, insoles, soles and tooled goods; chrome-free crust is for buyers who need metal-free leather.
Tannage | Typical handle | Common uses | What to check |
|---|---|---|---|
Chrome crust | Soft to semi-firm, even dye uptake | Shoe uppers, linings, garments, upholstery | Chromium VI result if the finished goods go to the EU or UK |
Vegetable crust | Firm, takes burnishing and tooling, darkens with age | Belts, straps, insoles, soles, saddlery, tooled goods | Firmness suits your cutting and edge finishing |
Chrome-free (wet white) crust | Depends on the retanning system | Products sold with metal-free or chrome-free claims | Written confirmation of the tanning system used |
For a deeper comparison of the two main tannages, read chrome-tanned vs vegetable-tanned leather.
How is crust leather graded and selected?
There is no single national grading standard: each tannery sorts crust into its own selections, usually by grain defects and the share of usable cutting area. A grade letter on a quotation means little until you have seen hides from that grade.
Ask for the supplier's grade definitions in writing, including what an A, B, C or tannery-run (TR) selection allows.
Request two or three representative hides per grade, not a single best hide.
State whether corrected-grain (buffed) crust is acceptable for your article.
Agree how scars, veins, tick marks and loose grain will be judged, and the cutting yield you expect.
Fix a sorting tolerance per lot and what happens to off-grade hides.
What thickness should you specify for crust leather?
Specify thickness by end use, as a range with a tolerance, measured by the method in ISO 2589. Finishing, milling and plating can change the final substance slightly, so agree whether the figure applies to the crust or to the finished leather.
End use | Typical thickness to discuss |
|---|---|
Men's shoe uppers | 1.2 to 1.6 mm |
Women's shoe uppers | 1.0 to 1.2 mm |
Linings, garments and jackets | 0.6 to 0.9 mm |
Upholstery | 0.9 to 1.3 mm |
Belts and straps (vegetable crust) | 3.0 to 4.0 mm |
These are common industry ranges, not a fixed specification. Confirm them against your pattern, construction and lasting method before you order.
How is crust leather measured and invoiced in India?
Crust hides are normally sold by area in square feet, measured by machine, with an area statement for each lot. The standard method is ISO 11646 (Leather — Measurement of area), and 1 m² equals 10.764 sq ft.
Ask for a per-hide area statement with every invoice and spot-check a few hides on receipt.
Agree an area tolerance for the lot before dispatch.
Compare quotes per sq ft on the same tannage, grade, thickness and delivery terms.
Remember that milling and finishing change the area slightly, so compare crust with crust, not with finished leather.

Which tests should you ask a crust leather supplier for?
Ask for tests that match the finished product and its market: physical tests for every article, and chemical tests whenever the finished goods will be exported.
Thickness: ISO 2589.
Tensile strength and elongation: ISO 3376.
Tear load: the ISO 3377 series.
Chromium VI content: ISO 17075, important for EU and UK buyers; see our chromium VI testing guide.
Dye uptake and shade: judged against an approved swatch, as described in our leather colour matching guide.
What GST and HSN codes apply to crust leather in India?
Crust leather is taxed at 5% GST as of November 2026. Entries 281 to 283 of Schedule I to Notification 9/2025-Central Tax (Rate) list "tanned or crust hides and skins" of HSN 4104, 4105 and 4106 at 2.5% CGST, with matching SGST.
Bovine (including buffalo) crust: 4104 41 (full grains, unsplit; grain splits) and 4104 49 (other).
Sheep and lamb crust: 4105 30. Goat crust: 4106 22. Other animals: 4106 92.
Within a state: 2.5% CGST plus 2.5% SGST. Between states, for example Punjab to Uttar Pradesh: 5% IGST.
An e-way bill is needed for inter-state consignments worth more than ₹50,000.
GST-registered manufacturers can usually claim the tax as input tax credit.
Since finished leather also moved to 5% on 22 September 2025 (see our GST on finished leather guide), the tax rate no longer favours crust over finished leather. For Indian traders who export crust, the Council for Leather Exports Budget 2025-26 note confirms export duty on crust was cut from 20% to nil from 2 February 2025.
How should crust leather be stored to prevent mould?
Store crust dry, ventilated and off the floor, because it can absorb moisture and grow mould during the monsoon and humid months.
Keep bundles on pallets or racks, away from walls and wet floors.
Avoid airtight plastic wrapping in humid storage; use breathable covers.
Use stock first-in, first-out and inspect older lots regularly.
For goods in transit, follow our guide to preventing mould on leather shipments.

Frequently Asked Questions
What is the difference between crust leather and finished leather?
Crust is tanned, dyed and dried but has no surface finish, so you can still change its colour, coat it, emboss it or plate it. Finished leather has already had that surface work and is ready to cut. In India both are taxed at 5% GST as of November 2026.
I run a shoe factory in Agra. What GST will I pay on crust leather bought from a Punjab supplier?
A supply from Punjab to Uttar Pradesh is inter-state, so you pay 5% IGST on crust under HSN 4104, 4105 or 4106. The consignment needs an e-way bill if it is worth more than ₹50,000. If you are GST-registered, you can usually claim the IGST as input tax credit.
Can I get a crust leather sample before placing a bulk order?
Yes. Ask Sanwas International for sample hides from the grade you plan to buy, and it is good practice to request two or three representative hides per grade rather than one. Bulk quantities are then quoted per square foot for the agreed tannage, grade and thickness.
Is it cheaper to buy crust and finish it myself than to buy finished leather?
It depends on your finishing capacity. Crust gives you control over colour and surface, but you take on finishing chemicals, labour, rejects and yield risk. Since crust and finished leather now both carry 5% GST, compare the total cost per usable square foot after finishing.
Which crust leather should I use for men's shoe uppers?
Most footwear factories use chrome-tanned bovine crust, full-grain or lightly corrected, at around 1.2 to 1.6 mm measured to ISO 2589. Check grain tightness and how the leather behaves on lasting, and approve a sample before ordering in bulk.
