IBJJF-Compliant BJJ Gi Manufacturer: The Complete 2026 B2B Sourcing Guide
Not all BJJ gis are created equal — and not all manufacturers understand the difference between a gi that looks correct and one that passes IBJJF inspection. This guide covers weave selection, construction tolerances, branding compliance, pricing, and why Sialkot, Pakistan is producing the world's highest-volume competition gis at 50-piece MOQ.

What IBJJF Compliance Actually Requires
The International Brazilian Jiu-Jitsu Federation publishes a detailed General System of Rules that governs every aspect of gi construction for sanctioned tournaments. The rules are not aesthetic guidelines — inspectors measure collar thickness with a ruler, check sleeve openings with a hand insert, and weigh gis on a digital scale. A non-compliant gi results in immediate disqualification, regardless of brand.
For B2B buyers — whether you are launching a BJJ gi brand, outfitting a team, or supplying a martial arts retailer — understanding these specs before you send a purchase order is the difference between a sellable product and a warehouse full of returns. Sialkot Sample Masters has been manufacturing to combat sports specifications since 2009, including IBJJF-legal pearl weave gis for international competition brands. For the deep dive on fabric construction, see our companion post on BJJ gi pearl weave manufacturing in Sialkot. Brands extending beyond grappling into striking disciplines can also review our custom boxing gear manufacturer guide for robes, shorts, and walkout apparel.
IBJJF 2024 Construction Compliance Checklist
- Jacket: white, royal blue, or black only — no patches wider than 7 cm in restricted zones
- Lapel/collar: rigid foam insert, minimum 1.3 cm wide, maximum 4 cm thick
- Sleeve opening ≥ 7 cm gap between sleeve and forearm when arm extended
- Pants: drawstring fastening, no zipper; leg opening ≥ 7 cm at ankle
- Belt loops: minimum 4, evenly spaced, securely bar-tacked
- Woven IBJJF-approved sizing label: A0–A6 (adult), M0–M4 (youth)
- Shrinkage: finished weight must remain ≥ 450 gsm after standard AATCC wash
- No metal hardware anywhere on the gi

BJJ Gi Weave Comparison
Selecting the right weave determines weight class performance, durability, and your retail price point.
| Weave Type | Finished Weight | Durability | Shrinkage (1st wash) | Feel | IBJJF Status |
|---|---|---|---|---|---|
| Pearl Weave(Recommended) | 450–550 gsm | ★★★★★ | 3–5% | Lightweight & stiff | ✅ Legal |
| Gold Weave | 400–480 gsm | ★★★★☆ | 4–6% | Soft, medium weight | ✅ Legal |
| Single Weave | 350–420 gsm | ★★★☆☆ | 5–7% | Lightweight, flexible | ✅ Legal (if ≥450 gsm finished) |
| Double Weave | 700–850 gsm | ★★★★★ | 3–4% | Heavy, rigid | ✅ Legal |
| Bamboo Weave | 430–500 gsm | ★★★☆☆ | 4–6% | Soft, eco-friendly | ✅ Legal (weight permitting) |
Note: All finished weights measured post standard AATCC 135 wash cycle. Single weave must reach ≥ 450 gsm finished to pass IBJJF weigh-in.
Section 03
Construction Specifications: Where Compliance Is Built In
Collar Construction
The collar is the single most-failed component in gi inspection. IBJJF requires a minimum width of 1.3 cm and a maximum thickness of 4 cm across the entire collar run, including the transition from neck to lapel. Sialkot Sample Masters uses a two-layer EVA foam insert (40-shore hardness, 1.5 cm), machine-stitched at 12 SPI with a double-row lockstitch and bar-tacked at both ends. The outer shell is the same pearl weave as the jacket body, ensuring consistent appearance across sizes.
We pre-shrink the collar foam before assembly — a step many low-cost manufacturers skip — preventing post-wash collar ballooning that fails inspection at tournaments even on a gi that initially passed.
Sleeve and Pant Construction
IBJJF mandates a minimum 7 cm gap between the end of the sleeve and the competitor's forearm when the arm is extended. This is a pattern-grading constraint, not a fabric one. Our CAD grading team parameterises sleeve length across A0–A6 to ensure every size meets the 7 cm rule for the 5th-to-95th percentile arm length in each size bracket.
Pants use 10 oz ripstop cotton or 12 oz canvas, depending on tier. Drawstring channels are double-stitched and bar-tacked at both ends; no zipper hardware is used. Ankle opening is graded to maintain ≥ 7 cm clearance. Reinforcement patches at the knee are optional (1000D Cordura or pearl weave double-layer) and do not affect IBJJF compliance. For an overview of our broader combat sports construction capabilities, see our guide on OEM combat and tactical apparel manufacturing.
Belt Loop and Stitching Standards
IBJJF requires a minimum of four belt loops, evenly spaced, securely attached. Our standard is five loops, each bar-tacked with 8–10 SPI reverse-stitch reinforcement and a minimum tensile pull resistance of 150 N — well above the 80 N that a referee is likely to apply during inspection.
All seams critical to gi integrity — side seams, shoulder seams, armhole seams — are reinforced with flat-felled construction or double-needle lockstitch at 12–14 SPI, depending on the tier. This is the same seaming specification we apply to our multi-needle flatlock activewear line, adapted for the higher-friction environment of BJJ gripping and pulling.
Section 04
IBJJF Adult Size Chart
Reference measurements used in our CAD grading system. All gis are pre-washed at 40°C before shipping to account for initial shrinkage and ensure tournament compliance on arrival.
| IBJJF Size | Athlete Height | Athlete Weight | Chest Circumference |
|---|---|---|---|
| A0 | 157–163 cm | 56–65 kg | 88–96 cm |
| A1 | 163–170 cm | 65–73 kg | 96–104 cm |
| A2 | 170–178 cm | 73–82 kg | 104–112 cm |
| A3 | 178–185 cm | 82–93 kg | 112–120 cm |
| A4 | 185–193 cm | 93–105 kg | 120–130 cm |
| A5 | 188–196 cm | 100–120 kg | 128–140 cm |
| A6 | 193–200 cm | 115–140 kg | 136–150 cm |
Youth sizes (M0–M4) available on request. Custom grading for non-standard sizing (tall, big & tall, women's fitted) is offered from 50-piece MOQ per custom size.
Section 05
Branding Within IBJJF Patch Rules
IBJJF allows branding on a gi, but with precise placement and size constraints. Manufacturers who produce gis without knowledge of these rules leave brands exposed to disqualification at the tournament level, which destroys customer trust. Sialkot Sample Masters tech-pack review includes a mandatory compliance overlay that maps every patch, embroidery, or sublimated panel against the current IBJJF patch rules before the sample is cut.
1
Right chest (sponsor area)
Max: 36 cm² — Woven patch or embroidery
2
Left chest (brand area)
Max: 36 cm² — Woven patch or embroidery
3
Upper back (main branding)
Max: 100 cm² — Embroidery or print-on-fabric
4
Right sleeve
Max: 36 cm² — Woven patch or embroidery
5
Left sleeve
Max: 36 cm² — Woven patch or embroidery
6
Pants legs (each)
Max: 36 cm² — Embroidery or sublimated panel
Important: Patches, embroidery, and woven labels must be cleanly finished on the reverse side. Fraying edges or exposed adhesive backing will flag during a thorough inspection at elite tournaments. All Sialkot Sample Masters patches are woven on a shuttle loom and heat-sealed on the reverse before application.
Section 06
Pricing & Lead Times by Tier

Why Sialkot
The World Buys Its Sports Equipment from Sialkot for a Reason
Sialkot, Pakistan has supplied the global combat sports market for over four decades. The city produces an estimated 70–80% of the world's surgical instruments, the majority of its hand-stitched footballs, and a rapidly growing share of its BJJ gis, rashguards, and MMA shorts — the no-gi side of that output is covered in our companion IBJJF-compliant rashguard manufacturer guide. This concentration creates an industrial ecosystem — shuttle-loom weave mills, EVA foam collar fabricators, woven patch producers, and YKK-certified hardware distributors — all within a 20 km radius of the Sialkot Sample Masters factory floor.
For a BJJ gi brand, this means your full supply chain — weave fabric, foam collar, woven patches, thread, drawstring cord, and care labels — is sourced locally, shortening lead times and giving us cost leverage unavailable to manufacturers who import their own trims. Our 99.8% QC pass rate is built on this supply chain visibility, not just end-of-line inspection.

The Order Process: From RFQ to DDP Delivery
A typical IBJJF-compliant BJJ gi order with Sialkot Sample Masters follows a seven-step workflow that gives buyers full visibility without requiring factory visits.
01
RFQ Submission
Submit your target weave, color, sizing run, branding brief, and estimated quantity. We respond within 24 hours with a preliminary quote and lead time.
02
Tech Pack Review
Our team reviews your tech pack (or creates one from your sketch/reference gi) and marks all patch placements against the IBJJF compliance overlay. Any non-compliant elements are flagged before any cut is made.
03
Pre-Production Sample
A single pre-production sample per colorway is produced in 7–14 days. The sample is weighed post-wash, collar thickness is measured, and dimensional checks are run before dispatch to you.
04
Sample Approval
You test the sample — wear it, wash it three times, submit it to a competition if desired. Revisions are free up to two rounds.
05
Sealed Sample & Bulk Production
Approved sample is sealed and used as the QC reference for bulk. Production runs 25–35 days, with weekly photo updates at key milestones.
06
AQL 2.5 Final Inspection
A statistical sample of the bulk production undergoes our 7-point inspection: dimensions, weight, seam strength, color fastness, collar rigidity, belt loop pull test, and packaging integrity.
07
DDP Dispatch
Cartons are booked on sea freight (16–22 days to USA East Coast, 18–26 days to UK/EU) or air freight (5–7 days) via our freight partner. All customs clearance, import duties, and last-mile delivery are pre-paid — your containers arrive ready for warehouse receipt.
