Hazari Gur of Manikganj: Bangladesh Heritage GI Date-Palm Jaggery — Buyer's Guide (2026)
Hazari Gur of Manikganj — Bangladesh's 64th GI product (June 15, 2026), 200-year-old date-palm jaggery from Harirampur. Distinctive powder-form texture (crumbles in hand), deep amber color, smoky caramel flavor. HS 17023000, 7-point authenticity, 435 food suppliers.
The Hazari Gur of Manikganj — registered as the 64th GI product of Bangladesh on June 15, 2026 — is a distinctive traditional date-palm jaggery (molasses) produced in Harirampur upazila of Manikganj district, situated along the Padma river southwest of Dhaka. The Hazari Gur tradition traces back approximately 200 years to a man named Mohammad Hazari, who reportedly began making this distinctive date-palm molasses in the Jhitka area of Harirampur using a special slow-cooking technique. The product is distinguished from generic date-palm jaggery by its unique powder-form texture (it crumbles into powder when pressed in the hand, unlike the typical block or liquid forms of date-palm jaggery), its deep amber color, its rich caramel flavor with smoky undertones from wood-fired evaporation, and its high mineral content (potassium 2–3%, iron 50–100 ppm). Registered under DPDT GI Journal 64 in the name of the Deputy Commissioner of Manikganj, Hazari Gur is the most recently registered Bangladesh GI product as of mid-2026.

News source: The Financial Express — Hazari Gur of Manikganj receives GI recognition (June 17, 2026)
Manikganj district, situated along the Padma river southwest of Dhaka, has been a traditional date-palm cultivation and molasses-production region for approximately 200 years. The district's specific agro-climatic conditions — winter night temperatures that drop to 8–12°C (cooler than the Bangladesh average due to the inland location away from the moderating Bay of Bengal influence), well-drained alluvial soil of the Padma floodplain, and a long dry season from October to March — create the ideal environment for date-palm sap production. The cool winter nights are particularly critical: they slow the sap flow rate during the day, allowing the tree to concentrate sugars in the sap, and they trigger the natural fermentation-inhibiting chemistry that makes the collected sap suitable for molasses production rather than spontaneous fermentation into palm wine (tari).
The Hazari Gur tradition traces back approximately 200 years to a man named Mohammad Hazari, who reportedly began making this distinctive date-palm molasses in the Jhitka area of Harirampur upazila of Manikganj. The oral tradition, preserved by the Hazari family descendants and documented by the Manikganj district administration in the GI registration application, describes how Mohammad Hazari experimented with the slow-cooking technique and the specific use of the first cold-weather sap collection (called "pohela ras" in Bengali) to produce a jaggery with distinctive powder-form texture and superior flavor. The product developed a reputation across Bangladesh throughout the 19th and 20th centuries, with shipments traveling by river boat along the Padma to the Dhaka and Kolkata markets. Local legend claims that the Hazari Gur's reputation even crossed international borders — some accounts suggest that Queen Elizabeth II of England praised the taste of Hazari Gur during a state visit, though there is no written documentation to confirm this.
By the mid-20th century, Hazari Gur had become Manikganj's signature agricultural product, celebrated in the local saying "Hajari and Baulgan, the real life of Manikganj" (referencing both the Hazari Gur and the Baulgan folk music tradition as the district's two cultural icons). The 2026 GI registration, issued on June 15, 2026, by the Department of Patents, Designs and Trademarks (DPDT) under the Ministry of Industries, formally protected the "Manikganjer Hazari Gur" name under GI class 30 (food preparations). The registration was filed by the then-Deputy Commissioner of Manikganj, Rehena Akter, on February 20, 2024, and was awarded after a 28-month evaluation process. The certificate was issued in the name of the current Deputy Commissioner, Nazmun Ara Sultana. See our Bangladesh Newly Added GI Products (2026) overview for context on this second-wave GI registration, and our Jessore Molasses (Khejur Gur) guide for Bangladesh's other GI date-palm jaggery product.
🏛️ GI Registration and the Manikganj Production Region
Hazari Gur of Manikganj was registered by the Department of Patents, Designs and Trademarks (DPDT) under the Ministry of Industries on June 15, 2026, as the 64th Bangladesh GI product (GI Journal 64). The GI registration protects the name "Manikganjer Hazari Gur" or "Hazari Gur of Manikganj" for the traditional date-palm jaggery produced in Harirampur upazila of Manikganj district using the 200-year-old traditional sap-collection and slow-evaporation technique with the characteristic powder-form texture. The protected production region covers Harirampur upazila specifically — particularly the Jhitka and Gopinathpur areas — with limited extension to the broader Manikganj district where the same traditional technique is practiced. The registration was issued in the name of the Deputy Commissioner of Manikganj under DPDT class 30 (food preparations), making it one of the few Bangladesh GI products registered under a government authority rather than a private cooperative.
Buyers should request a GI registration certificate from the supplier and verify the production location — the GI protection does not extend to date-palm jaggery produced in Jessore (which has its own separate GI registration — see our Jessore Molasses guide), Satkhira, Khulna, Faridpur, Rajbari, or other neighboring districts even when those products use a similar technique. Verification follows the methodology in our GI verification guide.
🌴 Date-Palm Cultivation, Sap Collection, and Hazari Gur Production
The authentic Hazari Gur is produced using a traditional, multi-stage process that begins with the date-palm sap collection in the cool winter season and ends with the distinctive powder-form jaggery. The complete production workflow involves six stages:
Stage 1 — Date-palm tree management: The date palm (Phoenix sylvestris) cultivated in Manikganj is the wild silver date palm, not the fruit-bearing cultivars of the Middle East. The trees are not planted in orchards but rather grow semi-wild along field boundaries, homestead yards, and the banks of the Padma river. A typical Manikganj farming household has 5–15 mature date palms on their land, with each tree taking 12–15 years to reach sap-producing maturity and continuing to produce for 30–50 years. The traditional management involves annual pruning of dead fronds, light soil cultivation around the base, and protection from grazing animals. No irrigation, fertilization, or pesticide application is used.
Stage 2 — Sap collection (the defining winter-season step): The sap-collection season runs from mid-November to mid-March, with the peak season from late December to mid-February. The traditional gachi (sap-collector) climbs the date palm tree at dusk using a waist-loop made of palm-frond fiber, makes a thin diagonal slice at the top of the trunk just below the crown, and hangs an earthen pot (katari) to collect the dripping sap overnight. The gachi returns at dawn to collect the pot before the sap ferments in the warming day. The first cold-weather sap collection (called "pohela ras" in Bengali) is considered the highest-quality and is the sap traditionally used for Hazari Gur — this first sap has the highest sugar concentration and the most complex flavor profile. A single mature date palm can yield 2–5 liters of fresh sap per night during peak season.
Stage 3 — Slow evaporation (the defining technique): The fresh sap is filtered through muslin cloth to remove tree-bark fragments and insects, then poured into a heavy-bottomed copper or iron pan (kata) over a wood-fired stove. The sap is simmered at 90–95°C for 4–6 hours, with the volume reduced to approximately one-fifth of the original. The slow evaporation is critical — rushing it (using higher heat) produces a burnt-flavor product, while extending it too long produces a dry, hard block. The traditional wood fire (using mango or jackfruit wood) contributes to the characteristic smoky undertone of authentic Hazari Gur.
Stage 4 — The powder-form technique (the distinctive step): When the concentrated molasses reaches the correct consistency (it should form a soft ball when a small amount is dropped into cold water), the heat is reduced to very low and the molasses is stirred continuously with a wooden spatula for 30–45 minutes. This continuous stirring, combined with the gradual cooling, causes the molasses to crystallize into the characteristic powder-form texture — it crumbles into powder when pressed in the hand, unlike the typical block or liquid forms of date-palm jaggery. This powder-form technique is the defining characteristic of Hazari Gur and is the unique contribution attributed to Mohammad Hazari 200 years ago.
Stage 5 — Cooling and packaging: The powder-form molasses is spread on a flat metal tray to cool completely, then packaged in airtight containers to prevent moisture absorption (which would cause the powder to clump and lose its distinctive texture).
Producing one kilogram of Hazari Gur requires approximately 10–12 liters of raw date-palm sap, collected from mature date-palm trees during the cool winter season. Total Manikganj district production is estimated at 300–800 metric tons per year, primarily from the Harirampur, Jhitka, and Gopinathpur areas.

See our export documentation guide for the complete document checklist.
✅ Authenticity Verification — Seven-Point Checklist
- Texture inspection: Distinctive powder-form texture — it crumbles into fine powder when pressed in the hand (the easiest visual identifier — Jessore Molasses is block-form, while generic date-palm jaggery is typically liquid or semi-liquid). Block-form or liquid-form product labeled as "Hazari Gur" is not authentic.
- Color inspection: Deep amber to dark amber color (lighter than Jessore Molasses, which is typically darker brown); transparent when held to light in thin layer; very dark brown or black color indicates over-cooking or adulteration with cane molasses.
- Aroma inspection: Complex aroma with notes of toffee, smoke, and dried fruit; the smoky undertone from wood-fired evaporation is distinctive. Absence of smoke aroma indicates industrial production, not traditional wood-fired; presence of sulfurous smell indicates cane molasses adulteration.
- Flavor inspection: Rich caramel flavor with distinctive smoky undertone; clean sweet finish without bitterness; lingering complexity on the palate.
- Mineral content lab test: High potassium (2–3%), iron (50–100 ppm), magnesium, zinc, and B-complex vitamins — significantly higher than refined sugar or cane molasses; testing via ICP-MS or AAS at a recognized laboratory.
- DPDT GI registration: Supplier provides a copy of the DPDT GI registration certificate (GI Journal 64, issued June 15, 2026); the registration is in the name of the Deputy Commissioner of Manikganj, so suppliers should have a usage authorization letter from the Manikganj district administration.
- Manikganj production documentation: BSTI certification under BDS 1135, DAE certificate confirming date-palm sap collection at a Manikganj district address (particularly Harirampur, Jhitka, or Gopinathpur areas), Manikganj Chamber of Commerce membership, and traceability code linking to the producing farm or cooperative.
🏛️ Certifications and Institutional Support
The Hazari Gur supply chain is supported by multiple institutional certifications and agencies. The Bangladesh Standards and Testing Institution (BSTI), under the Ministry of Industries, issues product certification under BDS 1135 (Molasses standard). The Bangladesh Council of Scientific and Industrial Research (BCSIR) provides mineral-content and adulteration testing. The Department of Agricultural Extension (DAE) registers date-palm cultivation. The Bangladesh Food Safety Authority (BFSA) provides regulatory oversight. For EU export, full HACCP certification is required; the British Retail Consortium (BRC) Global Standard for Food Safety is required by major UK retailers. For Middle East export, Halal certification from a recognized Halal authority is required. For organic claims, EU Organic, USDA NOP, or equivalent certification applies. Because the GI registration is held by the Manikganj Deputy Commissioner's office (rather than a private cooperative), the Manikganj district administration plays an active role in supplier verification and quality control — buyers can contact the Deputy Commissioner's office directly for supplier referrals.
Institutional support for export comes from the Export Promotion Bureau (EPB) for market intelligence and trade-fair participation; the Manikganj district administration for production-side coordination (given that the GI registration is held by the DC's office); and the Ministry of Agriculture's Department of Agricultural Marketing for export-oriented production subsidies. Buyers seeking institutional supplier referrals can contact the Manikganj Chamber of Commerce & Industry directly or browse the broader Bangladesh exporters' association directory on BangladeshExport.com.

❓ Frequently Asked Questions
What makes Hazari Gur of Manikganj a GI product?
Hazari Gur of Manikganj was registered as the 64th Bangladesh GI product by DPDT on June 15, 2026 (GI Journal 64, class 30). The registration protects the name "Manikganjer Hazari Gur" for the traditional date-palm jaggery produced in Harirampur upazila of Manikganj district using the 200-year-old traditional technique attributed to Mohammad Hazari. The defining characteristic is the powder-form texture (crumbles into powder when pressed in the hand), which is unique among Bangladeshi date-palm jaggery products and is the distinctive contribution attributed to Mohammad Hazari. The GI registration is held by the Deputy Commissioner of Manikganj, making it one of the few Bangladesh GI products registered under a government authority rather than a private cooperative.
How is Hazari Gur different from Jessore Molasses (Khejur Gur)?
Three main differences. First, texture: Hazari Gur has the distinctive powder-form texture (crumbles into powder when pressed), while Jessore Molasses is typically block-form (soft pliable block called "Nolen Gur") or granular form. Second, color: Hazari Gur is deep amber (lighter than Jessore Molasses, which is typically darker brown). Third, terroir: Hazari Gur is produced in Harirampur upazila of Manikganj district (along the Padma river), while Jessore Molasses is produced in Jessore district (along the Bhairab river). Both are Bangladeshi GI date-palm jaggery products, but they have evolved distinct techniques and characteristics in their respective regions. Hazari Gur also has a more documented origin story (Mohammad Hazari, 200 years ago, in Jhitka) than Jessore Molasses.
What is the HS code for Hazari Gur exports?
Hazari Gur uses HS codes 17023000 (invert sugar, in solid form — primary classification, appropriate for the powder-form texture), 17029000 (sugars nes, including molasses except cane/beet), or 21069099 (food preparations, nes). Most Bangladesh Customs entries use 17023000.
How do I verify that Hazari Gur is authentic Manikganj origin?
Use the seven-point checklist: (1) distinctive powder-form texture (crumbles into powder when pressed); (2) deep amber color (lighter than Jessore Molasses); (3) complex aroma with toffee, smoke, and dried fruit notes; (4) rich caramel flavor with smoky undertone, clean finish; (5) mineral content lab test (K 2–3%, Fe 50–100 ppm); (6) DPDT GI registration (GI Journal 64, issued June 15, 2026) with usage authorization letter from the Manikganj DC's office; (7) Manikganj production documentation (BSTI under BDS 1135, DAE certificate for Harirampur, Manikganj Chamber membership, traceability code).
What is the MOQ for Hazari Gur?
Typical MOQ is 50–300 kg for first-time buyers. Trial shipments of 20–50 kg are available. Bulk orders can reach 2,000–8,000 kg per shipment via sea freight container. Lead time 2–4 weeks from order confirmation, with new-crop availability from late December.
What is the production season for Hazari Gur?
The date-palm sap-collection season runs from mid-November to mid-March, with the peak season from late December to mid-February. The cool winter nights (8–12°C) during this period are critical for sap sugar concentration and for natural fermentation inhibition. The first cold-weather sap collection ("pohela ras") is traditionally used for premium Hazari Gur. New-crop Hazari Gur is available from late December onwards. Off-season supply comes from stored stock — vacuum-packed export grade maintains quality for 12–18 months.
