In-House Durian Processing vs Outsourced Hubs in SG

In-House Capex: Rent, Blast Freezers, and SFA Layouts

A ground-floor unit at FoodX@Senoko or NorthLink Building runs SGD 3.50 to 6.00 psf per month. For a 2,000 sqft processing room, that is SGD 7,000 to 12,000 monthly before utilities, pest control, and pest control audits. Fit-out cost is the real killer: stainless steel wall cladding, graded drainage, a chiller vestibule, and a separate dirty-side receiving bay pushes CAPEX to SGD 250,000–500,000, particularly if SFA’s layout inspectors mandate a physical break between the fruit wash zone and the packaging room.

Equipment on the lower end of seriousness: a 200 kg/hr helical blade destoning pulper (SGD 18,000–25,000 from Chinese lines via Johor distributors), an HTST pasteuriser for pulp if you plan to sell into foodservice (SGD 35,000+), and a blast freezer that takes 50 kg of pulp from 30°C to −18°C in 3.5 hours (SGD 80,000–120,000). The breakeven only makes sense if you process at least 500 kg of whole fruit per day, six days a week. Below that throughput, the chilling capacity sits idle and the rent is pure leak.

Johor Outsourcing: Co-Packing Rates and Crossing Schedules

Johor co-packers, clustered around Pasir Gudang and Ulu Tiram, quote RM 2.80–4.50 per kg FOB for de-seeded frozen durian pulp. That price includes their HACCP line, eHalal certification, and labour. Add logistics: a 3-tonne cold truck crossing the Tuas second link costs RM 450–600 per trip with the Customs transit permit, and your imported pulp needs an SFA import permit filed through TradeNet before the truck queues at the causeway.

The landed cost of outsourced pulp in Singapore usually lands at SGD 5.80–8.20 per kg, depending on whether the co-packer does the pre-freezing or you handle blast freezing locally. The critical operational difference is lead time. A scheduled weekly slot at a Johor hub gives you a 3–5 day turn-around from whole fruit to frozen pulp at your Senoko cold room; an in-house line gives you 4 hours. If you are serving Orchard Road restaurants that place orders at noon for next-day delivery, outsourcing forces you to forecast one week ahead.

SFA Contract Rules: Whose Licence Fails First in a Recall

Processing in-house means your SFA food establishment licence, your HACCP plan, and your incident report when a microbial failure hits. Outsourcing shifts primary licence risk to the co-packer, but your brand stays liable under ordinary product liability law if a batch is sold under your label. Co-packing agreements in this trade routinely include a 48-hour microbial hold for E. coli and coliform testing at the laboratory of the importer’s choice, release notes, and a quarantine clause for 20% of each batch until lab reports clear.

The paperwork has a separate spine. A co-packer’s certificate is fine for re-export, but if the pulp is repackaged into retail pouches in Singapore, you need to register the product’s labels and the establishment addresses via the GoBusiness licensing portal. The free sales certificate for exporting to Hong Kong or Taipei gets easier if you are the licensed SG manufacturer, not a middleman buying from a Johor hub. In practice, the cleanest liability split is: Johor hub cuts and defleshes, your SFA-licensed premises blast freezes, tests, and packs.

Yield Math: Stick to 32% Pulp, Not 40%

Fresh Musang King grades at 300–350 g of flesh per kg of whole fruit, a 30–35% yield depending on ripeness and how aggressively the stoning line scrapes the seed husk. Many in-house lines over-scrape to fatten per-kg output, which folds fibrous astringency into the pulp and kills the selling price. A skilled operator gets 32% without fibre pickup; a rushed one gets 38% with noticeable endocarp shreds.

Unit economics at 32% yield: if your in-house overhead (rent, labour, power, lab tests, equipment depreciation) lands at SGD 18.00 per kg of finished pulp, you beat outsourced hubs only when you process more than three tonnes per month. Below that, outsourcing at SGD 7.20 per kg landed is strictly cheaper. The trade-off is control over ripeness staging. Johor hubs often blend fruit from different farms to guarantee consistency, so a single-origin brand that wants only Pahang Raub fruit sees a premium of RM 1.20–1.50 per kg on the raw material side.

Hybrid Drop-Point: Blast Freeze at Senoko, Bulk Deflesh at Pasir Gudang

The workable compromise in SG is to buy whole fruit, pay a Johor partner to wash, cut, and deflesh, then truck the pulp back to your Senoko unit for blast freezing, finished-pack packing, and export documentation. This keeps heavy labour where it is cheap, keeps the legal exporting label from Singapore, and keeps your blast freezer utilisation high enough to justify its CAPEX. Cold chain integrity is the deciding variable: each truck crossing spends 45–70 minutes in causeway queue queue, so the pulp must be pre-cooled to below 5°C at the Johor side and the Tive T11 data loggers should be inspected before the truck clears customs.

Traceability is a manual mess unless you fix it digitally. Use a lot-numbering scheme that ties the Johor batch cut to the SG blast freeze cycle, and record it in a system with FIFO logic such as QuickBooks Commerce or Sage 300, not an Excel sheet. Those platforms handle the free sales certificate support files and the factory reconciliation when SFA asks which raws went into which export batch. The hybrid model only works if both partners agree to the same 24-hour cold chain window or the pulp degrades faster than the paperwork does.
