Product overview — Custom NPK Bulk Blend
Custom NPK bulk blend lets importers and national distributors lock in a compound ratio matched to local soil profiles, crop programmes or government tender specifications — without maintaining separate straight-fertilizer inventories at the port. A single granulated product carries your chosen nitrogen, phosphate and potash balance in every prill, simplifying warehouse management and farmer advice compared to on-farm mixing of urea, DAP and MOP.
Production runs on NPK granulation lines at Black Sea complexes, Central Asian plants and MENA toll-blending hubs. Feedstocks include ammonium nitrate or urea for N, MAP or DAP for P, and MOP or SOP for K. The plant granulates the blend to 2–4 mm hardness suitable for mechanical spreaders and rotary planters. Typical buyer segments include agricultural cooperatives tendering for region-specific ratios, distributor chains branding a proprietary formula, and blend plants outsourcing granulation when local capacity is saturated during pre-season peaks.
Submit your target N-P-K analysis, total nutrient floor and chloride tolerance at enquiry. We confirm plant capability, quote blending surcharge where applicable, and issue a mill COA on the finished lot. HS code 3105.20 for compound fertilizers containing the three primary nutrients.

Loading ports & logistics — Custom NPK Bulk Blend
Custom granulated blends — contract MOQ 1,000 MT is met with 1,000 kg FIBC or 50 kg bags in 20 ft and 40 ft dry containers, or on inland coaster and multipurpose vessels from 1,000–5,000 MT to importers without bulk silos. CFR/CIF to Mombasa, Lagos, Chittagong, Karachi and other developing-market ports where buyers re-bag or distribute directly to cooperatives.
Typical bulk custom-blend parcels run 3,000–25,000 MT on handysize and handymax bulk carriers from Novorossiysk, Baltic corridor, Damietta and Jebel Ali. Custom runs require 14–25 days lead time from formula confirmation to first laycan — longer than catalogue grades because the plant schedules a dedicated production slot.
Partial shipments are permitted under multi-laycan bulk contracts when the buyer staggers discharge across two ports. Colour and bag printing with buyer branding are available on orders above 2,000 MT bagged.
Packaging & documentation — Custom NPK Bulk Blend
Each lot ships with a mill certificate of analysis confirming actual N, P2O5, K2O and moisture against the contracted formula. SGS or equivalent pre-shipment inspection at load port is arranged on request. Standard export set: commercial invoice, packing list (bagged lots), bill of lading, certificate of origin and phytosanitary certificate where destination customs requires it.
Payment: irrevocable LC at sight or CAD for first-time buyers; established accounts may negotiate open-account terms. Formula changes mid-contract require a written amendment — the plant cannot switch N-P-K ratio within an open hold without full hold cleaning and re-blending.
FAQ — Custom NPK Bulk Blend
What N-P-K ratios can be produced as a custom bulk blend?
Most granulation plants accept formulas from 10-10-10 through 24-8-7, with total nutrient content between 35% and 48%. Ratios outside standard catalogue grades — such as 14-7-21 or 18-12-6 — are quoted on request. Submit your target analysis and we confirm plant capability before firm pricing.
Can micronutrients be included in a custom NPK bulk blend?
Yes. Boron, zinc, copper and manganese can be incorporated at 0.1–2.0% total micro-element content via pre-mix addition at the granulation stage. Specify the micro package at enquiry — formulations with sulphur or magnesium oxide are also available on integrated lines.
