MOP fertilizer price Malaysia: 50 kg bags and delivery
Decision details
Fits if: Buyers who want to compare two dated MOP asking figures and calculate upfront spend and leftover pack quantity.
Main drawback: Two separate listings, not a matched quote or transaction. Current price, delivery, availability, product match and physical labels have not been verified.
Compare: Match the product and net weight; request the full label, available quantity, dated price, delivery to your postcode, final total and payment terms from the supplier.
In this guide
Two e-commerce asking listings dated 2026-10-02 state RM10.00 for a 1 kg pack and RM325.00 for a 50 kg pack; these are separate seller observations, not matched quotations or prices for today [source] [source]. The per-kg calculations exclude delivery. No wholesale asking was recorded in this capture; that does not prove no wholesale offer exists.
What does MOP mean, and when might it fit?
MOP (muriate of potash) is a common fertilizer name for potassium chloride (KCl); the University of Maryland Extension reference lists MOP at 0-0-60. This general definition does not confirm the contents or grade of a particular listing or bag. An NPK product supplies N, P2O5 and K2O according to its label, while MOP is a potassium source rather than a replacement for a whole NPK programme. If a nutrient plan calls for potassium without extra N or P from the product, MOP is one option; this price page does not set a crop recommendation or application rate 1.
MOP or SOP: choose for the K, chloride and sulphur requirement
MOP is potassium chloride (KCl); SOP is potassium sulfate (K₂SO₄). Both supply potassium, while SOP also supplies sulphur and avoids adding chloride from that product. That can matter when soil/water results, a sulphur need or crop guidance makes chloride relevant. It does not mean every crop must avoid MOP: Penn State Extension describes crop-dependent considerations, and a UGA pepper trial in a specific system found no overall-yield difference by K source. That result is not a recommendation for a Malaysian crop or farm 2 3.
Match the soil/water test and nutrient plan to the product label before choosing. Check product form, grade and application method too: a manufacturer-documented water-soluble SOP product does not make every SOP bag suitable for fertigation; system fit depends on the actual label and manufacturer instructions 4. If a crop or agronomy recommendation identifies chloride as a concern, ask whether SOP addresses that requirement; otherwise compare the cost of the same K₂O unit and the actual sulphur need.
For a fair price comparison, request dated quotes for the same quantity and delivery basis. Calculate cost per kg K₂O = product total ÷ (net weight × the label K₂O fraction). Conditional check: if the offered 50 kg MOP bag actually declares 60% K₂O, RM325 ÷ (50 × 0.60) = RM10.83/kg K₂O before delivery. RM325 is a dated listing observation, and the listing title alone does not verify the physical label. For SOP, use the bag’s declared K₂O percentage and an actual quote; do not assume every SOP grade is 50% or compare bag prices alone. Sulphur, chloride, solubility and leftover quantity also affect fit, so nutrient cost is only one criterion [source] 4.
Where can you enquire about MOP in Selangor?
The price capture above does not identify a seller or location. Separately, official supplier websites for three Selangor-based companies list MOP or potassium chloride in their product ranges. These are enquiry leads, not confirmation of today’s stock, a specific 0-0-60 pack, price, bulk quantity or delivery to your address.
| Supplier and published information | Published location/contact | What still needs confirmation |
|---|---|---|
| NPK International lists Muriate of Potash (MOP) and describes itself as a fertilizer wholesaler/distributor serving retailers, estates and plantations. | Port Klang, Selangor; 012-229 9076 | Whether MOP is currently available, the full label, pack/quantity, price, direct or dealer sale, and delivery cost. |
| Obetech Pacific lists potassium chloride (MOP) on its fertilizer page. | Klang, Selangor; +603-3344 6270 | Actual grade and label, pack, minimum quantity, dated price and whether delivery to your postcode is available. |
| Twin Arrow Fertilizer says it imports and supplies straight fertilizers including MOP; its corporate page also lists oil palm among its supply sectors. | Shah Alam, Selangor; +603-3359 7711 | Whether its listed MOP can be bought in the grade and quantity you need, plus price and delivery terms. |
These details come from supplier websites; they are not independent stock or offer checks. In particular, the two dated price-list titles above say “MOP 60%” only, not a physically verified 0-0-60 label. Contact each channel and request a full label photo and dated quote stating net weight, available quantity, delivery to your postcode and the final total. Compare only products with matching label details and units.
What did the two dated MOP listings show?
| Listing title and stated pack size | Dated asking | Per-kg calculation before delivery |
|---|---|---|
| Potassium Chloride / Muriate of Potash MOP 60% (Agricultural Grade), 1 kg | RM10.00 / 1 kg, asking, 2026-10-02 [source] | RM10.00/kg |
| Potassium Chloride / Muriate of Potash 50kg MOP 60% K (Agricultural Grade) | RM325.00 / 50 kg, asking, 2026-10-02 [source] | RM325.00 ÷ 50 kg = RM6.50/kg |
Per-kg gap: RM10.00 − RM6.50 = RM3.50/kg between the 1 kg and 50 kg listings on the same day. [source] [source]
What is the upfront spend and leftover quantity?
This calculation uses two separate 2026-10-02 asking listings, not matched quotations. Prices exclude delivery, discounts, verification of the physical labels and current stock.
| Planned quantity | 1 kg listing at RM10 each | 50 kg listing at RM325 | Reading the upfront total |
|---|---|---|---|
| 20 kg | RM200 | RM325; 30 kg left | The 1 kg listing requires less upfront cash if you need only 20 kg. |
| 33 kg | RM330 | RM325; 17 kg left | The bag total is slightly lower at displayed asks, but buys 17 kg extra. |
| 50 kg | RM500 | RM325 | The bag is RM175 lower before charges if all 50 kg is used. |
Product-price totals meet at about 32.5 kg (RM325 ÷ RM10/kg), before delivery. Use this as a budget screen only; match the product and label, request a dated delivered total, and consider how any remainder would be stored.
What should you ask before buying MOP?
- Can the seller send a full label photo, including grade/analysis and net weight?
- Is it in original or repacked packaging, and who is named as manufacturer/seller?
- What quantity is available and what is the dated price for my quantity?
- What is delivery to my postcode, any minimum order, and the final total?
- Does the quote name the same product and label that will be delivered?
Copy and send to a seller: “Hello. I’m looking for MOP delivered to postcode _____. Could you send a full label photo and a dated quote for _____ kg/bags? Please state net weight per bag, quantity available, whether packaging is original or repacked, delivery charge, minimum order and final total. Will the delivered product label match the photo?”
This page does not take MOP quotation requests and cannot confirm stock or delivery. Ask a seller you choose for a dated quote that includes delivery to your location.
For dated examples of compound NPK prices, see Malaysia’s NPK price table. Those are separate products, not MOP comparisons.

Frequently asked questions
What is the difference between KCl/MOP and NPK?
MOP (muriate of potash) is a common fertilizer name for potassium chloride (KCl); the Extension reference lists it as 0-0-60. That general definition does not verify a particular bag. NPK supplies N, P2O5 and K2O according to its label; MOP is a potassium source, not a complete NPK programme. If your nutrient plan calls for K without extra N or P from this product, MOP is one option—not a crop-specific recommendation or rate [^umd-mop] [source].
What is the price of MOP fertilizer 50kg?
An e-commerce listing dated 2026-10-02 stated RM325.00 asking for a 50 kg pack [source], or RM6.50/kg before delivery. This is a listing ask, not a transaction or current price.
And the 1kg MOP price?
An e-commerce listing dated 2026-10-02 stated RM10.00 asking for a 1 kg pack [source], or RM10.00/kg before delivery; this is not a transaction or current price.
Are MOP and KCl the same thing?
MOP is the common fertilizer name for potassium chloride (KCl), listed as 0-0-60 in the Extension reference. This is a general definition, not verification of a listing or bag; check the actual product label before buying [^umd-mop].
What can these two asking listings tell you?
On 2026-10-02, one 1 kg listing stated RM10.00/kg and one 50 kg listing stated RM6.50/kg before delivery [source] [source]. The gap does not establish packaging or postage as its cause; these are not matched quotations.
Where can I enquire about MOP in Selangor?
NPK International in Port Klang, Obetech Pacific in Klang and Twin Arrow in Shah Alam list MOP or potassium chloride on their supplier websites. Contact them directly to confirm the label, stock, price and delivery; their pages do not prove a current offer.
