Supplier controls for licence checks, business verification, notifications and suspicious activity involving regulated or reportable chemicals.
UK suppliers must first establish whether a product contains a regulated or reportable explosives precursor or poison, then apply the controls for the customer and transaction. Those controls can include public licence checks, business verification, written supply-chain notification, record retention and prompt reporting of suspicious activity.[1]
The Poisons Act framework separates regulated explosives precursors, regulated poisons and reportable substances. Classification depends on chemical identity and, for many entries, concentration. Review the current Home Office list against the exact formulation and basis stated, such as weight by weight, available chlorine or total caustic alkalinity. Do not infer status from the product name or transport classification.[2]
Hydrogen peroxide is a regulated explosives precursor at twelve per cent weight by weight; below that threshold it is reportable. Current official entries also include hydrochloric acid at ten per cent, phosphoric acid at thirty per cent and sulfuric acid at fifteen per cent weight by weight as regulated explosives precursors, with lower concentrations reportable.[2]
This matters to pool and cleaning suppliers. A peroxide oxidiser, acidic descaler or pH reducer may be captured even though its ordinary use is legitimate. Sodium hypochlorite is not listed as a regulated explosives precursor and does not require an EPP licence on that basis. However, the current list makes sodium hypochlorite solutions above six per cent available chlorine reportable poisons. Sodium hydroxide at twelve per cent total caustic alkalinity and formaldehyde at five per cent weight by weight are also reportable entries.[2]
A supplier may sell a regulated explosives precursor to a member of the public only where that person has a valid explosives precursors and poisons licence covering the transaction. The supplier must inspect the licence and photo identification, match the person and ID reference, check the authorised substance, concentration and volume, and record the transaction on the licence. If anything is wrong, the sale should be refused and suspicious activity reported.[1]
Regulated poisons are also licence-controlled for public acquisition, possession and use, with additional pharmacy-related supply rules. Build till and online-order blocks around the regulatory classification. A free-text note to “check ID” is not adequate: staff need the sequence, acceptable evidence and escalation path, and remote fulfilment must prevent dispatch until checks are complete.[1]
A genuine business or professional user does not need an EPP licence to acquire a regulated explosives precursor for purposes connected with its trade, business or profession. Before supply, the seller must record the customer's name and address, identify an authorised purchaser, check photo ID, obtain a statement of the trade or public function, record the VAT number where one exists, and assess whether the purchase is reasonably consistent with that activity.[3]
The record must be retained for eighteen months. An earlier compliant record may be reused within that period if it is still held, but transaction consistency still needs attention. Verification can be remote; Home Office guidance gives sending a photo of identification as an example. The process should nevertheless protect personal data and restrict access to staff who need it.[1]
Verification is not the same as ordinary credit onboarding. A VAT number alone does not establish professional use, and a familiar company name does not make an unusual quantity or concentration plausible. Record the intended business use sufficiently clearly for a reviewer to understand the consistency decision.[3]
The 2023 Regulations prohibit supply of a regulated or reportable substance to a business customer unless the supplier first notifies that customer in writing of its status under the Poisons Act. Businesses must also ensure workers involved in these supplies receive information relevant to their roles about the legal requirements, offences and substances supplied.[3]
Place the notification in a controlled document that reliably reaches the buyer before supply. Product data, order confirmation or another written communication may support the process if it clearly identifies the captured substance and status. Flow the information through branches, distributors and online channels; it is not a one-time obligation only for the original importer.[3]
Suspicious transactions or attempted transactions, and significant disappearances or thefts, involving listed regulated or reportable chemicals must be reported within twenty-four hours of discovery. The duty reaches sellers and businesses that use, possess, import or acquire the relevant chemicals professionally, as well as licence holders.[1]
Home Office indicators include an unusual customer, quantity or combination; unfamiliarity with handling; refusal of a lower concentration; reluctance to state the use or provide ID and address; insistence on cash; or unusual packing or delivery requests. The list is not exhaustive. Staff should preserve order, customer and communication records, avoid completing a questionable sale, and use the official reporting route.[1]
Inventory control supports the same duty. Reconcile receipts, decants, production use, samples, damage and dispatch so that unexplained variance can be recognised. Define what operational teams must immediately escalate rather than waiting for a periodic stocktake.[1]
Maintain a current substance register with CAS number, concentration basis, category and threshold. Connect it to product master data so captured lines automatically invoke the correct customer checks and written notice. Review reformulations and legislative list updates; a diluted product and its concentrate may fall into different categories.[2]
Keep a refusal and reporting procedure, train sales, warehouse and customer-service workers, and audit representative transactions. Separate EPP controls from GB CLP, SDS, dangerous-goods and biocides decisions: the regimes can overlap, but compliance with one does not prove compliance with another.[1]
