About Logica Constante, Lda. - Plastic Raw Materials Supplier in Portugal

Portugal‑based Logica Constante, Lda. lists seven active products across five categories: Plastic Raw Materials, Marble & Granite, Pets & Pet Supplies, Aluminium Billets and Aluminium Ingots. The catalogue includes PET Flakes, PET Preforms, a blended PET/PP/PEAD granule, ornamental marble stones, dry dog and cat food, and two aluminium products identified under HS chapter 76 with code 7601.20. The aluminium items are specified as primary unwrought aluminium AL 99.70 % for billets and alloy A7 / ADC12 (minimum 98.5 % aluminium) for ingots. Each entry is presented without additional company history or financial data.

The product set reflects typical export commodities from Portugal, combining polymer recycling outputs, natural stone, pet nutrition, and primary aluminium forms. PET Flakes and Preforms fall under the broader HS 3901‑3902 family for polymer waste and semi‑finished plastics, while the marble stones correspond to HS 6812 for ornamental stone. The dry pet food is classified in HS 2309 for prepared animal feeds. All items are listed with their respective material specifications as supplied by the seller.

Product Range and Specialties of Logica Constante, Lda.

The PET portfolio comprises flakes, preforms and a multi‑polymer granule blend of PET, PP and PEAD. In the recycling industry PET flakes are graded by intrinsic colour (ICUMSA) and melt flow index, with common specifications such as 0.5 - 1.0 % moisture and a melt flow rate of 15 - 30 g/10 min. Preforms are typically produced to ISO 1043 dimensions for beverage containers, with wall thickness tolerances of ±0.02 mm. The blended granule may be used for injection molding, where buyers often request a melt flow index range of 5 - 25 g/10 min and a colour consistency measured by L*a*b* values.

Marble ornamental stones are natural calcite or dolomite blocks, usually supplied in sizes from 100 mm up to 500 mm thickness, with a compressive strength of 70 - 150 MPa and water absorption below 0.5 %. The dry dog and cat food is a processed feed typically packaged in 25 kg or 50 kg bags, with a moisture content under 12 % and a guaranteed protein level of 20 - 30 % for adult diets. The aluminium billets (AL 99.70 %) are primary unwrought shapes used for extrusion, commonly offered in 100 kg to 500 kg bundles, while the A7/ADC12 ingots (Al 98.5 % min) are alloy billets for casting, usually supplied in 200 kg or 1 ton blocks.

Trade and Export Information - Logica Constante, Lda.

Portugal exports plastics and aluminium products primarily to EU markets such as Spain, France and Germany, and to North African and Middle‑East buyers for construction and automotive applications. PET recycling streams are governed by EU REACH registration and often require compliance with ISO 14001 environmental management. Aluminium billets under HS 7601.20 are subject to customs duties based on the EU Common Customs Tariff and may need a Certificate of Origin for preferential trade agreements. Marble stones from Portugal are valued for their low porosity and are frequently shipped in 20‑ft containers with wooden crates, complying with the International Plant Protection Convention (IPPC) phytosanitary standards for stone.

Buyers of dry pet food typically request a feed analysis certificate, HACCP compliance documentation, and a declaration of compliance with EU Regulation 767/2009 on feed safety. Shipping terms for these bulk goods often use FOB or CIF Incoterms, with container loading optimized for weight limits (≈22 t per 40‑ft container).

Sourcing from Logica Constante, Lda. - Buyer Guidance

When sourcing PET flakes or preforms, request a recent melt flow index test, moisture content analysis, and a material safety data sheet (MSDS) that confirms compliance with REACH and RoHS. For the multi‑polymer granule, ask for a blend specification sheet showing the exact PET/PP/PEAD ratios and colourimetric data. Marble stone buyers should obtain a stone certification detailing compressive strength, water absorption, and any surface finish treatment. For aluminium billets and ingots, request a mill test certificate (MTC) that lists alloy composition, tensile strength and extrusion or casting tolerances, as well as a CE marking declaration if the product will be used in regulated sectors.

Dry pet food purchasers should verify a nutritional analysis report, a batch‑level ingredient list, and a compliance statement with EU feed regulations. Across all categories, confirming the supplier’s ISO 9001 quality management certification - or obtaining a third‑party audit report - helps mitigate risk before placing a first order. Sample orders of 500 kg for PET products, 1 ton for aluminium, or a single pallet for marble are common initial quantities to assess quality.

What HS code is used for the aluminium billets and ingots offered by Logica Constante, Lda.?

Both the aluminium billets and the aluminium ingots are listed under HS code 7601.20, which covers primary unwrought aluminium and aluminium alloys.

Which material specifications are provided for the aluminium billets?

The billets are described as Aluminium AL 99.70 % (Primary Unwrought), indicating a minimum aluminium purity of 99.70 %.

What alloy composition is stated for the aluminium ingots?

The ingots are specified as Aluminium Alloy A7 / ADC12 with a minimum aluminium content of 98.5 %.

What typical quality parameters should a buyer check for PET flakes?

Buyers should verify moisture content (≤1 %), melt flow index (15 - 30 g/10 min), and colour consistency using ICUMSA or L*a*b* measurements.

What certifications are commonly required for PET preforms used in beverage packaging?

Common requirements include compliance with REACH, ISO 9001 quality management, and a material safety data sheet that confirms food‑contact suitability.

How is ornamental marble usually packaged for export?

Marble stones are typically crated in wooden boxes with internal padding, loaded in 20‑ft containers, and accompanied by a stone certification indicating compressive strength and water absorption.

What documentation is recommended for dry dog and cat food imports?

A feed analysis certificate, HACCP compliance report, and a declaration of conformity with EU Regulation 767/2009 on feed safety are standard documents.

What sample size is practical for evaluating the PET/PP/PEAD granule blend?

A sample of 500 kg is often sufficient for laboratory testing of melt flow, colour, and polymer ratio verification before larger orders.
